二甲基硅油及其衍生物在消泡剂领域的研究进展

Development of dimethyl silicone oil and its derivatives in defoamer field

二甲基硅油由于其良好的化学惰性和低表面张力,广泛应用于消泡剂领域。聚醚改性硅油和氟改性硅油作为二甲基硅油的两种主要衍生产物,具有更强的消、抑泡能力。本论文重点介绍了二甲基硅油消泡剂、聚醚改性硅油消泡剂、氟改性硅油消泡剂的特性、制备方法及应用。

DimethyI silicone oil, with excellent chemicai inertness and low surface tension, was widely used as the raw material of defoamer agent. Polyether modified silicone and organic fluorine modified silicone are the two major silicone modifiers, with more excellent defoaming and antifoaming activities. This paper summarized the performance, preparation and applications of dimethyl silicone oil based defoamer, polyether modified silicone oil-based defoamer and organic fluorine modified silicone oil-based defoamer.
