Description
Technical Field
The invention relates to a rubber material, in particular to an improved heat-conducting synthetic rubber, and belongs to the field of rubber production.
Background
The current heat-conducting silicone rubber is a type of silicone rubber formed by adding a specific conductive filler on the basis of silicone rubber. Different heat-conducting silicon rubbers need to be filled with different electric-conducting fillers, and the heat conductivity coefficients of the heat-conducting silicon rubbers are greatly different. Existing conductive fillers include silicon dioxide, aluminum oxide, silicon carbide, silicon nitride, magnesium oxide, magnesium carbonate, zinc oxide, aluminum nitride, and the like. The conductive filler commonly used at present is alumina, and manufacturers can generally manufacture different heat conductivity coefficients, curing speeds, viscosities, colors, hardness and the like to adjust according to requirements. However, the heat conductivity coefficient of the existing heat-conducting silicon rubber adopting alumina as the conductive filler is only 1.5-2, and the heat-conducting silicon rubber is easy to stick rollers and difficult to demould during production.
