overview
A polymer material that is repellent to adhesives, used to produce silicon release paper and film release coatings. Silicone can also be used as an ink additive to help ink flow and improve the scratch resistance and flexibility of the ink. Silicone can also be used in some pressure-sensitive adhesives to withstand extreme temperatures; it can also be used as a lubricant in self-adhesive formulations to improve the paper cutting performance of the paper cutter, and can be applied to both sides of the cutting edge of the paper cutter To prevent the accumulation of adhesive.
synthesis method
Up to now, organic silicon synthesis methods mainly include direct synthesis method, silicon hydrogen addition method, hydrolysis condensation method, organometallic method, etc. Although these methods are relatively mature and widely used, some methods also have some obvious shortcomings. For example, the silicon-hydrogen addition method usually requires precious metal platinum catalysts, which is costly, the reaction process requires inert gas protection, the reaction time is long, and the product selectivity is relatively poor. The residue of platinum catalysts in the product affects the application of materials in biomedicine and other fields. Moreover, with the expansion of the application range of silicone materials, traditional synthesis methods have been difficult to meet many new requirements for the structure and performance of materials. Therefore, in recent years, researchers have devoted themselves to developing new methods to prepare silicone materials. Thanks to the rapid development of Chinese law in organic chemistry and polymer chemistry, some new and efficient synthesis methods have been used in silicone synthesis.
