Vinyltriisopropoxysilane applications properties production
Description of vinyl triisopropoxy silane
Vinyl triisopropoxy silane has attracted much attention in the chemical industry. It has unique properties and shows important functions in many application scenarios.
Properties
Vinyl triisopropoxy silane often has a colorless and transparent liquid appearance and a special odor. Its chemical properties are active. Due to the existence of vinyl and siloxy groups in the molecule, it not only has the reactivity of unsaturated double bonds, but also can chemically react with hydroxyl groups and other groups, thus showing unique reaction properties. And under specific conditions, it can undergo hydrolysis and condensation reactions to form silicone structural polymers, which makes it promising for material modification and other aspects.
Application
1. ** In the field of composite materials **: Widely used as a coupling agent. In glass fiber reinforced plastics, it can effectively improve the interfacial bonding force between glass fibers and resin matrices. Vinyl triisopropoxysilane molecules The vinyl at one end can copolymerize with the resin matrix, and the siloxy at the other end can form a chemical bond with the hydroxyl group on the surface of the glass fiber after hydrolysis. This significantly enhances the mechanical properties of the composite, such as tensile strength and flexural strength. At the same time, it also enhances the water resistance and weather resistance of the composite.
2. ** In the coating industry **: Can be used as a coating additive. It can improve the adhesion of the coating to the substrate, because it can react with the hydroxyl group on the surface of the substrate to form a strong chemical bond, and at the same time participate in the coating film formation process to improve the hardness, wear resistance and chemical corrosion resistance of the coating. If vinyl triisopropoxysilane is added to the metal anti-corrosion coating, it can effectively prevent the corrosion medium from eroding the metal and prolong the service life of the metal.
3. ** In the rubber industry **: It plays an important role as a modifier. It can improve the interaction between the rubber and the filler, so that the filler can be better dispersed in the rubber, thereby enhancing the physical and mechanical properties of the rubber. For example, in the manufacture of tires, the addition of this substance can enhance the adhesion strength of the tread rubber and the cord, improve the wear resistance and tear resistance of the tire, and prolong the service life of the tire
The production of
vinyl triisopropoxysilane is often made of vinyl trichlorosilane and isopropanol as the main raw materials. Under specific reaction conditions, under the action of suitable catalysts, the two are obtained by alcoholysis. During the reaction process, factors such as reaction temperature, raw material ratio and reaction time need to be strictly controlled to ensure high reaction yield and product purity. Subsequent process steps such as separation and purification are required to remove impurities such as unreacted raw materials and by-products to obtain high-purity vinyl triisopropoxysilane products. In this way, it can meet the strict requirements of product quality in different application fields.
