Problems solved by technology

[0002] Transportation vehicles such as automobiles and trains, military equipment such as machine guns and cannons, semiconductor equipment such as integrated circuits and electronics, generate a lot of heat during use. In order to dissipate this part of the heat in time, at present, Teflon and other organic functional Coatings are used to achieve this function. 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.

Abstract

The invention provides an environmental protection type self-radiation nano ecological paint and a preparation method thereof, belonging to the field of functional paints. The nano ecological paint comprises the components: 15% to 80% of aluminum sol, 15% to 80% of silicon sol, 4% to 10% of nano heat conductive filler, 3% to 27% of pigment and 5% to 25% of anti-settling agent, wherein the nano heat conductive filler is a compound body of 2% to 5% of nano carbon tube and 2% to 10% of nano cobalt oxide or 2% to 10% of nano zirconia. The preparation method comprises the steps of: weighing corresponding aluminum sol, nano heat conductive filler, pigment, anti-settling agent and the like, mixing and rapidly dispersing the components as component a; weighing corresponding silicon sol as component b; and mixing, slowly dispersing, standing and curing components a and b for obtaining the nano ecological paint. The invention has the advantages that the powdery bodies of the nano cobalt oxide and the zirconia have self-radiation and far-infrared release functions; the nano powder is attached to the tube wall of the carbon tube to form a netty one-dimensional heat transmitting channel; and the heat transmitting characteristic of the paint is enhanced.
