Background
At present, the mainstream waterproof and impervious materials in China form five categories of asphalt and modified asphalt waterproof coiled materials, synthetic polymer waterproof coiled materials, waterproof coatings, sealing materials and rigid water-stopping and plugging materials. Various waterproof materials play a great role in waterproofing, permeability resistance, sealing and leakage stoppage of various buildings. However, in current practice, there is no very suitable and effective material and method for rapidly treating the seepage of some back water surfaces and the water-carrying interfaces such as elevator shafts, matrixes and the like. There are generally two types of materials commonly used today in such applications:
(1) a permeable crystallization type waterproof coating. The permeable crystallization type waterproof coating has the advantages of permeable crystallization, corrosion resistance, concrete compactness increasing and concrete strength improving, but the construction strength is slowly developed under the condition of open water and even leakage, the maintenance period is long, and the requirement of rapid water resistance and impermeability cannot be met.
(2) The water is not leaked. The quick-setting type water leakage-free setting time is fast, and the setting is not as early as the setting in batch scraping construction; although the initial setting time of the delayed coagulation type water-tight is more than 10 minutes, the delayed coagulation type water-tight is still very hasty for large-area batch plastering construction, the delayed coagulation type seepage-resistant pressure is lower and is only 0.4MPa, and the delayed coagulation type water-tight and polymer emulsion are frequently compounded into slurry on site for use so as to achieve the effects of quick water stopping, water proofing and seepage resistance. However, the operation is carried out from raw materials, site proportioning, process and the like completely according to experience of site operators, and no specification is provided; the standard and regulation are followed, and the waterproof effect is difficult to guarantee at all.
The existing quick-setting waterproof slurry has high strength of a formed waterproof layer when the hardening speed is high, but the construction time is short, a constructor usually has no time to adjust the adhesion thickness and the surface smoothness of the waterproof slurry at a target waterproof position, the waterproof slurry is already solidified, so that the formed waterproof layer is not uniform, the integral waterproof property is influenced, particularly the waterproof difficulty in recent years is high, the waterproof property of a top layer of a building is large, the requirement on the waterproof property is high, the existing quick-setting waterproof slurry is used, the setting speed is too high, the waterproof effect of the formed waterproof layer is poor, the integral construction period is long when the setting speed is reduced, the construction efficiency is influenced, and the formed waterproof layer has low strength and is easy to damage.
