METHOD FOR PRODUCING HEAT-CONDUCTIVE SHEET, AND HEAT-CONDUCTIVE SHEET
Document Type and Number:
Japanese Patent JP2015044288
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat-conductive sheet having further-improved heat radiability.SOLUTION: A method for producing the heat-conductive sheet comprises: a step (I) of co-flocculating polytetrafluoroethylene fine particles and heat-conductive inorganic particles in an aqueous dispersion liquid containing the polytetrafluoroethylene fine particles and the heat-conductive inorganic particles, separating an obtained co-flocculate from a liquid component, and drying the co-flocculate to prepare a powder mixture containing the polytetrafluoroethylene fine particles and the heat-conductive inorganic particles; a step (II) of using the power mixture and a molding aid to prepare a plurality of sheet-shaped moldings each containing polytetrafluoroethylene, the heat-conductive inorganic particles and the molding aid; a step (III) of superposing the plurality of sheet-shaped moldings on one another and rolling a superposed material; and a step (IV) of removing the molding aid.
