Problems solved by technology

However, an excessive amount of alumina can lead to a decrease in the fluidity, processability, and impact resistance of PA materials, resulting in a decrease in its practical value in the production of LED lighting products.
In addition, when PA materials are used to produce parts of LED lighting products, they are extremely prone to aging under the influence of strong light and high temperature, causing discoloration, embrittlement, cracking and other problems, and their service life will be greatly reduced

Description

technical field [0001] The invention relates to the technical field of polymer resin materials, in particular to an anti-oxidation enhanced heat conduction agent for PA and an anti-oxidation heat conduction PA material prepared therefrom. Background technique [0002] Due to the advantages of wide sources, low cost, and easy processing and molding, polymer materials have been widely used, but generally polymer materials are thermal insulators, which limits their applications in electronic packaging, chemical heat transfer and other fields. In particular, more and more polymer materials are put into the production of LED products, and the low thermal conductivity prevents polymer materials from being further applied to the parts of LED lighting products with high heat generation. At present, there are two main ways to improve the thermal conductivity of polymer materials: one is to synthesize intrinsic polymers with high thermal conductivity, such as polyacetylene, polypyrrol...
