PRE-CURED SINGLE-COMPONENT THERMAL GEL AND PREPARATION METHOD THEREFOR

Disclosed are a pre-cured single-component thermal gel and a preparation method therefor. The pre-cured single-component thermal gel is prepared from the following components in parts by weight and a platinum catalyst: 100 parts of vinyl-terminated silicone oil, 5-30 parts of branched hydrogen-containing silicone oil, 500-2500 parts of modified thermally conductive powder, and 0.01-0.3 part of an inhibitor; the content of the platinum catalyst is 2 ppm to 10 ppm on the basis of the mass of platinum; the modified thermally conductive powder is prepared by modifying thermally conductive powder with a modifier; and the modifier consists of long-chain alkyl silane and vinyl silane. Compared with existing single-component thermal gels, the prepared pre-cured single-component thermal gel has the advantages of excellent thermal conductivity, a high extrusion rate and low oil permeability.
