Abstract

The invention relates to a heat dissipation material for lamps, and in particular relates to a reinforced active aluminum-based composite heat dissipation material for an LED (light emitting diode) and a production method of the material. The heat dissipation material is prepared from the following raw materials in parts by weight: 83-85 parts of aluminum, 15-18 parts of aluminum nitride, 4-5 parts of magnesium nitride, 8-10 parts of zirconia, 4-6 parts of magnesium oxide, 1-3 parts of straw powder, 1-2 parts of tourmaline powder, 0.1-0.2 part of monazite slag, 0.5-1 part of natrolite and 4-5 parts of aids. The heat dissipation material disclosed by the invention integrates the advantages of aluminum, aluminum nitride, zirconia and the like, has good heat conduction and heat dissipation capabilities; the tourmaline powder is an active matter and can endow the material with good detergency, electromagnetic radiation reducing capability and moisture resistance, the monazite slag contains multiple rare earth elements and can effectively improve the heat dissipation performance of the material and can improve the sintering effect and the compactness of the material together with the aids. The material has good mechanical properties, is simple in use and maintenance and durable and can be used for effectively protecting an LED lamp and greatly prolonging the service life of the lamp.

Description

technical field [0001] The invention relates to a heat dissipation material for lamps, in particular to an enhanced active 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. ...
