MULTIFUNCTIONAL BENTONITE WATERPROOFING MATERIAL OF BENTOTEX, BENTOSHEET, BENTOSOIL, AND BENTOSPRAY USING BENTONITE AS MAIN MATERIAL

摘要

The present invention relates to a multifunctional bentonite waterproofing material. In order to have various functions, such as a fresh water expansion function, a salt water expansion function, a pollution purification function, an uneven part application function, a reinforcement function, and others, the waterproofing material is formed by selectively laminating one or more among bentotex, bentosheet, bentosoil, and bentospray comprising one or more functional materials among bentonite having an expansion function, CM powder having a binding gel function, PM powder having an expansion function and a hydrogel function, zeolite having a pollution purification function, fiber having a reinforcement function, and a mixture thereof. In the bentotex, the functional material is embedded between two or more among a woven fabric, a non-woven fabric, and a film and is bonded by needle punching, sewing, and bonding with an adhesive. The bentosheet is formed by spraying or laying the functional material, the slurry of the functional material, or a mixture in which the functional material is mixed with starch, spraying or laying them with water, or spraying or laying them with an adhesive on the surface of one among a sheet and a film or one or both sides of a bonded surface. The bentosoil is formed by mixing, laying, and solidifying the functional material with/to soil, with/to one or more among soil, waste powder, waste soil and stone, and constructional earth and sand, or with/to soil and fiber. The bentospray is formed by spraying or laying the functional material, the slurry of the functional material, or the mixture in which the functional material is mixed with the starch, spraying or laying them with water, or spraying or laying them with an adhesive.;COPYRIGHT KIPO 2015
