| titleOfInvention | A kind of continuous production process of siloxane polymer |
| abstract | The invention provides a continuous production process for siloxane polymers, which can produce siloxane polymers with different functional groups. Firstly, the siloxane raw material is added to the liquid acid catalyst and the end-capping agent at 60-110°C, and the reaction time is 3-5h. Secondly, the semi-finished product is subjected to alkali washing, water washing, devolatilization and other steps to obtain colorless and transparent siloxane polymerization. thing. The siloxane raw material can be hexamethylcyclotrisiloxane D3, octamethylcyclotetrasiloxane D4, decamethylcyclopentasiloxane D5, siloxane hydrolysis mixture, linear polymethylsiloxane, RTV silicone rubber (107 glue). The invention uses a low-cost, high-catalytically active liquid acid catalyst to produce the siloxane polymer, has mild reaction conditions, simple operation and low cost, and is suitable for large-scale production. The used catalyst avoids the problem that the solid catalyst produces hazardous solid waste, and the product can meet the emission standard after being neutralized by alkali and washed with water. |
