Definitions
- the present invention relates to an aqueous composi ⁇ tion for coating, such as surface sizing or application of a layer of a coating slip, of cellulose-based two-dimensional products.
- the composition has improved properties at in ⁇ creased temperatures and at high shear rates. These proper- ties are achieved by using as thickening agent a cellulose ether, which is substituted with hydroxyalkyl groups, such as hydroxyethyl and hydroxypropyl, and alkyl groups having 1-3 carbon atoms.
- the coating slip compositions can, in addition to binder and pigments, also contain secondary binders (co-binders) , protective colloids, thickening agents and dispersing agents.
- secondary binders co-binders
- protective colloids thickening agents
- dispersing agents As thickening agent, protective colloid or secondary binder it is common to add water-soluble or water-swellable polymers based on polyvinyl alcohol, modified celluloses, starch, casein, alginate or high-molecular carboxyl-group-containing poly- merisates.
- cellulose ethers in coating slips is dis- closed in e.g. EP 15 517, where carboxymethylcellulose is added as a secondary binder. From EP 307 795 it is known to use as protective colloid, inter alia, methyl cellulose.
- EP 425 997 discloses that hydrophobically modified alkyl- cellulose, alkylhydroxyalkylcellulose or hydroxyalkylcellu- lose can be used as thickening agent in aqueous paper coat ⁇ ing compositions.
- the hydrophobing groups are preferably C 12 _ 16 -alkyl groups or alkylaryl groups.
- a multipolysaccharide-containing suspen ⁇ sion which contains a low molecular polysaccharide, which is dissolved in the aqueous phase and which can be a car ⁇ boxymethylcellulose or a hydroxyethylcellulose.
- the coating composition contains one or more dispersed, i.e. not dissolved, cellulose polymers, such as hydroxypropyl- cellulose, methylcellulose, methylhydroxypropylcellulose and hydrophobically modified hydroxyethylcellulose.
- compositions for coating such as application of a layer of a coating slip or surface sizing, of cellulose- based products, such as paper and board, with improved properties in respect of viscosities at increased tempera ⁇ tures and at high shear rates can be obtained if use is made as thickening agent of a water-soluble, nonionic alkyl ⁇ hydroxyalkylcellulose, which contains alkyl groups having 1- 3 carbon atoms and hydroxyalkyl groups containing 2-3 carbon atoms, but which is free from hydrophobically modifying hydrocarbon groups having at least 4 carbon atoms, the cellulose ether having a cloud point in the range from 35 to 80°C, preferably from 45 to 70 C C.
- the alkylhydroxyalkyl ⁇ cellulose thus is dissolved in the composition and its vis- cosity can vary within wide ranges, such as from 5 mPa*s to 150,000 mPa»s, but usually is 10-10,000 mPa-s in 2% aqueous solution at 20°C.
- compositions that are produced while using the above- described cellulose ethers as thickening agent have a low viscosity at high shear rates and a low tendency to splash, which makes them suitable to apply on two-dimensional cellu ⁇ lose products, such as paper and board.
- the viscosity in ⁇ crease which arises in the composition when the coated cellulose product is heated during the drying stage, stabi ⁇ lises and immobilises the applied layer and facilitates the subsequent treatment.
- the inventive compositions have as good dewatering or even more rapid dewatering than compositions containing other types of cellulose ethers and not having the same viscosity increase at an increased temperature.
- Typical cellulose ethers for use in compositions ac ⁇ cording to the invention are ethylhydroxyethylcellulose, ethylethylhydroxyethylcellulose, methylethylhydroxyethyl- hydroxypropylcellulose and methylhydroxypropylcellulose.
- the hydroxyethyl groups constitute at least 30% of the total number of hydroxyalkyl groups, and the number of ethyl substituents usually constitutes at least 10% of the total number of alkyl substituents.
- the amount of alkylhydroxyalkylcellu- lose usually is from 0.05 to 3, preferably from 0.2 to 1.5% by weight of the composition.
- the cellulose ethers can be produced in conventional manner by reacting mercerised cellulose with ethylene oxide and/or propylene oxide and methylchloride, ethylchloride and/or propylchloride.
- the water-based compositions according to the inven- tion suitably contain a binder in an amount 2-70, preferably 5-30% by weight.
- the binder may consist both of water- soluble binders and of binders in the form of water dispersions or latex.
- suitable binders are copolymerisates of ethylenically unsaturated carboxylic acids, starch, proteins, casein and carboxymethylcellulose.
- compositions When the compositions are to be used for surface sizing of cellulose-based two-dimensional products, they also contain 5-65% by weight size, based on the dry solids content of the composition.
- suitable sizes are different types of colophonium, sulphate resin, protein complex, polyethylene wax dispersions, paraffin copoly ers, melamine-formaldehyde resins etc.
- a cellulose-based product coated with a composition according to the invention can be produced by a) applying a composition according to the invention at a temperature below the cloud point of the alkylhydroxyalkylcellulose to the cellulose-based product, b) drying the two-dimensional cellulose product coated with the composition during heating, and c) if desired, calendering said cellulose product.
- the application of the composition takes place in a manner known per se, for instance by air knife coating, roll coat ⁇ ing or blade coating.
- at least 90% of the drying takes place at a temperature range which to at least 60%, preferably completely, falls below the cloud temperature of the alkylhydroxyalkylcellulose.
- the temperature of the composition in application usually is in the range of 5-30, preferably 10-25°C.
- aqueous coating slip compositions with a dry solids content of 60% by weight and intended for coating of paper were produced, based on the following recipe. 100 parts by weight kaolin
- V ethylhydroxyethylcellulose, cloud point 69°C, viscosity 80,000 mPa «s
- the viscosity of the coating slip compositions according to the invention after application, increased as the temperature was increased, whereas the coating slip compositions produced according to prior-art technique presented merely insignificant viscosity increases or even considerable viscosity decreases.
- compositions accord ⁇ ing to the invention had a better development of the visco ⁇ sity when increasing the temperature than that of the com ⁇ parison compositions.
- Latex Latex, styrene-butadiene 10 10 10
- a composition in an amount of 24 g was weighed in thin-walled aluminium dishes and were levelled such that the surfaces, through which evaporation of water could take place, were of the same size.
- the various samples were then dried in a heating cabinet at 105 C C and the change in weight was measured every 15th minute.
- the evaporation of water at the time 0 was determined as the average evaporation of water during the first 15 min of heating of the composition from 25°C to the final temperature 105°C. The following results were obtained.
