Abstract

The invention discloses a reinforcing filling material of a rubber damping product. The reinforcing filling material comprises white carbon black, calcined kaolin, paraffin oil, zinc oxide, stearic acid, C9 resin, an anti-aging agent Rd, an anti-aging agent 4010 and a coupling agent. The reinforcing filling material is prepared by the steps of high-speed stirring and mixing, heating, low-speed stirring and mixing, cooling, discharging, preparing and the like. The reinforcing filling material has a good damping and reinforcing function; and the filling material is stable in thermal stability and aging resistance, is less affected by air and environment, prolongs the service life of a rubber product, and improves the shock absorption performance; the rubber product can realize good electrical insulation performance of a signal system, adapts to the use of a sleeper rubber shock absorption plate, and provides a wider application foundation.

Description

technical field [0001] The invention relates to the technical field of rubber shock-absorbing products, in particular to a reinforcing filling material for rubber shock-absorbing products. Background technique [0002] Shock-absorbing rubber is used to prevent vibration and shock transmission or buffer vibration and shock strength. Rubber has good damping properties, and the relative value in the elastic range can reach 10%-65%, and its dynamic and static modulus ratio can reach 1.5. About, the elastic deformation of rubber is more than that of metal (mostly more than 10,000 times), while the elastic modulus is much smaller than that of metal (mostly 1 / 700-1 / 4000), and the sound speed of rubber is 10-200m / s, while the sound velocity of steel is 5000m / s, so rubber has good shock absorption, buffering, sound insulation and other functions. [0003] In modern rail transit, in order to effectively reduce the force of the wheel and rail, improve the system's walking function, a...
