Liquid silicone rubber raw materials have been requisitioned in large quantities in the 21st century. No matter what industry the liquid silicone rubber raw materials are in, they are widely used and play a vital role. Narrowing down the scope is like construction, medical treatment and light industry. If the scope is enlarged, we can talk about nationalism and national defense, just like military fighter planes flying in the sky and military tanks running on the ground. Let me introduce to you what silicone oil is used for liquid silicone rubber.

Silicone oil generally refers to linear polysiloxane products that remain liquid at room temperature. It is generally divided into two types: methyl silicone oil and modified silicone oil. The more commonly used silicone oil - methyl silicone oil, also known as ordinary silicone oil, its organic groups are all methyl, methyl silicone oil has good chemical stability, insulation, and good hydrophobicity. It is obtained by hydrolyzing dimethyl dichlorosilane with water to obtain the initial polycondensation ring body, and the ring body is cracked and rectified to obtain the lower ring body. Generally, the silicone oil used in silicone rubber is determined by its different silica gels. Therefore, the specific silicone oil to be used depends on the silica gel.

Vinyl silicone oil is used as base material, hydrogen-containing silicone oil is used as crosslinking agent, white carbon black is used as reinforcing agent, platinum catalyst and restraining agent are used to prepare two-component addition type liquid silicone rubber. The molar ratio of SiH in hydrogen-containing silicone oil to SiCHCH2 in vinyl silicone oil, hydrogen-containing silicone oil with different hydrogen content and the same viscosity, and hydrogen-containing silicone oil with different viscosity and the same hydrogen content on the adhesive properties of two-component addition type liquid silicone rubber were investigated. Impact.
