摘要
通过5种不同方法制备支链化的氨基硅油:(1)以氨乙基氨丙基三甲氧基硅烷为硅烷偶联剂和羟基封端聚二甲基硅氧烷反应制得P1;(2)以氨乙基氨丙基甲基二甲氧基硅烷、甲基三甲氧基硅烷和羟基封端聚二甲基硅氧烷反应制得P2;(3)首先用甲基三甲氧基硅烷和氨乙基氨丙基甲基二甲氧基硅烷制得含有氨基的硅树脂I1,然后通过硅树脂与羟基封端聚二甲基硅氧烷的平衡反应制得P3;(4)首先制备乙烯基二甲基硅醇,然后将其与六甲基环三硅氧烷反应得到单端硅羟基聚硅氧烷,再与氨乙基氨丙基三甲氧基硅烷反应得到硅烷中间体I2,I2与羟基封端聚二甲基硅氧烷反应得到P4;(5)同方法(4)得到相同的单端羟基硅氧烷,再与甲基三甲氧基硅烷反应得到中间体I3,I3与氨乙基氨丙基甲基二甲氧基硅烷和羟基封端聚二甲基硅氧烷反应,得到P5。通过非离子乳化剂得到粒径一致的硅油乳液,并以其对涤纶织物进行手感整理,结果表明:使用P4和P5所制备的乳液具有优异的柔软整理效果,在软度和松度方面均具有非常好的表现。
The branched amino silicone oil was prepared by the following five methods:1)P1 was prepared by reacting aminoethylaminopropyl trimethoxysilane as silane coupling agent and hydroxyl terminated polydimethylsiloxane;2)P2 was prepared by reacting aminoethyl aminopropyl methyldimethoxysilane,methyltrimethoxysilane,and hydroxyl terminated polydimethylsiloxane;3)methyltrimethoxysilane and aminoethylaminopropylmethyldimethoxysilane were used to prepare amino silicone resin I1;then P3 was prepared by the equilibrium reaction between silicone resin and hydroxyl terminated polydimethylsiloxane;4)Firstly,vinyldimethylsiloxane was prepared,and then it reacted with hexamethylcyclotrisiloxane to obtain single terminated silylhydroxy polysiloxane,which would reacted with aminoethyl aminopropyl trimethoxysilane to obtain silane intermediate I2.Finally,I2 reacted with hydroxy terminated polydimethylsiloxane to obtain P4;5)The single-ended hydroxyl siloxane was obtained as step 4,and then reacted with methyl trimethoxysilane to obtain an intermediate I3,which reacted with aminoethyl aminopropyl methyl dimethoxysilane and hydroxyl-terminated polydimethylsiloxane to obtain P5.The silicone oil emulsions with the same particle size were obtained by nonionic emulsifier,and were used to finish polyester fabrics.The results show that the emulsions prepared with P4 and P5 have excellent softening finishing,and have good performance in softness and looseness.
