As a further technical scheme, the mass ratio of the accelerator to the retarder is 2: 1.
The invention also provides a using method of the high-efficiency inorganic rigid waterproof coating, which is characterized in that the raw material of the waterproof coating and water are mixed and coated on the surface of a base material to form the waterproof coating with the thickness of 1.5-2 mm.
The invention has the beneficial effects that:
1. the invention provides a brand-new skin type waterproof coating, which takes cement as a carrier and other components for assisting and cooperating, wherein the content of inorganic materials such as cement, zeolite and the like is larger, so that the waterproof coating is essentially an inorganic material and is different from the existing high-molecular waterproof material. The inorganic rigid waterproof material of the invention has the service life theoretically equivalent to that of structural concrete, and the aging resistance is far higher than that of a high-molecular waterproof material. The waterproof coating of the invention thoroughly solves the phenomenon of 'two sheets' and 'interlayer water leakage' between the waterproof layer and the base layer, and the waterproof system has high stability and high fault tolerance; the service life of the waterproof layer is the same as that of the building, and the social and economic benefits are remarkable; the construction can be carried out on a wet base surface, and the water can be prevented from being leaked on a water back surface; in the existing waterproof system, waterproof mortar close to the system of the invention needs to be coated by 10-20 mm in blade coating during construction, but the waterproof coating of the invention can realize better waterproof effect when being constructed to be 1.5-2 mm thick, and thick coating is not needed.
2. After the structural concrete is formed and demoulded, the waterproof coating rebuilds a rigid waterproof layer on the surface of the structure, is independent of the quality of the base concrete, and can be used for damp base construction. The waterproof mortar is suitable for concrete waterproofing and masonry waterproofing (aerated blocks and brick masonry); the waterproof coating can be applied to large-area and large-volume waterproof projects such as underground projects, roofing projects and the like, and can also be applied to sporadic working surfaces such as toilets, kitchens and the like; the method can be applied to new construction and also can be applied to the water leakage maintenance engineering of the back water surface.
3. The anti-permeability agent, the reinforcing agent, the water reducing agent and the defoaming agent in the invention act together to reduce bubbles in the coating, enhance the compactness and strength of the coating and increase the impermeability of the coating. The dispersible latex powder is matched with cellulose ether for use, so that the workability during construction is improved, the water retention and the impermeability of the coating are enhanced, but the addition amount of the cellulose ether is not too much. The white carbon black is used as high-activity nanoscale mineral micro powder, has a microcosmic compaction effect, improves and stabilizes the internal structure of the coating, enhances the impermeability effect, can improve the free flowability of the product, and has the effect of continuously enhancing the later strength of the coating. The cellulose ether can play the effect of moisturizing thickening on the one hand, and on the other hand, because the existence of the polymer long chain material in the cellulose ether structure, still further played the effect that improves adhesive strength, improved waterproof coating's mechanical properties.
4. The zeolite powder is added in the invention, so that other materials can be adsorbed, and the workability is improved. The active components in the zeolite powder can react with the hydration product calcium hydroxide of the cement to generate gelled substances, thereby improving the strength. The zeolite powder with different grain diameters is calcined at different temperatures, after the two kinds of zeolite with different calcination temperatures and fineness are compounded according to a certain proportion, anhydrous sodium sulphate is added, and an anti-permeability modifier obtained by polyvinyl alcohol and sodium dodecyl sulfate is used as an auxiliary material, so that the anti-permeability performance and the strength of the waterproof coating can be improved. However, if the calcination temperature of the high-temperature calcined zeolite is too high, the structure of the zeolite is changed, the loading effect is poor, and the effect of the anti-permeability modifier for enhancing the anti-permeability is poor. According to the invention, the high-temperature calcined zeolite and the low-temperature calcined zeolite are compounded according to a specific proportion, particles with different fineness are fully contacted, under the action of polyvinyl alcohol and sodium dodecyl sulfate, the high-temperature calcined zeolite and the low-temperature calcined zeolite form a uniform and compact system, and after the high-temperature calcined zeolite and the low-temperature calcined zeolite are used, capillary gaps can be filled, so that the anti-permeability performance and the strength of the waterproof coating are improved to the maximum extent.

Table 8 performance of the waterproof coating of comparative example 2
Various performances of the inorganic rigid waterproof coating obtained in the embodiment of the invention far exceed national standards, wherein various performances of the embodiment 4 are the best. In example 5, only the high-temperature calcined zeolite was added, the strength of the waterproof coating was reduced as compared with example 4, and the anti-permeation performance was not as good as that of example 4. In the invention, only two calcined zeolites are compounded to play the best role of improving the impermeability and strength. In example 6, the content of the low-temperature calcined zeolite is increased as compared with that in example 4, the obtained waterproof coating has reduced permeation pressure resistance, compressive strength and flexural strength, and the low-temperature calcined zeolite and the high-temperature calcined zeolite in the invention can achieve the best permeation resistance enhancing effect according to a specific ratio. In comparative example 1, polyvinyl alcohol was not added, which resulted in poor adhesion of the material obtained by compounding two kinds of zeolites in the anti-permeability modifier, poor filling effect of the material in the capillary gap, and reduction of various properties. The addition of more cellulose ether in comparative example 2 may result in poor workability and poor dispersibility of the system, thereby affecting the mechanical properties of the coating.
Other test results of the waterproof coating in example 1 of the present invention are shown in table 9, and the performance of other examples is similar to example 1 and thus omitted.
