Abstract

The invention discloses a shock absorption support composite material for high-cold, high-altitude and high-ultraviolet regions and a preparation method thereof. The composite material comprises a rubber component, a liquid farnesene polymer or a liquid farnesene copolymer, liquid polybutadiene or a liquid polybutadiene copolymer, trans-polyisoprene, carbon black, nano titanium dioxide, a physicalprotective agent, a chemical anti-aging agent, an anti-ultraviolet agent, tackifying resin, fiber, an activating agent, an accelerant and a vulcanizing agent. A shock absorption support prepared fromthe composite material provided by the invention has vertical rigidity, equivalent horizontal rigidity and damping ratio all meeting the requirements of actual bridge application and has good comprehensive shock absorption effect. The selected components can reduce the energy consumption of rubber processing, also have good compatibility with a rubber matrix, and participate in the cross-linkingreaction during vulcanization, also can improve the mechanical properties and low temperature resistance of the formula, and have good bonding performance with a steel plate, thus meeting the requirement of large deformation.

Description

technical field [0001] The invention relates to a shock-absorbing support composite material and a preparation method thereof, in particular to a shock-absorbing support composite material suitable for high-cold, high-altitude and high-ultraviolet regions and a preparation method thereof. Background technique [0002] At present, the use of shock absorbing materials such as bridges, tunnels and special road sections, bridge bearings, waterstops, road expansion joints, etc. is extremely common. In the plateau climate and low temperature areas, the existing conventional products are difficult to meet the needs of use, which greatly limits the construction of expressway networks in the plateau and low temperature areas in my country. The construction of expressway network in Tibet, Qinghai and other regions is of great strategic significance to my country. In order to solve the problems of high cold resistance, UV resistance and high altitude resistance of highway bridges, it is...
