Description

Method for manufacturing building materials and interior finishing materials using a gypsum}

The present invention relates to a method for manufacturing building materials and internal construction materials using gypsum, and more specifically, it is possible to manufacture internal construction materials using gypsum as a binder by condensation molding by mixing gypsum and natural products, and condensed gypsum. Unlike clay yellow or concrete, it has a dust on the surface and has a relatively high value in terms of strength. Therefore, the present invention relates to a method of manufacturing building materials and internal construction materials using gypsum, which can be used to make building materials applicable to tennis courts. .

In general, gypsum can be divided into natural gypsum and chemical gypsum, an industrial by-product. Natural gypsum currently depends on imports in Korea, but chemical gypsum is produced in Korea. Natural gypsum is mainly produced in the United States, Canada, France, Russia, etc. Gypsum is divided into dihydrate gypsum and half gypsum and anhydrous gypsum. Chemical gypsum is also obtained from phosphate gypsum, flue gas desulfurization gypsum, and titanium gypsum, except for hydrofluoric acid gypsum.

On the other hand, stone and soil have been mainly used as traditional building materials in our country. Soil has been used as a binder because it has excellent temperature control, emits far-infrared rays, and can be parasitic and viscous. However, the binding force was weak and easily lost when contacted with water, which was limited to use.

Stones were used in spheres and walls for heating purposes. It is known that when the stone is heated enough to emit far infrared rays, there are many therapeutic effects on the human body. However, as a lot of modern buildings are required and the life is complicated as in recent years, a large number of concrete buildings are being built, and a lot of adverse reactions occur. Especially due to the toxicity of concrete. It is known that concrete has a strong liquidity and releases ammonia and a small amount of aldehyde when the concrete is dried. Therefore, when entering a concrete structure, it may have a smoky smell, and even a newly built house or structure may cause headaches, dizziness or allergies for more than a year. Recently, in order to reduce such side effects, ocher paint may be painted on walls, and efforts are made to resolve the concrete poison as much as possible by using a non-concrete finish. As in Korea, if the four systems are distinct and the temperature difference is severe depending on the season, the floor is heated and heated. In the past, stone and soil were used as flooring materials, but since concrete is recently used, it can be said to be completely exposed to concrete docks.

In order to prevent direct exposure to the concrete dock, it is a good idea to apply concrete with ocher, etc. One such effort is gypsum board, but in the case of gypsum board, rock wool or other harmful substances are used to increase tensile strength. Sometimes there is a problem that is used only as a material for finishing the wall in addition to the construction.

The present invention has been invented to solve the problem of using only the gypsum board made of the wall product as described above, or the problem of not being able to directly install a floor, and the like, adding a natural product of ganban stone or germanium oxide to the gypsum or both. And kneading together with water to dissolve alumina alumina to provide a method of direct construction and use it as an internal construction material or by molding using a regular formwork to provide a building material.

For this purpose, the floor or wall was coated with gypsum, but natural porous cellulose, such as ganbanite and germanium oxide, was added to the gypsum and natural cellulose was mixed with 0.5mm ~ 2mm to increase the tensile strength. On the other hand, a fluidizing agent was used to increase workability during construction and to increase fluidity so that the gypsum structure of the coated surface has a dense structure. As the fluidizing agent, an aldehyde condensate of melamine sulfonic acid or an aldehyde condensate of naphthalene sulfonic acid was used. Magnetite, an oxide of iron, may be used to represent black, and a blue dye may be used to represent blue. The use of these dyes and oxides did not appear to have a significant effect on strength, unlike in concrete. A small amount of alumina sulfate is used to control the strength development time during construction. You can knead several of the mixtures previously obtained with water to build walls, floors, or tennis courts directly, but you can also apply kneaded mortar to your formwork or mold to build tiles or sidewalk blocks.
