Description

A composition of multi-functional cement terrazzo using ceramic materials and preparation method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the manufacture of slip casting type or hydraulic press type cement terrazzo, which is made of natural ceramic material, which is used in the floor of a building for wear resistance, high strength, and no cracking due to shrinkage. The present invention relates to a method for producing a functional cement terrazzo having excellent anion and far-infrared radiation, excellent antibacterial and anti-fungal performance by using a specific ratio of a ceramic material of a special component to cement terrazzo.

Terrazzo has been used for floor finishing for a long time. Because of its robustness, beauty, and ease of management, it is no exaggeration to say that it has been almost standardly installed in commercial and large-scale buildings. Like other building materials, these terrazzos have developed their technology, and the improvement of materials has also been clearly changed. The terrazzo has also been developed extensively in the method of mixing raw materials and construction, and the technology is sufficient to satisfy both beauty and use. In today's development, the scope of its use is also greatly expanded.

In recent years, in order to improve the living environment of human beings exposed to various harmful substances, our country has enacted indoor air purification methods and demanded more eco-friendly living. This is an indispensable measure for health as an effort to improve the current living environment that is easily exposed by various chemicals used in buildings. The destruction of the living environment in residential spaces, such as buildings, is caused by various chemicals used in various processes of the building. The main culprit behind the destruction of the living environment is the adhesive of wallpaper and formaldehyde and volatile organic compounds contained in wood. have. Many bio-functional materials have been developed at the time of this request. However, this attempt is simply applied to the walls of concrete structures, and the effectiveness of the coatings on the order of several micrometers is questioned. Moreover, since the wallpaper is wallpapered by the adhesive again on the coated surface, sufficient effect is hardly exerted. In addition, the materials used are mainly jade ore powder or elvan powder, they can exhibit the far-infrared emissivity function, but the deodorization effect by adsorption is difficult to expect.

The present inventors have found that the scoria minerals excavated in parts of Korea are excellent in far-infrared emissivity and anion emission, and applied them to the functional cement terrazzo. In addition, the scorier contained fine independent pores inside, which had excellent deodorizing effect by adsorption, and contained about 3% or more of titanium dioxide, which is the main raw material of the photocatalyst, by weight ratio, resulting in odor resolution.

Skorier is a mineral distributed in parasitic volcanic areas. Porous volcanic rocks, volcanic ash, and volcanic sand are contained among the various substances emitted when the volcano erupts. It is becoming. In addition, due to the various components contained in the volcanic eruption, it has a characteristic of high radiation rate such as far infrared anion.

The inventors of the present invention have tried to utilize the mineral and chemical adsorption characteristics of the scorer to utilize the cement terrazzo for building floors. In addition, the weight of the building is reduced as much as the use of a scorer, thereby reducing the load of the building, and thus completing the invention of the multifunctional cement terrazzo, which can extend the life of the building.

Functional cement terrazzo manufacturing method using volcanic eruptions as in the present invention is not known in the prior art.

An object of the present invention is to prepare a functional cement terrazzo including a scourier, which is a mineral by volcanic eruptions, in a cement terrazzo composition comprising cement as a main raw material and various subsidiary materials, and using the same in a building to deodorize indoors. It is to provide functional cement terrazzo for building which can purify air environment, show antibacterial antifungal performance and increase far-infrared ray and negative ion radiation to provide beneficial living environment for human body.

According to the object of the present invention, secondary raw materials such as scoria produced by volcanic eruptions, illite minerals having photocatalytic properties, and pozzoranite minerals for activating the pozzoran reaction of cement to a cement terrazzo base constituent composed of cement and feldspar. A cement terrazzo is provided that has the functionality configured in a range of design quantities.

The functional cement terrazzo composition according to the present invention is about 18 to 25% by weight of general cement, 65 to 70% by weight of dolomite-based stones separated by particle size, 3 to 5% by weight of scoria minerals and 2 to 4% by weight of illite minerals. % And pozzoran are comprised from 3 to 5 weight%.

The functional cement terrazzo manufactured according to the manufacturing method of the present invention is a building flooring material used for building floors, such as a corridor of a house, a school, etc., and has an adsorption and decomposition performance of formaldehyde generated from adhesive or antiseptic wood. It provides a clean living environment with far-infrared rays and negative ions, and exhibits antifungal and antibacterial performance.

Hereinafter, the present invention will be described in more detail with reference to the following examples. However, the following examples are only for illustrating the present invention, and the scope of the present invention is not limited thereto.

Example

Production Example

In a powder mixer, approximately 220 kg of normal cement, 690 kg of dolomite-based stones with particle size control, 35 kg of scoria, 14 kg of illite, and 41 kg of pozzolan mineral are evenly mixed for 5 minutes at 60 revolutions per minute. 1,000 kg of a well-mixed mixture is wet mixed again with 120 kg of water and put into a mold of a constant size. After curing at about 6 hours at room temperature and then cured at 60 ° C. for 6 hours in a wet curing state, and curing at room temperature after curing for 12 hours. After curing, remove the molded part from the mold and polish the surface with a grinder.
