Silicon resin powder

Abstract

The invention provides silicon resin powder which is prepared from the following components in parts by weight: 15-35 parts of methyl vinyl polysiloxane, 10-15 parts of diphenyl trichlorosilane, 5-10 parts of acrylic polymer powder, 5-10 parts of calcium oxide, 10-20 parts of silicon carbide, 5-15 parts of water-based amino resin, 5-10 parts of novolac epoxy resin, 10-20 parts of nitrile-butadiene rubber and 2-5 parts of molybdenum disulfide. The silicon resin powder provided by the invention has favorable adhesive force, solvent resistance, heat-resistance temperature and storage stability.

Description

technical field [0001] The invention relates to a silicone resin powder. Background technique [0002] Waterborne coatings, as a major environmentally friendly coating, have become a research hotspot. In particular, waterborne silicone polymer coatings are one of the most promising coating varieties developed in recent years. Silicone coatings are coatings with silicone polymers or silicone modified polymers as the main film-forming substance. It has excellent heat and oxygen aging resistance, cold resistance, electrical insulation, corona resistance, radiation resistance, moisture resistance and water repellency. , weather resistance, stain resistance and chemical corrosion resistance have developed rapidly in product performance improvement and application in recent years. [0003] At present, my country's electronics, construction, medical and health industries are developing rapidly, which provides a broad market for the application of water-based silicone coatings.
