High Level Alloy Silicon Carbide Powder

A wear-resistant and stain-resistant coating film for mouse touch panel glass, wherein the raw materials include, by weight: 80-120 parts of polyester resin, 60-80 parts of epoxy resin E-22, 30-60 parts of epoxy resin 601, 20-50 parts of zinc phosphate, 10-30 parts of aluminum tripolyphosphate, 2-8 parts of sericite, 3-9 parts of nano-diatomite, 2-8 parts of montmorillonite, 1-5 parts of silicon carbide, 3-5 parts of black silicon carbide powder, and 1-5 parts of ceramic micropowder , 2-4 parts of white jade powder, 1-5 parts of adhesion promoter, 1-5 parts of dispersant, 2-4 parts of leveling agent, 3-5 parts of defoamer, 2-4 parts of chlorinated paraffin, 1-5 parts of titanium dioxide, 2-4 parts of carbon black, 1-5 parts of polyamide 650, 2-4 parts of 2,4,6-tris(dimethylaminomethyl)phenol, 2-6 parts of mixed solvent. The wear-resistant and stain-resistant coating used for mouse touch panel glass has excellent adhesion, wear resistance and stain resistance.

1.A production method of reaction sintering carbonization. The main characteristics are as follows: 5-8 parts by weight of black silicon carbide powder, 0.5-1.5 parts of carbon black, 1-1.5 parts of graphite, and 0.1-0.5 parts of a binder; wherein the silicon carbide particle size distribution is: 3-5 parts of SIC (90-30 μm), 2-3 parts of SIC (30-0.8 μm); 0.1-0.5 parts of methyl cellulose and polyvinyl alcohol powder respectively; the vacuum sintering process is divided into low temperature 0-700 ° C, preservation Keep it for 3-5 hours; keep it for 4-6 hours at medium temperature 700-1400℃; keep it for 5-7 hours at high temperature 1400-2200℃, and add 1-3 parts by weight of metal silicon. The raw materials and proportions used are scientific and reasonable, so that the blank has sufficient porosity and the blank has the best density; the optimal sintering heating speed, temperature and insulation time ensure the high flexural strength of the product. The main performance and quality of the products produced by this method have reached the international advanced level.
