Sliding plate for friction pendulum type seismic mitigation and absorption support and preparation method
The invention belongs to the technical field of sliding plates and preparation methods, and discloses a sliding plate for a friction pendulum type seismic mitigation and absorption support, a preparation mold and a preparation method. The sliding plate is mainly and technically characterized by comprising the following materials in parts by weight: 100 parts of polyformaldehyde; 5-30 parts of polytetrafluoroethylene fibers; 1-5 parts of polytetrafluoroethylene micro powder; 2-8 parts of a lubricant; 0.5 to 2 parts of carbon fibers; 0.5 to 4 parts of calcium sulfate whiskers; 0.1 to 1 part of an antioxidant; and 0.1-1 part of a light stabilizer. The polyformaldehyde is used as a main body, the polytetrafluoroethylene exists in the sliding plate in two forms of fibers and powder, the polytetrafluoroethylene fibers play a role in supporting a frame, and the powder polytetrafluoroethylene can form a transfer film in the abrasion process, so that the abrasion of the sliding plate is reduced. The dependence of the existing polytetrafluoroethylene filled modified ultra-high-molecular-weight polyethylene sliding plate on silicone grease is solved, the maintenance difficulty of the supportsliding plate is solved, and meanwhile, the service lifetime of a bridge is prolonged.
本发明属于滑板及制备方法技术领域，公开了一种摩擦摆式减隔震支座用滑板和制备模具及制备方法。其主要技术特征为：包括有下列重量份的材料：聚甲醛100份；聚四氟乙烯纤维5‑30份；聚四氟乙烯微粉1‑5份；润滑剂2‑8份；碳纤维0.5‑2份；硫酸钙晶须0.5‑4份；抗氧剂0.1‑1份；光稳定剂0.1‑1份。由聚甲醛作为主体，聚四氟乙烯是以纤维和粉状两种形态存在于滑板中，聚四氟乙烯纤维起到支撑框架的作用，而粉状的聚四氟乙烯在磨耗过程中可以形成转移膜，降低滑板的磨损磨耗。解决了现有的填充聚四氟乙烯和改性超高分子量聚乙烯滑板对硅脂的依赖性，解决了对支座滑板的养护困难，同时延长了桥梁的使用寿命。
