摘要
制备了低交联度的核壳型丙烯酸聚氨酯乳液.采用双酚A型环氧树脂(E-44)和三羟甲基丙烷三(3-丙烯亚胺)丙酸酯(TMPTA-MAZ)作为乳液的固化剂,研究了核壳型丙烯酸聚氨酯乳液的固化与涂膜性能.研究表明:E-44和TMPTA-MAZ均可作为核壳型丙烯酸聚氨酯乳液的固化剂.两种不同类型的固化剂均能使乳液室温成膜,涂膜均一透明.TMPTA-MAZ比E-44更适合作为核壳型丙烯酸聚氨酯乳液的固化剂.当加入适量的固化剂时,涂膜的耐水、耐溶剂性以及力学性能都有很大程度的提高.
The low degree of crosslinking acrylic polyurethane core-shell emulsion was prepared. Studies were focus on the curing process and coating performance of the coreshell emulsion by using bisphenol A epoxy resin （E-44） and trimethylolpropane tri（3- propylene imine） propionate （TMPTA-MAZ） as curing agents respectively. The results showed that E-44 and TMPTA-MAZ both can be used as curing agents for the core-shell emulsion. They can cure the emulsion to transparent film at room temperature. Moreo- ver, as a curing agent, TMPTA MAZ was more suitable than E-44. When adding proper amount of curing agents, the coating properties such as water resistantance, solvent-resistance and mechanical properties was to a large extent improved.
