Problems solved by technology

At present, the general LED lamp does not adopt special heat dissipation measures, and uses the natural heat dissipation of the lamp housing. This method causes the lamp housing to age after the LED lamp has been used for a period of time. Due to the long-term high temperature of the lamp housing, the service life of the LED is reduced; it cannot meet Development Status and Requirements of LED Lamps

Abstract

A heat-curing heat-conducting and heat-dissipating coating and a preparation method thereof, characterized in that it is made of the following raw materials in parts by weight: silicone resin 32-35, melamine formaldehyde resin 12-14, xylene 21-23, ethyl acetate 24-26 , butanol 8-10, aluminum nitride powder 26-28, diaminodiphenylmethane 2-3, diisopropylethanolamine 4-5, benzoin 1-2, di-n-octyl-4-isothiazoline- 3-ketone 1-2, mica powder 12-15, itaconate 4-6, isopropyl dioleate acyloxy (dioctyl phosphate acyloxy) titanate 3-5, vinyl tri( β-methoxyethoxyl) silane 2-3, film-forming agent 4-5; The present invention adopts di-n-octyl-4-isothiazolin-3-ketone, which has increased the anti-mold performance of coating, long-term storage, Will not deteriorate and produce odor.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a heat-dissipating coating, more specifically, a heat-curing heat-conducting and heat-dissipating coating and a preparation method thereof. Background technique [0002] With the rapid expansion of the use range of LED lamps, prolonging the service life of LED lamps has become an urgent problem to be solved. At present, the general LED lamp does not adopt special heat dissipation measures, and uses the natural heat dissipation of the lamp housing. This method causes the lamp housing to age after the LED lamp has been used for a period of time. Due to the long-term high temperature of the lamp housing, the service life of the LED is reduced; it cannot meet The development status and requirements of LED lamps. Contents of the invention [0003] The object of the present invention is to provide a heat-curing heat-conducting and heat-dissipating coating and a preparation method the...
