Description

Construction Material with Quartz Porphyry and Preparation Method Thereof}

The present invention relates to building interior and exterior materials, and more particularly, to a building interior and exterior materials and a method for manufacturing the same, which is prepared by mixing elvan and adhesive and pressing it at high pressure.

Recently, with the development of industry and abundant living, there is a growing interest in improving the quality of life. In keeping with these trends, modern people want to change their living environment to be more environmentally friendly. As a part of such a method, the far-infrared rays, which are beneficial to the human body, are released, and elvan is equipped with antibacterial and deodorizing functions, and has been used as interior and exterior materials for construction.

The above-described quartz porphyry (Quartz Porphyry,麥飯石) is by the appearance of rock like a barley grain as an off-white ttuin Ansan porphyry is referred to in this manner, components of the quartz porphyry is _{Ge, SiO 2, Al 2 O} 3, Fe 2 O 3 , CaO, MgO, K ₂ O, NaO, TiO ₂ , P ₂ O ₅ , MnO, TiO ₂ , P ₂ O ₅ , MnO, etc., The ingredients are rich in minerals and minerals beneficial to our body Its use is expanding day by day.

On the other hand, the ganbanite has been used a lot since ancient times, mainly when the tablets were used as anti-inflammatory agents in various skin diseases such as filter media, canopies, boils, etc. Food, cosmetics, toothpaste, fish farm, wastewater treatment, deodorant, plant growth accelerator, medicinal preparation, sauna facility, far-infrared radiator manufacturing material, electromagnetic wave through research on strong adsorption, mineral precipitation, water quality control, dissolved oxygen in water It is widely used for barrier materials, interior and exterior materials of buildings.

However, when the above-described bar stone is used as a building interior and exterior materials such as flooring, interior walling, etc., it should be manufactured in a series of shapes in consideration of problems such as aesthetics and easy installation, and is made of brittle grains of barley rice. There is a problem that it is not easy to use, and even if the house-molding is easily broken, it is difficult to use for interior and exterior building materials.

For the purpose of solving this problem, Korean Patent Publication No. 1999-0054102 discloses lamination of Hanji and finely ground gantheum powder in order to form a certain thickness, and cut it to a certain shape to complete the living room or room It describes a sheet of cardboard adhered continuously to the bottom of the back, and Korean Patent Registration No. 300453 powders a certain amount of elvan, mica and white clay into 300 mesh, respectively, to defensive sedimentation and to remove iron and foreign substances. Powdered oak charcoal of 200 mesh and diluted with water to prepare oak charcoal, and the powdered elvan, mica and white clay are mixed with the oak charcoal to make a mixture, and then a method of preparing a finish by adding an adhesive is described. And, Republic of Korea Patent Registration No. 301365 is a crushed bar stone, predetermined plaster plaster, plaster retardant, natural It describes a dry mortar containing gannstone as a main raw material mixed with a mixed gypsum composed of gypsum and anhydrous gypsum.

On the other hand, as another method of manufacturing a building material using the above-described bar stone, European Patent Publication No. 1132445 finely grinds and powders the stone generating far infrared rays or negative ions, and powdered stone powder on the surface of the building material A method of adhering with an adhesive is disclosed.

The above-mentioned methods are used to prepare the interior and exterior building materials including ganban stone by grinding the ganban stone into fine powder and then mixing the ground ganban stone powder with an adhesive or the like, or by adhering to the surface of the existing building interior and exterior materials to obtain the function of generating the efficacy of ganban stone. I'm trying to.

However, in the case of the fine powder, it is difficult to mold, and because of the difficulty in forming, it is used to adhere to the surface of the building interior and exterior materials, but increasing the content of ganban stone in order to increase the function of ganban stone, the physical properties of the building material deteriorates In the case of silicon contained in, it is difficult to add more than 40%. In addition, since the elvan is made of fine powder, the amount of far-infrared radiation is low, and the deodorizing and antimicrobial effects are reduced.

Particularly, since the rock is not formed in large chunks like ordinary rocks, it is formed as a vein, so it is unreasonable to be used as interior and exterior materials for construction, and it is commercialized as a functional mortar material, but this is also cracked after solidification due to the characteristics of the rock. ) Is not aesthetically pleasing, and because of the finishing and delamination, there is a problem such as blocking the effect of elvan rock such as far-infrared radiation.

The present invention was derived to solve the above-mentioned problems, it emits a sufficient amount of far infrared rays, has antibacterial and deodorizing performance, high temperature conductivity, heat preservation time for a long time beneficial and comfortable living environment The technical challenge is to provide interior and exterior building materials that can provide.

In addition, the present invention has a technical problem to provide a method for manufacturing interior and exterior building materials, including pressing a high-pressure after mixing a certain size of ganban stone particles and the adhesive that is not ground into a powder.
