The Application of Phenyl Silane

2020/03/10
Phenyl silane is a raw material for the preparation of silicone surfactants, and its application examples are as follows:

1. Preparation of a phenyl T10 cage silsesquioxane
Cage-like Silsesquioxanes (CSQ), also known as polyhedral oligomeric silsesquioxanes, is a generic term for a class of silsesquioxanes. CSQ is a general term for a class of caged silicones. The different CSQs are mainly due to the difference between n and R. CSQ is a three-dimensional cage structure. According to the difference of n, they are called T8, T10, T12, etc., respectively, corresponding to the cube (Oh) configuration, the pentagonal prism (D5h) configuration and the bowl-like (D2d) configuration.

2. Preparation of a room temperature curing type water resistant industrial top coating
Specifically, the polymer using methylsilane and phenyl silane is used for industrial coatings after solution polymerization with an aqueous fluorocarbon resin, an aqueous polyurethane resin, and a waterborne alkyd resin, respectively. This industrial coating has excellent weather resistance and moist heat resistance. Since the organic solvent is not used, the room temperature-curing aqueous weathering industrial topcoat produced has a very low organic volatile content. It is environmentally friendly.

3. Prepare a phenyl functionalized hydrophobic zeolite.
Porous minerals such as natural zeolites have received increasing attention due to their rich pore structure and good contaminant removal performance. A method of preparing a phenyl functionalized hydrophobic zeolite, comprising the steps of:The natural clinoptilolite is added to the phenyl silane coupling agent solution to complete the reaction, and then filtered, rinsed and dried to obtain a phenyl functionalized hydrophobic zeolite. The above preparation method allows the surface of the zeolite to contain a phenyl functional group by a phenylsilane coupling agent. The phenyl functionalized hydrophobic zeolite prepared by the method of the present invention can effectively adsorb aromatic organic pollutants.

4. Preparation of an octaphenyl cage silsesquioxane.

5. Prepare an antigen-oxygen polyimide hybrid film containing a POSS structure.
