硅油制备

1.将聚甲基硅氧烷和气相二氧化硅混合辊碾成硅脂，再加入聚氧乙烯醇、吐温80及去离子水等乳化而成。

2.以二甲基二氯硅烷、水、溶剂为原料，经水解、中和、分馏得到八甲基环四硅氧烷。八甲基环四硅氧烷在催化剂作用下经聚合反应制得。

3.主要有酸平衡法和碱平衡法两种。酸平衡法适合于生产运动黏度在500mm²/s以下的低黏度硅油，该法一般采用浓硫酸作催化剂，在50～50℃反应，然后水洗除酸、脱低沸物、加活性炭脱色、过滤得成品。而碱平衡法则适合于生产运动黏度在100mm²/s以上的中、高黏度硅油。

还可以用二甲基混合环体和十甲基四硅氧烷为原料、四甲基氢氧化铵为催化剂，在90～120℃间采用程序控温的办法，合成出甲基硅油。可将转化率由平均65%提高到80%以上。
