A long-lived triangular belt

Abstract

The invention provides a rubber composition for manufacturing V-belts, and adding trans-isoprene (TPI) as a modifier is beneficial to improve the flex resistance of V-belts, which can be doubled, thereby prolonging the service life of V-belts . The V-belt prepared by the invention has good flex resistance and long service life, and can be used as a V-belt for automobiles.

Description

technical field [0001] The invention relates to the technical field of molding rubber for V-belts, in particular to a composition for manufacturing V-belts. Background technique [0002] V-belts for automobiles need to run at high speed. If the heat dissipation is not good, the flex resistance is poor, and the life of the tape is short. The patent CN2300761Y provides a high-strength V-belt, which improves the wear resistance of the V-belt and prolongs the service life through structural design. The patent "a conductive glue composition for making V-belts" provides a kind of conductive glue composition for making V-belts. Through the improvement of the formula, the product has electrical and thermal conductivity and anti-static Good fire resistance and long service life. However, the prior art does not provide a V-belt composition formulation that improves the flex resistance and prolongs the service life of the V-belt. Contents of the invention [0003] The object of th...
