摘要
研究了乳化剂配比、缓冲剂加入方式、玻璃化温度(Tg)、聚合工艺对乳液性能的影响.结果表明:采用非离子型乳化剂较多的复合乳化剂配比和缓冲剂在反应前一次性加入的方式有利于提高丙烯酸酯乳液的稳定性,从而获得符合要求的乳液;聚合物体系的Tg、聚合工艺对乳液性能影响较大,采用软壳硬核的聚合工艺设计可大大降低最低成膜温度(MFT).
The effects of the proportion of emulsifier, the feeding mode of buffer agent, the glass transition temperature(Tg) on the properties of acrylic emulsion were studied. The results show that the stability of acrylic emulsion is increased by using more nonionic emulsifier and feeding the buffer agent before polymerization wholly. The required emulsion can be obtained in this way. The properties of acrylic emulsion are deeply affected by glass transition temperature and polymerizing technology and the lowest-filming temperature is decreased greatly by using the polymeric design of soft-shell and hard-core.
