Description

{ENVIRONMENT FRIENDLY MATERIAL FOR BUILDING}

The present invention relates to a functional eco-friendly construction material, and more particularly, it relates to a functional eco-friendly construction material, which is composed of only 100% natural materials, and can not detect and emit volatile organic compounds, formaldehyde, heavy metals, It is a construction material that can be treated. It can remove moisture to prevent condensation inside the building, but it is made of flame retardant. It does not emit toxic gas in case of fire, provides antibacterial and deodorizing effect, aromatherapy effect, The present invention also relates to a functional eco-friendly construction material in which the efficiency of the worker is improved and the competitiveness of the product is enhanced because the production time required for the drying process is short.

Generally, refractory bricks and floor panels, tiles, etc., which are generally used in the field of construction, are produced by molding clay in a mold and then plasticized to a desired shape at a high temperature. It has been required to provide various functions not only in architectural materials but also as architectural finishing materials or building materials. In addition, existing building materials have made many improvements in terms of practicality and design, but they are not environmentally friendly. Therefore, there is a problem in that the generation of formaldehyde, the detection of toxicity such as volatile organic compounds, and the detection of heavy metals during the production and use of building materials cause various skin diseases, bronchial diseases, headache and the like. In consideration of this aspect, in the registered patent No. 352139, tiles are produced by mixing yellow earth, charcoal, and jade with PVC, but this is also used as a chemical material of PVC, so that the environment- . In addition, JP-A-2002-41352 discloses a method of producing charcoal by mixing purified charcoal with epoxy by purifying char, but there is a problem that epoxy cools the pores of charcoal by mixing epoxy and charcoal, There is a limit that is not environmentally friendly because it is not a substance. In addition, although a functional building material is disclosed in Patent Document 10-0677761, since the manufacturing process is complicated by using an aqueous gelatin solution, the drying time of the product is at least 24 hours to 3 days, % There is a remarkable technical difference from this company which can produce eco-friendly products. These conventional technologies are economical and environmentally friendly in that 100% of all materials are natural materials, and the production process is dramatically shortened due to a rapid drying time and production using natural wastes. Also, it is excellent in moisture removal and excellent in flame retardancy And can not follow the present invention which suggests a construction material having excellent strength and durability.

1 is a view of a functional eco-friendly building material according to an embodiment of the present invention.
2 is a view of a functional eco-friendly building material according to another embodiment of the present invention.
FIG. 3 is a photograph illustrating a state in which the construction material is constructed using the present invention.

1 to 3, the functional eco-friendly construction material of the present invention is classified into gypsum, shell powder, chaff charcoal, charcoal, water, and natural materials. Hereinafter, the components will be described in detail as follows.

The composition of the mixture according to the present invention is composed of gypsum: shell powder: chaff charcoal and charcoal: water: natural material in a weight ratio of 14: 8: 2.5: 10: 1, To provide strength strength and to provide strength strength, water resistance and durability suitable for building materials due to the mixing action of gypsum at a ratio of 14 and shell powder at a ratio of 8. The shell powder produces an annual average of 250,000 tons of oysters. Since only about 10% of the shells of about 150,000 tons are used per year, in order to solve the difficulty of shell processing from the oyster farm and to solve the environmental problems that lead to unauthorized use, To provide technology to produce building materials. The shell powder is a strongly alkaline substance containing 98% or more of calcium carbonate, and the shell powder having a ratio of 8 is reacted with gypsum having a ratio of 14 and water having a ratio of 10 to enable sufficient strength development as a building material . If the gypsum ratio exceeds 14, the strength enhancement effect as a building material is not exhibited. If the gypsum ratio is less than 14, the reaction with the shell is not easy. When the proportion of the shell powder exceeds 8, the strength improving effect as a building material is not exhibited. When the shell powder ratio is less than 8, the bonding amount with the gypsum is decreased and the strength as a building material is not exhibited. If the ratio of water is more than 10, it is difficult to exert the superfluous strength force. If the ratio of water is less than 10, the reaction with other materials is not easy, and the strength as a building material is also not exhibited. Therefore, the blending ratio of the constituent materials according to the present invention is critical. Chaff charcoal is a charcoal that is loaded with charcoal for the dehumidification function. Charcoal that is added with chaff charcoal emits far infrared rays and anion and regulates moisture. Since charcoal has many pores, Moisture is absorbed in the case of high humidity, and moisture is released in case of drying to prevent corruption and deodorization. These chaff charcoal and charcoal are administered at a ratio of 2.5, so that the dehumidifying power is exerted without weakening the strength. As a natural material, green tea extract, mugwort extract and eucalyptus oil are used as a mixture of one or three kinds. The catechin of green tea acts as an antimicrobial agent and deodorant and provides an aromatherapy effect through the green tea aroma . Mugwort has a unique fragrance. In the scent of mugwort, Chineol has the effect of killing E. coli and Diphtheria bacteria and inhibiting growth, so it is used in construction materials to induce the prevention of fungal growth due to condensation. Eucalyptus oil has a strong bactericidal action, so it is injected to provide fungi and its insecticidal effect through building materials and to give aromatherapy effect. Such natural materials are added at a ratio of 1 in total.

The constituent material mixed at such a ratio is formed by compression molding and drying at room temperature for 1 to 2 hours. That is, the conventional building materials made of natural materials took at least 24 hours to 3 days to dry. However, when manufactured with the constituent materials and contents according to the present invention, it is possible to produce building materials having strength in 1 to 2 hours from drying, It is possible to provide an efficient and efficient construction material.

The building material of the present invention can be made of a block, a board, a tile or a plate material. That is, as shown in FIG. 1, it can be manufactured in the shape of a cylinder and can be manufactured to fit the space where the installation is required. As shown in FIG. 2, It is also possible to install it invisibly.

The functional eco-friendly construction material according to the present invention was cut at intervals of 25 cm width, 8 cm length and 1 cm thickness, and then a plurality of specimens were prepared, and the amount of antifungal and formaldehyde dispersion was measured.

Penicillium pinophilum ATCC 11797 and Gliosiadium virens ATCC 9645 were used as antifungal test strains. Test Items Duration of incubation One week after 2 weeks Three weeks Four weeks Test Methods ASTM G-21 Test result 0 0 0 0

As a result of the antifungal test, the mycelium was not expressed even after the elapse of 4 weeks.

 Measurement of formaldehyde dispersion Test Items Test Methods result Formaldehyde dissipation (mg / L) KS F 3200-'02 Not detected

As can be seen from the table, it can be seen that the product according to the present invention does not emit formaldehyde and is environmentally friendly.

The present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
