Abstract

The invention relates to a method and a tester for testing a dynamic adhesive retention force of rubber and a steel wire. The testing method comprises the following steps: applying a dynamic force to a vulcanized sample of the rubber and the steel wire by virtue of a wave-type mould, and then measuring a residual adhesive drawing force of the rubber and the steel wire so as to represent the magnitude of the adhesive retention force of the rubber and the steel wire under a dynamic condition. The tester comprises a mainframe, a drive system, a measurement control system and a safety protection device. The wave-type mould is used for applying the dynamic force to the vulcanized preparation sample of the rubber and the steel wire.

Description

technical field [0001] The invention relates to the field of rubber, in particular to the field of rubber detection. The invention relates to a method and a testing machine for testing the dynamic adhesive retention force of rubber and steel wire. Background technique [0002] For radial tires, the bonding performance of rubber to steel wire is very important for its service life. The bonding properties of rubber to steel wire mainly include static and dynamic bonding. At present, most researchers have discussed the bonding of rubber and steel cords under static conditions, but few consider the bonding of rubber and steel cords under dynamic conditions. The initial bond strength between rubber and steel cords is important, but only the retention of this bond strength during dynamic use of the tire is truly valuable data. Therefore, the rubber-steel wire dynamic bonding performance is a key factor to ensure the driving safety of tires. This performance depends on the fati...
