FRICTION TRANSMISSION BELT AND MANUFACTURING METHOD THEREFOR

Japanese Patent JP2017110806

A

PROBLEM TO BE SOLVED: To provide a friction transmission belt capable of enhancing heat radiation from a belt even under a severe condition easily causing thermal deterioration, and suppressing temperature rise of the belt.SOLUTION: A friction transmission belt is manufactured by coating a friction transmission face with a heat radiation layer including heat conductive metallic particles through an anchor layer including a thermoplastic resin layer. Heat conductive metallic particles may exist on a surface of the heat radiation layer. Heat conductivity of the heat conductive metallic particles may be 100 W/m L or more. An average particle diameter of the heat conductive metallic particles may be about 1-100 μm. The friction conductive belt 1 includes an extension layer 4 forming a belt back face, a compression layer 2 disposed on one face side of the extension layer, and a core body 3 buried between the extension layer 4 and the compression layer 2, and extended in a belt circumferential direction. A friction conductive face of the compression layer 2 may be coated with a heat radiation layer 6 composed of vulcanizate of a rubber composition including a rubber component and the heat conductive metallic particles, through an anchor layer 5 including polyolefin.SELECTED DRAWING: Figure 1
