Abstract

The invention discloses a high-temperature resistance low-dynamic-rate rubber material for suspension and a preparation method thereof. The high-temperature resistance low-dynamic-rate rubber material comprises 70 to 120 parts of chloroprene rubber adhesive, 30 to 100 parts of reinforcing agent, 0.1 to 5 parts of accelerator, 2 to 14 parts of active agent, 0.1 to 7 parts of anti-aging agent and 5 to 14 parts of plasticizer. The preparation method comprises the following steps of: placing the raw materials into an internal mixer to obtain synthetic rubber; after carrying out uniform heat bodying on the synthetic rubber qualified by detection, carrying out extrusion forming and then injecting a formed rubber strip into a die in vulcanization equipment to carry out vulcanization; and trimming the vulcanized product and checking the size and appearance to obtain the qualified finished product. The high-temperature resistance low-dynamic-rate rubber material for suspension prepared according to the formula and the preparation method which are disclosed by the invention has excellent performances of high-temperature resistance, oil resistance, long service life, lower production suspension dynamic rate and the like.

Description

technical field [0001] The invention relates to a rubber material, in particular to a high temperature resistant low dynamic ratio rubber material for suspension and a preparation method thereof. Background technique [0002] The engine is a core component of the automobile, and it is also one of the main sources of automobile vibration. Reducing engine vibration and improving its life is one of the main topics of automobile research. Among them, the engine mount has a good effect on reducing vehicle vibration and noise. With the needs of the current technological development, the product's high temperature resistance and low dynamic ratio have become an important standard for product quality. Most of the current automobile shock absorber materials are natural rubber, which has poor heat resistance and high dynamic magnification, which cannot meet the requirements of heat resistance and low dynamic magnification. [0003] The function of the rubber mount: (1) Fix and s...
