Abstract

The invention relates to a lamp radiating material and specifically relates to an aluminum-based composite radiating material for LED (light-emitting diode) doped neodymium oxide and a production method thereof. The radiating material is prepared from the following materials in parts by weight: 73-75 parts of aluminum, 10-12 parts of aluminum nitride, 4-5 parts of iron oxide black, 2-3 parts of neodymium oxide, 6-8 parts of steel slag, 10-12 parts of metakaolin, 6-8 parts of sodium silicate, 2-3 parts of ferrous sulfate, 2-5 parts of sucrose fatty acid ester and 4-5 parts of auxiliaries. The radiating material disclosed by the invention has integrated advantages of components such as aluminum, aluminum nitride, metakaolin, and the like, has good heat conduction and insulating performances; all materials are mixed and ground in sodium silicate aqueous liquor to increase compatibility of materials, so that the materials are easier to form; the doped neodymium oxide can improve radiating and temperature-resisting performances of the material; and the radiating material prepared in the invention is compact in structure, bright in color and luster, light and firm, good in thermal stability, durable, and efficient and lasting in radiating capacity, so that the LED lamp is effectively protected, and service life of the lamp is greatly prolonged.

Description

technical field [0001] The invention relates to a heat dissipation material for lamps, in particular to an aluminum-based composite heat dissipation material doped with neodymium oxide 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 ser...
