Sliding plate for seismic mitigation and isolation support and preparation method
The invention belongs to the technical field of sliding plates and preparation methods, and discloses a sliding plate for a seismic mitigation and isolation support and a preparation method. The sliding plate is mainly and technically characterized by comprising a sliding plate body; the sliding plate body comprises the following materials, by weight: 100 parts of ultra-high molecular weight polyethylene, 10 to 60 parts of polytetrafluoroethylene fiber, 0.5 to 5 parts of a lubricant, 0.5 to 5 parts of carbon fiber, 0.5 to 4 parts of calcium sulfate whisker, 0.1 to 2 parts of a coupling agent,and 0.1 to 2 parts of a compatilizer. The sliding plate takes ultra-high molecular weight polyethylene as a main body; the polytetrafluoroethylene exists in the sliding plate in a fibrous form; the polytetrafluoroethylene fiber is cut off and falls off through the friction force between the support and the sliding plate; the fallen polytetrafluoroethylene fibers and the lubricant form a lubricating film on the surface of the sliding plate under the action of pressure, the lubricating film is attached to the surface of ultra-high molecular weight polyethylene to play a role in reducing abrasionand consumption, the activated carbon has very strong adsorption performance, can adsorb part of the lubricant and play a role in slow release, and the service life of a bridge is prolonged.
本发明属于滑板及制备方法技术领域，公开了一种减隔震支座用滑板及制备方法。其主要技术特征为：包括滑板本体，所述滑板本体包括有下列重量份的材料：超高分子量聚乙烯100份；聚四氟乙烯纤维10‑60份；润滑剂0.5‑5份；碳纤维0.5‑5份；硫酸钙晶须0.5‑4份；偶联剂0.1‑2份；相容剂0.1‑2份。该滑板以超高分子量聚乙烯为主体，聚四氟乙烯是以纤维状存在于滑板中，通过支座与滑板之间的摩擦力将聚四氟乙烯纤维切断、脱落，脱落的聚四氟乙烯纤维和润滑剂在压力作用下，在滑板表面形成润滑膜，并附着在超高分子量聚乙烯表面，起到减磨减耗的作用，活性炭具有很强的吸附性能，可以吸附部分润滑剂，并起到缓慢释放的作用，延长了桥梁的使用寿命。
