Document Type and Number:
Japanese Patent JP5646812
Kind Code:
B2
Abstract:
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.
