Problems solved by technology

However, the concrete structure is directly exposed to the air, and is affected by factors such as carbonization and vulcanization, fluoride penetration, salt crystallization, freeze-thaw action, external force, rain erosion or changes in cold and heat, which greatly reduces the safety of the concrete structure. and service life
The traditional coating protection method is to use water-based putty to level the concrete surface, and then paint the leveling layer for protection. Hazards such as putty peeling off, paint coating easy to foam, crack, fall off, and discoloration often occur, thus affecting the overall image of concrete buildings

Abstract

The invention discloses an isolating type coating and method for concrete repair and protection. Epoxy putty is adopted, has good cohesive action with a concrete base material, and can be completely integrated with the concrete base material, so that a corrosive medium can be completely isolated, and the state where the coating does not foam and drop is guaranteed; the sealing effect is excellent,and the corrosion resistance is good, so that construction can be performed in a humid environment and a drying environment; surface coating water-based double-component fluorocarbon coating is usedfor bridge surface decoration and durability protection, and the formed coating has excellent adhesion, weather resistance, acid and alkaline resistance, and a self-cleaning effect, so that the concrete structure is free of maintenance for a long time. The isolating type coating and method for concrete repair and protection can repair a concrete base surface, and also can continuously isolate erosion, on concrete, of a corrosion factor, so that new and old concrete repair and protection problem is effectively solved, the safety, durability and decoration of the concrete structure are improved;and the coating is simple in system, convenient to construct, and environmentally friendly.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an isolation coating and method for concrete repair and protection. Background technique [0002] Concrete structures play an important central role in modern architecture. Due to the rapid economic development, various types of concrete buildings have developed very rapidly. With the continuous improvement of the public's requirements for urban landscape, the safety and beauty of concrete buildings are becoming more and more important. However, the concrete structure is directly exposed to the air, and is affected by factors such as carbonization and vulcanization, fluoride penetration, salt crystallization, freeze-thaw action, external force, rain erosion or changes in cold and heat, which greatly reduces the safety of the concrete structure. and useful life. The traditional coating protection method is to use water-based putty to level the concrete surface, and then paint ...
