摘　　要：在氮气保护下,将含双端含氢硅油、侧链氢聚硅氧烷与多种烯丙基聚醚化合物在铂催化剂作用下,进行一锅法加成聚合反应制得,具有操作工艺简单、适合大规模生产。该有机硅流平剂在水性涂料应用性能测试表明,其在流平性、相容性、重涂性和耐冷热性等综合性能方面表现出色。Under the protection of nitrogen, it is prepared by one-pot addition polymerization of double-ended hydrogen-containing silicone oil, side-chain hydrogen polysiloxane and various allyl polyether compounds under the action of platinum catalyst, which has a simple operation process., suitable for mass production. The performance test of the silicone leveling agent in water-based coatings shows that it has excellent comprehensive properties such as leveling,compatibility, recoatability and heat and cold resistance.
