Photoluminescent products, in particular for coating various surfaces and applications.

The present invention relates to photoluminescent products intended to be applied to overhanging surfaces, in particular to be made visible at night after exposure to daylight or to an artificial light source. The photoluminescent products already known and in particular described in patents FR-2,566,791 and FR-2,563,197, are marketed in the form of panels and adhesive tapes to which the product has been previously applied. These panels are fixed on - surfaces to be made photoluminescent. They are produced using a photoluminescent synthetic material based on polypropylene and / or polyethylene, or a hardened mixture of acrylic resin 5 to 15%, acrylic liquid 40 to 60%, pigments 25 to 40% and material absorbing ultraviolet rays, 5 to 15%. The pigment consists of the following components: Zπ S: Cu; Zn s: O: Mn; Zn2 S: 0: Mn; (Zn, Mg) 0: Zn S and a material which at least partially absorbs UV rays and a stabilizing material.

These products are particularly expensive and not very flexible to use because of their presentation in the form of panels and adhesive tapes. In addition, the mechanical qualities of these products are insufficient for their use in flooring.

The object of the present invention is to remedy these drawbacks. The invention ^" , as characterized in the claims, solves the problem of creating an easy-to-use mixture, adaptable to all cases of coating surfaces of all kinds and all vocations, characterized in that said mixture comprises: - a transparent or translucent mono or bi-component base, with or without hardener, said base acting as a binder and constituting approximately 30% of the mixture, - n photoluminescent pigment constituting 0.1 to 50% of the mixture, as the case may be. - a transparent or translucent filler constituting 20 to 75% of the mixture, an average of 30%,

. hydrocarbon resins; . pseudo translucent bitumen etc.

- a photoluminescent pigment with long refraction, radioactive or not, depending on the activator used for coloring, 20 to 70%, average 30%. In the case where radioactive pigments are used, these are coated in the base, in the hardener or in the plasticizing agent. The pigments are never found on the surface of the wear layer, in particular for the bristles, in order to avoid any risk of pollution, even after destruction of the support materials, these being recovered for the constitution of embankments or others;

- a transparent or translucent filler: 20 to 50%, average 30%, which can consist of:

. solid microbeads in glass from 5μ to 850μ solid or hollow which can be tinted in the mass; . solid glass beads of 0.05mm to 1.25mm diameter;

. crushed glass, colored or not, recovery or not; transparent or translucent beads made of organic material, PVC etc .;

. aggregates made of transparent or translucent material, colored or not;

. colored or not colored glass powder, etc.

. colored or not colored quartz powder;

. metallic or non-metallic flakes for decoration;

- additive agents, 0.1 to at least 10% and more:. filters depending on the nature of ambient UV, natural or electric; . plasticizers intended to provide flexibility depending on the nature of the support in order to avoid subsequent cracking of the coating; accelerator or retarder added on site to the mixture according to the installation conditions, cold or hot, dry or wet ambient temperature;

. bubble separator to prevent the formation of bubbles which adversely affect the surface finish and the quality of the coating; . of surface tension of the mixture to ensure the finish at the time of installation.

Preparation of the supports before the installation of the adapted coating:

- Concrete: cleaning, dusting, elimination of laitances (small skin that forms on the surface of concrete) and fatty traces by mechanical brushing, planing, sandblasting or shot blasting.

- Wood: cleaning, degreasing, dusting.

- Metals: degreasing.

- Fabrics, degreasing, dusting.

- Plastics: degreasing, dusting. for all types of supports, prior to the implementation of the luminescent mixture, first a so-called primary layer is applied, tinted united in the clearest possible tone.

Preparation of the constituent mixture of the product according to the invention:

For all uses, specifications are drawn up from a grid for entering parameters of the nature of the support, the environment, the characteristics of use, and the surface footage to be covered. The mixture is dosed in quantity and in quality according to the requirements of said specifications so as to adjust the product exactly as needed. Indeed, it is hardly possible to provide a standard product. These are generally industrial, administrative or public premises, large areas, the minimum size of which is on the order of a thousand m2. Consequently, the dosages always relate to large quantities which hardly involve additional costs compared to standard and versatile products for specific repetitive uses. The pigments are dosed in boxes, the charges in sealed bags, the base and the hardeners of the base are dosed in barrels, the plasticizers and additives are included in the base. The product is sold pre-dosed for each site; the mixture of the various pre-dosed constituents is mixed at the last moment directly on the site.

Specific characteristics of the products according to the invention according to the nature of the support and the type of use:

- Raw concrete: any base can be laid on concrete as long as the construction shrinkage joints are kept. These joints are treated with an elastomer product to seal it. The specific characteristics of this coating can be for example:. Resistance to compression, punching, abrasion; anti-slip, anti-acid etc. These characteristics are obtained according to the choice of the binder (for example epoxy with good wetting power) with a percentage of charge of the order of 70% and a coating thickness of 1 to 5 mm . A crystalline powder pigment is preferably chosen. The non-slip function is obtained with a filler preferably made up of ground glass powder. The anti-acid function is ensured by the choice of binder. At the time of laying, depending on the temperature, hot or cold and the humidity, -an additive is added to the binder to soften or harden it in proportions of 0.1 to a few percent.

- Coating on steel or other metal: the base is chosen according to the coefficient of expansion of the metal, its flexibility and the desired protection (anti-corrosion, anti-acid, anti-shock, personal safety). The anti-corrosion and anti-acid functions are ensured by the choice of binder. The anti-shock function is ensured by the nature of the filler, hard or extra-hard, for example glass beads. The personal safety function is obtained by the presence, of the order of 70 to 90%, of elastomer in the load.

- Coating on wood, same characteristics as on steel. In all coating cases, a first layer or primary bonding layer is applied depending on the nature of the support. - Asphalt: We put a safe coating on this type of support to level it, decorate it, make it anti-dust and anti-grease. The surface must not attack the asphalt, which excludes the use of solvents. In general, the layer is thin, of the order of 1mm. Depending on the characteristics chosen, the thickness can range from l to 5mm.

- Coating of floors and walls or food supports: Food quality is obtained in the absence of solvent in the constituent mixture of the product. Are excluded in particular polyurethane, metacrylate, hydrocarbon resins. When the coating is placed before the food equipment is put into service, this quality is obtained, even with the products excluded, after polymerization of the mixture. On the other hand, it is strictly forbidden to use them after the premises have been put into service, for example for repairing the floors. Epoxy and acrylic bases, for example, have food quality.

- Coating of walls and vertical surfaces, panels etc.: The specific characteristics which can be requested are for example the following: anti-acid (according to the choice of binder), waterproof (the coating product according to the invention is always waterproof ) , light intensity

(function of the percentage of pigments in the mixture), decoration (choice of color of the pigment and of the fillers, glitter, granules, mother-of-pearl, etc.), anti-graphitti (this function is obtained by means of a layer of finish which ^" allows the cleaning of the coating with a sponge). - Pool coating. The characteristics are generally as follows: Waterproof and rot-proof (the product is naturally waterproof and rot-proof), aesthetic decor (all decor variations can be offered depending on the choice of pigments and filler).

- Formulation of the mixture according to the mode of application, in particular on vertical surfaces which require less mechanical characteristics than the grounds: The percentage of the translucent or transparent load is reduced for the application with the roller and the brush. For spray application, a little alcohol or solvent is added to further thin the mixture when the use of solvents is possible (excluding food). Several coats will be required. If the wall has to be straightened because its surface is dented or crooked, a highly tixotropic mortar is used which will give a coating which is easy to apply to the trowel.

- Light intensity and duration of photoluminescence after exposure to a natural or artificial light source: it is a function of the nature and the re anence of the pigment, of the quantity used in the mixture and of the quality of the filtering agent used to trap UV. Example according to the invention of the composition of a photoluminescent floor covering of the tiling, plinth, flashing type industrially produced by injection, extrusion or by casting molding:

- hot binder with very rapid polymerization 10 to 25%

- photoluminescent pigments 5 to 25% particle size about 40μ

- transparent filler: glass or organic beads diameter 5μ to 1.25mm 45 to 75% - plasticizer 0.01 to 10%

- reactive or not 0.01 to 5% depending on the manufacturing method and the type of product TOTAL 100% The filler, glass beads or organic matter, 5μ to 1.25mm, acts as a decoration and resistance to abrasion. It is the binder, epoxy, polyester, polyurethane, or organic which is photoluminescent. As a variant of the above mixture for tiles, plinths, flashings, the load consists of aggregates of marble, granite or quartz from 0.5 to 4mm in diameter.

It is planned to make all types of mixtures for photoluminescehts coatings in the mass, of thickness from 1 to 5mm, using in said mixture, a photoluminescent filler consisting of organic spheres, or glass or "airgel" base Si02 or hollow, with a diameter of the order of 5μ to 850μ which can go up to 1.25mm, colored in the mass in manufacture, by means of photoluminescent pigments, colored or not, from lμ to 5μ. It is then no longer necessary to add photoluminescent pigments to the binder.

As a variant, the transparent or translucent fillers for photoluminescent coatings in the mass, 1 to 5 mm thick, consist of organic spheres, or glass or "airgel", solid or hollow, coated in the factory with photoluminescent pigments of grain size from lμ to lOμ, with a diameter of 0.005 to 1.25mm. As in the previous case, it is no longer necessary to add photoluminescent pigments to the binder. This simplifies preparation on site or in storage.

As a variant, the transparent or translucent fillers for mass photoluminescent coatings, 1 to 5 mm thick, are produced using crushed, transparent or translucent aggregates, of glass, marble, granite, quartz or the like, with a diameter of 0 , 5 to 4mm, coated, at the time of manufacture in the factory, with photoluminescent pigments of particle size from lμ to lOμ.

Example of composition of a colorless photoluminescent varnish applied in a film-forming layer, for the finishing of thin or thick coatings of all types of surfaces: floors, walls, building ceilings, various sheet metal work, vehicles and others: - Polyurethane base, or epoxy, or acrylic, or metacrylate or similar 85 to 99.9%

- photoluminescent pigments 0.1 to 15% particle size from lμ to lOμ To increase the effect of the photolu inescεnce, the above colorless varnish can be applied in several successive layers according to the desired result.

To make objects made of thermoplastic materials photoluminescent, photoluminescent pigments with a particle size of the order of 40μ and an amount by weight of 5 are added to the constituent mixture, during the manufacturing phase, injection, extrusion, molding. 10% of the mixture.

Photoluminescent clothing or, depending on the use, both photoluminescent and fluorescent in the mass, are produced by adding to the constituent mixture extruded in sheets, photoluminescent and / or fluorescent pigments of the corresponding color, with a particle size of lμ to 10 μm maximum and an amount by weight of 5 to 10%. The grain size should not exceed lOμ and rather below to keep the flexibility of the garment.

Bulk photoluminescent tapes or, depending on the use, both photoluminescent and fluorescent, in thermoplastic material, self-adhesive or not, are obtained in the same way by adding photoluminescent pigments of the appropriate color, in the mixture with extrude. The particle size of the pigments is from lμ to lOμ maximum to maintain the flexibility of the material, of an amount by weight of 0.5 to 15% relative to the base which can be constituted by any common thermoplastic material of a dosage of 99.5% to 85%.

The photoluminescent mixture in the mass, intended for the production of tiles, plinths and flashings, is also used for the manufacture of furniture molded by injection or molding by casting. These pieces of furniture and equipment can be tables, benches, cupboards, shelves incorporated or not into panels, decorative panels and wall protectors, panels for covering tables and worktops, sinks, washbasins, WCs, baths, etc. To consolidate the mixture, glass fibers or other usual stiffening materials are added.

This mixture is also used for the realization

1 of safety boxes for electrical installations and various fluids, pneumatic, hydraulic.

It can also apply to any molded object that must be easily found or visible in the dark. Electrical battery box, door or frame, electrical switch boxes for the building and industry, signaling components to stick to delimit obstacles in the dark, especially for mobile objects, vehicles and others, bumpers vehicles and other plastic parts.
