<p>PROBLEM TO BE SOLVED: To improve heat resistance, oil resistance, abrasion resistance and bending resistance without generating contamination of environment at the time of burning this belt by forming a compressed rubber layer of a polymer bridged material composed of ethylene, (meta) acrylic ester and a bridge component. SOLUTION: A transmitting belt is formed of a core 11, an adhesive rubber layer 12, a compressed rubber layer 13 and canvas 14, 15. The compressed rubber layer is formed of a polymer bridged material composed of ethylene, (meta) acrylic ester and a bridge component, and a three-dimensional copolymer using ethylene, (meta) acrylic ester and a third monomer as a bridge component is used. As a third monomer, acrylic acid, methacrylic acid, acrylonitrille, vinyl acetate or the like is used. The adhesive rubber layer is formed of the organic acid included polymer such as carboxylated NBR. Since this transmitting belt does not include chrorine compound, even in case of burning this belt, harmful material is not generated. Failure and deterioration is not reported from a result of traveling test.</p> |
