[0002] Architectural coatings modified solely with bentonite, architectural coatings modified solely with polyvinyl alcohol, and architectural coatings modified with bentonite and polyvinyl alcohol have already appeared and been used in the field of construction at home and abroad, but these types of coatings are unevenly painted. , there are traces of brushing, the surface is rough, the hand feels bad, the durability is poor, it is easy to peel, and it cannot achieve the same effect as acrylic latex paint
The interior wall architectural coatings made of acrylic emulsion also have fatal weaknesses. For example, the content of organic matter and harmful volatiles is high, which pollutes the environment, and the surface is rough and not smooth, which affects the feel.
In addition, due to the need to add preservatives, it will affect people's health

example 1
[0017] Raw material formula: modified bentonite slurry 50kg, modified polyvinyl alcohol glue 15kg, slaked lime slurry 15kg, titanium dioxide 5kg, talc powder 5kg, defoamer 0.01kg, dispersant 0.1kg, film-forming aid 0.39kg , 9.5kg of water. The sum of the mass of each component is 100%.
[0018] Preparation:
[0019] Mix the modified bentonite slurry with the modified polyvinyl alcohol glue, stir at high speed for 15 minutes, then add the slaked lime slurry and stir for 15 minutes until uniform, then add titanium dioxide, talcum powder, defoamer, dispersant, and film-forming aid in sequence Mix with water, stir at a low speed for 30 minutes, and then put the paint into a sand mill to grind it twice, filter it with a 300-mesh sieve, and pack it into a barrel.
example 2
[0021] Raw material formula: 20kg of modified bentonite slurry, 25kg of modified polyvinyl alcohol glue, 25kg of slaked lime slurry, 10kg of titanium dioxide, 10kg of talc powder, 0.02kg of defoamer, 0.3kg of dispersant, and 0.68kg of film-forming aid , water 9kg.
[0022] The preparation method is the same as in Example 1.
example 3
[0024] Raw material formula: 40kg of modified bentonite slurry, 18kg of modified polyvinyl alcohol glue, 20kg of slaked lime slurry, 8kg of titanium dioxide, 6kg of talc powder, 0.01kg of defoamer, 0.29kg of dispersant, and 0.7kg of film-forming aid , 7kg of water.
[0025] The preparation method is the same as in Example 1.

Abstract
The invention belongs to the field of building coatings and discloses a double modified composite interior wall building coating; the double modified composite interior wall building coating comprises the following components by weight percent: 20 percent to 50 percent of modified bentonite slurry, 15 percent to 25 percent of modified polyvinyl alcohol gluewater, 15 percent to 25 percent of whitelime slurry, 5 percent to 10 percent of titanium dioxide, 5 percent to 10 percent of talcum powder, 0.01 percent to 0.02 percent of foam killer (tributyl phosphate), 0.1 percent to 0.4 percent of TFC-1 dispersant, 0.3 percent to 0.7 percent of propanediol film-forming additive, and 5 percent to 12 percent of water. The coating has the advantages of even brushing, no roller brushing track, smooth surface, good levelability, good feel to touch, good film forming effect, no preservative, no toxicity, no harm, no deposition and no powder falling off; all properties can meet the technical requirements for interior wall building coatings; therefore, the coating is the best substitute of the prior latex paint interior wall building coatings.
