Aluminum-based composite heat dissipation material containing glass wool and used for light LED (light-emitting diode)

Abstract

The invention relates to a lamp heat dissipation material, in particular to an aluminum-based composite heat dissipation material containing glass wool and used for a light LED (light-emitting diode). The heat dissipation material is prepared from the following raw materials in parts by weight: 80-83 parts of aluminum, 4-5 parts of copper, 2-3 parts of iron, 6-8 parts of aluminum nitride, 9-10 parts of titanium-silicon powder, 2-4 parts of glass wool, 3-5 parts of zinc oxide, 1-3 parts of chrome iron ores, 1-2 parts of manganese oxide ores, 0.2-0.3 part of hexadecyl trimethyl ammonium bromide, 6-8 parts of aluminum hydroxide, 1-2 parts of palmitic acid and 4-5 parts of auxiliaries. The heat dissipation material integrates advantages of raw materials such as the aluminum, the copper, the iron, the aluminum nitride, the glass wool, and the like, and has good heat conduction and insulating property; after being subjected to soaking treatment in a palmitic acid solution, the titanium silicon powder and the glass wool are more liable to be compatible with other raw materials so as to achieve good heat-absorbing and insulating properties. The heat dissipation material prepared in the invention is easy to process and form; and a prepared finished product is smooth and compact in surface, low in weight, high in strength and high in heat conduction coefficient, so that the service lives of lamps are effectively 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 containing glass wool for light 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 se...
