[0002] Vinyl silicone oil is an organic silicon compound with excellent physical and chemical properties. It has the advantages of high temperature stability, low temperature flexibility, and water resistance.

During production, the treated silane and hydrocarbon are put into the reactor, and the corresponding amount of acid or base catalyst is added. It is heated to a certain temperature and reacted to obtain vinyl silicone oil.

[0003] However, the current production method relies on the reactor to provide the environment and the raw materials themselves to react under the catalysis of the catalyst. The reaction speed is slow and takes several hours to several days, which limits the production efficiency and prevents sufficient contact between the raw material particles. Utility Model Content
