Embodiment Construction

[0013] The radiation cooling coating of the present invention comprises the following components, 2-15 parts of titanium phosphate, 10-20 parts of aluminum oxide, 1-10 parts of aluminum nitride, 0.1-0.5 parts of silane coupling agent, 10-20 parts of water-based ring Oxygen resin, 20-80 parts of water. Titanium phosphate is rich in pores, easy to coagulate and produce binding force, strong adhesion, good infrared emission and light reflection performance. Aluminum nitride has a high infrared emission rate in the low temperature range, but the price is more expensive; alumina has a high infrared emission rate in the low temperature range, and the price is low, which is conducive to cost control. Silane coupling agent is used to modify the surface of raw materials and enhance the film-forming hardness of coatings.

[0014] The radiation cooling paint of the present invention also includes 0-5 parts of carbon black, which can color the paint and make the paint have higher thermal...

Abstract

The invention discloses a radiation heat dissipation cooling coating and a production technology thereof. The radiation heat dissipation cooling coating comprises the following components: 2-15 parts of titanium phosphate, 10-20 parts of aluminum oxide, 1-10 parts of aluminum nitride, 0.1-0.5 part of silane coupling agent, 10-20 parts of waterborne epoxy resin and 20-80 parts of water. Due to the titanium phosphate inorganic colloidal particles, the average particle size of the radiation heat dissipation cooling coating is less than 100 nanometers, condensation occurs to generate a binding force, so that the coating surface has nano material components showing a form which is smooth and clean from macroscopic view and rough in microscopic view, the contact area between a heat dissipation device and the outside can be greatly increased, and the heat dissipation effect is obviously improved.

Description

technical field [0001] The invention relates to a radiation cooling paint; the invention also relates to a production process of the radiation cooling paint. Background technique [0002] Radiation cooling and heat dissipation coating is a kind of coating that takes away the heat of objects through radiation and insulates and waterproofs. The temperature resistance range is -50-600 ° C. The coating is directly painted on the surface of the object to be cooled and cooled. The radiation cooling and cooling coating can be 8-13.5 The μm infrared wavelength radiates heat from the surface of the substrate to the surrounding space, reducing the surface and internal temperature of the substrate, and the heat dissipation and cooling are obvious. Radiation cooling and heat dissipation coatings have high radiation cooling properties and are more convenient to use. They can be painted in thin layers or thick layers. The coatings also have excellent protection and decoration functions. ...
