Abstract

The invention discloses a connecting plate as well as a preparation method and an application thereof. The connecting plate is prepared from components of raw materials in parts by weight as follows: 100 parts of chloroprene rubber, 80-100 parts of carbon black, 8-12 parts of a high / low-temperature-resistant plasticizer, 3-6 parts of a heat-resistant agent, 2-3 parts of an ozone-resistant agent and 5.5-6 parts of a vulcanizing agent. The connecting plate adopts the components of raw materials including the chloroprene rubber with better lubricating grease resistance and higher damping performance, natural gas semi-reinforcing carbon black, the high / low-temperature-resistant plasticizer, the ozone-resistant agent and the heat-resistant agent consisting of substituted diphenylamine, phenyl naphthylamine and p-phenylenediamine derivatives and the like, and the cooperation relation of all the components of raw materials is regulated, so that the prepared connecting plate has excellent high-temperature resistance, ozone resistance, lubricant medium resistance and better damping performance.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and relates to a connection plate, its preparation method and application, in particular to a connection plate with high temperature resistance, ozone resistance and grease resistance, its preparation method and its use as an adapter plate. Background technique [0002] Electric Power Steering (EPS) is a power steering system that directly relies on the motor to provide auxiliary torque. Compared with the traditional hydraulic power steering system HPS (Hydraulic PowerSteering), the EPS system has many advantages. EPS is mainly composed of torque sensor, vehicle speed sensor, electric motor, deceleration mechanism and electronic control unit (ECU). [0003] With the advancement of society and the improvement of people's living standards, people's requirements for the comfort of cars are also getting higher and higher. When the traditional electric power steering gear directly collides wi...
