High-heat conductivity temperature-resistant aluminum-based composite radiating material for LED (Light-Emitting Diode)

Abstract

The invention relates to a lamp radiating material, and particularly relates to a high-heat conductivity temperature-resistant aluminum-based composite radiating material for an LED (Light-Emitting Diode) and a production method thereof. The radiating material is prepared from the following raw materials in parts by weight: 63-65 parts of aluminum, 15-18 parts of iron, 4-5 parts of magnesium nitride, 5-8 parts of vanadium diboride, 1-2 parts of zirconium diboride, 4-5 parts of ferrochrome slag, 8-10 parts of parts of gold ore tailings, 1-3 parts of propanetriol, 1-2 parts of triethanolamine, 0.5-0.8 part of boric acid, 12-14 parts of organic chelated titanium and 4-5 parts of auxiliary agents. The radiating material disclosed by the invention integrates the advantages of components, namely the aluminum, the iron, the vanadium diboride, the gold ore tailings and the like, has good heat-conducting property and insulating property and can be used for enhancing the resource utilization ratio by removing impurities contained in the gold ore tailings and the ferrochrome slag by carrying out soaking treatment on the gold ore tailings and the ferrochrome slag by utilizing a dilute boric acid solution; the radiating material prepared through the production method disclosed by the invention has the advantages of ideal sintering effect, smoothness and compactness of a material surface, stability in temperature change, durability and excellent heat-conduction coefficient and can be used for effectively protecting the LED lamp and greatly prolonging the service life of the lamp.

Description

technical field [0001] The invention relates to a heat dissipation material for lamps, in particular to a high thermal conductivity and temperature-resistant 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 lam...
