Long-oil alkyd resin radiating paint used for meter housing and preparation method thereof

Abstract

The invention discloses long-oil alkyd resin radiating paint used for a meter housing. The long-oil alkyd resin radiating paint is prepared from the following raw materials in parts by weight: 20-30 parts of long-oil alkyd resin, 10-12 parts of E-12 epoxy resin, 2-3 parts of methylene bicyclohexylamine, 20-23 parts of nano aluminum nitride powder, 5-7 parts of tributoxy ethyl phosphate, 10-12 parts of nonyl phenol, 4-5 parts of silane coupling agent KH550, 5-8 parts of mica powder, 4-6 parts of polyvinyl butyral, 5-7 parts of polyimide, 2-3 parts of pentaerythritol triacrylate and 4-5 parts of coalescing agent. By adding the nano aluminum nitride powder, the long-oil alkyd resin radiating paint used for the meter housing disclosed by the invention has high heat conduction velocity and good radiating effect; by adding the mica powder, the paint has excellent wear resistance. The paint disclosed by the invention uses the long-oil alkyd resin, has good weather resistance and salt water resistance, insulation, gloss and toughness; moreover, the paint is easy to construct and good in cohesiveness.

Description

technical field [0001] The invention belongs to the technical field of paints, and relates to a heat-dissipating paint, in particular to a long-oil alkyd resin heat-dissipating paint used for instrument cases 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...

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.
