A thick build type impact-resistant and wear-resistant elastic coating for deflecting structures and its application method

Abstract

The invention discloses a thick-paste impact-resistant and wear-resistant elastic coating for a deflecting flow structure and an application method thereof. The thick-paste impact-resistant and wear-resistant elastic coating mainly comprises a component A, a component B and a component C, wherein the ratio of the component A to the component B to the component C in parts is (50-80):(25-40):(0.75-1.2); the component A mainly comprises carborundum, washed-out sand and wear-resistant glazed hollow beads; the component B mainly comprises single-component polyurea, a toner and thixotropic powder; and the component C is a quick-setting interface treating agent. The coating has a water sealing effect, freeze-thaw erosion of concrete caused by a water seepage defect can be avoided, the thick-paste impact-resistant and wear-resistant elastic coating is convenient to construct, good in environmental protection property, long in ageing and high in deformability and the harm caused by a concrete crack can be eliminated. The deflecting flow structure coated with the material has anti-scouring and wear-resistant effects.

Description

technical field [0001] The invention relates to a building material, in particular to a thick paste type impact-resistant and wear-resistant elastic coating for deflecting structures and its application method. Background technique [0002] In the deflected flow structure of hydraulic structures, under normal circumstances, when high-speed water scours the concrete surface, the concrete will often undergo erosion and cavitation damage, and when the flowing water engulfs a large amount of sediment, the concrete surface will also undergo abrasion. And collision damage, these destructive forces are huge, often causing a large number of denuded areas on the concrete surface of this part, and some even lead to the exposure and corrosion of the internal steel bars of the concrete. Therefore, it is necessary to use a thick paste type, anti-scouring, anti-wear, reduce impact damage, have a certain elastic effect, and high durability coating. This kind of coating should have the cha...
