Preparation method of cooling coating for led street lamp

Abstract

The invention discloses a preparation method of a cooling coating for an led street lamp. The method comprises the steps of firstly mixing a carboxyl carbon nano tube and hydroxylated kieselguhr; adding 4-vinylbenzyl chloride and triethanolamine borate to obtain an amidated esterification monomer through modification of thionyl chloride and triethylamine; and polymerizing the monomer in an amide alcohol dispersion liquid, wherein the obtained polymer has good characteristics of heat dissipation, rot resistance and high strength. The cooling coating has good heat dissipation due to the fact that the kieselguhr has an abundant micropore structure; the triethanolamine borate has good rot resistance; the strength and the toughness of the polymer are strengthened through the carbon nano tube; and plant ashes are also added, so that the heat dissipation effect of a finished product coating is further improved.

Description

technical field [0001] The invention belongs to the field of street lamp sheath coatings, and in particular relates to a preparation method of a heat dissipation coating for LED street lamps. Background technique [0002] The heat dissipation coating is to enhance the heat dissipation performance of the object by improving the radiation efficiency of the surface of the object (especially improving the infrared radiation efficiency). It has low cost and is simple to implement. The radiative heat dissipation cooling coating is directly applied to the surface of the object to be radiated and cooled. The radiative heat dissipation cooling coating can radiate heat from the object to the atmospheric space at an infrared wavelength of 8-13.5 μm, reducing the surface and internal temperature of the object, and the heat dissipation and cooling are obvious. The heat dissipation of the paint is not affected by the surrounding medium, and the heat dissipation of the paint can be used i...

Problems solved by technology

While the coating plays a role in radiation cooling, it can also increase the performance of self-cleaning, insulation, corrosion resistance, water resistance, acid and alkali resistance; the current heat dissipation coatings are generally used in the heat dissipation and cooling of components of electronic products such as CPUs. The heat dissipation of LED lamps has high requirements for the coating medium, and the adhesion to rough and loose surfaces is not strong, the use effect is not ideal, the scope of application is small, and some organic solvent-based heat dissipation coatings are poor in environmental protection, which is easy to cause environmental pollution
