POLY(HYDRIDOSILSESQUIOXANE) - Introduction
Dimethylsilyl cage polysilsesquioxane is a kind of polymer with special structure. Its structure contains cage-shaped silsesquioxane units, and siloxane is an inorganic polymer composed of two elements, silicon and oxygen.
This compound has the following properties:
1. High temperature stability: It has excellent high temperature resistance and can still maintain its chemical and physical properties under high temperature environment.
2. low surface tension: due to its cage structure, the interaction between liquid molecules formed on the interface is strong, thus reducing the surface tension of the liquid and contributing to wetting and diffusion.
3. optical transparency: has good optical transparency, suitable for the preparation of optical devices and coating materials.
4. electrical insulation: with good electrical insulation properties, commonly used as an insulating layer of electronic materials.
The application fields of dimethylsilyl cage polysilsesquioxane include:
1. High temperature lubricant: Due to its high temperature stability, it can provide good friction reduction and anti-wear performance under high temperature lubrication conditions.
2. Coating material: It can be used to prepare coating materials with heat resistance, corrosion resistance and wear resistance.
3. Sealing material: It has excellent sealing performance and can be used to prepare high-pressure sealing and vacuum sealing materials.
4. Optical film: Because of its optical transparency, it can be used to prepare optical devices and optical film materials.
The preparation method of dimethylsilyl cage polysilsesquioxane is usually carried out by polymerization reaction. Specific methods include:
1. Reverse reaction polymerization method: Polysilsesquioxane is produced by reacting silane monomers under specific conditions, for example, under acidic conditions.
2. Solution polymerization method: silane and other polymers are mixed and dissolved, and then reacted in a specific solvent system to generate polysilsesquioxane.
Regarding safety information, dimethylsilyl cage polysilsesquioxane is generally stable and safe under normal use conditions, but the following precautions may exist:
1. Since dimethylsilyl cage polysilsesquioxane is commonly used as a lubricant and coating material, it is necessary to avoid prolonged contact with skin and eyes to reduce the risk of irritation and eye or skin damage.
2. in handling or use, should pay attention to follow the chemical safety procedures, such as wearing appropriate protective equipment (such as gloves, safety glasses).
3. During storage and transportation, it is necessary to avoid contact with oxygen, acid, strong oxidants and other substances to avoid dangerous chemical reactions.
This information is intended to provide a general understanding, and specific use and safety details should be determined according to the specific specifications and conditions of use of the product. Before use, the technical description and safety data sheet of the product should be read carefully.
