Silicone oil generally refers to a linear polysiloxane product that maintains a liquid state at room temperature. The structural formula is as follows:
In the formula, R is an alkyl group, an aryl group, R′ is an alkyl group, an aryl group, a hydrogen atom, a carbon functional group, a polyether chain, and the like; and X is an alkyl group, an aryl group, an alkenyl group, a hydrogen atom, a hydroxyl group, or an alkoxy group. , acetoxy, chlorine v, carbon functional groups and polyether chains; n, m=0, 1, 2, 3...
The most commonly used silicone oils, all organic groups methyl, said methyl silicone oil. Organic groups can also use other organic groups instead of partial methyl groups to improve certain properties of the silicone oil and for a variety of different applications. Other common groups are hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl and the like. In recent years, organically modified silicone oils have been rapidly developed, and many organically modified silicone oils having special properties have appeared.
According to the chemical structure of silicone oil 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 silicon oil, methyl trifluoromethane Based on silicone oil, methyl vinyl silicone oil, methyl hydroxy silicone oil, ethyl hydrogen silicone oil, hydroxy hydrogenated silicone oil, cyanide-containing silicone oil, etc.; from the use of points, there are damping silicone oil, diffusion pump silicon oil, hydraulic oil, insulating oil, Heat transfer oil, brake oil, etc.
