technical field

The invention relates to a rubber performance testing system and a rubber performance testing method.

Background technique

With the rapid development of the automobile industry, in order to meet the needs of consumers to improve the safety, comfort and economy of radial tires, since the 1970s, steel cords have been used as important skeleton materials for tire carcass and belt layers. . Due to the large deformation, low elastic modulus and obvious viscoelastic hysteresis of rubber, whether steel cords can be well bonded to rubber has become a key factor determining the service life, durability and safety of tires. The test methods for the bonding performance of vulcanized rubber/steel cords are mainly EC method and ASTM method. The computer test system is used to control factors such as tensile speed and displacement. The operation is relatively simple, but the test process is limited to the measurement of static bond strength. , and the working state of the tire is mainly subjected to cyclic loads for a long time, the static method cannot simulate the real state of the tire during use, so the characterization of the bonding performance of the vulcanized rubber/steel cord under the cyclic load during the running of the tire Has become the focus of tire research workers.
