Abstract

The invention provides an anticorrosion heat dissipation powder coating. The powder coating comprises the following components in parts by weight: 40-90 parts of matrix resin, 2-40 parts of curing agent, 0.5-2 parts of additive, 0-4.5 parts of hexagonal boron nitride, 0-15 parts of aluminium nitride, 0-10 parts of magnesium nitride, 0-10 parts of silicon carbide and 5-30 parts of pigments and fillers. The powder coating has good heat dissipation effects and high efficiency improvement rate above 60%, has the effect of reducing the temperature by more than 20 DEG C, can effectively solve the problem that high-power electronic products have poor heat dissipation effects, and can prolong the service lives of the electronic products.

Description

technical field [0001] The invention relates to a powder coating, in particular to an anti-corrosion and heat-dissipating powder coating. [0002] Background technique [0003] Powder coating is a new type of solvent-free, 100% solids powder coating. It has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. It has two categories: thermoplastic powder coating and thermosetting powder coating. Thermoplastic powder coatings are composed of thermoplastic resins, pigments, fillers, plasticizers and stabilizers. Thermoplastic powder coatings include: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, polyester. Thermosetting powder coatings are composed of thermosetting resins, curing agents, pigments, fillers and additives. Thermosetting powder coatings include: epoxy resin, polyester, acrylic resin.
