摘　　要：以八甲基环四硅氧烷(D_4)、十二烷基甲基二甲氧基硅烷,γ-哌嗪基丙基甲基二甲氧基硅烷为原料,在催化剂和增深改性剂BTA作用下,通过本体聚合的方法合成氨基改性有机硅平滑剂,采用复合型乳化剂对其进行乳化,得到滑挺增深硅油816。探讨了聚合温度、聚合时间、偶联剂组分比例、改性剂BTA用量、原油和乳化剂比例对滑挺增深硅油816合成及乳化的影响。测试分析其黏度和增深效果,且应用于棉织物滑挺增深整理并与氨基硅油平滑剂815对比。结果表明,优化合成工艺为:聚合温度125~130℃、反应时间8 min、催化剂用量为D4量的0.04%、γ-哌嗪基丙基甲基二甲氧基硅烷和十二烷基甲基二甲氧基硅烷质量比1∶3、原油和乳化剂比例为3∶1;合成的滑挺增深转化率为93.3%,性能稳定、平滑剂挺括性良好;滑挺增深硅油816的平滑效果与氨基硅油平滑剂815的效果相当,且在棉织物上的增深效果更好,活性黑增深20%~30%,硫化黑增深30%~40%。By using octamethylcyclotetrasiloxane（D4）, dodecylmethyldimethoxysilane, γ-piperazinylpropylmethyldi- methoxysilane as raw materials under the action of catalyst and deepening modifier BTA, using synthesized amino modified silicone smoothing agent in the body polymerization method, then synthesized amino modified silicone smoothing agentwas emulsifiedbythe compound emulsifier,and the slippery deepening silicone 816 wasobtained. The effects of polymerization temperature, polymerization time, proportion of coupling agent component, amount of mod- ifier BTA, ratio of crude oil and emulsifier on synthesis and emulsification of slippery deepening silicone 816 were discussed, and the viscosity and deepening effect were tested and analyzed, and it was appliedin the slipperycrisp and deepening finishing of cotton fabric.And it was compared with the amino silicone oil smoothing agent 815. The results show that the synthesis process is optimized as follows： polymerization temperature is 125-130 ℃, reaction time 8 hours, catalyst dosage is 0.04% of D4, the mass ratio of γ-piperazinyl propyl methyldimethoxysilane and dodecyl methyl dimethoxysilane is 1：3, the ratio of crude oil and emulsifier is 3：1; the conversion rate slippery deepening silicone is 93.3%, and the performance is stable and the smoothing agent is good. The effect of the smoothing of slippery deepening silicone 816 is similar to that of the amino silicone oil smoothing agent 815, and the effect of the deepening on the cotton fabric is better, active black dye can deepened 20%-30%, vulcanized black deepened 30%-40%.
