Silicone oil generally refers to linear polysiloxane products that remain liquid at room temperature. Generally divided into two types: methyl silicone oil and modified silicone oil. The most 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 hydrophobic properties. It is obtained by hydrolyzing dimethyldichlorosilane with water to obtain the primary polycondensation ring body. The ring body is cracked and rectified to obtain the low ring body, and then the ring body, the capping agent and the catalyst are put together to obtain each A mixture of different polymerization degrees can be obtained by vacuum distillation to remove low-boiling substances.
