Problems solved by technology

At this time, the heat generated by electronic equipment accumulates and increases rapidly. Under the ambient temperature, in order to ensure the normal operation of electronic components with high reliability for a long time, the ability to dissipate heat in time becomes an important limiting factor affecting their service life.
The existing method to effectively improve the heat dissipation effect of powder coatings is mainly to fill the powder coating with metal or graphite powder, which leads to the inability of the product to meet its insulation performance requirements during use. Therefore, a kind of heat dissipation performance is prepared. Better paint is necessary

Abstract

The invention provides a high-heat-dissipation insulating composite coating for an electric appliance. The coating is prepared from the following components in parts by mass: 40-50 parts of bisphenolA epoxy resin, 12-16 parts of alkyd resin, 1-4 parts of fiber slurry, 13-16 parts of nitride, 1-3 parts of hydroxyl silicone oil, 15-18 parts of filler, 2-5 parts of gamma-(2,3-epoxypropoxy)-propyltrimethoxysilane, 5-7 parts of polydimethylsiloxane, 3-10 parts of a curing agent and a proper amount of a solvent. Through the reasonable raw material formula and compounding and cooperations among thecomponents, the coating is uniform and level, the heat conduction and dissipation performance of the coating is greatly improved, the insulating property is good, and the adhesive force of the coatingis high; the coating also has excellent temperature resistance, fire resistance, wear resistance, weather resistance and the like, the use safety of electric appliances is remarkably improved, and the service life of the electric appliances is remarkably prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a composite coating with high heat dissipation and insulation for electrical appliances. Background technique [0002] With the rapid development of industries such as aviation, aerospace, automobiles and weapons, the requirements for material protection are getting higher and higher. Some components need to work in high temperature and corrosive environments, and at the same time have physical properties such as fatigue resistance and thermal shock resistance. and insulation and other functional properties. Insulating coatings have excellent electrical insulation properties and are widely used in the field of electrical performance components. Organic insulating coatings are prone to aging and do not have flame retardant function. The inorganic coating has the characteristics of high temperature resistance, corrosion resistance, and no mildew, which can protect the substrate ...
