Abstract

The invention discloses an anticorrosive coating material for a concrete base material, wherein the anticorrosive coating material comprise a component A and a component B, the component A comprises,by weight, 0.1-0.5 part of modified graphene micro-powder, 36-54 parts of a fluorocarbon resin, 4-6 parts of an organic silicon resin, 1-2 parts of a drier, 1-3 parts of a mildew-proof and algae-proofagent, 1-3 parts of a leveling agent, 1-3 parts of a wetting dispersant, 1.5-3 parts of a coloring agent, and 1-3 parts of a defoaming agent, the component B comprises: 40-60 parts of a polyisocyanate prepolymer, a mass ratio of the component A to the component B is 1:2-4, and the modified graphene micro-powder is obtained by modifying graphene micro-powder with a silane coupling agent. Accordingto the present invention, by matching the modified graphene micro-powder, the fluorocarbon resin, the organic silicon resin and the polyisocyanate prepolymer according to a certain ratio, the anticorrosive performance of the coating is effectively improved, and the anticorrosive coating material has excellent comprehensive performance. The invention further provides a construction method of the anticorrosive coating material.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-corrosion coating for concrete substrates and a construction method thereof. Background technique [0002] Concrete structure is one of the most widely used traditional materials at present. It is widely used in various fields such as basic buildings, roads and bridges, water conservancy and hydropower, and marine engineering. By the end of the last century, the annual concrete consumption in the world was about 70 million tons, while the annual concrete consumption in my country was about 7 million tons. With the further in-depth development of my country's economy, my country's concrete structure facilities will increase year by year, and the amount of concrete will only increase. Concrete structures play a pivotal role in various infrastructures in our country. However, concrete structure is a kind of porous medium material. During the application proces...
