Abstract
The invention discloses a water resistance thermal dissipation coating and a preparation method thereof. The composed raw materials are E-12 epoxy resin, amide curing agent, ethyl acetate, modified nano titanium dioxide, dimethicone, polyethylene wax powder, phthalic anhydride, anti-oxidant DLTP, sodium tripolyphosphate, tert-butyl peroxide, laurinol sodium sulfate, and propylene glycol. The method adopts E-12 epoxy resin as the main material, because the E-12 epoxy resin has the advantages of aging resistance, large adhesivity, good thermal dissipation effect, and can be used under 160 DEG C for a long time. The nano titanium dioxide and the dimethicone are modified, through coupling the silane coupling agent KH 550, complex structures of the nano titanium dioxide and the dimethicone are increases, which is benefit for the dispersion of the titanium dioxide and the hydrophobicity and has an effective waterproof performance. The coating film has the advantages of durability, water resistance, corrosion resistance and good adhesiveness.
