Problems solved by technology

Solvent-based waterproof coatings contain organic solvents, long-term use is poisonous and harmful to the human body and the environment, and their safety is poor. Oily waterproof coatings will be fattened and cracked when they are in contact with water for a long time.
Although water-based waterproof coatings do not contain organic solvents, water-based waterproof coatings usually have poor adhesion and unstable waterproof effects

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-efficiency, environment-friendly, anti-corrosion and waterproof coating for subway shield segments and a preparation method thereof. Background technique [0002] The waterproof coating used in the construction industry is generally a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it will form a waterproof film on the surface of the base layer after solvent volatilization or water evaporation or reaction curing. At present, the waterproof materials used in the construction industry are generally divided into flexible waterproof materials including waterproof membranes, waterproof coatings, sealing ointments, etc., and rigid waterproof materials based on cement substrates, adding waterproofing agents and other additives. Although there are many types, they generally have disadvantages such as poor physical and mechanical p...
