2. Different preparation methods: Organosilicon: Organosilicon compounds can be synthesized through various methods, such as linking organic groups with elements such as oxygen, sulfur, and nitrogen.
Organic silicon resin: Its preparation usually involves the use of a mixture of methyltrichlorosilane, dimethyldichlorosilane, etc., hydrolysis in organic solvents, and then the formation of a highly cross-linked three-dimensional network structure through condensation reaction.
3. Performance characteristics:
Organic silicon: It has a unique structure, such as a methyl shielded high-energy polysiloxane main chain on Si atoms, non-polar C-H bonds, etc., which makes organic silicon materials have good heat resistance, electrical properties, water resistance, weather resistance, and certain mechanical strength.
Organic silicon resin: low mechanical strength, poor solvent resistance, and poor adhesion to substrates such as metals and plastics. In addition, the compatibility of silicone resin is limited and requires modification to be compatible with other organic resins.
