The rubber cushion plate is prepared from the following raw materials of maleic anhydride grafted ethylene-propylene-diene monomer, phenylene ether silicon rubber, maleic resin, mixed acid modified bone glue, pearlite, rectorite powder, halloysite clay, China hemp fiber, a compound coupling agent, a compound accelerant and a compound anti-aging agent. The rubber cushion plate disclosed by the invention has excellent mechanical property, ageing resistance, hydrophobic oil resistance, high and low temperature resistance, wear resistance and the like; the application field and the application prospect of the rubber cushion plateare greatly improved, an active demand of existing and later market and industry for high-performance rubber cushion plate can be met, and social development is promoted.

Description

technical field [0001] The invention relates to the technical field of rubber pad materials, in particular to a high-performance composite rubber pad and its application. Background technique [0002] With the rapid development of high-speed railways in recent years, since the opening of intercity railways in 2008, intercity trains have become a normal means of transportation. Based on the advantages of good smoothness of ballastless track, less maintenance during service life, long service life, and allowing speed increase in the future, ballastless track is used in modern high-speed railways. However, the ballastless track also has the disadvantage of high rigidity, which can easily cause the train to detach from the track and cause driving hazards. In order to make up for this defect, an elastic backing plate is specially introduced into the ballastless track. Existing elastic pads are generally made of polymer materials such as rubber foamed elastomers and microporous p...
