Problems solved by technology

[0002] The engine mount not only absorbs vibrations and generates heat through internal friction like other bushings, but it is also adjacent to the engine, and the temperature can reach up to 100 degrees Celsius. Therefore, the rubber material in the engine mount must be in a high temperature state for a long time, and the rubber material is Poor conductor of heat, the thermal conductivity of natural rubber is lower than 0.2W / (m K), heat will accumulate inside the rubber matrix, and it is difficult to disperse, while traditional fillers can only increase the mechanical properties of rubber composites, And increase the damping, but it does little to help the heat dissipation. Therefore, under the high temperature that is difficult to derive, the tendency of the natural rubber macromolecular chain in the engine mount to break will increase, and the aging resistance and fatigue resistance will decrease sharply. Negatively affect the service life of the engine mount and the safety performance of the vehicle
