Aluminum-based composite heat dissipation material for LED

Abstract

The invention relates to an aluminum-based composite heat dissipation material for an LED. The aluminum-based composite heat dissipation material is prepared from raw materials in parts by mass as follows: 68-70 parts of aluminum, 8-12 parts of aluminum nitride, 3-5 parts of silicon nitride, 2-4 parts of boron nitride, 4-8 parts of niobium diselenide, 10-14 parts of cellulose, 4-8 parts of silicon carbide micro-powder, 2-6 parts of dimethyl itaconate, 2-4 parts of titanium sulfate, 2-6 parts of sodium carbonate,2-3 parts of zirconium oxide sol and 4-5 parts of an auxiliary, wherein the auxiliary is prepared from raw materials in parts by mass as follows: 3-6 parts of mineral oil, 12-14 parts of cryolite fine powder, 3-7 parts of zirconium acetate, 2-4 parts of citric acid, 6-10 parts of iron powder, 4-8 parts of copper powder and 2-6 parts of potassium fluoroaluminate. The aluminum-based composite heat dissipation material for the LED is firm, tough, high in environmental corrosion resistance capacity, not prone to corrosion and durable, and has good heat conduction and heat dissipation capacity; the surface is not prone to wear.

Description

technical field [0001] The invention belongs to the technical field of LEDs, and in particular relates to an aluminum-based composite heat dissipation material for LEDs. Background technique [0002] At present, as a new generation of light source, LED has the advantages of energy saving, environmental protection, safety, low energy consumption, high brightness, etc., and is widely used in people's daily life. In actual use, the heat dissipation performance of the LED lamp itself is very important, because it not only directly affects the service life of the lamp, but also affects its lighting effect. Existing LED heat dissipation materials are mainly made of metal materials such as aluminum and copper. In actual use, there are disadvantages such as cost constraints and poor insulation performance. Therefore, it is necessary to improve the formula of the material to achieve a better heat dissipation effect. , Improve the performance of lamps and prolong their service life. ...
