摘　　要：揭示了高固体丙烯酸树脂分子量大小受α-甲基苯乙烯二聚体的影响规律。用六亚甲基二异氰酸酯三聚体和丙烯酸树脂进行交联固化反应,制备了交联固化涂膜,并对树脂及其交联固化涂膜的机械性能进行表征。结果表明:α-甲基苯乙烯二聚体对降低丙烯酸树脂黏度和分子量有积极影响,在高固体分羟基丙烯酸树脂合成中的用量应为0.5%~1.5%。The law that the molecular weight size of high solid acrylic resins is influenced by α-methylstyrene dimer is revealed.The cross-linking curing reaction was carried out with hexamethylene diisocyanate trimer and acrylic resin,and the cross-linking cured coating film was prepared,and the mechanical properties of the resin and its cross-linking cured coating film were characterized.The results showed that α-methylstyrene dimer had a positive effect on reducing the viscosity and molecular weight of the acrylic resin,and the dosage in the synthesis of high solid hydroxyacrylic resin should be 0.5%~1.5%.
