Title (EN) ACRYLIC THERMAL CONDUCTIVE SHEET AND METHOD FOR PRODUCING THE SAME
(FR) FEUILLE ACRYLIQUE THERMO-CONDUCTRICE ET SON PROCÉDÉ DE PRODUCTION
Abstract:
(EN) To provide a thermal conductive sheet having improved thermal conductivity while maintaining flexibility and flame retardancy, and a method for producing the same. The above sheet can be obtained from hardened material comprising: a binder component (A) containing at least one alkyl (meth)acrylate monomer having an alkyl group of 12 to 18 carbon atoms and/or a partial polymer thereof; aluminum hydroxide particles (B) having an average particle diameter of 0.3 m or more and less than 4.0 m which are obtained by a crystallization method and are not subjected to a pulverization treatment; aluminum hydroxide particles (C) having an average particle diameter of 4.0 m or more and 15.0 m or less which are obtained by a crystallization method and are not subjected to a pulverization treatment, and also satisfy the relation: average particle diameter of the particles (C)/average particle diameter of the particles (B) = 3 to 15; and a reaction initiator (D); wherein the content of the component (A) is 100 parts by mass, the content of the component (B) is from 50 to 400 parts by mass, the content of the component (C) is from 50 to 1,000 parts by mass, and the content of the component (D) is from 0.01 to 5 parts by mass.
(FR) L'invention concerne une feuille acrylique thermo-conductrice possédant une meilleure conductivité thermique, tout en restant flexible et ininflammable, et son procédé de production. Cette feuille peut être obtenue à partir d'un matériau durci comprenant : un composant liant (A) contenant au moins un monomère de (méth)acrylate d'alkyle dont le groupe alkyle contient 12 à 18 atomes de carbone et/ou l'un de ses polymères partiels ; des particules d'hydroxyde d'aluminium (B) possédant un diamètre moyen de particules supérieure ou égale à 0,3 m et inférieure à 4,0 m, lesquelles sont obtenues par un procédé de cristallisation et ne sont pas soumises à un traitement par pulvérisation ; des particules d'hydroxyde d'aluminium (C) possédant un diamètre moyen de particules supérieure ou égale à 4,0 m et inférieure ou égale à 15,0 m, lesquelles sont obtenues par un procédé de cristallisation et ne sont pas soumises à un traitement par pulvérisation, et satisfaisant également la relation : diamètre moyen de particule des particules (C)/diamètre moyen de particule des particules (B) = 3 à 15 ; et un initiateur de réaction (D) ; la teneur en composant (A) étant de 100 parties en poids, la teneur en composant (B) étant de 50 à 400 parties en poids, la teneur en composant (C) étant de 50 à 1000 parties en poids, et la teneur en composant (D) étant de 0,01 à 5 parties en poids.
