Problems solved by technology

However, the above-mentioned materials also have obvious defects. The heat conduction gasket has a good effect of shock absorption and noise reduction, but the heat conduction effect is not ideal; although the graphite sheet has a good heat conduction effect, the shock absorption and noise reduction effect is not good. It does not have the function of converting electromagnetic waves into heat conduction after absorbing waves

Abstract

The present invention relates to a multifunctional heat-conductive composite material, which is formed by mixing 10-40wt% of silicone rubber, 0.5-20wt% of a vulcanizing agent, 0-5wt% of a catalyst and 55-89wt% of functional filler; or by mixing 10-40wt% of silicone rubber, 0.5-20wt% of a vulcanizing agent, 0-5wt% of a catalyst and 55-89wt% functional filler, and then coating or calendering the mixture on an aluminum foil or an aluminum mesh, wherein the functional filler is formed by mixing 55-90wt% of aluminite powder with 45-10wt% of heat-conducting alumina; and the aluminum foil or aluminum mesh is less than 0.5 mm in thickness and the size of a mesh of the aluminum mesh is 200-2000 meshes. The multifunctional heat-conductive composite material provided by the invention not only has the functions of damping, noise reducing and wave absorbing, but also is capable of absorbing the electromagnetic wave on a display panel and transforming the electromagnetic wave into heat energy. The composite material provided by the invention is mainly used for the heat conduction of the backboards of large plasma televisions, LCD (liquid crystal display) and other electric appliances.

Description

【Technical field】 [0001] The invention relates to a heat conducting material, in particular to a multifunctional heat conducting composite material capable of reducing shock and noise, absorbing electromagnetic waves generated by a plasma TV display panel and converting them into heat energy, and conducting away the heat generated on the display panel. 【Background technique】 [0002] In a plasma display panel, a discharge gas is sealed between an upper glass substrate and a lower glass substrate having a plurality of electrodes, the discharge gas is supplied to generate ultraviolet rays, and the ultraviolet rays excite a fluorescent layer formed in a predetermined display unit to emit visible light to effectively Get the image. [0003] The plasma display module adjusts the discharge maintenance time of the display unit according to the video data, that is, the number of sustain discharges, so as to realize the gray scale required for display. [0004] Therefore, in order t...
