Abstract

The invention discloses an aging resistance thermal dissipation coating and a preparation method thereof. The aging resistance thermal dissipation coating is characterized by being composed of following components, in parts by weight, 50 to 60 parts of alkyd resins, 1.7 to 2.3 parts of amine curing agent, 70 to 85 parts of acetone, 6.0 to 7.0 parts of zinc oxide, 2.3 to 2.8 parts of ferrophosphorous powder, 5.0 to 6.0 parts of ultramicro wax powder, 2.5 to 3.5 parts of urotropine, 1.2 to 1.5 parts of anti-oxidant 1035, 1.8 to 2.2 parts of aging resistance agent OD, 10 to 15 parts of propenoic acid-4-hydroxybutyl ester, 2.0 to 3.0 parts of diffusion agent NNO, 25 to 30 parts of aluminium nitride, 1 to 2 parts of tert-butyl peroxide, and 2 to 3 parts of vinyltriethoxysilane. The method improves the aging resistance performance of ingredients and strengthens the aging resistance performance of the coating film through the coupling between the aging resistance agent and the silane coupling agent, propenoic acid-4-hydroxybutyl ester, and zinc oxide, therefore the coating film has the advantages of durability, water-resistance, damp-resistance, good corrosion-resistance and good adhesivity.
