Abstract

The invention relates to a nanometer material modified rubber support bass. It is made up of nanometer material modified rubber support and steel plate equipped in it. Its weight copies ratio constituent is that caoutchouc (100 portion); nanometer zinc oxide (2-3); stearic acid (1.5-2.5); accelerant CZ (1-1.5); sulfur (1.5-2); anti-aging agent granule (1-2); anti-aging agent4010NA (1-2); carbon blackN220 (30-35); nanometer calcium carbonate (25-30). The invention improves the compression deformation capability and ageing resistance of the sizing material, prolongs the useful life; it can improve dynamic performance of the production, and avails to improve the service performance.

Description

technical field [0001] The invention relates to a nano material modified rubber bearing. technical background [0002] The main function of the bridge plate rubber bearing is to reliably transmit the upper reaction force to the abutment, and at the same time complete the deformation of the beam structure (horizontal displacement and rotation angle). According to these requirements, the rubber bearing should be designed with sufficient rigidity in the vertical direction to ensure that the bearing has a small deformation under the maximum vertical load; the rubber bearing should have a certain degree of flexibility in the horizontal main direction to adapt to The horizontal displacement of the beam body due to the braking force temperature, the shrinkage of the concrete and the load, etc., and the rubber bearing is also suitable for the rotation of the beam end. According to the shape, it is divided into: a rectangular plate rubber bearing; b circular plate rubber bearing; c ...
