Abstract

The invention relates to a durable lubricating and friction-reducing slide plate for a bridge support. The composite slide plate is formed by compounding a wear-resistant material and a slow-release friction-reducing material, the wear-resistant material is a non-metal wear-resistant sliding plate formed by a polymer-based polymer material, a pit or a groove is formed in the surface of the non-metal wear-resistant sliding plate, and the slow-release friction-reducing material is formed in the pit or the groove in the surface of the non-metal wear-resistant sliding plate; the slow-release friction-reducing material is compose of a carrier material, an adsorption material, a lubricating material and a stabilizer; the slow-release friction-reducing material comprises the following componentsin percentage by weight of 30%-60% of the carrier material, 5%-20% of the adsorption material, 10%-40% of the lubricating material and 10%-20% of the stabilizer. The composite sliding plate has the characteristics of strong bearing capacity, small friction coefficient, excellent wear resistance and long effective lubrication time.

Description

technical field [0001] The invention belongs to the field of polymer material development for bridge supports, and in particular relates to a long-lasting lubricating anti-friction slide plate for bridge supports. Background technique [0002] As the "joint" part connecting the bridge and the pier, the bridge bearing not only bears the load of the bridge structure above the bearing, but also has the functions of sliding and rotating. The sliding and rotating functions of the bridge are realized by the plane friction pair and the spherical friction pair of the support. In order to reduce the friction resistance during the sliding and rotating process of the bridge, the friction pair of the bridge support adopts a non-metallic sliding plate and a metal with a good surface finish. Surface composition, and apply silicon grease as lubricating grease between the non-metallic slide plate and the metal counter-friction surface. At present, the friction pair of the support uses 5201...
