▎ 摘　　要

NOVELTY - Preparing longitudinal high heat conducting gasket involves uniformly mixing the material to obtain the mixed material, the material comprises a binder and anisotropic heat-conducting filler, coating the mixture material on the surface of the base material, obtaining the coating on the surface of the base material, processing the coating obtained to the semi-vulcanized state to obtain the semi-vulcanized state coating, coating the mixture material again on the semi-vulcanized state coating obtained, coating vulcanizing forming, slicing along the direction vertical to the coating to obtain product. USE - Method for preparing longitudinal high heat conducting gasket used in preparing heat-conducting product (claimed). ADVANTAGE - The method is simple and easy to realize large-scale continuous production, and effectively removes the air bubbles, and improves the heat-conducting performance of the material.
