Description
Technical Field
The invention relates to the technical field of building coatings, in particular to a flexible waterproof coating and a coating method thereof.
Background
The waterproof coating is a single-component water-emulsion waterproof coating prepared by taking polymer emulsion as a base material and adding other additives. The waterproof film formed by curing the waterproof coating has certain extensibility, elastoplasticity, crack resistance, impermeability and weather resistance, and can play roles in waterproofing, seepage prevention and protection. There are two main types of waterproof coatings on the market: one is waterproof polyurethane paint. Such materials are generally made from polyurethane and coal tar as raw materials. The volatile tar gas has high toxicity and is not easy to remove, so the volatile tar gas is prohibited to be used in China in 2000. The polyurethane waterproof paint is sold by replacing coal tar with asphalt as raw material. However, when such a coating material is used, it is generally diluted with an organic solvent containing toluene, xylene, etc., and thus it also has toxicity; another class is polymer cement based waterproofing coatings. It is composed of emulsion synthesized by several water-base polymers and high-quality cement mixed with various additives, and the flexibility of polymer (resin) and rigidity of cement are combined into one body, so that it is excellent in impermeability and stability. Its advantages are convenient construction, low cost, short construction period, no poison and environmental protection. Thus, polymer cement-based has become a leading element of the waterproof coating market.
Although the existing waterproof coating is simple to construct, the weather resistance is poor, and the existing waterproof coating is easy to crack under the vibration condition and even breaks away from a base layer to lose the waterproof effect. The existing waterproof coating has the problem of poor heat resistance in the use process, and has high fluidity at high temperature; and the low-temperature flexibility is poor, so that the use of the waterproof coating is limited, and the use environment and the construction environment are limited.
