Abstract

The invention provides a high-specific-heat-capacity heat conducting piece. The high-specific-heat-capacity heat conducting piece is prepared from, by weight, 20-50 parts of silicone rubber, 1-10 parts of silicon resin, 30-70 parts of heat conducting powder, 10-30 parts of a flame retardant, 30-70 parts of heat-absorption powder, 0.5-5 parts of a coupling reagent, 0.5-5 parts of a curing agent and0.5-5 parts of a catalyst, wherein the heat-absorption powder can improve the specific heat capacity, because the specific heat capacity is high and temperature slowly rises, the heat-conducting piece can absorb more heat, the heat conducting powder makes the heat conducting piece cooled more quickly, temperature rising and temperature lowering accelerate each other, the effects of absorbing moreheat and more quickly lowering the temperature are achieved, and the technical problem of heating in the fields of mobile communications and new energy automobiles can be well solved.

Description

technical field [0001] The invention relates to the technical field of a heat conduction sheet and a preparation method thereof, in particular to a large specific heat capacity heat conduction sheet, a preparation method and an application thereof. Background technique [0002] The large-capacity lithium battery pack is composed of many lithium battery cells connected in series and parallel. The lithium battery pack will generate a lot of heat energy during charging and discharging. How to conduct this heat energy to the outside as soon as possible to make the lithium battery pack quickly Reducing the temperature is a difficult problem in the current lithium battery industry. [0003] Similarly, in the field of mobile communication equipment, mobile phones will generate a lot of heat during charging and long-term use. How to transfer this heat to the outside as soon as possible is also a problem that needs to be solved urgently in the industry. [0004] At present, no matte...
