    • PURPOSE: A non-pollutant coating composition is provided, to allow it to be dried naturally and to improve the coating properties and the paint storage stability by employing a hydrophilicity imparting agent containing a SiOH group and a hydrolysis accelerator. CONSTITUTION: The non-pollutant coating composition comprises 20-60 wt% of an acrylpolyol resin; 5-20 wt% of a curing agent; 5-15 wt% of a hydrophilicity imparting agent; 0.6-4 wt% of a hydrolysis accelerator; 10-40 wt% of a pigment; 0.001-0.01 wt% of a curing catalyst; 10-30 wt% of a solvent; and 5-20 wt% of a diluting agent. Preferably the acrylpolyol resin has a mean number molecular weight of 4,000-15,000, a hydroxy number of 80-200 mg KOH/g and a glass transition temperature of 30-55 deg.C; the curing agent is diisocyanate or isophorone diisocyanate; and the hydrophilicity imparting agent is at least one selected from the group consisting of a polymer of methyl silicate and ethyl silicate, a tetraalkoxysilane compound and a polyether modified silicone oil and is represented by the formula 3, wherein R is methyl group or ethyl group; and the hydrolysis accelerator is a metal chelate compound.
    • 目的:提供一种无污染的涂料组合物,通过使用含有SiOH基和水解促进剂的亲水性赋予剂,使其自然干燥并改善涂料性能和油漆保存稳定性。 构成:无污染涂料组合物包含20-60重量%的丙烯酸多元醇树脂; 5-20重量%的固化剂; 5-15重量%的亲水性赋予剂; 0.6-4重量%的水解促进剂; 10-40重量%的颜料; 0.001-0.01重量%的固化催化剂; 10-30重量%的溶剂; 和5-20重量%的稀释剂。 优选地,丙烯酸多元醇树脂的平均数分子量为4,000-15,000,羟值为80-200mg KOH / g,玻璃化转变温度为30-55℃; 固化剂是二异氰酸酯或异佛尔酮二异氰酸酯; 亲水性赋予剂为选自甲基硅酸酯和硅酸乙酯的聚合物,四烷氧基硅烷化合物和聚醚改性硅油中的至少一种,由式3表示,其中R为甲基或乙基; 水解促进剂为金属螯合物。
