【摘要】 采用超声波处理为分散手段,通过自乳化法制备了改性氯化聚丙烯(CPP)乳液。比较了机械搅拌和超声乳化工艺对制备CPP乳液性能的影响;研究了超声波作用时间、作用功率对乳液性能的影响以及对乳液粒径及其分布的影响,结果表明,超声波的作用功率为400 W,作用时间为6 min时,得到的CPP乳液具有良好的稳定性,而且乳液涂膜在PP塑料上的附着力达到0级。更多还原

【Abstract】 Modified chlorinated polypropylene emulsions were prepared using self-emulsified method through an ultrasonic aided dispersing process.The effect of ultrasonic and mechanical dispersing processes on CPP emulsion performance was compared.The influence of time and power of ultrasonic on properties and particle size and distribntion of modified CPP emulsion was investigated.The modified CPP emulsion showed a good stability when ultrasonic power 400 W,treatment time 6 min.The adhesion on polypropylene reached grade 0.更多还原
