Problems solved by technology
[0004] Although traditional natural rubber and butadiene rubber have excellent fatigue resistance, they are very poor in high temperature resistance and ozone resistance. The ozone cracks in the process are very obvious, and the deformation is large, which can no longer meet the requirements of modern vehicles.

Embodiment 1
[0026] This example provides a rubber compound for a dynamic shock absorber assembly. The components of the rubber compound include: 100-150 parts of oil-extended EPDM rubber, 5-8 parts of inorganic active agent, organic active agent 1-3 parts of paraffin, 1-3 parts of paraffin, 1-2 parts of heat stabilizer, 1-3 parts of anti-fatigue agent, 10-30 parts of high wear-resistant reinforcing material, 50-80 parts of semi-reinforcing material, inert filling 40-60 parts of material, 80-100 parts of softener, 0.5-1.5 parts of vulcanizing agent, and 2-3 parts of vulcanizing aid.
[0027] The oil-filled EPDM rubber has low viscosity and high plasticity, which is very beneficial to the processing technology of the rubber material; the rubber material of the dynamic shock absorber component in this example has the advantages of high damping, fatigue resistance and high temperature resistance.
[0028] The heat stabilizer described in this example is preferably heat stabilizer HS-80. The ...
Embodiment 2
[0039] This example also provides a kind of preparation method of above-mentioned sizing material, comprises the following steps:
[0040] In the masticating step, put the oil-filled EPDM rubber in the internal mixer for 5-7 minutes, pass through the open mixer 2-3 times, mix evenly, and park for more than 4 hours;
[0041] In the mixing step, put the weighed raw rubber into the internal mixer together, pressurize for 3-5 minutes, put in the small material and pressurize for 1-2 minutes, add the large material and half of the softener and pressurize for 2 -3 minutes, add half of the softener and pressurize for 2-3 minutes, remove the glue, and park the lower sheet of the open mill at 10-12mm for more than 4 hours; wherein, the temperature of the internal mixer is kept at 130°C-140°C;
[0042]In the vulcanization step, put the mixed rubber obtained in the mixing step into the internal mixer and pressurize it to soften for 2~3 minutes. ~3 times; then put the rubber material int...

Abstract
The invention provides a sizing material of a dynamic shock absorber assembly and a preparation method thereof. The sizing material of the dynamic shock absorber assembly comprises the following components in parts by weight: 100-150 parts of oil filled ethylene propylene diene monomer, 5-8 parts of inorganic activator, 1-3 parts of organic activator, 1-3 parts of paraffin, 1-2 parts of heat stabilizer, 1-3 parts of antifatigue agent, 10-30 parts of highly wearproof reinforcing material, 50-80 parts of semi-reinforcing material, 40-60 parts of inert filling material, 80-100 parts of softener, 0.5-1.5 parts of vulcanizing agent and 2-3 parts of vulcanizing additive. The sizing material of the dynamic shock absorber assembly is excellent in damping capacity, outstanding in durability and excellent in high temperature resistance.
Description
technical field [0001] The invention relates to a rubber material, in particular to a rubber material for a dynamic shock absorber assembly, and to a preparation method of the rubber material. Background technique [0002] Along with the rapid development of high-performance technology in the automobile manufacturing industry, the development of automobile technology seeks the economical use of automobiles on the one hand, and at the same time improves the comfort and safety of automobiles. This puts forward higher requirements on the rubber damping components from the perspective of vibration reduction, noise, comfort and driving stability. [0003] Since the vibration-damping rubber is used under dynamic conditions, its aging (oxygen aging, ozone aging, and fatigue aging) is much more serious than static aging. The aging factors not only act alone, but also affect the vibration in various coupling forms. The effect of rubber, such as mechanical factors (load, vibration co...
