Abstract

The invention relates to a nanometer heat dissipating paint and a preparation method thereof. The preparation method comprises the following steps: a. dissolving a fluorocarbon resin as the base material in a mixed solvent, so as to obtain a base-material mixed liquid; b. dissolving a filler with a pore structure in the mixed liquid with the weight ratio of the filler to the base material being 0.2-0.33, so as to obtain a filler mixed liquid; c. filtering the base-material mixed liquid obtained in the step a and the filler mixed liquid obtained in the step b; and d. uniformly stirring and mixing the filtered base-material mixed liquid and the filtered filler mixed liquid in the step c. The fluorocarbon resin is used as the base material and mixed with the filler with the pore structure, so as to obtain the nanometer heat dissipating paint with good anti-pollution property and high thermal diffusivity.

Description

technical field [0001] The invention relates to a nano heat dissipation coating and its preparation method, especially a design which uses a fluorocarbon resin as a base material and mixes a filler with a pore structure, and utilizes the pore structure of the filler to improve heat dissipation. Background technique [0002] Heat dissipation components such as metal heat sinks and heat pipes have good heat dissipation effects, but they are expensive and not suitable for lightweight product design, so there is development and application of heat dissipation coatings. However, after the existing heat-dissipating coatings are cured on the heat-dissipating surface to form a heat-dissipating layer, the base material used has poor pollution resistance such as weather resistance, heat resistance, low temperature resistance, and chemical resistance, resulting in the formation of the heat dissipation coating after curing. The heat dissipation of the heat dissipation layer is easily re...
