蓬松型聚醚嵌段硅油的制备及应用性能研究

Synthesis and Application of Polyethre Block fluffy Silicone Oil

以氯铂酸催化剂,利用端含氢硅油、烯丙基环氧聚醚合成端环氧聚醚硅油,然后加入聚醚胺和溶剂在80~83℃下反应制得蓬松型聚醚嵌段硅油;考察了合成过程中各种因素,结果表明:选用国内品质较好的D4作为原料合成端含氢硅油,然后和烯丙基环氧聚醚法合成分子量为13000的端环氧聚醚硅油,选用组合聚醚胺ED900+T403,两者的摩尔比为1:1.35,以乙二醇单丁醚为溶剂,反应时间控制在8-10小时合成蓬松型聚醚嵌段硅油,乳化比例控制在1:15~1:12能,然后得到蓬松风格的聚醚嵌段硅油HT-6058。该产品表现出优越的蓬松感、滑度及回弹效果,优越的耐酸、耐盐和耐温性能,并且能与其他各种助剂稳定配伍,为我客户使用提供了便利。

The epoxide-terminated polyether silicone was synthesized by the side hydrogen silicone oil and the polyalkyl glycol epoxyl ethers under the condition of platinum chloride as catalyst,and the Fluffy silicone oil was reaction with polyetheramine,solvent and epoxide-terminated polyether silicone in 80 ～ 83℃.Study synthesis of various factors,the results showed that：D4 is used as the syntheticmaterial of the side hydrogen silicone oil,the synthesis of epoxide-terminated polyether silicone by alkali method and the molecular weight control was 13000,Selected solvent for ethylene glycol monobutyl ether,Selected polyetheramine for ED900＋T403,Reaction time was controlled at 8-10 hours,Can be synthesized with a fluffy style of polyether block silicone oil HT-6058.
