摘要
研究了将高、低沸点甲基氯硅烷生产废液分别通过醇解和水解反应制备HCl和有机硅树脂的工艺方法,考察了醇解时间、醇解温度和m(废液)∶m(甲醇)等因素对产物收率的影响。实验得到最佳反应条件为:m(废液)∶m(甲醇)=1∶0.5,醇解温度65℃,醇解时间2 h。在该条件下由高、低沸点废液制得的有机硅树脂收率分别为43.2%和40.6%。将制得的有机硅树脂经500℃干燥处理后,可作为填料,制备有机硅树脂-聚氯乙烯复合材料。该材料的力学性能与SiO2-聚氯乙烯复合材料接近。
The preparation of hydrogen chloride and silicon resin by hydrolysis or alcoholysis reaction were studied using high/low-boiling point waste liquid in methyl chlorosilane production as raw materials. The factors affecting the product yield were investigated. The optimum reaction conditions are as follows： m（ waste liquid） ： re（methanol） = 1 ： 0.5, alcoholysis temperature 65 ℃, alcoholysis time 2 h. Under these conditions, the yields of silicon resin prepared from high/low-boiling point waste liquid are 43.2% and 40.6% respectively. After the silicon resin is dried at 500 ℃, it can be used as filler to prepare silicone-polyvinyl chloride composite. The mechanical properties of the composite are close to those of SiO2-polyvinyl chloride composite.
