【摘要】 以过硫酸铵(APS)为引发剂,吐温80(Tween-80)和OP-10为乳化剂,自制的不饱和聚酰胺多胺环氧氯丙烷树脂(PAE)、苯乙烯(St)和丙烯酸丁酯(BA)为原料,采用乳液聚合的方法制备PAE/St/BA共聚物乳液。通过傅里叶变换红外光谱(FTIR)、热重分析(TGA)、Zeta电位及粒径分析、静态接触角和扫描电镜(SEM)对乳液的结构和性能进行了表征,并研究了不饱和PAE树脂用量对乳液施胶性能的影响。结果表明,当聚合反应中不饱和PAE树脂用量为3%(以乳液质量计),乳液用量为0.6%(以施胶液质量计)时,PAE/St/BA共聚物乳液施胶效果较好。更多还原

【Abstract】 PAE /St /BA copolymer emulsion has been prepared from unsaturated PAE resin,styrene and butyl acrylate by means of emulsion polymerization in the presence of ammonium persulfate as initiator, and Tween- 80 and OP- 10 as emulsifier. The structure and property of the copolymer were studied by FTIR,TGA,Zeta potential measurement and particle size analyzer,static contact angle and SEM. The effect of the dosage of unsaturated PAE resin on the property of the copolymer was discussed in the paper. The results show that the excellent performance and good sizing effects of PAE / St / BA copolymer emulsion were achieved when the reaction conditions were as follows: the dosage of unsaturated PAE resin was 3% in polymerization and the dosage of the surface sizing agent was 0. 6%.更多还原
