More Information
Summary:The invention discloses a high-strength heat-conducting silica gel gasket and a preparation method thereof, and the high-strength heat-conducting silica gel gasket is suitable for the fields of heat dissipation of new energy lithium batteries and the like. A carbon fiber powder material is wetted and dispersed and surface modified by adopting an organic volatilizable dilution solvent and a coupling agent. A carbon fiber dispersion liquid is brushed on the upper surface of a substrate gasket. With the volatilization of the organic dilution solvent, carbon fibers can be arranged parallel to theplane of the heat-conducting gasket, so that the high heat-conducting performance of the carbon fiber material along the fiber axial direction is exerted, and the gasket has a good heat equalizing function in the plane direction of the gasket. The directionally arranged carbon fiber material can play a role similar to skeleton strengthening and greatly improve the etching and tearing and other mechanical properties of the
