Abstract

The invention discloses a shock-absorbing rubber block which is prepared from butadiene styrene rubber, EPDM, butadiene rubber, cinnamyl aldehyde, coumarone, graphite, titanium dioxide, an anti-ageing agent, a cross-linking agent and a vulcanizing agent. A preparation method includes the steps that all the components are added into a mixing container, the mixing container is placed in an ultrasonic instrument for mixing for 5-10 min, and the ultrasonic instrument is shut off; the mixing container is transferred into a vulcanizing machine, vulcanizing temperature is set to be 140-155 DEG C, vulcanizing is conducted for 15-20 min, and vulcanizing forming, cutting, trimming and packaging are carried out.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a production method of shock-absorbing rubber blocks. Background technique [0002] Rubber products are widely used in all aspects of industry or life. Rubber has both high elastic state and high viscous state, which makes it unparalleled in buffering, shock absorption and dynamic sealing. Rubber parts are widely used to isolate vibration and absorb shock. However, with the increase of the speed of the railway locomotive, the dynamic effect on the line increases sharply, causing severe wear and tear on the line, tires and components of the locomotive running part, and the requirements for the shock resistance of various parts of the railway locomotive are getting higher and higher. Contents of the invention [0003] One of the objects of the present invention is to provide a shock-absorbing rubber block, which can solve the problem of poor shock resistance of existing rubber bl...
