STUDIES ON THE MECHANISM OF so-LAR SPECTRUM SELECTIVE ABSORP-TION OF COATING FILMS-1STUDY OF NEW BINDERS FOR LIGHT-ABSORPTING COATINGS

本文对带有羟基的丙烯酸树脂改性硅聚合物，通过选择适当的实验条件使其接枝共聚，并将其作为采光涂料基料。改性基料与颜料匹配性良好，光学等性能优异，其红外辐射率较未改性的硅聚合物有较大幅度的降低。

he article has investigated the graft copolymeriza-tion of hydroxylated polyacrylate modified siliconeresins and their application as binders for light-ab-sorpting coatings. Experimentally, these bindersshowed good compatibilities with pigments and ex-cellent optical performances with much lower in-frared radiance than the unmodified.
