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]
The present invention relates to thermally conductive material, particularly relate to a kind of can damping noise reduction, absorb the multi-functional heat-conductive composite material that hertzian wave that the plasm TV display panel produces is converted into heat energy then and the heat that produces on the display panel is led away together.
[background technology]
In Plasmia indicating panel, discharge gas is sealed between the top glass substrate and lower glass substrate with a plurality of electrodes, provide discharge gas producing ultraviolet ray, and the ultraviolet ray excited fluorescent layer that forms in predetermined display unit send visible light, with effective acquisition image.
Plasma shows that module regulates the display unit discharge according to video data and hold time, and promptly keeps the number of times of discharge, thereby realizes showing the gray scale that needs.
Therefore, in order to produce dynamic image, show the high-tension actuate signal of using in the module of high frequency at plasma, can make the Plasmia indicating panel of forming by upper substrate and lower basal plate produce a large amount of heat and noise, also can emit than chromatic cathode tube or the more hertzian wave of display panels simultaneously.
In order to solve described heat radiation, noise reduction, suction ripple problem, prior art is normally directly pasted heat conduction pad or graphite heat-conducting fin by the display panel back.In actual applications, because most of electronic products has all required to inhale ripple, function of shielding, during particularly directly in the face of the user, need the hertzian wave that electrical equipment produces directly be shielded or absorb.Particularly for plasma television, panel produces a large amount of heat in use, and the power supply of back can produce vibrations under high frequency environment, and noise occurs, and problems all have influence on the appreciation effect of user's article on plasma body TV.What present stage, backboard used later is heat conduction pad or graphite flake, and the heat conduction pad is the silica type material, and good damping noise reduction function and heat conduction function are arranged, and graphite sheet has good heat conduction function.Yet also there is open defect in above-mentioned materials, and the effect of heat conduction pad damping noise reduction is fine, but heat-conducting effect is undesirable; Though the graphite sheet heat-conducting effect is fine, the damping noise reduction effect is bad, and these two kinds of materials are not converted into the function that thermal conductance is walked with hertzian wave after not having the ripple of suction.
[summary of the invention]
The present invention is intended to solve the shortcoming of prior art, not only has damping noise reduction and inhales wave energy and provide a kind of, simultaneously can be with the multi-functional heat-conductive composite material that changes into heat energy after the absorption of electromagnetic wave on the display panel and lead away.
For achieving the above object, the invention provides a kind of multi-functional heat-conductive composite material, this matrix material is to be composited by by weight percentage following component:
In another program of the present invention, this multi-functional heat-conductive composite material is, and to be 10～40 silicon rubber, 0.5～20 vulcanizing agent, 0～5 catalyzer with weight percent content mix mutually with 55～89 functional stuffing, and described mixture coating or calendering is online and form at aluminium foil or aluminium.
Described silicon rubber is selected from one or more in firm silicone rubber, liquid silastic, the trifluoropropyl siloxane.
Described vulcanizing agent is selected from organo-peroxide, contain one or more of the multifunctional silane compound of hydrolysable group, containing hydrogen silicone oil.
Described catalyzer is selected from a kind of in organic tin catalyzer, platiniferous class catalyzer, the titanate ester catalyzer.
Described functional stuffing be by aluminium powder and heat conduction aluminum oxide by 55～90: 45～10 weight percent mixes.
Described aluminum powder particle size is between 800～5000 orders, and foreign matter content is lower than 1%.
Described heat conduction aluminum oxide grain size is between 200～5000 orders, and foreign matter content is lower than 0.1%, and water content is lower than 0.5%.
Described aluminum foil thickness is less than 0.5mm.
The thickness of described aluminium net is less than 0.5mm, and the order number of mesh is between 200～2000 orders.
Contribution of the present invention is, it efficiently solves heat conduction pad or the existing defective of graphite flake that heat radiation, noise reduction, suction ripple are used.Matrix material of the present invention can directly be close on the display panel, thereby the vibrations that produce on the display panel are eliminated, and noise can be reduced to the degree that the user can not discover.Change into heat energy after the hertzian wave that produces on the display panel is absorbed, and dissipate by the backboard that this matrix material passes to the back.Characteristics such as matrix material of the present invention has material and is easy to get, and manufacture craft is simple, and is easy to implement.
