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] The present invention will be described in further detail below through specific embodiments, but the present invention is only limited to the following embodiments. Example

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

[0026] The preparation method is as follows:

[0027] (1) Weigh the components of the formula ratio, and then first add the carbon nanotubes to ethanol at a temperature of 50-80°C, and stir evenly;

[0028] (2) Then add the inorganic colloidal particles to the epoxy resin and methyl methacrylate mixed system and stir evenly;

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

[0030] The above-m...

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 an LED radiator, in particular to a coating for heat dissipation on the surface of an LED radiator with strong adhesion (adhesion level 1). technical background [0002] With the higher requirements for energy saving, emission reduction and environmental protection, more and more LED light sources are now used to replace traditional light sources; however, high-power LED light sources generate a large amount of heat, and if the heat is not timely, it is easy to greatly affect the life of the LED light source. influences. The LED light source and the substrate are connected by bonding and welding. The traditional heat dissipation mainly uses heat dissipation resin at the bonding place. However, as the temperature of the bonding place changes repeatedly, it is easy to affect the performance of the resin, causing the resin to age and peel off , Poor heat dissipation effect, in...
