Embodiment 1
[0032] A rubber composition for an automobile suspension bushing, comprising the following components in parts by weight:
[0033]
[0034] The preparation of above-mentioned composition can adopt internal mixer mixing, and its steps are as follows:
[0035] (1) Active agent, stearic acid, p-phenylenediamine antioxidant, phosphite ester antioxidant, ketamine antioxidant, physical antioxidant, resin, tackifier and anti-vulcanization reducing agent are grouped in parts by weight Allocated as a fine material for use;
[0036] (2) Raise the temperature of the internal mixer to 90-110°C, put the plasticized Vietnam SVR-3L and butadiene rubber into the mixing chamber for 60 seconds, and then lift the top bolt to add the prepared in step (1) For fine materials, add reinforcing agent and plasticizer after 60s, 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 glue and roll o...

Abstract
The invention provides a rubber composition used for an automobile suspension bushing. The composition comprises 80-90 parts of natural rubber, 10-20 parts of butadiene rubber, 6-8 parts of activatingagent, 1-2 parts of stearic acid, 1.5-2.5 parts of para-phenylenediamine antiager, 1.5-3.5 parts of phosphite ester antiager, 1.5-2.5 parts of keto-amine antiager, 2-3 parts of physical antiager, 50-70 parts of reinforcing agent, 10-22 parts of plasticizer, 2.0-3.0 parts of resin, 2.0-3.0 parts of tackifier, 2.0-3.0 parts of vulcanizing agent, 1.0-2.0 parts of accelerator and 1.0-2.0 parts of anti-sulphuration reducing agent. The invention further provides the preparation method of the rubber composition. The rubber composition has good mechanical performance and fatigue resistance performance, and not only is the adhesive performance effectively improved, but good heat resistance performance is provided; the rubber composition is used for the automobile suspension bushing and maintains good adhesive performance and low stiffness loss after being used for a long time.
Description
technical field [0001] The invention relates to a rubber composition for automobile suspension bushings, which is used for making automobile suspension bushes and belongs to the technical field of rubber. Background technique [0002] With the continuous improvement of people's environmental and health awareness, the comfort and sound quality of vehicles have attracted more and more attention. Vehicles with high noise and vibration not only cause sound pollution to the surrounding environment, but also endanger the health of drivers and passengers. In the highly competitive automotive market, reducing noise levels has become a new focus of competition and direction of technological development. Since the advent of the bonding technology of rubber and metal parts in the 20th century, its vibration isolation and noise reduction characteristics have attracted the attention of the academic community, and have been widely used in the automobile industry, directly affecting the N...
