Description

Pollution prevention stone using functional bio-ceramic and its manufacturing method {POLLUTION CONTROL SURFACE STONE USSING BIO-CERAMIC PRODUCT}

The present invention relates to a method for forming a stone surface anti-fouling film using a functional bio-ceramic, and more particularly, spray coating or coating a functional bio-ceramic solution on a stone surface installed on an exterior wall of a building, or by applying a brush to form a anti-fouling film on a stone surface. Later, by attaching the stone to the outer wall of the building, even if contaminants are attached to the surface of the stone exposed outside the building, it is easily washed in the rainwater and the cleaning cycle is lengthened, and the latex penetrates into the stone from the silicon medium installed between the stone. The present invention also relates to a method for forming a stone surface contamination prevention film using a functional bioceramic which prevents black contamination of the stone and additionally deodorizes due to intrinsic cement toxicity removal, anion and far infrared generation.

In general, the construction method of stone attached to the exterior wall of the building is to apply cement mortar to the concrete of the building, and then attach the stone so that the cement mortar acts as an adhesive to fix the back of the stone and the concrete surface. When the wet construction method was performed a lot, the time after the construction of the stone has a disadvantage that the stone falls due to the shrinkage of cement mortar, the expansion coefficient and the shrinkage of the stone, the expansion coefficient is different.

Therefore, in order to remedy these unreasonable points recently, after weaving the frame of the steel angle mesh net form, the frame is fixed to the concrete building with anchor bolts for concrete, and holes are formed in the angle of the frame structure and the stone is placed in the angle of the angle. "The dry stone construction method using a magic method that uses a medium method to fix the stone by inserting an iron pin between the hole of the angle and the hole of the stone surface after placing it on the shape clamp is used a lot. have.

In this dry stone construction method, the stone plates are fixed to the angle frame by 2 ~ 5cm away from the outer wall of the concrete building, so that the space between the stone and the building buffers even if there is some shaking of the building due to earthquakes. This occurs less often, and the space layer between the stone and the building serves as a waterproof and thermal insulation.

However, the conventional dry stone construction method has a problem such that the oil component of the silicone waterproofing material which is treated for the waterproofing between the stone and the stone is absorbed into the stone and the constructed stone is contaminated black.

In order to solve the problems of the prior art as described above, the antifouling stone using the functional bio-ceramic according to the present invention,

Stone and functional bio-ceramic is applied 0.1 to 0.5mm on the surface of the stone is characterized in that the anti-fouling film is formed.

5 steps of aging the resultant of the 4 steps for 20 to 30 hours;

The functional bioceramic manufactured through the above five steps is sprayed or painted on a part or whole of the surface of the stone by forming a pollution prevention film by six steps.

Herein, the inorganic binder (Inorganic Binder) refers to an inorganic binder strictly, and is an inorganic adhesive. Inorganic binders include cement (portland cement), gypsum mainly composed of calcium sulfate, mud or clay, sodium silicate as liquid, alumina silicate, calcium silicate and the like.

As described above, according to the present invention, by installing a functional bio-ceramic on the stone surface to form a pollution prevention film on the building outer wall, even if contaminants are attached to the building outer wall, it is easily washed away by rainwater, and is filled between the stone and the stone. The latex from the treated silicon does not penetrate the stone to prevent black contamination, as well as to remove formaldehyde, the causative agent of sick house syndrome, which occurs in buildings.
