Abstract

The invention discloses an environment-friendly shock-isolating rubber support. The environment-friendly shock-isolating rubber support comprises the following raw materials in parts by weight: 90-100 parts of chloroprene rubber, 40-45 parts of polyacrylate rubber, 20-28 parts of butyl rubber, 140-150 parts of a filling material, 4-8 parts of 2, 2-bis-(t-butylperoxy) propane, 0.4-0.8 part of zinc oxide, 2-6 parts of a vulcanization promoter M, 6-10 parts of a plasticizer and 3-5 parts of an antioxidant. The environment-friendly shock-isolating rubber support provided by the invention not only has very high elasticity after vulcanization so as to meet a shock absorbing function, but also has very high size stability, good fatigue resistance, long-term loading capacity and very good creep resistance, and does not decompose out carcinogenic substances at a vulcanization temperature, and thus does not cause a potential threat to human health.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an environment-friendly shock-isolation rubber bearing. Background technique [0002] The environmental protection shock-isolation rubber bearing is a bridge bearing product formed by inlaying, bonding and vulcanizing multi-layer rubber and thin steel plate. This type of rubber bearing has sufficient vertical stiffness to withstand vertical loads, and can reliably transmit the pressure of the superstructure to the abutment; in addition, it has good elasticity to adapt to the rotation of the beam end, and has a large shear deformation To meet the horizontal displacement of the superstructure. At present, the environmentally friendly shock-isolation rubber bearings used in China still pollute the environment after being discarded, and have poor fatigue resistance, and the creep resistance performance cannot meet the demand, which needs to be solved urgently.
