Embodiment

[0028] According to the composition ratio in Table 1, the production of rubbers for automobile engine shock absorbers in Examples 1-6 was carried out.

[0029] Manufacture the EPDM rubber for automobile engine shock absorber of the present invention according to the following steps:

[0030] (1) Preparation of materials: According to the ingredients and proportions in Table 1, EPDM rubber, carbon black, softening plasticizer, active agent zinc oxide, and stearic acid were weighed and mixed to form ingredient A, and vulcanizing agent Weigh to form ingredient B;

[0031] (2) The first mixing: Put ingredient A into the internal mixer for 60-90 seconds, lift the hammer to clean, then press the hammer to mix for 60-90 seconds, lift the hammer to clean again (temperature 140-150°C), and then press the hammer Mix for 60-80 seconds and unload (temperature 150-170°C) to the cutting machine to discharge the sheet to make rubber compound A;

[0032] (3) The second mixing: Put the mixed...

Abstract

The invention discloses an ethylene propylene diene rubber for absorbing the shock of an automobile engine. The ethylene propylene diene rubber for absorbing the shock of the automobile engine is composed of, by weight, 44-50% of ethylene propylene diene rubber, 35-41% of carbon black, 5-10% of a softening and plasticizing agent, 2.5-3% of an active agent and 2.2-2.5% of a vulcanizing agent. The ethylene propylene diene rubber for absorbing the shock of the automobile engine in the invention has the characteristics of high strength, resistance to high temperature aging and low deformation in high temperature compression in a use environment, and is long in service life.

Description

technical field [0001] The invention belongs to the field of rubber, and in particular relates to an ethylene-propylene-diene rubber for automobile engine shock absorption and a preparation method thereof. Background technique [0002] When the automobile engine is working, vibration will be generated due to the reciprocating motion of the piston, cylinder combustion and its moving parts. If the engine is directly connected to the chassis, the chassis will also vibrate, affecting the handling and comfort of the car. Therefore, shock-absorbing rubber products should be installed between the car engine and the chassis, so that the vibration of the engine can be transmitted to the chassis as little as possible, and the elastic deformation of the rubber products can be used to absorb the vibration generated by the engine and reduce noise. [0003] According to the analysis of the China Association of Automobile Manufacturers, my country's automobile production will maintain a s...
