Abstract
The composite building coating of polyvinyl alcohol, bentonite and the like can improve the cohesiveness, the covering power, the film forming property, the stability and the brushing property of the coating, can reduce the consumption of base materials and pigments in the traditional coating (106 coating), reduces the cost from 350 plus one 450 yuan per ton to 200-250 yuan per ton, is suitable for interior wall coatings of hospitals, shops, office buildings and civil buildings, and has remarkable economic benefit.
Description
The invention belongs to the architectural decoration paint field, can be used for the interior wall coating of hospital, shop, office building and covil construction.
Along with developing rapidly of China's construction work, the building decoration engineering specification of quality is also more and more higher.At present, extensively having adopted polyvinyl alcohol is base-material, adds a certain amount of filler, pigment and auxiliary agent and makes various building coatings through grinding.The coating made of polyvinyl alcohol and borax reaction is wherein arranged, can only be with the spraying of machine secondary, efficient height but complex process, internally wall base face and humidity have requirement.It is the coating that base-material is made that polyvinyl alcohol and formaldehyde reaction generate polyvinyl alcohol hemiacetal glue, and it is many to contain free formaldehyde content, and the strong impulse smell is arranged, and human body is had harm, and construction is extremely inconvenient, suddenly waits to improve.Polyvinyl alcohol and water glass are the coating (being called for short 106 coating) that base-material is made, and Qu Limeng etc. (Building technology 1983, NO.928-30) report to some extent.This interior wall coating belongs to the low gear product, and price is at 500-550 unit/ton, because starting material are constantly raised the price, polyvinyl alcohol is mentioned 4500 yuan/ton by 3300 yuan/ton, and the titanium dioxide price is to 8000 yuan/ton, and zinc sulfide white is 1700 yuan/ton.Because the cost of 106 interior wall coatings improves constantly, profit descends, and influences the expansion production of this coating.
The objective of the invention is deficiency, 106 coating are improved at above-mentioned building coating.It is abundant to have introduced China storage in 106 coating, exploitation easily, and the cheaper wilkinite of price general charged is as filler.A kind of tonstein, the montmorillonite that wilkinite is made up of the montmorillonoid thing is a kind ofly to have expansion character to be the hydrous alumino silicates that laminate structure contains small amount of alkali and alkaline-earth metal, has water swelling, dispersiveness, suspension, thixotropy and lubricity.It is used in the interior wall coating, can increases cohesiveness, stability, film-forming properties and the brushing property of coating.With the compounded coating of polyvinyl alcohol, can improve the sticking power and the opacifying power of filming.And can reduce the consumption of base-material in 106 coating (polyvinyl alcohol) and pigment (titanium dioxide and zinc sulfide white), and so not only improve the performance of coating, can also reduce the cost of coating significantly.
A kind of polyvinyl alcohol that provides of the present invention is a base-material, contains filler and auxiliary agent, the building coating of making through grinding, and in coating, introduce its recipe ingredient of wilkinite (by weight) and be:
1, base material formulation

The preparation method of composite coating such as polyvinyl alcohol and wilkinite
1. the preparation of base-material:
By above-mentioned prescription the part tap water is added in the enamel still of 1000 liters that have agitator and heating or cooling jacket, start stirring motor, respectively polyvinyl alcohol and urea are added in the still slowly, in chuck, send steam heating, again the pre-heated tap water of surplus is added in the still, below 98 ℃, kept about 0.5 hour in the still temperature, polyvinyl alcohol all dissolves (blowing is observed no saccharoid), and it is standby that base-material is put into storage tank.
2. the preparation of coating:
By above-mentioned prescription the base-material in the storage tank is filtered metering, squeeze in the batch mixing still that has agitator with pump, 2/3rds of the water component in still in the adding coating, start stirring motor, slowly add the solution after 1/3rd and water glass of water component dilutes in the coating, continue to stir after 20～30 minutes, add sodium bentonite successively by above-mentioned prescription metering again, ultramarine, talcum powder, light calcium carbonate, zinc sulfide white, sodium hexametaphosphate solution carboxymethyl cellulose aqueous solution and tributyl phosphate etc., continue to stir after 10～15 minutes, treat that various mixing of materials are even, send into sand mill and carry out the normal temperature grinding, about 0.5 hour of milling time, after fineness reaches 40～90 μ m, send into storagetank, packing is sold after filtration.Prepare Color paint as need, in the batch mixing still, add mill base and get final product.
3. coating property index:
