Abstract

The invention discloses a downstream face waterproof material with soft exterior and rigid interior as well as a preparation method and an application of the downstream face waterproof material. The waterproof material comprises a component A and a component B. The component A comprises emulsified asphalt, an acrylate emulsion, an alkali swelling thickener, a polyurethane thickener, a dispersant,a multifunctional auxiliary agent, an antifoaming agent, a bactericide, ground calcium carbonate powder, bentonite, an organosilicon water repellent, sodium silicate, a photoinitiator, a cross-linkingagent and water; and the component B comprises sulphoaluminate cement, gypsum, silica fume, mineral powder, fly ash, citric acid, magnesium fluosilicate, magnesium oxide, sodium silicate, a reinforcing component and fumed silica. The waterproof material disclosed by the invention has rapid curing and self-healing properties; the material has the advantages of strong water impermeability, high tensile strength, high bonding strength and high and low temperature resistance, solves the problems that secondary or tertiary coating and vertical surface sagging cannot be carried out on a base surface of a downstream surface in a short time, and the vertical surface coated with the coating cannot be tiled and a pipe root part cannot be used, and has a wide application range.

Description

technical field [0001] The invention relates to a waterproof material for building, in particular to a backwater surface waterproof material with a soft exterior and a rigid interior, as well as a preparation method and application thereof. Background technique [0002] In recent years, due to reasons such as design, construction, structure, and material selection, leakage of building exterior walls has occurred frequently, especially in the east and west gables and exterior walls with strip exterior wall bricks, mosaics and other materials as finishes. The large area and its seriousness are no less than that of the roof, which directly affects the normal use of the building, and has aroused great concern from the construction authorities and relevant parties. With the improvement of people's requirements for housing quality, the call for controlling the leakage of external walls is very high and urgent. However, due to factors such as housing property rights, property mana...
