Problems solved by technology

[0002] With the higher requirements of energy saving, emission reduction and environmental protection, more and more LED light sources are used to replace traditional light sources; however, high-power LED light sources generate a lot of heat, and if the heat dissipation is not timely, it is easy to have a great impact on the life of LED light sources. influences
The LED light source and the substrate are bonded and welded together. The traditional heat dissipation mainly uses heat-dissipating resin at the bonding point to dissipate heat. However, as the temperature of the bonding point changes repeatedly, it is easy to affect the performance of the resin, causing the resin to age and peel off. , poor cooling effect, increased energy consumption

Embodiment Construction

[0024] Describe the present invention in further detail below by specific embodiment, but the present invention is only limited to following embodiment. Example

[0025] All raw materials of the present invention, unless otherwise specified, are commercially available products, such as the diatomite of MGZ-800 produced by Shenzhen Yoshida Chemical Co., Ltd.

[0026] The preparation method is as follows:

[0027] (1) Weighing each component of the formula ratio, then adding the carbon nanotubes into ethanol at a temperature of 50-80°C, and stirring evenly;

[0028] (2) Then the inorganic colloidal particles are added to the mixed system of epoxy resin and methyl methacrylate and stirred evenly;

[0029] (3) Mix the solutions of step (1) and step (2), then add spinel after electronic transition, rare earth element oxide, nano-diatomite and stabilizer and stir evenly to obtain the surface heat dissipation of LED heat sink with paint.

[0030] The spinel electron radiation men...

Abstract

The invention discloses paint with strong adhesion for cooling the surface for an LED (light emitting diode) radiator. The paint is characterized by being prepared from the following components in parts by weight: 10-25 parts of inorganic colloidal particles, 1-3 parts of carbon nano-tube, 25-90 parts of electron transited spinel, 0.05-1.5 parts of rare earth oxide, 0.1-0.5 part of a stabilizing agent, 3-15 parts of epoxy resin, 2-10 parts of methyl methacrylate, 10-25 parts of nano- diatomite and 2-10 parts of ethylene glycol. The paint has remarkable heat dissipating and cooling effects, is not influenced by peripheral media, can be used in a vacuum environment, plays a role in radiating and cooling, and has the advantages of good self-cleaning performance, corrosion resistance, water resistance, flame retardance, insulating performance and acid-alkali resistance, and is convenient to construct.

Description

technical field [0001] The invention relates to the technical field of coatings for cooling the surface of LED radiators, in particular to a coating for cooling the surfaces of LED radiators with strong adhesion (adhesion level 1). technical background [0002] With the higher requirements of energy saving, emission reduction and environmental protection, more and more LED light sources are used to replace traditional light sources; however, high-power LED light sources generate a lot of heat, and if the heat dissipation is not timely, it is easy to have a great impact on the life of LED light sources. influences. The LED light source and the substrate are bonded and welded together. Traditional heat dissipation mainly uses heat-dissipating resin at the bonding point to dissipate heat. However, as the temperature of the bonding point changes repeatedly, it is easy to affect the performance of the resin, causing the resin to age and peel off. , the heat dissipation effect is...
