摘要
采用正交设计实验法以二甲基硅油及聚醚为主要原料制备了一种新型改性有机硅消泡剂。通过消泡实验及稳定性实验确定了该消泡剂的制备工艺:硅油质量分数为86％,聚醚9％,催化剂0．1％;反应温度为200℃,反应时间为2 h;采用HLB值为9左右的复合乳化剂可得到稳定的高效消泡剂。
Modified organo-silicon defoamer was obtained with dimethyl-silicon oil and polyther through test oforthogonal design. Through analyzing the actors of reaction time and reaction temperature, the optimum conditions had been confirmed as silicon oil mass fraction 86%, polyther mass fraction 9%, catalyst 0,1%, reaction temperature 200℃, reaction time 2 h, value of HLB 9.
