A kind of high-gloss high-whiteness heat-dissipating insulating coating and preparation method thereof

Abstract

The invention relates to the technical field of paint, in particular to high-gloss and high-brightness heat dissipating insulating paint and a preparing method thereof. The paint comprises epoxy primer and organic silicon finish paint. The epoxy primer comprises, by mass, 8-30% of epoxy resin, 5-40% of silicon carbide, 0-40% of aluminum nitride, 1-3% of dispersing agent, 1-3% of coupling agent, 4-15% of curing agent, 8-20% of xylene and 3-10% of n-butyl alcohol. The organic silicon finish paint comprises, by mass, 10-30% of organic silicon resin, 5-15% of titanium dioxide, 10-40% of aluminum oxide, 0-30% of boron nitride, 0-20% of magnesium oxide, 1-3% of dispersing agent, 1-3% of coupling agent, 10-30% of DBE and 0-20% of butyl ester. The paint has the advantages of being high in heat dissipating performance, insulating performance, reflectance and brightness, resistant to high temperature and the like; the preparing method of the paint is high in production efficiency, environmentally friendly and safe.

Description

technical field [0001] The invention relates to the technical field of coatings, and relates to a high-gloss and high-whiteness heat-dissipating insulating coating and a preparation method thereof. Background technique [0002] Heat dissipation and insulating coatings are a kind of special functional coatings, which are widely used in electrical appliances, electronics, mechanical equipment, lamps, etc. On the one hand, it has a good heat dissipation effect on the heating metal, and at the same time, it has the safety performance of insulation, which may realize heat dissipation and cooling or heat exchange under insulation conditions. There are many types of heat-dissipating and insulating coatings, such as polyimide resin, polyether ketone or epoxy-modified silicone and other resins, adding silicon carbide, beryllium oxide, mica powder, zirconia and other insulating and heat-conducting fillers, but the existing The overall performance of insulation and heat conduction app...

Problems solved by technology

There are many types of heat-dissipating and insulating coatings, such as polyimide resin, polyether ketone or epoxy-modified silicone and other resins, adding silicon carbide, beryllium oxide, mica powder, zirconia and other insulating and heat-conducting fillers, but the existing Insulation and heat conduction applied to LED lamps have poor overall performance, some have insufficient heat dissipation capability, some are not resistant to high voltage shocks, some turn yellow and change color under high temperature for a long time, and some have low light and heat reflectivity

These will affect the service life and quality and safety of LED lights
