摘要
合成了含有缩水甘油基、羧基和胺基的多层核壳型室温自交联乳液 ,研究了聚合温度、乳化剂用量和加料速率对所得乳液性能及其涂膜性能的影响。研究表明 ,聚合温度升高使乳胶膜的交联密度降低 ,而涂膜耐水性和乳液贮存稳定性在 5 0℃呈现最佳值。在乳化剂含量为 2 %时 ,涂膜的交联密度最大且耐水性最佳 ,而乳液的贮存稳定性随乳化剂用量的增加而增大。加大乳化单体滴加速率 ,乳液贮存稳定性降低 ,乳胶膜的交联密度增大。
The latex crosslinkable at ambient temperature containing glycidyl group, carboxyl group and amino group was synthesized. The effect of the polymerization temperature, emulsifier content, and the feed rate of the emulsified monomers on the properties of the latex and the film properties from it were investigated. The results indicate that the crosslinking density of the film decreases at higher polymerization temperature. The anti water of the film and the shelf life of the latex is the best when the polymerization temperature was at 50?℃. The shelf life of the latex have been improved by increasing the content of the emulsifier. The best anti water and the biggest crosslinking of the films have been obtained when using 2% emulsifier content. The shelf life of the latex has been increased and the crosslinking density of the film was the bigger when the emulsified monomers was fed at higher rate.
