Cement-based penetrable crystallized waterproof paint, preparation method and construction method thereof

Abstract

The invention relates to a cement-based penetrable crystallized waterproof paint, a preparation method and a construction method thereof. The cement-based penetrable crystallized waterproof paint is prepared from the following raw materials in percentage by weight: 65 to 70 percent of cement, 3 to 10 percent of modified bentonite, 2 to 5 percent of modified sodium silicate, 1 to 5 percent of diffusant, 0.5 to 1 percent of penetrant, 2 to 10 percent of wollastonite and 15 to 25 percent of quartz sand. The waterproof paint can recover minute cracks on concrete interfaces and inhibit the water seepage and damp of base interfaces effectively. In addition, the waterproof paint is high in capacity of freezing resistance, high-temperature resistance, chloridion resistance and acid and alkali resistance, and has a long waterproof effect. According to the cement-based penetrable crystallized waterproof paint, leveling layers on the concrete interfaces are saved, and protective layers are savedafter the concrete interfaces are coated, so the waterproof construction is simple. The cement-based penetrable crystallized waterproof paint is suitable for constructional engineering such as underground engineering, subway tunnels, civil air-defense construction, water ponds, oil sumps, sewage tanks, barns, bathrooms, roof squares, parking platforms, high-grade roadways and the like, and is used for processing defects of cracks, honeycomb pitted surfaces and the like of the concrete interfaces.

Description

technical field [0001] The invention relates to a building waterproof paint, a preparation method and a construction method thereof. Background technique [0002] In industrial and civil reinforced concrete construction projects, due to the poor impermeability and waterproof performance of concrete materials, cracks are prone to occur on the surface of buildings and water leakage occurs. The method of laying waterproof membranes or painting paint on the concrete surface not only has high cost and complicated construction methods, but also has problems such as poor durability and environmental pollution. [0003] In recent years, cement-based permeable crystalline waterproof coatings have been widely used in construction projects such as subways, tunnels, and reservoirs. and other materials (such as the Chinese invention patent application with the publication number CN1472160A, and the Chinese invention patent application with the publication number CN101759414A). The bent...
