Film-forming permeable waterproof material, preparation method and application thereof

Abstract

The invention discloses a film-forming permeable waterproof material, and a preparation method and application thereof. The waterproof material comprises a component A and a component B. The componentA comprises sodium silicate, a surfactant, a reaction retarder, a reducing agent, a reaction promoter, an anti-freezing agent, a metal ion blocking agent, a surface enhancer, an antirust agent, a photoinitiator, a cross-linking agent, water and an acrylate emulsion. The component B comprises white cement, gypsum, silica fume, mineral powder, fly ash, citric acid, magnesium fluosilicate, magnesiumoxide, sodium silicate, a reinforcing component and fumed silica. The film-forming permeable waterproof material is suitable for various environments, can achieve a good waterproof effect on buildingstructures in any environment, and can form a seamless complete high-strength waterproof coating film to prevent leakage; large-scale machining is not needed, the production efficiency is high, the investment is small, the construction is convenient, heating and boiling are not needed, environmental protection and no pollution are realized, and the labor cost is greatly reduced.

Description

technical field [0001] The invention relates to a waterproof material for construction, in particular to a waterproof material capable of forming a film and penetrating, as well as its preparation method and application. Background technique [0002] Compared with traditional waterproof materials, water-based permeable inorganic waterproofing agent has irreplaceable advantages. Compared with surface film-forming waterproof materials, it has the advantage of crystallization by chemical reaction to form crystals to block the cracks and pores inside the concrete; and Compared with organic waterproof coatings, there is no irritating odor and aging problems, and it has the advantages of good weather resistance, non-toxic and green environmental protection; the depth of crystals is generally deeper than that of surface film-forming waterproof materials, and it has crystallization, automatic repair functions, Breathability and other advantages. Water-based permeable inorganic wate...

Problems solved by technology

[0006] Purpose of the invention: Aiming at the problems existing in the prior art, the present invention provides a waterproof material that is both film-forming and permeable. Achieve good waterproof effect, especially suitable for projects in various extreme environments and some complex scenes in the building repair market, as well as waterproof projects in some special areas and projects, especially underground projects, and regardless of various planes, slopes, and facades, Complicated and irregular parts such as irregular surfaces can form a seamless high-strength waterproof coating film to prevent leakage; and without large-scale mechanical processing, high production efficiency, low investment, convenient construction, and no heating and boiling , green, environmentally friendly and pollution-free, and greatly reduce labor costs, avoid problems such as long maintenance time for permeable materials, and it is difficult to distinguish the actual effect from the appearance after use, and the waterproof effect is unstable, and it can also avoid the problem of film-forming materials. Problems such as low impermeability
