Embodiment 1

[0022] A high temperature fatigue resistant rubber composition for automotive engine mounts, comprising the following components in parts by weight:

[0023] Table 1

[0024]

[0025]

[0026] The preparation of above-mentioned composition adopts internal mixer mixing, and its steps are as follows:

[0027] Internal mixer mixing: raise the temperature of the internal mixer to 90-110°C, put CV-60 natural rubber into the internal mixing chamber and knead for 60s, lift the top bolt to add active agent, stearic acid and anti-aging agent, etc. For a good section of fine material, add reinforcing agent and plasticizer after 90s, lift the top bolt to clean the machine and the carbon black on the top bolt after 180s, put down the top bolt and continue banburying for 60s, then discharge the glue and put it on the open mixer Roll out the sheet, cool it and park it for at least 12 hours, put a piece of mixed rubber into the internal mixer to soften for 30s, add crosslinking agent ...

Abstract

The invention discloses a rubber composition for an automobile engine mounting system. The rubber composition comprises the following components in parts by weight: 100 parts of natural rubber, 3.3-4.3 parts of a p-phenylenediamine anti-aging agent, 2-3 parts of a di-hydro-quinoline anti-aging agent, 2-3 parts of a physical anti-aging agent, 2-4 parts of a plasticizer, 24-28 parts of a reinforcing agent, 5-8 parts of an activator, 1-1.5 parts of stearic acid, 5-8 parts of a cross-linking agent, 2-2.5 parts of a vulcanizing agent and 1-1.5 parts of an accelerant. Due to introduction of a functional high-temperature-resistant cross-linking agent HEM-100, the thermal resistance can be improved by changing bonds among molecules, and on premise that a relatively low dynamic-static ratio is ensured, the dynamic fatigue resistance of rubber under a high temperature can be improved.

Description

technical field [0001] The invention relates to a high-temperature fatigue-resistant rubber composition for automobile engine mounts, which is used for making automobile engine mounts and belongs to the technical field of rubber. Background technique [0002] Nowadays, automobile factories at home and abroad have very high requirements for the service life of rubber shock absorbing products. The engine mount is installed between the engine and the chassis of the car to support the powertrain and isolate (reduce) the transmission of engine vibration energy to the chassis. The purpose of the vibration isolation system. It can not only alleviate the impact of the force transmitted from the ground on the body, improve the comfort of the ride, but also have the function of controlling the relative movement and displacement of the powertrain, and can overcome and balance the reaction force generated by the maximum torque output or emergency braking. and inertial force to avoid mu...
