Problems solved by technology

[0003] At present, the surface coatings used are mainly concentrated on organic coatings. Such coatings usually use synthetic resins to form the coating surface film. Under high temperature conditions, due to their low heat dissipation performance, they may cause various adverse effects on the environment and the body.
For example, for rail transit locomotives, in the event of a sudden accident, if the excess heat inside the locomotive cannot be evacuated in time, the organic coating installed on the inner wall will cause harmful substances or volatilized harmful gases at high temperatures. Passengers who escape in time will pose a great health threat

Abstract

The invention provides a self-heat dissipating environment friendly nano coating and a preparation method thereof, belonging to the functional coating field. The formula of the coating is as follows: 15-65% of alumina sol, 15-65% of silica sol, 4-20% of nano composite oxides, 3-27% of pigment, 3-27% of filler, and 5-25% of anti-settling agent and the like. The preparation method of the coating has the following steps: respectively weighing and taking corresponding alumina sol, nano composite oxides, pigment, filler, anti-settling agent and the like to be mixed together, high speed dispersing and grinding to obtain a component a; weighing and taking corresponding silica sol to be a component b; and mixing the components a and b, standing, curing, and obtaining the self-heat dissipating environment friendly nano coating. Under the premise of unchanging the original preparation processes of the coating, the preparation method of the coating enhances the self-heat dissipating, far infrared releasing performances and the like by adding less nano-oxide composite system, has natural safe nontoxicity, and is an environment friendly nano coating.

Description

technical field [0001] The invention belongs to the field of functional coatings, and relates to a self-heating and environment-friendly nano coating and a preparation method thereof. Background technique [0002] Vehicles, military equipment, and semiconductor equipment often generate a lot of heat during use. In order to dissipate this part of heat in time, the existing technology, on the one hand, improves the heat dissipation parts of related machines; on the other hand, it uses surface coating to treat its surface to improve its surface thermal conductivity. [0003] At present, the surface coatings used are mainly concentrated on organic coatings. Such coatings usually use synthetic resins to form the coating surface film. Under high temperature conditions, due to their low heat dissipation performance, they may cause various adverse effects on the environment and the body. . For example, for rail transit locomotives, in the event of a sudden accident, if the excess ...
