Problems solved by technology

[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 impact damage, these damage force is huge, often cause a large number of denuded areas on the concrete surface of this part, and some even lead to the exposed and corroded steel bars inside the concrete

Embodiment 1

[0020] A high-build type impact-resistant and wear-resistant elastic coating with a deflecting structure, mainly comprising A component, B component and C component, and the weight and number ratio of the A component, B component and C component is It is: A:B:C=66:33:1, each component can be stirred under normal temperature and pressure.

[0021] The said component A mainly includes corundum, washed sand and wear-resistant vitrified microbeads. The components of component A are in the ratio of parts by weight: corundum: washed sand: wear-resistant vitrified microbeads = 2:5:3, and the components can be stirred at normal temperature and pressure. The emery is a silicon carbide material with various colors, which has high strength and good oxidation resistance. The washed sand is artificial washed sand with a fineness of 60 mesh to 80 mesh. The wear-resistant vitrified microspheres are hollow vitrified microspheres, which have the remarkable characteristics of high strength, l...

Embodiment 2

[0027] The difference between this embodiment and Example 1 is that the weight and number ratios of the A component, B component and C component are different, and the A component, B component and C component described in this embodiment The ratio of parts by weight is: A:B:C=50:40:1.2.

[0028] The ratio of parts by weight of each component of component A described in this embodiment is different from that in Example 1. The components of component A are in the ratio of parts by weight: corundum: washed sand: wear-resistant vitrified microbeads = 1:6:4.

[0029] The ratio of parts by weight of each component of component B described in this embodiment is different from that of Example 1. The components of the B component are in the ratio of parts by weight: one-component polyurea: toner: thixotropic powder = 90:5:3.

[0030] All the other are with embodiment 1.

Embodiment 3

[0032] The difference between this embodiment and Example 1 is: the difference between this embodiment and Example 1 is that: the weight and number ratios of the A component, the B component and the C component are different, and the A component, the B component and the C component are different. The weight ratio of component B and component C is: A:B:C=80:25:0.75.

[0033] The ratio of parts by weight of each component of component A described in this embodiment is different from that in Example 1. The components of the component A are in the ratio of parts by weight: corundum: washed sand: wear-resistant vitrified microbeads = 3:4:2.

[0034] The ratio of parts by weight of each component of component B described in this embodiment is different from that of Example 1. The ratio of the components of the B component is: one-component polyurea: toner: thixotropic powder = 100:1:1.

[0035] All the other are with embodiment 1.

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...
