Abstract

An anti-ageing rubber material used for elastic vibration isolating element is formed by rubber base material, an anti-aging system, a stuffing system and a sulfurization system, wherein, the rubber base material is natural rubber or blending material mixed by natural rubber and neoprene, wherein, the weight ratio of the neoprene is 10-20 percent; the anti-aging system includes age inhibitor D, age inhibitor 4010NA, age inhibitor AW and paraffine; the stuffing system is one or more of semi-reinforcing carbon black, high wear-resistant carbon black and white carbon black; the sulfurization system includes accelerator M, accelerator TT, accelerator CZ, accelerator NA-22 and sulfur, zinc oxide, light magnesium oxide and stearic acid; the weight ratio of the material formula comprises 100 parts of rubber base, 4-10 parts of anti-aging system in total, 40-80 parts of stuffing system in total; the sulfurization system can adopt various combined proportions. The rubber material has cheap cost and good anti-aging performance, and can give the elastic vibration isolating element low dynamic to static ratio.

Description

Technical areas: [0001] The invention belongs to the technical field of polymer materials and is an anti-aging rubber material used for elastic vibration isolation components and a preparation method thereof. Background technique: [0002] The harm caused by vibration pollution to people has received more and more attention. Among them, vibration and noise pollution in transportation systems have become one of the focuses of attention. Especially in rail transit systems such as subways or light rails, due to the collision between wheels and rails during operation, Shock waves and noise. Shock waves will propagate in tracks, tunnels, soil layers and ground buildings, producing corresponding vibrations, which will have a very adverse impact on surrounding buildings and residents' lives. [0003] A common solution is to apply elastic vibration isolation components, such as track dampers, sleeper boots, ballast pads, rubber bearings, etc., to reduce the support stiffness of the...
