The invention relates to a rubber composition. The rubber composition is prepared from the ingredients in parts by mass: 80-120 parts of crude rubber, 1-5 parts of peroxide initiator, 2-15 parts of bridging agent, 0.1-1 part of free-radical absorption and release regulator and reinforcing and anti-aging agents, wherein the crude rubber comprises any one to any three of polybutadiene rubber, natural rubber and styrene-butadiene rubber and accounts for 70 percent or more of mass of the crude rubber. According to the rubber composition and the application thereof, a formula of the rubber composition and adjuvants for product cross-linking and the like is provided, so that the requirements of a technical scheme for representatives, i.e., tires, shoe materials and wear resisting plates on good properties and good industrial adaptability effect can be met; cost and environmentally-friendliness can be taken into account simultaneously.
