▎ 摘  要

NOVELTY - Heat conducting gasket comprises fillers (1), which are orderly arranged in inclined manner, and are formed by mixing a polymer matrix and heat conducting fillers. The heat conducting fillers comprises anisotropic heat conducting fillers (2), which are arranged in order in inclined manner. The angle of inclination is in the range of 15-45 degrees . USE - Heat conducting gasket. ADVANTAGE - The heat conducting gasket has high heat conducting performance and high compression performance and prepared in a simple and easy manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing, involves: (A) mixing a polymer matrix and a heat-conducting filler by using mixing equipment to obtain a mixed material, and ensuring that the heat-conducting filler is uniformly dispersed in the polymer matrix, where heat-conducting filler comprises anisotropic heat-conducting filler; (B) applying a magnetic field or an electric field to the obtained mixed material, where the direction of the magnetic field or the direction of the electric field and the thickness direction of the mixed material form a certain angle, and the angle is not 0-90 degrees; and (C) curing the polymer matrix to form the mixed material under the state of maintaining the orientation of the anisotropic heat-conducting filler for obtaining the heat-conducting gasket with orderly and obliquely arranged fillers. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a heat conducting gasket Filler (1) Anisotropic heat conducting filler (2) Isotropic heat-conducting filler (3)
