Exterior wall waterproof material
The invention discloses an exterior wall waterproof material, comprising liquid material and powder material. The weight ratio of the liquid material to the powder material is 1:(2-4); the liquid material is vinyl acetate-ethylene copolymer emulsion; the powder material is made with Portland cement, quartz sand, plasticizer and penetrant according to the weight ratio: (15-18):(20-24):1:1. The exterior wall waterproof material is both rigid and flexible and has the advantages of both the rigid material and the flexible material; added with various unique material compositions and active factors, the exterior wall waterproof material is excellent in waterproofing and impervious performances, is resistant to high and low temperatures, ageing resistant, high in weatherability, nontoxic and odorless and green, allows double waterproofing by single construction, is resistant to long-term soaking, and has certain anticorrosion effect; during construction, the exterior wall waterproof material is rarely destructed, water leakage rarely occurs even if a waterproof layer is destructed, water channeling or water leakage never occurs even if a base layer is severely damaged, a leak point is easy to locate, and local repairing is required only.
