Abstract
(EN)
A method for manufacturing a heat dissipation sheet is provided. A heat dissipation sheet, according to one embodiment of the present invention, is manufactured by comprising the steps of: (1) preparing a preliminary sheet comprising a matrix forming component, a crosslinking agent, and a heat dissipation filler; and (2) manufacturing a heat dissipation sheet by crosslinking the matrix forming component included in the preliminary sheet. According to this, the manufactured heat dissipation sheet can be provided with a high content of the heat dissipation filler, so that heat dissipation performance thereof is remarkably excellent. In addition, it is possible to minimize and prevent breakage, shrinkage, pore generation, thickness variation, etc. of the sheet caused by the material properties of the matrix forming component and the crosslinking of the matrix forming component to form a matrix despite being implemented to have excellent heat dissipation performance, and it is possible to have excellent flexibility. Furthermore, as the processability is improved through a cooling process or the like during the manufacture of the heat dissipation sheet, the heat dissipation sheet is very excellent in productivity and may be suitable for mass production.

L'invention concerne un procédé de fabrication d'une feuille de dissipation de chaleur. Une feuille de dissipation de chaleur, selon un mode de réalisation de la présente invention, est fabriquée en comprenant les étapes consistant à : (1) préparer une feuille préliminaire comprenant un composant de formation de matrice, un agent de réticulation et une charge de dissipation de chaleur ; et (2) fabriquer une feuille de dissipation de chaleur par réticulation du composant de formation de matrice inclus dans la feuille préliminaire. Selon l'invention, la feuille de dissipation de chaleur fabriquée peut être pourvue d'un contenu élevé de la charge de dissipation de chaleur, de telle sorte que la performance de dissipation de chaleur de celle-ci est remarquablement excellente. De plus, il est possible de réduire au minimum et d'empêcher la rupture, le retrait, la génération de pores, la variation d'épaisseur, etc. de la feuille provoqués par les propriétés de matériau du composant de formation de matrice et la réticulation du composant de formation de matrice pour former une matrice malgré leur mise en œuvre pour avoir une excellente performance de dissipation de chaleur, et il est possible d'avoir une excellente flexibilité. En outre, étant donné que l'aptitude au traitement est améliorée par l'intermédiaire d'un procédé de refroidissement ou similaire pendant la fabrication de la feuille de dissipation de chaleur, la feuille de dissipation de chaleur est très excellente en productivité et peut être appropriée pour une production en masse.
