Problems solved by technology

In order to reduce the temperature of the transmission environment, the transmission belt is placed in a liquid-phase environment to overcome it, which is called a wet transmission belt. This structure will inevitably make the transmission complex in structure, large in size and high in energy consumption.
At the same time, the reinforcing cords in waste transmission belts are generally discarded, which pollutes the environment and wastes materials.

Abstract

The present invention discloses a short fibre / rubber composite for manufacturing driving belt, comprising hydrogenized nitrile rubber, styrene butadiene rubber, short fibre made from the reinforcement cord of the worn-out driving belt, chloroprene rubber, vulcanizing agent, coupling agent and phenol-formaldehyde resin. The driving belt of the invention made from the composite has a good thermal endurance, self- lubricity, oil resistance and durability. And the reinforcement cord and the special binding agent are unused to manufacture the driving belt, which economizes the cost of manufacture, prolongs the service life of the driving belt greatly, and raises the drive efficiency.

Description

technical field [0001] The invention relates to a rubber composite material, in particular to a short-fiber rubber composite material used for manufacturing transmission belts. Background technique [0002] The transmission belt is the core connecting part of the electromechanical equipment. It has a wide variety of types and a wide range of uses. Most of the transmission methods in the prior art are still based on rubber transmission belts, and its development is still expanding. Transmission belts can basically be divided into two categories: friction transmission and meshing transmission. In the prior art, a transmission belt includes a rubber belt body, a reinforcing cord, and an adhesive for bonding the rubber belt body and the reinforcing cord. Due to the inevitable frictional heat generation in the transmission process, the belt body will be damaged to varying degrees, and the transmission belt that relies on friction transmission is also prone to slipping according...
