Rubber composition, aging-resistant rubber product using the same

A rubber support, wherein, a rubber compound used for the rubber support comprises a rubber composition comprising a rubber matrix and essential components, wherein the rubber matrix comprises, based on 100 parts by weight of the rubber matrix, a branched polyethylene with a content represented as A, in which 0<A≤100 parts, and an ethylene-propylene rubber with a content represented as B, in which 0≤B<100 parts;

• and based on 100 parts by weight of the rubber matrix, the essential components comprise 1.5-10 parts of a crosslinking agent, 30-200 parts of a reinforcing filler, and 5-250 parts of a plasticizer, wherein the branched polyethylene comprises an ethylene homopolymer having a degree of branching of not less than 50 branches/1000 carbon atoms, a weight average molecular weight of not less than 50,000, and a Mooney viscosity ML(1+4) at 125° C. of not less than 2;
• and
• wherein either:
• the rubber support is a plate-type rubber support of bridge and comprises a steel plate and a rubber sheet, wherein the rubber sheet comprises the rubber compound;
• the rubber support is a basin-type rubber support and comprises a rubber bearing plate comprising the rubber compound;
• or
• the rubber support is a vehicle shock-absorbing support.
