A kind of double short fiber reinforced rubber for automobile engine mount and its preparation method

Abstract

The invention discloses a double-short-fiber-reinforced rubber for automobile engine mounts. Through the mixed use of pre-treated aramid short fibers and pre-treated nylon short fibers, the aramid short fibers can be used to easily reinforce the hardness mold of the mixed rubber. The advantages of the quantity, and the advantage of using nylon short fibers to easily reinforce the strength of the mixed rubber, reducing the use of traditional reinforcing carbon black, increasing the rubber content of the rubber elastomer in the mixed rubber, thereby improving the resilience of the mixed rubber, Then optimize its cushioning performance; at the same time, the strength of the vulcanized rubber after high temperature aging resistance can be improved through short fiber reinforcement, and its performance under high temperature conditions can be optimized. The invention also discloses a preparation method of double short fiber reinforced rubber for automobile engine suspension.

Description

technical field [0001] The invention relates to a double-short-fiber-reinforced rubber for automobile engine mounts and a preparation method thereof. Background technique [0002] The rubber engine mount in the vehicle mainly plays the role of buffering engine vibration, protecting other parts of the powertrain, and reducing engine resonance noise. In order to play a good role in buffering vibration and reducing noise, it is required to reduce the content of fillers (carbon black, calcium carbonate, etc.) in the rubber compound used for engine mounts, increase the rubber content, and make it have higher resilience; However, if the use of fillers is reduced, the strength of the vulcanized compound will inevitably be reduced. [0003] At the same time, the rubber used for engine mounts has to resist the high temperature of the engine as high as 90°C, while the traditional carbon black reinforced rubber compounds lack heat resistance. [0004] Therefore, it is necessary to de...
