Problems solved by technology

This kind of paint usually uses synthetic resin to form the coating surface film, and its heat resistance is generally poor, and, at high temperature, it often causes various adverse effects on the environment and the body.
For example, for rail transit locomotives, in the event of a sudden accident, if the interior of the locomotive is fumigated by high temperature or the excess heat cannot be evacuated in time, the organic coating installed on the inner wall will cause harmful substances or volatilization at high temperatures. The harmful gas will pose a great health threat to the passengers who do not escape in time

Abstract

The invention provides an environment-friendly nano ceramic film coating with a self heat radiating function and a preparation method thereof, belonging to the field of functional coating. The formula of the coating is as follows: 15-65% of alumina sol, 15-65% of silica sol, 4-20% of cobalt oxide, 3-27% of pigment, 3-27% of packing, 5-25% of anti-settling agent and the like. The preparation method comprises the following steps: respectively weighing the corresponding alumina sol, cobalt oxide, pigment, packing, anti-settling agent and the like, mixing, dispersing at high speed and grinding toobtain a component a; weighing the silica sol with a corresponding weight as a component b; and mixing the component a and the component b, standing and aging to obtain the ceramic film coating. The coating and the preparation method thereof are based on inorganic film forming raw materials, and the cobalt oxide is added to ensure that the invention has the characteristics of high-temperature resistance, fast heat radiation, far infrared radiation and the like, simultaneously has the quality of an enamel surface, strong decoration, safety and no toxicity, and is an environment-friendly high-temperature resistant coating.

Description

technical field [0001] The invention belongs to the field of functional coatings, and relates to an environment-friendly nano-porcelain coating with a self-radiating function and a preparation method thereof. Background technique [0002] At present, high-temperature-resistant coatings are mainly used in engines and exhaust pipes of vehicles such as automobiles and trains, military equipment such as machine guns and cannons, and semiconductor equipment such as integrated circuits and electronics. This type of paint usually uses synthetic resin to form the coating surface film, and its heat resistance is generally poor, and, at high temperature, it often causes various adverse effects on the environment and the body. For example, for rail transit locomotives, in the event of a sudden accident, if the interior of the locomotive is fumigated by high temperature or the excess heat cannot be evacuated in time, the organic coating installed on the inner wall will cause harmful sub...
