| 摘 要： | 采用甲基丙烯酸甲酯、丙烯酸丁酯和丙烯酸为反应单体,以N-羟甲基丙烯酰胺(NMA)为功能单体,通过预乳化半连续种子乳液聚合工艺制备了NMA改性核壳型丙烯酸酯乳液,讨论了NMA用量对乳液的凝胶率及离心稳定性和贮存稳定性的影响,并对乳胶膜的吸水性、力学性能及耐热性进行了表征。结果表明:当NMA的用量为1.5%(wt)时,乳液的凝胶率仅为0.23%(wt),具有良好的离心稳定性和贮存稳定性,乳胶膜的吸水性由6.0%(wt)下降至4.5%(wt),铅笔硬度和冲击强度分别由1 H和52 cm提高至2 H和55 cm以上,弯曲强度、附着力及耐热性俱佳。

| Abstract: | N-methylol acrylamide(NMA)modified acrylates emulsions with core-shell structure were prepared with methyl methacrylate,butyl acrylate and acrylic acid as reactive monomers and NMA as functional monomer by pre-emulsification semi-continuous seed emulsion polymerization.The effect of the amount of NMA on the gel ratio,centrifugation stability and storage stability was studied,and the water absorption,mechanical properties and heat resistance of latex films were characterized.The results showed that when the ... |
