Heat dissipation dope for meter housings and preparation method of heat dissipation dope

Abstract

The invention discloses a heat dissipation dope for meter housings and a preparation method of the heat dissipation dope. The heat dissipation dope is prepared from the following materials in parts by weight: 45-50 parts of organic silicon resin, 18-22 parts of n-butyl acetate, 14-16 parts of ethyl acetate, 2-3 parts of nanometer titania, 2-3 parts of tributyl tin trichloride, 4-6 parts of tetraethylenepentamine TEPA, 1-2 parts of nano-graphite, 2-3 parts of graphene, 16-19 parts of aluminum nitride powder, 2-3 parts of mica powder, 1-2 parts of allyl heptanoate, 1-2 parts of 4-methyl guaiacol, 5-6 parts of ethanediol and 4-5 parts of film forming assistant. By adding aluminum nitride powder, the dope has high heat conduction rate and good heat dissipation effect; by adding nanometer titania, so that the dope has excellent function of shielding ultraviolet ray, is good for health and is not easily aged; by adding nano-graphite, the dope has good lubricity and is easily applied; organic silicon resin is used as a base material of the dope, so that the dope has good insulation property and excellent thermal oxidation stability.

Description

technical field

[0001] The invention belongs to the technical field of coatings, and relates to a heat-dissipating coating, more specifically, a cooling coating used for an instrument case and a preparation method thereof. Background technique

[0002] With the advancement of science and technology, various instruments have emerged as the times require. Generally, the heat emitted by the instrument will not be very fast, but because the instrument will work for a long time, it will accumulate a lot of heat. If the heat is not released in time, it will cause the instrument to overheat and affect the normal operation. Work, also easily destroyed. At present, there are relatively few coatings designed for the working characteristics of the instrument, which cannot meet the requirements of production and life, and the problem of heat dissipation has been paid more and more attention. The materials used in the current instrument heat dissipation coatings have technical problems ...
