Acid and alkali resistant heat dissipating coating and preparation method thereof

Abstract

The invention discloses an acid and alkali resistant heat dissipating coating and a preparation method thereof. The coating is characterized in that raw materials composing the coating comprise, by weight, 48-55 parts of a furan resin, 2.8-3.2 parts of tetramethyl ethylenediamine, 60-70 parts of ethyl acetate, 2.8-3.5 parts of graphite powder, 2.5-3.5 parts of white carbon black, 1-2 parts of a silane coupling agent KH570, 3.0-4.0 parts of ultramicro wax powder, 3.8-4.5 parts of methyltris(methylethylketoximino)silane, 0.7-0.9 parts of an antioxidant 1010, 1.5-2.0 parts of polyvinyl alcohol, 1.4-1.6 parts of tripropyleneglycoln-butylether, 0.8-1.2 parts of fatty alcohol polyoxyethylene ether and 20-30 parts of aluminum nitride. The hybrid reaction of the graphite powder with aluminum nitride and the like under the action of the silane coupling agent increases the acid and alkali resistance of aluminum nitride, and the film of the coating has the advantages of good durability, good water resistance, good moisture resistance, good corrosion resistance and good adhesiveness.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an acid and alkali resistant heat dissipation coating and a preparation method thereof. Background technique [0002] With the rapid expansion of the scope of use of lamps, prolonging the service life of lamps has become an urgent problem to be solved; at present, heat-conducting adhesives are used to solve the heat dissipation problem of lamps, but the materials used have poor temperature resistance and aging resistance, and the adhesion to the substrate The technical problems of low power, poor heat dissipation and inconvenient construction make it difficult to meet people's requirements for heat dissipation of lamps. Contents of the invention [0003] The object of the present invention is to provide an acid and alkali resistant heat dissipation coating and a preparation method thereof. [0004] The present invention adopts following technical scheme: [0005] An ...
