Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of interiro wall latex paint putty paste not adding formaldehyde, safety and environmental protection is provided.
The technical solution used in the present invention is as follows:
A kind of Formaldehyde-free putty paste for interior wall latex paint, is made up of the raw material of following weight part: dry powder 30-50, modified talc powder 40-60, terra alba 5-10, polyvinyl alcohol 2-3, carboxymethyl cellulose 2-3, carboxymethyl starch ether 0.5-1, sodium abietate 0.5-1, water 35-45;
The preparation method of described modified talc powder is as follows: take talcum powder by weight 4-8:2-3:1-2:1, wilkinite, jade powder, boron mud mixes, add the trolamine of 1-2%, the sodium polyacrylate of 2-3%, the calcium lignin sulphonate of 1-2%, vinyl three ('beta '-methoxy oxyethyl group) silane of 0.5-1%, 2000-3000rpm speed lapping 10-15min, dry, pulverize, cross 400-500 mesh sieve, then add appropriate water making beating and make the slurries that concentration is 40-50%, add the Sodium dodecylbenzene sulfonate of 2-3%, the polyvinylpyrrolidone of 3-5%, the organosilicon crylic acid latex of 4-8%, the butyl of 0.5-1%, the Lauryl Alcohol ester of 1-2%, stir 1-2h, filter, dry, pulverize porphyrize, cross 300-400 mesh sieve.
Preferably, a kind of Formaldehyde-free putty paste for interior wall latex paint, is made up of the raw material of following weight part: dry powder 40, modified talc powder 40, terra alba 10, polyvinyl alcohol 3, carboxymethyl cellulose 2, carboxymethyl starch ether 0.5, sodium abietate 0.5, water 35;
The preparation method of described modified talc powder is as follows: take talcum powder by weight 6:3:2:1, wilkinite, jade powder, boron mud mixes, add the trolamine of 1.5%, the sodium polyacrylate of 2%, the calcium lignin sulphonate of 1%, vinyl three ('beta '-methoxy oxyethyl group) silane of 0.8%, 2000rpm speed lapping 15min, dry, pulverize, cross 400 mesh sieves, then add appropriate water making beating and make the slurries that concentration is 45%, add the Sodium dodecylbenzene sulfonate of 2%, the polyvinylpyrrolidone of 4%, the organosilicon crylic acid latex of 5%, the butyl of 0.6%, the Lauryl Alcohol ester of 1.5%, stir 1.5h, filter, dry, pulverize porphyrize, cross 400 mesh sieves.
Preparation method: above-mentioned raw materials is added high-altitude mixing and blending machine and stir 25-40 minute, packing, gets product.
Beneficial effect of the present invention:
Modified talc powder of the present invention has had anticorrosive mildewproof performance, and without the need to adding harmful sanitass such as formaldehyde again, obtained putty paste is not only harmless, safety and environmental protection, can also purify the air of a room, and keeps HUMAN HEALTH.Putty paste of the present invention also has water-tolerant, short, easy polishing curing cycle and and the feature such as the compatibility of emulsion paint is good.
