A kind of anti-oxidation heat-dissipating coating for instrument case and preparation method thereof

Abstract

The invention discloses anti-oxidant radiating paint used for a meter housing. The anti-oxidant radiating paint is prepared from the following raw materials in parts by weight: 40-45 parts of melamine formaldehyde resin, 2-3 parts of nano aluminum powder, 4-6 parts of dimethyl aminopropylamine, 40-45 parts of polyvinyl butyral, 20-23 parts of methyl ethyl ketone, 10-12 parts of ethyl acetate, 2-3 parts of acetic acid, 1-2 parts of antioxidant 168, 2-3 parts of boron carbide, 15-18 parts of aluminum nitride, 1-2 parts of magnesium oxide, 0.2-0.7 parts of tributyl phosphate, 1-2 parts of sodium metaphosphate, 12-15 parts of propylene glycol methyl ether acetate and 4-5 parts of coalescing agent. By adding the nano aluminum powder, the anti-oxidant radiating paint used for the meter housing disclosed by the invention has high heat conduction velocity and good radiating effect; by adding the boron carbide, the aluminum nitride and the magnesium oxide, the hardness and the wear resistance are improved; moreover, the paint is added with the antioxidant, and is antioxidant; the paint disclosed by the invention is good in lubricity, easy to construct, large in cohesive force, less in dropping possibility, ageing-resistant and long in service life.

Description

technical field [0001] The invention belongs to the technical field of paint, and relates to a heat-dissipating paint, more specifically, an anti-oxidation heat-dissipating paint for instrument shells 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.

Problems solved by technology

[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 such as poor temperature resistance and aging resistance, low adhesion to the substrate, poor heat dissipation effect and inconvenient operation, and it is difficult to meet the heat dissipation requirements.
