Description

Interior and exterior materials for building and manufacturing method thereof

The present invention relates to a building interior and exterior materials and a method for manufacturing the same, and more specifically, by mixing minerals such as sericite, chlorite, and other additives, which are acid salts, which exist as natural minerals, The present invention relates to a building interior and exterior materials and a method of manufacturing the same, which have a large amount of anion and far-infrared rays effect, deodorization and antibacterial effects, and are capable of preventing toxic neutralization, hardening, and cracking of cement.

In general, a method of attaching natural or artificial stone and cement mortar is applied to interior and exterior of a building.

When using the natural stone, artificial stone or mortar as an internal, exterior material is a situation that the use of cement is essential.

The cement is composed of a strong alkali, which emits toxic substances for a long time, and these toxic substances are not only bad wastes of residents living in concrete buildings, but also toxic substances generated from cement. Efforts to protect health from the abandonment of the situation are emerging as a social problem.

In the case of low temperature and high humidity of cement, the water-soluble components contained in the cement hardened body move to the surface and only water evaporates, causing whitening to precipitate whitening. Not only could it be maintained beautifully, but also the closed point such as lowering the strength of concrete was generated.

In particular, it is known that toxic components harmful to the human body are eluted during the process of whitening, and these harmful components eventually became a major cause of deteriorating the health of residents.

The present invention has been made in view of the above problems, and its purpose is to mix minerals such as sericite, chlorite, and other additives, which are acid salts, which exist as natural minerals, and have strong adsorption power and a large amount of minerals. It is to provide the interior and exterior materials of the building and its manufacturing method to have anion and far infrared effect, deodorization and antibacterial effect, and to prevent the toxic neutralization, hardening and cracking of cement.

Features of the present invention for achieving the above object, the step of collecting silicate minerals such as sericite, chlorite (S10); Dividing the collected minerals into coarse particles, respectively, selecting and removing impurities, followed by natural drying to dry the moisture contained in the epidermal layer of the mineral (S20); Putting the naturally dried minerals into a drying furnace and then applying heat at 600 to 750 ° C. to completely dry the moisture contained in the minerals (S30); Grinding the dried minerals finely and filtering the fine minerals into a fine powder having a particle size of 200 mesh (S40); Building comprising the step of making the building interior and exterior materials by uniformly mixing 41.9 to 48.2% by weight of mica powder, 33.8 to 36.3% by weight of chlorite, 9.9 to 12.1% by weight of aqueous adhesive, and 8.1 to 9.9% by weight of aqueous binder. It can be achieved by the manufacturing method of the interior and exterior materials.

As described above, the present invention, since natural minerals that emit anions in a natural state such as biotite and chlorite are added to the interior and exterior of the building, it can be neutralized by adsorbing the strong alkali toxicity of cement by the adsorption effect of fine particles of minerals. In addition, it can eliminate the toxic irritating odor of cement and at the same time, it can strongly reduce the hydroxyl group (OH-) ions of water causing hydration reaction with various components of cement by strong anion substitution ability of clay minerals. The toxicity of the cement can be further lowered, and the hardening and crack prevention of the cement can be prevented, thereby improving the overall durability.

The method is preferred because it allows mass production.

Of course, in some cases, it is possible to inject minerals into a rotary furnace that is mounted to be inclined and heated so as to dry them by heat.

Subsequently, each of the dried minerals was put in a grinder to finely pulverize, and then filtered through a sieve having a particle size of 200 mesh to prepare a biotite powder and chlorite powder (S40).

Subsequently, 5.4 Kg of biotite powder, 4.2 Kg of chlorite powder, 1.32 Kg of aqueous adhesive, and 1.08 Kg of aqueous binder were put in a general stirrer and mixed to complete 12 Kg of building interior and exterior materials, which is a mineral mixture (S50).
