Abstract

The invention relates to a lamp radiating material and particularly relates to an aluminum-based composite radiating material for a high strength LED and a production method of the material. The radiating material is prepared from the following raw materials in parts by weight: 78-82 parts of aluminum, 5-7 parts of aluminum nitride, 1-2 parts of nanocarbon, 8-10 parts of nicochrome, 7-9 parts of nano ceramic powder, 12-15 parts of metakaolin, 1-2 parts of graphene, 5-8 parts of sodium aluminate, 2-4 parts of zinc sulfate, 3-5 parts of mulberry wood, 2-3 parts of folium mori powder and 4-5 parts of auxiliaries. The radiating material provided by the invention integrates the advantages of substances such as the nano ceramic powder, metakaolin, graphene, mulberry wood and the like; metakaolin is soaked by using a sodium aluminate solution, so that the radiating material is high in strength, hard to disintegrate at a high temperature and easy to form; the mulberry wood and folium mori powder which is soaked by the sodium aluminate solution and carbonized at the high temperature is strong in heat absorption. The radiating material prepared by the invention is smooth and compact in surface, has a high heat conductivity coefficient and a quick radiating capacity, and is good in insulating property, high in strength, strong in impact resistance, aging-resistant and long in service life.

Description

technical field [0001] The invention relates to a heat dissipation material for lamps, in particular to an aluminum-based composite heat dissipation material for high-strength 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. ...
