Abstract

The invention relates to heat dissipation materials for lamps, in particular to a low-cost dense aluminum-based composite heat dissipation material for LEDs and a production method thereof. The heat dissipation material is made of the following raw materials in parts by weight: aluminum 80-82, aluminum nitride 15-18, Barium carbonate 1-2, calcite 6-8, talc 10-12, dicalcium silicate 8-10, medical stone 3-5, manganese sulfide 1-2, zinc sulfate 3-4, zinc gluconate 1-3, Additives 4-5; the heat dissipation material of the present invention combines the advantages of aluminum, aluminum nitride, talc, additives and other components, and has good thermal conductivity and insulation performance. After soaking in the mixed aqueous solution of zinc sulfate and zinc gluconate Barium, calcite, talc, medical stone and other components are more compatible with metal powder and improve the sintering effect. The heat dissipation material prepared by the present invention has a compact structure, smooth surface, light weight, low cost, and durability, and can effectively protect LED lamps , greatly extending the service life of lamps.

Description

technical field [0001] The invention relates to a heat dissipation material for lamps, in particular to a low-cost dense aluminum-based composite heat dissipation material for LEDs and a production method thereof. Background technique [0002] LED is called the fourth-generation light source, which has the advantages of energy saving, environmental protection, safety, low energy consumption, and high brightness. It is widely used in daily life. The heat dissipation performance of the LED lamp itself is very important, which directly affects the service life of the lamp. and lighting effects. 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 limitations and insufficient 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. ...
