Problems solved by technology
However, the stiffness is low and the hardness of the rubber is relatively low, which has an adverse effect on rubber creep, strength, and bonding properties with metals
At the same time, due to the low stiffness, the displacement becomes larger under dynamic use conditions, and the rubber at the stress concentration point is broken; in addition, the aging resistance of natural rubber is not good, the modulus loss is large during use, and the rubber creep is serious
In light cases, a new set of mounts needs to be replaced, resulting in a waste of rubber and metal material resources, and in serious cases, it will cause the engine to shift and affect the service life of the powertrain

Abstract
The invention discloses a rubber composition of automobile motor suspension. The composition is prepared from, by weight, 2.5-3.5 parts of physical antiager, 7-10 parts of activating agent, 5-8 partsof plasticizer, 0.6-1 part of vulcanizing agent, 100 parts of white carbon black wet natural rubber, 1.5-2.5 parts of diaryl secondary amine antiager, 2-3 parts of para-phenylenediamine derivative antiager, 18-25 parts of reinforcing agent, 1.5-2 parts of assistant crosslinker and 1.5-1.8 parts of accelerator. The rubber composition of the automobile motor suspension has the advantages that the high temperature resistance and heat resistance performance is good, and dynamic modulus loss is low; physical property change of a rubber material is little after aging, the strength retaining rate ishigh, and permanent deformation through high-temperature compression is good; the produced motor suspension has low stiffness and good NVH effect, high-temperature creep and high-temperature fatigue performance, and the motor suspension is at the top of the industry and recognized by clients at home and abroad.
Description
technical field [0001] The invention relates to a rubber composition for automobile engine suspension, which is used for making automobile engine suspension main springs and suspension components, and belongs to the technical field of rubber. Background technique [0002] The main function of the automobile engine mount is to support the mass of the engine assembly, and to avoid excessive displacement of the power assembly and interference with other components under loads such as starting, shifting, acceleration, braking, steering, and impact on uneven roads . As an important part connecting the powertrain and the body, the suspension system not only supports and stabilizes the engine, but also isolates the vibration generated by the engine from being transmitted to the frame and cab, reducing vibration and noise. Therefore, the suspension plays a very important role in the NVH performance of the vehicle, and it needs to have good vibration isolation performance. Because ...
