▎ 摘　　要

NOVELTY - The material has a thermally conductive base layer (1), a graphene composite thermally conductive sheet and a thermally conductive covering layer (3). The thermally conductive base layer is divided to form a grid, and any two adjacent grids are placed with a graphene composite thermally conductive sheet and place only one graphene composite thermal conductive sheet in any two adjacent grids. The heat-conducting cover layer is arranged on the heat-conducting substrate on which the graphene composite heat-conducting sheet is placed. The area of the graphene composite thermal conductive sheet is s times the area of each grid grid, and the s value is 0.1-1. USE - Composite thermal conductive material with soft surface with a grid distribution for forming variety of grid structures for electronic, electric appliance, automobile and instrument. ADVANTAGE - The composite thermal conductive material utilizes the grid distribution of the graphene composite thermal conductive sheet in the thermal silica gel to form a variety of grid structures, and the specific grid placement position is not limited, and is determined by oneself according to actual needs. The composite thermal conductive material keeps the material surface low hardness and has a certain degree of bendability. The locally highly concentrated heat is quickly diffused, which improves the uniformity and efficiency of heat dissipation through the action of the graphene composite thermal conductive sheet, when the heat passes through the grid-distributed graphene composite thermal conductive sheet. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the composite heat conducting material with gridding distributed surface. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the composite thermal conductive material. Thermally conducting base layer (1) Thermally conductive covering layer (3)
