摘要
以苯乙烯(St)、丙烯酸丁酯(BA)、甲基丙烯酸甲酯(MMA)、丙烯酸(AA)、丙烯酸羟乙酯(HEA)为原料,通过乳液聚合法合成固含量约为40%的轻度交联苯丙胶乳纸张涂布剂。考察了不同单体用量对乳胶膜机械性能的影响。结果表明,当m(MMA)=11.5%,m(AA)=6.9%,m(HEA)=11.5%,m(St)/m(BA)=1∶2时,乳胶膜呈现良好的机械性能,乳液粒子尺寸较小且分布窄,平均粒径为128.9nm;且聚合物具有良好的耐热性。
Self-crosslinking styrene-acrylic emulsion coating agent for paper was prepared by emulsion polymerization with styrene(St),butyl acrylate(BA),methyl methacrylate(MMA),acrylic acid(AA),hydroxyethyl acrylate(HEA) as raw materials,and the solid content of the emulsion was up to 40%.Effects of monomers concentration on the mechanical properties of film were investigated.It was found that the emulsion film was endowed with excellent mechanical property and thermal stability when m(MMA)=11.5%,m(AA)=6.9%,m(HEA)=11.5% and m(St)/m(BA)=1∶2.And the average particle size of the emulsion was 128.9nm with narrow particle size distribution.
