In order to manufacture high performance styrene-acrylic ester emulsion,the effects of emulsifier,auxiliary agent DZ-1 and acrylic on its viscosity and thixotropy were studied in this paper.
为了制备高性能的苯丙乳液,研究了乳化剂、助剂DZ-1及丙烯酸对苯丙乳液黏度及触变指数等性能的影响。
The results show that the viscosity and the thixotropy are higher when content of emulsifier is 1.
0 %时合成的苯丙乳液粘度和触变指数较
Elastic deformation occurs at stress below the yield stress, the viscous flow appears after yield with thixotropy.
验证了在剪切应力低于屈服应力时 ,变形基本上是弹性的 ,而屈服后粘流过程显示了触变特性 。
