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
The present invention relates to technical field of coatings, be specifically related to a kind of acid and alkali-resistance heat radiation coating and preparation method thereof.
Background technology
Along with the rapid expansion of light fixture use range, prolong light fixture and also become urgent problem work-ing life; Adopt at present heat-conducting glue to solve the light fixture heat dissipation problem, but there is heatproof and ageing-resistant poor in its employed material, the technical problem little to the base material cohesive force, that radiating effect is not good and construction is inconvenient is difficult to satisfy people to the requirement of light fixture heat radiation.
