Preparation method of heat-dissipation coating for led streetlamp

Abstract

The invention discloses a preparation method of a heat-dissipation coating for a led streetlamp. The preparation method comprises the following steps: mixing carboxyl carbon nano tubes with hydroxylating diatomite at first; modifying the mixture by using thionyl chloride and triethylamine; adding 4-vinylbenzyl chloride and triethanolamine borate in the mixture to obtain amidated esterification monomers; polymerizing the monomers in amphenicol dispersion liquid to obtain polymer which has good heat dissipation property, corrosion resistance and high strength. The heat dissipation property is good due to the fact that the diatomite has abundant micro-pore structures, the triethanolamine borate has good corrosion resistance, by the carbon nano tubes, strength and toughness of the polymer are enhanced, plant ash is further added in the polymer, and therefore, the heat dissipation effect of the finished 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
