Abstract

The invention relates to a nanometer material and a preparation method and application thereof. The nanometer material comprises 40 to 50 parts by weight of a polymer resin, 25 to 30 parts by weight of a solvent, 10 to 12 parts by weight of titanium dioxide, 6 to 8 parts by weight of silicon dioxide, 15 to 20 parts by weight of a silicon-based compound and 20 to 25 parts by weight of a diamond-like carbon compound. The nanometer material has the function of quickly exchanging hot and cold and can be widely used in preparation of the surface coating of the heat dissipation device. The nanometer material can utilize a simple spray-coating, smearing-coating or immersion-coating method, completely replace an expensive vacuum coating film and solve the problem of 3D curved surfaces. The nanometer coating film has excellent characteristics.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a nanometer material and its preparation method and application. Background technique [0002] There are only three ways to conduct heat, namely conduction, convection and radiation. Traditionally, heat dissipation is solved by conduction and convection, because at normal temperature, radiation heat dissipation is not obvious, and the effect of radiation is only significant when it is above 300°C. Radiation heat dissipation is a phenomenon in which heat is not conducted through objects, nor is it carried by liquid and gas, and the heat source is directly transmitted to various places in a non-linear 360° manner. Unlike traditional convection, the heat energy of radiation is released in the form of electromagnetic waves (full wavelength), so there is no need for physical contact between high-temperature objects and low-temperature environments, and there is no need for a medium...
