The invention belongs to the technical field of materials, and discloses an insulating heat-conducting gasket and a preparation method thereof. The preparation method includes: mixing raw materials containing a thermal conductive filler and a polymer matrix material to form a slurry, placing the slurry in a centrifuge cylinder, adjusting the centrifugal speed so that the slurry is dispersed along the cylinder wall of the centrifuge cylinder and centrifuging , and heat curing to make insulating thermal pads. The centrifugal method is adopted, so that most of the thermally conductive fillers are concentrated on one surface, which has the effect of heat conduction, and most of the polymer matrix materials are concentrated on the other surface, which has the effect of insulation. The use of this kind of gasket with good thermal conductivity in the electronic field can effectively solve the problems of slow heat dissipation, low work efficiency and short service life in electronic equipment, and the gasket has good insulation performance without causing electronic equipment. Conductive phenomenon. |
