Environmental protection type high-temperature resistant nano paint and preparation method thereof

Abstract

The invention provides an environmental protection type high-temperature resistant nano paint and a preparation method thereof, belonging to the field of functional paints, particularly to the field of high-temperature resistant paints. The environmental protection type high-temperature resistant nano paint comprises the components: 15% to 65% of aluminum sol, 15% to 65% of silicon sol, 4% to 20%of nano compound oxide, 3% to 27% of pigment, 3% to 27% of filler and 5% to 25% of anti-settling agent. The preparation method comprises the steps of: respectively weighing corresponding aluminum sol, cobalt oxide, pigment, filler and anti-settling agent, mixing, rapidly dispersing and grinding the components as component a; weighing corresponding silicon sol as component b; and mixing, standing and curing components a and b for obtaining a ceramic membrane paint. The prepared paint has the characteristics of high-temperature resistance, quick heat radiation, far-infrared radiation and the like; moreover, natural ore is adopted for replacing a traditional organic reagent and is used as the anti-settling agent; and the environmental protection type high-temperature resistant nano paint hasnatural safety non-toxicity.

Description

technical field [0001] The invention belongs to the field of functional coatings, especially the field of high temperature resistant coatings. Background technique [0002] At present, in the field of high-temperature-resistant coatings, organic functional coatings such as Teflon are often used. This type of coating usually uses synthetic resins to form a coating surface film, and its heat resistance is generally poor. Its heat dissipation performance is not high, which 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 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. [0003] In recent years, a kind of inorg...
