LED aluminum-base composite heat dissipation material containing modified powdered pumice

Abstract

The invention relates to lamp heat dissipation materials, in particular to an LED aluminum-base composite heat dissipation material containing modified powdered pumice and a production method of the material. The heat dissipation material comprises, by weight, five to eight parts of zirconium silicate, seven to nine parts of silicon carbide, 70 to 72 parts of aluminum, three to five parts of pentaerythritol, 13 parts to 15 parts of aluminum nitride, 10 parts to 12 parts of magnesium, five parts to eight parts of copper nanoparticles, eight parts to ten parts of the powdered pumice, seven parts to eight parts of aluminum oxide, three parts to five parts of silicone oil, six parts to eight parts of potassium titanate whisker, two parts to four parts of etidronic acid and four parts to five parts of auxiliaries. According to the heat dissipation material, advantages of the aluminum, the magnesium, the zirconium silicate, the silicon carbide and other components are integrated, the good heat conduction and insulation performance can be both considered, the modified powdered pumice formed by mixing of etidronic acid dilute solutions, the silicone oil and the pentaerythritol and the potassium titanate whisker are more compatible with other metal powder, heat conductivity coefficients are improved, the heat dissipation material is compact in structure, light, safe and durable in use, an LEDF chip can be effectively protected due to the rapid heat dissipation capability, and the service life of a lamp is 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 modified pumice powder 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 th...
