ROLL-TYPE COMPOSITE SHEET WITH IMPROVED HEAT DISSIPATION PROPERTY, ELECTROMAGNETIC WAVE, AND IMPACT-ABSORBING PROPERTY, AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a roll type composite sheet which not only requires additional adhesive layer, in which the production cost can be reduced by simplifying production steps, but also minimizes production failures, and which can be applied to light, thin, and small-type electrical, electronic, and communication apparatuses, while having composite functions for effectively dissipating and absorbing heat and electromagnetic waves generated inside of the sheet that effectively absorbs external impacts.;SOLUTION: The method of manufacturing the roll type composite sheet whose heat dissipation property, electromagnetic wave properties, and impact absorption properties are improved uses silicone gel having a specific property to give superior heat dissipation property and heat and impact absorption property to the composite sheet. The superior adhesive property of the silicone gel requires no additional adhesive layer to be formed, so that not only is each sheet not required to be processed one by one, but production cost is reduced through a simplified production steps.;COPYRIGHT: (C)2009,JPO&INPIT
