Problems solved by technology

However, an excessive amount of alumina can lead to a decrease in the fluidity, processability, and impact resistance of PP materials, resulting in a decrease in its practical value in the production of LED lighting products.
In addition, when PP materials are used in the production of LED lighting products and components of electromechanical products, their service life will be greatly reduced under the influence of ultraviolet rays

Description

Technical field [0001] The invention relates to the technical field of polymer resin materials, in particular to a thermally conductive anti-ultraviolet agent for PP and a thermally conductive anti-ultraviolet PP material prepared therefrom. Background technique [0002] Because polymer materials have the advantages of wide sources, low cost, and easy processing and molding, they are widely used. However, general polymer materials are thermal insulators, which limit their applications in electronic packaging, chemical heat transfer and other fields. In particular, more and more polymer materials are used in the production of LED products and electromechanical equipment. The lower thermal conductivity makes polymer materials unable to be further used in the production of parts for LED lighting products that generate more heat. At present, there are two main ways to improve the thermal conductivity of polymer materials: One is to synthesize intrinsic polymers with high thermal cond...
