摘 要: | 以含氢硅油、(α-烯丙氧基,ω-羟基)聚氧乙烯聚氧丙烯醚(F-6)和(α-烯丙氧基,ω-甲氧基)聚氧乙烯聚氧丙烯醚(AEPM-1500)为原料,在氯铂酸催化剂作用下,通过硅氢加成反应,合成了一种聚醚改性硅油(AAMS),并用红外光谱和核磁共振氢谱对其结构进行了表征。考察了反应时间、温度以及催化剂用量对Si—H转化率的影响,较佳合成工艺为:反应时间为6h、反应温度为105℃,氯铂酸用量为20μg/g,此时,Si—H的转化率可达94.6%;随着F-6与AEPM-1500的量之比的增大,产物AAMS水溶液的表面张力先降后升,浊点升高;当F-6与AEPM-1500量之比为4:1时,AAMS水溶液的表面张力可降至28.6mN/m,浊点为24℃。

Abstract: | A allyl polyoxyethylene polyoxypropylene ether modified siloxane (AAMS) was prepared with polyhydridosilicone oil, allyl alcohol polyether and allyl-polyoxyethylene polyoxypropylene methyl ether as the starting materials in the presence of catalyst. The chemical structure of the synthesized product was charaCterized by infrared (IR) spectrum and nuclear magnetic resonance (^1 H NMR) spectrum. The effect factors, such as reaction time, temperature and amount of catalyst on Si-H conversion were investigated. The optimal preparation conditions were identified as follows: a reaction time of 6 h at 105 ℃ with a chloroplatinic-acid concentration of of 20 μg · g^-1 Under the above conditions, the Si-H conversion of 94. 6% is achived. Test results demonstrate that with increasing the mass ratio of F-6 to AEPM-1500, the surface tension of AAMS solution first decreases, then increases. At a mass ratio of 4: 1, the surface tension of AAMS aqueous solution reduces to 28.6 mN/m with a cloud point of 24 ℃. |
