Anti-abrasion and compression-resisting coating

Abstract

The invention provides an anti-abrasion and compression-resisting coating, which is especially designed aiming at a vibration isolation support of an energy dissipation and vibration absorption system of a building. The anti-abrasion and compression-resisting coating is prepared from 2 percent of methyl pyrrolidone, 2 percent of naphtha, 85 percent of polytetrafluoroethene, 8 percent of molybdenum disulfide, 2 percent of methyl isobutyl ketone and 1 percent of xylene. The anti-abrasion and compression-resisting coating can be coated on a sliding seat which is internally arranged in an arc concave surface between an upper disc surface and a lower disc surface of the vibration isolation support; the sliding seat is formed by an upper sliding block and a lower sliding block; the top part of the upper sliding block is an arc convex surface, and the bottom part of the upper sliding block is an arc concave surface; the top part and the bottom part of the lower sliding block are both arc convex surfaces; excellent abrasion resistance and excellent compression-resisting capacity can be obtained, the anti-abrasion and compression-resisting coating can be suitable for energy dissipation and vibration absorption systems of various buildings, and an excellent vibration absorption effect is obtained because the upper disc surface and the lower disc surface of the vibration isolation support slide relative to the sliding seat while an earthquake encounters; meanwhile, the service life can be effectively prolonged, and an excellent industrial utilization value is achieved.

Description

technical field [0001] The invention relates to a wear-resistant and pressure-resistant coating, which is mainly applied to the shock-isolation support of the energy-dissipating and shock-absorbing system of a building. The surface of the seat, in addition to giving it better wear resistance and resistance to heavy pressure, also reduces the friction coefficient between the two, so as to improve its sliding and shock absorption performance in the face of earthquakes, so that the impact of earthquakes on buildings can be reduced. to a minimum. Background technique [0002] Taiwan is located at the junction of the Philippine plate and the Eurasian continental plate. It is an area with frequent earthquakes. In order to avoid catastrophic damage to buildings caused by earthquakes, seismic isolation technology has been introduced into the building structure in the design of various buildings. An energy-dissipating and shock-absorbing system that can effectively isolate earthquak...

Problems solved by technology

[0007] The wear-resistant and pressure-resistant coating of the present invention is mainly to solve the heavy pressure resistance and wear resistance faced between the upper plate surface, the lower plate surface and the sliding seat of the existing shock-isolation bearing under the stress of the earthquake. It is designed to solve the problem, hoping that through the coating of wear-resistant and pressure-resistant coating, its wear resistance and heavy pressure resistance can be significantly improved, so as to give better energy dissipation and shock absorption performance and prolong the service life, and It can appropriately reduce the size of the upper and lower plates of the sliding seat to achieve economic benefits
