Waterproof agent and preparation method thereof
The invention relates to a waterproof agent and a preparation method thereof, and the waterproof agent comprises the following components in parts by mass: 45-50 parts of dimethyl tetrachlorodisilane, 30-35 parts of trimethyl trichlorodisilane, and 2-3 parts of tetramethyl dichlorodisilane. The method comprises the following steps: filtering a byproduct low-boiling-point substance generated in the synthesis process of an organic silicon monomer through a filter, inputting the filtered byproduct low-boiling-point substance into a plate type distillation tower, separating the byproduct low-boiling-point substance into a crackable low-boiling-point substance and a non-crackable substance in the plate type distillation tower, collecting the crackable low-boiling-point substance, mixing the crackable low-boiling-point substance with hydrogen, heating, carrying out cracking and disproportionation reaction, and cooling the obtained product to room temperature, and a product is separated after rectification. As a byproduct, the low-boiling-point substance is low in raw material cost, and the method has positive significance in turning the byproduct into wealth.
本发明涉及一种防水剂及其制备方法，以质量份数计，其组分包括二甲基四氯二硅烷45‑50份、三甲基三氯二硅烷30‑35份、四甲基二氯二硅烷2‑3份。将有机硅单体合成过程中产生的副产品低沸物，经过滤器过滤后输入板式蒸馏塔中，在板式蒸馏塔中被分离为可裂解低沸物和不可裂解物，收集可裂解低沸物，可裂解低沸物与氢气混合后加热，进行裂解、歧化反应，获得的产物冷却至室温，精馏后分离出产品。低沸物作为一种副产品，原料成本低，本发明将副产品变废为宝具有积极的意义。
