摘要： This invention relates to a paint composition comprising a clay-containing pigment system, a latex binder, a polysaccharide thickener, and 0.005% to 2%, based upon the weight of the pigment, of a blocking agent which serves to prevent more than 20% of the polysaccharide thickener from being adsorbed onto the clay pigment surface, whereby the paint composition exhibits improved appearance and application performance.
摘要翻译：本发明涉及一种涂料组合物，其包含含粘土的颜料体系，胶乳粘合剂，多糖增稠剂和基于颜料重量的0.005％至2％的阻断剂，其用于防止大于20％的多糖增稠剂被吸附在粘土颜料表面上，由此涂料组合物表现出改善的外观和应用性能。

摘要： Particle Size Distribution (PSD) of polymer produced from styrene, methylmethacrylate, vinyl chloride, diethylaminoethylmethacrylate and butyl methacrylate vinyl monomers is controlled above 60% with less than 0.1% latex production using tri-calcium phosphate (TCP) in combination with a thickening agent which is one or more:

(a) hydroxyethylcellulose molecule weight 300,000 to 1,000,000;
(b) hydrophobically modified hydroxyethylcellulose molecular weight 100,000 to 800,000;
(c) carboxymethylmethylcellulose, carboxymethylmethylhydroxyethylcellulose or carboxymethylmethylhydroxypropylcellulose molecular weight 20,000 to 140,000.

摘要： Hydrophobically modified polysaccharide and synthetic polymers with molecular weights of 10,000 to 300,000 serve as associative thickeners in aqueous protective coatings to (-NORTH-)eveling without adversely affecting sag or thickening efficiency. Hydrophobically modified hydroxyethylcellulose, hydroxyethylstarch, hydroxypropylguar, etc. can be degraded with hydrogen peroxide to lower the molecular weight to the desired level. A preferred polysaccharide is hydrophobically modified hydroxyethylcellulose with a weight percent hydrophobe substitution of 0.2 to 2.0. A preferred synthetic polymer is hydrophobically modified poly(vinyl alcohol) with a molecular weight of 10,000 to 50,000.

摘要翻译：疏水改性的多糖和分子量为10,000至300,000的合成聚合物在水性保护涂层中作为缔合性增稠剂用于（-NORTH-）发泡而不会不利地影响流挂或增稠效率。疏水改性的羟乙基纤维素，羟乙基淀粉，羟丙基瓜尔胶等可以用过氧化氢降解以将分子量降低到期望的水平。优选的多糖是疏水改性的羟乙基纤维素，疏水部分取代度为0.2-2.0。优选的合成聚合物是分子量为10,000至50,000的疏水改性的聚（乙烯醇）。
