High-thermal-diffusion-coefficient high molecular material and preparation method thereof

The invention discloses a high-thermal-diffusion-coefficient high molecular material and a preparation method thereof. The high-thermal-diffusion-coefficient high molecular material is prepared from the following steps: 20-65 parts of matrix resin, 35-65 parts of high-thermal diffusion heat-conducting filler, 0.1-5 parts of carbon fiber composite, 0.1-10 parts of a flexibilizer, 0.1-2 parts of coupling agent, 0.1-2 parts of antioxidant and 0.1-15 parts of other auxiliaries. According to the high-thermal-diffusion-coefficient high molecular material, the heat conduction capability of the high molecular material is remarkably enhanced by virtue of the positive synergetic hybrid effect of a three-dimensional heat-conducting network formed by the high-thermal-diffusion-coefficient heat-conducting fillers different in shape in the processing course, and therefore the problems of poor heat conduction and thermal diffusion properties of the high molecular material for the existing LED lamp cooling housing are solved; in the preparation process, the compatibility between the surface modified high-thermal-diffusion-coefficient high molecular material and a resin matrix is improved, the viscosity of the synthetic resin melt is reduced and the dispersity of the filler is improved to enhance the processability; as a result, the product has excellent surface quality and mechanical properties; the high molecular material further has the advantages of high thermal conductivity and high tenacity.
