In fact, silicone oil is closely related to our life. Many aspects of our life are applied to silicone oil, and the application range of silicone oil is very wide. It is not only used as a special material in aviation, cutting-edge technology and military technology departments, but also used in various departments of national economy. Its application scope has been expanded to: construction, electronic and electrical, textile, automobile, machinery, leather paper, chemical light industry, metal and paint, medicine and medical treatment, etc.

Silicone oil is a kind of polyorganosiloxane with different degree of polymerization. It is prepared by hydrolysis of dimethyldichlorosilane with water to obtain the primary polycondensated ring. The ring is cracked and rectified to obtain low ring. Then the ring body, capping agent and catalyst are put together to adjust and polymerize to obtain various mixtures with different polymerization degrees. The low boiling matter can be removed by vacuum distillation to obtain silicone oil.

According to the chemical structure, silicone oil can be divided into methyl silicone oil, ethyl silicone oil, phenyl silicone oil, methyl hydrogen silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil, methyl ethoxy silicone oil, methyl trifluoropropyl silicone oil, methyl vinyl silicone oil, methyl hydroxyl silicone oil, ethyl hydrogen containing silicone oil, hydroxyl hydrogen containing silicone oil, and cyanogen containing silicone oil; from the use, there are damping silicone oil and diffusion pump silicon Oil, hydraulic oil, insulating oil, heat transfer oil, brake oil, etc.

The most commonly used silicone oil, the organic group is all methyl, called methyl silicone oil. Organic groups can also use other organic groups instead of some methyl groups to improve some properties of silicone oil and apply to various uses. Other common groups are hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl, etc. In recent years, organic modified silicone oil has been developed rapidly, and many organic modified silicone oil with special properties has appeared.
