Abstract

The invention discloses an anti-corrosion heat-dissipation coating and a preparation method thereof. The coating comprises following raw materials: acrylic resin, calcium silicate powder, acetic ether, modified aluminium carbide, iron oxide, polyethylene wax powder, triethylene tetramine, anti-oxidant 264, water-soluble nano-level silica sol, dimethyl adipate, dispersant NNO, and acetone. The method adopts acrylic resin as the main material, which has the advantages of aging resistance, good adhesivity, good heat-dissipation effect, and long-term use at the temperature between 150 and 200 DEG C. Calcium silicate powder strengthens the anti-corrosion performance of the product, and alum and modified aluminium carbide strengthen the combination between the raw materials. The coating has the advantages of durability, waterproofness, damp-resistance, corrosion-resistance and very good adhesive performance.
