Abstract

The invention relates to the lamp heat dissipation materials, and particularly relates to a highly-antirust aluminum-based composite heat dissipation material used for LEDs and a producing method thereof. The heat dissipation material is prepared from following raw materials by weight: 60-65 parts of aluminum, 10-11 parts of iron, 5-8 parts of magnesium nitride, 1-1.5 parts of stannous pyrophosphate, 1-2 parts of zinc phosphate, 0.4-0.5 part of calcium phosphate, 0.1-0.2 part of strontium phosphate, 8-10 parts of clay, 12-15 parts of quartz sand, 10-12 parts of silicon carbide, 6-8 parts of aluminum-rich andalusite and 4-5 parts of auxiliary agents. The heat dissipation material integrates advantages of the aluminum, the iron, the magnesium nitride, the clay, the quartz sand, the silicon carbide, and the like and has good heat conducting and thermal insulation properties. The raw materials are fully mixed. Sintering effects are good. The prepared heat dissipation material has characteristics of compact structure, bright and clean surfaces, whether tolerance, water resistance, capability of being not liable to rust and durable in use, good heat dissipation capability, capability of protecting LED lamps and delaying the luminous decaying speed, good using properties and long service lifetime.

Description

technical field [0001] The invention relates to a heat dissipation material for lamps, in particular to a high antirust 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. C...
