Shock-absorbing and lubricating coating for buildings and preparation method and applying method of shock-absorbing and lubricating coating

Abstract

The invention provides a shock-absorbing and lubricating coating and a preparation method and an applying method of the shock-absorbing and lubricating coating. The shock-absorbing and lubricating coating comprises the following materials in parts by weight: 10-25 parts of thermoplastic acrylic resin, 10-15 parts of EVA resin, 1-10 parts of epoxy resin, 1-10 parts of phenolic resin, 4-23 parts of molybdenum disulfide, 0.01-0.3 parts of an organosilan coupling agent and 35-55 parts of a mixed solvent, wherein the mixed solvent comprises the following materials in parts by weight: 23-33 parts of a plasticizer, 0.1-20 parts of a foamer, 0.1-0.8 part of a cross-linking agent, 10-17 parts of a thixotropic agent, 10-28 parts of acetone, 10-30 parts of methyl benzene and 20-35 parts of ethylene glycol ethyl ether. The shock-absorbing and lubricating coating is favorable in adhesion, wear resistance, moisture and heat resistance and flexibility, high in impact strength and relatively low in friction coefficient; besides, sustained pressure of 100 MPa or above can be borne, the stretching and shearing strengths are excellent, and certain stability is realized; curing is completely free of adhesion, surface curing and internal curing are not different, effective sliding of a shock-absorbing support part for buildings is realized under the action of transverse seismic waves, and the shock-absorbing and shock-resisting effects are achieved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a shock-absorbing lubricating coating for buildings and a preparation and coating method thereof. Background technique [0002] Earthquake resistance of buildings is the basic requirement of modern building construction, and it is also closely related to everyone's life safety. At present, the general practice is to attach a sliding support structure to the base of the building to effectively reduce or prevent the damage of the building under the action of transverse seismic waves, and achieve the effect of shock absorption and shock resistance. Therefore, the interface of such support structures must not only have extremely high compressive resistance, but also have a low and stable coefficient of friction and outstanding wear resistance. Since the supporting structure of the building is underground all the year round, it is subjected to strong pressure loads for a long time, and it is ...

AI Technical Summary

Problems solved by technology

Since the supporting structure of the building is underground all the year round, it is subject to strong pressure load for a long time, it is not easy to replace and must have a long service life, so the conventional lubricating material covering the interface of the supporting structure is difficult to meet such requirements

[0003] In recent years, the relatively rapid development of solid lubrication technology has achieved remarkable results in many fields, and it is mostly used in high-tech fields such as aerospace and navigation; although this lubrication technology can achieve effective sliding of supports under lateral vibration conditions, However, due to its high cost, it is rarely used in ordinary construction fields.
