Abstract

The invention discloses a waterproof coating for water conservancy construction. The waterproof coating for the water conservancy construction is characterized by comprising a first layer, a second layer and a third layer from inside to inside, wherein the first layer is made of a fiber-reinforced brittle composite material; manufacturing raw materials of the fiber-reinforced brittle composite material comprise Portland cement, silica sand, coal ash, water, water reducing agents, polyving akohol fibers and steel fibers; the second layer is made of epoxy-group and phenyl-group silicon resin; the third layer is made of the waterproof coating; manufacturing raw materials of the waterproof coating comprise bitumen, pozzolana cement, titanium nitride, calcium carbonate powder, water, dihydric alcohol reducing agents and epoxy emulsion; the thickness of the first layer is 2-3 millimeters; the thickness of the second layer is 1-1.2 millimeters; and the thickness of the third layer is 1.5-2 millimeters. The waterproof coating for the water conservancy construction is high in waterproof effect, can be adhered to concrete well, and is high in high-temperature resistance, high in impact resistance, high in crack resistance and high in friction resistance.

Description

technical field [0001] The invention relates to the waterproof field, in particular to a water conservancy building waterproof coating. Background technique [0002] Because reinforced concrete is cheap and easy to shape, it is used in the construction of many hydraulic structures such as dams, canals, locks and weirs. However, cracks in concrete due to thermal stress, autogenous stress, environmental exposure or mechanical loads can cause water penetration, adsorption, diffusion, and expose steel bars to water. In addition to being corroded by chloride ions or carbon dioxide, steel bars near water in concrete will also form chemical electron groups on the surface. These chemical electron groups will also cause corrosion of steel bars and will destroy building performance. Will destroy the integrity of reinforced concrete. Therefore, it is very necessary to apply a waterproof layer on the outer surface of the water conservancy infrastructure to isolate the facility from th...
