Abstract

The invention discloses an insulation pad and a preparation method thereof. The insulation pad comprises the following components by weight percentage: 12-18 percent of silicone polymer or polyurethane and polymeric resin, 50-60 percent of heat conductive powder, 25-35 percent of wave absorption power, and adjuvant in balancing amount. The insulation pad has all the characteristics of a simple heat conductive insulation pad, meanwhile can absorb electromagnetic wave, and is easy in the preparation method and implement, safe and reliable.

Description

technical field [0001] The invention relates to the field of insulating materials, in particular to a wave-absorbing and heat-conducting insulating gasket and a preparation method thereof. Background technique [0002] With the development of integration technology and the intensive assembly of microelectronics, the heat generated by electronic equipment accumulates and increases rapidly. Every time the temperature of electronic components rises by 2°C, its reliability decreases by 10%. Therefore, whether it can dissipate heat in time becomes an important factor affecting its service life. [0003] In order to ensure that electronic components can still work with high reliability under the ambient temperature of use, it is necessary to develop thermally conductive and insulating polymer composite materials to replace traditional polymer materials as a thermally conductive interface material to quickly transfer heat from heating elements to heat dissipation equipment to prote...
