7、Luciferyl modified silicone oil
The polydimethylsiloxane containing Ryukyne in the side chain or end group is called Ryukyne-modified silicone oil, and the Ryukyne in its molecule can under the action of ultraviolet rays and photopolymerization initiators undergo a free-radical addition reaction with organosilicon compounds containing unsaturated bonds. This kind of silicone oil is the main component of ultraviolet light, electron beam curing silicone resin rubber, widely used in anti-adhesive isolation coating, but also can be used as a mold release agent.
8、other modified silicone oil
In addition to the above modified silicone oil, there are many other types of silicone oil, such as polydiorganosiloxane a polyether block copolymerization of modified silicone oil, alkyl and polyether co-modified silicone oil, alkyl ether polyether silicone oil, epoxy polyether silicone oil, amino-polyether segmented silicone oil, glycerol ether silicone oil, phosphoric acid based silicone oil, sugar-based polyether silicone oil, betaine-based silicone oil and so on. These silicone oils have different functional groups and therefore have special properties, but due to the low demand, the market share is small.
Silicone oil usually refers to linear polysiloxane products that remain liquid at room temperature, with the following structural formula: where R is alkyl, aryl, R' is alkyl, aryl, hydrogen, carbon-functional group, and polyether chain, etc.; X is alkyl, aryl, streptalkenyl, hydrogen, hydroxyl, alkoxy, acetyloxy, chloro v, carbon-functional group, and polyether chain, etc.; n, m=0, 1, 2, 3...
The most commonly used silicone oil, the organic groups are all methyl, called methyl silicone oil. Organic groups can also be used other organic groups instead of part of the methyl group, in order to improve a certain performance of the silicone oil and suitable for a variety of different uses. Common other groups are hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl and so on. In recent years, organic modified silicone oil has been rapid development, the emergence of many organic modified silicone oil with special properties.
