Uvioresistant heat dissipation dope for meter housings and preparation method of uvioresistant heat dissipation dope

Abstract

The invention discloses an uvioresistant heat dissipation dope for meter housings and a preparation method of the uvioresistant heat dissipation dope. The uvioresistant heat dissipation dope is made from the following materials in parts by weight: 30-35 parts of diphenol propane epoxy resin, 12-15 parts of aniline formaldehyde resin, 4-5 parts of ethenyl triamine DETA, 2-3 parts of aminoethyl piperazine AE, 4-6 parts of fatty glyceride, 10-14 parts of xylene, 10-12 parts of propylene glycol, 16-19 parts of ethyl acetate, 1-2 parts of catechol, 20-23 parts of aluminum nitride powder, 1-2 parts of nanometer titania, 3-5 parts of silane coupling agent and 5-6 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, the dope has excellent function of shielding ultraviolet and is not easily subjected to light aging; the dope has good lubricity, is easily applied, has large adhesive property, does not easily fall, is antibacterial and has good heat resistance.

Description

technical field [0001] The invention belongs to the technical field of paints, and relates to a heat-dissipating paint, more specifically, an anti-ultraviolet heat-dissipating paint 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 hav...

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.
