摘　　要：采用特殊处理的硅树脂和高浊点聚醚,对自制有机硅消泡剂确定合成路线及制备工艺条件,合成硅聚醚接枝特殊改性聚硅氧烷类的自乳化耐高温消泡剂3060,通过与国外的同类产品进行性能对比实验,并进行定性的粒径分析,对消泡剂的制成和消泡机制进行分析研究。结果表明:自乳化耐高温消泡剂3060消泡和抑泡效果好,粒径小、稳定性良好,因此在应用上可替代进口B产品消泡剂,实现耐温消泡剂国产化,有效降低成本。Synthesizing polyether modified siloxane antifoam 3060 which self-emulsified and anti- high temperature by using the special treated silicone resin and high cloud point polyether, and designning the synthesis route and production condition. Based on the comparing antifoam performance and analysed partical size of the imported antifoam and 3060, study antifoam production and antifoam mechanism. It is proved that the antifoam 3060 has good stability, antifoam and defoam performance and smaller partical size. So that 3060 can replace imported antifoam B and reducing the cost, and realizing local production
