ABSTRACT:
Provided are a heat resistant laminated conveyor belt and manufacturing method thereof by which a belt surface pressure when a liner and corrugated core paper are pressed and bonded together can be increased to thereby enhance a bonding performance. The heat resistant laminated conveyor belt comprises a belt core layer11made by a heat resistant non-metallic fiber substrate being impregnated with a fluororesin dispersion and then dried and sintered and a surface layer13(plain weave wire, etc., for example) formed on the belt core layer11via an adhesive layer12made by a fluororesin film, the surface layer having a fabric structure using an element wire or wires made of a ferrous metal or having a structure in which the element wire or wires are arranged together.As the surface layer13, a fabric structure using an element wire or wires made of a non-ferrous metal, inorganic compound, organic compound or carbon is used or a structure in which the element wire or wires are arranged together (plain weave wire, parallel wire, etc., for example) is used. As the element wires, stranded wires, parallel wires or the like are used.
