Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by a person skilled in the art that the embodiments and features of the embodiments in the present application can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic structural view of an embodiment of the waterproof structure of a building of the present invention. As shown in fig. 1, the waterproof structure for buildings according to the present embodiment includes a base layer 1, and an inorganic composite waterproof layer 2 coated on the base layer 1, wherein the inorganic composite waterproof layer 2 includes a cement-based permeable crystalline waterproof layer 21 and a bentonite waterproof layer 22.
The base layer 1 is typically a reinforced concrete panel. The cement-based capillary crystalline waterproof layer 21 and the bentonite waterproof layer 22 are stacked. In this embodiment, the cement-based capillary crystalline waterproof layer 21 and the bentonite waterproof layer 22 are sequentially stacked on the surface of the base layer 1 from inside to outside, with the surface of the base layer 1 as a boundary; namely, the cement-based capillary crystalline waterproof layer 21 is coated on the surface of the base layer 1, and the bentonite waterproof layer 22 is coated on the surface of the cement-based capillary crystalline waterproof layer 21 on the side away from the base layer 1. In other embodiments, the bentonite waterproof layer 22 may be disposed on the surface of the base layer 1, and the cement-based capillary crystalline waterproof layer 21 may be disposed on the surface of the bentonite waterproof layer 22 facing away from the base layer 1. The thickness of the cement-based capillary crystalline waterproof layer 21 is generally 0.8 to 1.5mm, and the cement-based capillary crystalline waterproof layer is formed by coating a cement-based capillary crystalline waterproof material (CCCW). The cement-base permeable crystallization type waterproof paint is a powdery rigid waterproof material which is prepared by using special cement, quartz sand and the like as base materials and doping various active chemical substances, belongs to a commercial product and can be directly purchased from the market.
In this embodiment, the bentonite waterproof coating layer 22 includes a calcium-based bentonite waterproof layer 221 and a sodium-based bentonite waterproof layer 222. The sodium bentonite has good swelling performance, can swell 10-30 times in contact volume with water, and forms a gel film through hydration swelling, so that a waterproof effect is achieved; however, the water absorption rate is slow, and the hydration is usually started after the water is contacted with the water for about 24 hours, and the hydration is completed after about 48 hours. The swelling performance of the calcium bentonite is relatively poor, the volume of the calcium bentonite is expanded by about 3 times after the calcium bentonite fully absorbs water, but the water absorption speed of the calcium bentonite is increased to a great extent, and the calcium bentonite is rapidly slowed down in the later period. Therefore, the calcium bentonite and the sodium bentonite are matched with each other to prepare the composite bentonite waterproof layer by utilizing the characteristics that the calcium bentonite has a waterproof effect in the early stage and the sodium bentonite has a low water absorption speed and a good waterproof effect, so that the waterproof effect can be effectively improved. The thickness of the sodium bentonite waterproof layer 222 is generally 1-2 mm, and the thickness of the calcium bentonite waterproof layer 221 is generally 0.5-1 mm.
Because the water absorption speed of the sodium bentonite is low, the water absorption speed of the calcium bentonite is high in the early stage and low in the later stage, the calcium bentonite waterproof layer 221 is preferably arranged on the outermost layer, namely the cement-based capillary crystalline waterproof layer 21 and the sodium bentonite waterproof layer 222 are arranged between the base layer 1 and the calcium bentonite waterproof layer 221 in a stacking manner, so that the calcium bentonite waterproof layer 221 on the outermost layer is preferentially protected. In this embodiment, the surface of the base layer 1 is used as a boundary, the cement-based capillary crystalline waterproof layer 21, the sodium-based bentonite waterproof layer 222 and the calcium-based bentonite waterproof layer 221 are sequentially stacked on the surface of the base layer 1 from inside to outside, that is, the cement-based capillary crystalline waterproof layer 21 covers the surface of the base layer 1, the sodium-based bentonite waterproof layer 222 covers the surface of the cement-based capillary crystalline waterproof layer 21 on the side away from the base layer 1, and the calcium-based bentonite waterproof layer 221 covers the surface of the sodium-based bentonite waterproof layer 222 on the side away from the cement-based capillary crystalline waterproof layer 21. Of course, in other embodiments, the sodium-based bentonite waterproof layer 222, the cement-based capillary crystalline waterproof layer 21, and the calcium-based bentonite waterproof layer 221 may be sequentially stacked on the surface of the base layer 1.
In addition, in order to improve the reliable stability of the above waterproof structure of the building, an interfacial agent layer may be disposed between the layers or between the layers in the middle of the layers, so as to achieve the stable adhesion between the layers through the interfacial agent layer. For example, an interfacial agent layer may be provided between the inorganic composite waterproof layer 2 and the base layer 1; an interfacial agent layer can also be arranged between the cement-based capillary crystalline waterproof layer 21 and the bentonite waterproof layer 22; an interfacial agent layer and the like may be further provided between the sodium-based bentonite waterproof layer 222 and the calcium-based bentonite waterproof layer 221. The interface agent has the characteristic of bidirectional permeation and adhesion, can generate a radioactive chain type anchoring effect to permanently and firmly bond bidirectional materials together, has high flexibility, toughness, freeze-thaw resistance, water resistance, aging resistance, acid and alkali resistance and weather resistance, is nontoxic and tasteless, is applied to bonding of middle layer bodies of a waterproof structure of a building, and can improve the stability of the whole structure while ensuring the waterproof performance and the durability of the waterproof structure. The material of the interface agent layer is preferably emulsion type interface agent which is used as a bonding agent, belongs to commercial products and can be directly purchased in the market. The thickness of the interfacial agent layer is generally 0.2 to 1 mm.
In the building waterproof structure of the utility model, the cement-based capillary crystalline waterproof coating has the effect of promoting the cement-based material to carry out self-repairing, can lead the microcracks in the waterproof mortar to automatically heal, can fully absorb the water on the surface of the base layer to participate in the crystallization reaction, can not cause the hollowing phenomenon, has good sealing and waterproof effects, strong durability and strong pressure resistance; the bentonite is a natural inorganic nano waterproof material, is not easy to age, has strong durability and unique expansion capability, and can automatically repair cracks within 2 mm; the bentonite waterproof layer and the cement-based capillary crystalline waterproof layer are compounded to form the inorganic composite waterproof layer, the bentonite waterproof layer and the cement-based capillary crystalline waterproof layer can be matched with each other to repair cracks and strengthen waterproofing, excellent crack repairing effect can be obtained, the formed waterproof structure is strong in durability, and the permanent waterproof effect can be achieved.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
