Abstract
The invention relates to a solvent-based adhesive, in particular to a solvent-based adhesive for a CPVC (Chlorinated Polyvinyl Chloride) material. The adhesive includes the following components in parts by weight: 15-28 parts of CPVC resin, 120-165 parts of low toxicity solvent and 0-15 parts of thickening resin. On the one hand, the adhesive disclosed by the invention has better properties of adhesion and heat resistance, lower cost of all components and stronger product competitiveness; on the other hand, because the low toxicity solvent is adopted, the adhesive disclosed by the invention can be used for bonding a water supply CPVC pipeline systems, does not influence the water quality after solidified, thereby being consistent with the trends of health and environment friendliness.
Description
Technical field
The present invention relates to solvent-based adhesive, specifically is the solvent-based adhesive that is used for the CPVC material.
Background technology
CPVC (chlorinated polyvinyl chloride) is by the chlorination modified a kind of novel high polymer elastomer material between rubber and plastics that makes of PVC (polyvinyl chloride).This product is white or faint yellow tasteless, odorless, nontoxic loose particles or powder.PVC is behind superchlorination, and the irregularity of molecular linkage increases, and polarity increases, and makes solvability increase, and chemical stability increases, thereby has improved the corrosion of the thermotolerance, acid-and base-resisting, salt, oxygenant etc. of material.Therefore, CPVC is a kind of model engineering plastic that has a extensive future.
The CPVC pipe connection adopts bonding way usually.This mode adopts solvent-based adhesive to be coated in respectively needs bonding pipe outer surface and pipe fitting internal surface, and pitting needs gluing of surfaces, and then by certain reactive force two surfaces is merged.In addition, the resin in the tackiness agent helps to fill the gap, and accelerated solidification reduces and shrinks and internal stress, strengthens the bounding force of tubing and pipe fitting.Yet do not have open source information at present about the solvent-based adhesive that is specifically designed to the CPVC pipe connection.
On the other hand, about the tackiness agent that is applicable to hard PVC more report is arranged then.For example: " development of PVC-U tubing tackiness agent " (Hu Aizhu, Jianping YANG, the Zhejiang chemical industry, 2000,31 volumes, the 4th phase) having introduced with butanone, pimelinketone, dichloro hexane is that mixed solvent dissolving CPVC and PVC base-material obtain the good PVC-U tubing solvent-based adhesive of a kind of intensity." development of modified hard PVC tackiness agent " (Chu Heng Chen Xu is bright etc., the Hubei chemical industry, 1999 the 4th phases) introduced the CPVC that adopts ethylene dichloride, tetrahydrofuran (THF), trieline, pimelinketone, the dissolving of dimethylbenzene equal solvent EVA, CPE, CEPDM modification and the hard PVC tackiness agent that makes a kind of excellent property.Chinese patent CN 200610035322.5 discloses a kind of low-toxicity solvent adhesive that is used for bonding of rigid PVC plastic pipeline system.
Though above-mentioned tackiness agent also can be used for the CPVC pipe connection, also comes with some shortcomings:
(1) adhesiveproperties of the solvent-based adhesive of PVC class is relatively poor, and it is not very desirable therefore adopting this class tackiness agent to come bonding CPVC tubing and pipe fitting effect.
(2) portioned product has been ignored the pollution of solvent toxicity to conveying water quality, is extensive use of poisonous products such as ethylene dichloride, dichloro hexane, toluene, trieline and makees solvent.
(3) the in addition individual defective of these PVC kind solvent type tackiness agent is exactly thermo-labile.Because the resin-oatmeal of its filling is based on polyvinyl chloride resin powder or modified PVC resin-oatmeal, it is low to solidify post softening point, is not suitable for the occasion that the CPVC tubing system is used for the delivering hot water.
Therefore providing a kind of toxicity solvent-based adhesive low, that be specially adapted for the CPVC material is technical issues that need to address.
Summary of the invention
First technical problem that the present invention solves provides a kind of solvent-based adhesive of the CPVC of being specially adapted for material, this tackiness agent not only toxicity is lower, and have preferable adhesive property, resistance toheat, make that the CPVC tubing system of this tackiness agent of use is more safe and reliable.
For solving the problems of the technologies described above, the present invention adopts technical scheme to be:
A kind of solvent-based adhesive that is used for the CPVC material, this tackiness agent comprises the component of following parts by weight: CPVC resin 15-28, low-toxic solvent 120-165, resin of thickening 0-15.
As one of improving: described low-toxic solvent comprises one or more in pimelinketone, butanone, the ethyl acetate.
As two of improvement: the parts by weight of described each component of low-toxic solvent are: pimelinketone 60-70, butanone 55-80, ethyl acetate 5-15.
As three of improvement: this tackiness agent also comprises stopping composition, and this stopping composition is one or more mixtures in lime carbonate, kaolin, the polynite.
As four of improvement: the parts by weight ratio of described stopping composition is less than 10%
As five of improvement: described resin of thickening is one or more mixtures in modified phenolic resins, terpine resin, the modified rosin resin.
Compared with prior art, the invention has the beneficial effects as follows:
(1) adhesiveproperties of tackiness agent of the present invention and resistance toheat are preferable, and each component cost is lower, has stronger product competitiveness.
(2) tackiness agent of the present invention adopts low-toxic solvent, and the CPVC tubing system that can be used to feed water is bonding, does not influence water quality after the curing, meets health environment-friendly trend.
Embodiment
Each component is made it to become solution or colloid behind the uniform mixing by weight proportion, can make the solvent-based adhesive of the CPVC of being used for material of the present invention.Concrete component and the part by weight of embodiment 1-3 are as shown in table 1.
Table 1
Respectively the component uniform mixing of above-mentioned three embodiment is made into the liquid with certain viscosity and can obtains being applicable to CPVC material, the especially tackiness agent of CPVC pipe bonding.Owing to do not adopt the higher material of toxicity in the component that the various embodiments described above adopt, and each component can not react the generation highly toxic substance, and therefore the tackiness agent toxicity that finally obtains is lower.
In the above-described embodiments, except being suitable for tert butyl phenolic resin and modified rosin resin as the thickening material, the modified phenolic resins that can also use terpine resin, other types is as thickening material.These resin of thickening both can use separately and can multiple mixing use.In addition, can also use other stopping composition commonly used in the above-described embodiments, for example kaolin, polynite etc.These stopping composition equally both can be used alone, but also also mix together, but the blended ratio had better not surpass 10%.
Table 2 is to use the tackiness agent of above-mentioned three embodiment to come bonding CPVC tubing and the measured mechanical performance data of pipe fitting respectively.
Table 2
[1] CPVC tubing, pipe fitting stick with glue agent bonding after, after regulating 2 hours under 23 ± 2 ℃ of conditions, begin experiment immediately.
[2] CPVC tubing, pipe fitting stick with glue agent bonding after, after regulating 2 hours under 80 ± 2 ℃ of conditions, begin experiment immediately.
[3] CPVC tubing, pipe fitting stick with glue agent bonding after, to leave standstill at normal temperatures 1 day at least, after leaving standstill 4 days under 80 ± 2 ℃ of conditions, just begin then the experiment.
Mechanical property experimental results shows that CPVC tubing of the present invention, pipe fitting adopt the tackiness agent of embodiment 1-3, have higher intensity and resistance toheat, meet the industry technology standard-required, also satisfy actual service requirements.On the other hand, the cost of embodiment 1-3 prescription is low, meets practicality and the requirement of economic row, has than high performance-price ratio, and very strong marketing prospect is arranged.
