Abstract
The present invention relates to an eco-friendly wall finishing composition, and more particularly, to an eco-friendly wall finishing composition which is excellent in water resistance and durability and has excellent properties such as air shortening, crack prevention, radioactive element Release suppression effect, and the like.
Description
More particularly, the present invention relates to a wall-finishing composition, which is excellent in water resistance and durability and has a shortening of air, a deodorizing effect, release of radioactive elements, and the like by using P. agalmatolite and Ethylenevinyl acetate (EVA) To an environmentally friendly wall finishing composition excellent in suppressing effect.
Generally, most of the wallpaper used for interior wall finishing is generally made of vinyl chloride wallpaper. Such wallpaper contains a large amount of formaldehyde by containing a large amount of organic chlorine compound, a phthalic acid compound-containing plasticizer used in the manufacturing process, an adhesive containing formalin, and the like.
Studies have also been conducted to replace wallpaper with wall liners. However, since synthetic resin emulsions are still used as binders, compositions containing such synthetic resin emulsions contain volatile organic compounds (VOCs) due to the presence of unreacted monomers in the emulsion And can cause chemical sensitization.
Most of the currently marketed wall liners are made by adding synthetic mineral emulsions as binders and minerals such as elvan, jade, yellow soil, and ilite to add bio-properties. Since such a conventional wall lacquer uses a general synthetic resin emulsion, it is difficult to block the volatile organic compounds.
In order to solve the above problems, Korean Patent Registration No. 10-0635334 discloses a wall-wicking composition using a natural protein-based resin as a binder without using a conventional synthetic resin emulsion, and Korean Patent Registration No. 10-0591932 Discloses an eco-friendly mineral bio wall building material composition which uses slaked lime as a main binder material and a latent hydraulic pozzolanic material as an auxiliary binder, unlike the existing synthetic resin wall lumber material.
However, the natural protein based resin and the slaked lime used in the above literature have a problem of mixing during the production of the wall finishing material composition, requiring a long operation time, causing bubbles and damaging the appearance of the product, and the cost is high.
In order to solve the above-mentioned problem, Korean Patent Laid-Open Publication No. 10-2014-35614 discloses a method for manufacturing a glass sheet, comprising: (S1) hot-pressing a glass paper layer and a printing sheet layer using a PVC sol; (S2) forming a print layer for forming a pattern on the print sheet layer after the step (S1); Stacking the PLA transparent film layer (S3) after the step (S2); And embossing (S4) embossing on the PLA transparent film layer, and a wall finishing material produced by the method.
By using the PLA of the product, the above-mentioned wall finishing material is excellent in biodegradability, easy mixing of raw materials, can achieve three-dimensional steric effect, and is expected to prevent environmental pollution. However, since the PLA (poly lactic acid) resin is a lactide or a thermoplastic polyester of lactic acid, it must be prepared by polymerizing lactic acid produced by fermenting starch extracted from plant resources such as corn and potatoes. Therefore, It is difficult to depend on imports. Therefore, it is practically difficult to mass-produce the wall finishing material composition, and there is no effect of suppressing the emission of far infrared rays such as radon.
Accordingly, there is a need to develop an eco-friendly wall finishing composition which is excellent in water resistance and durability and is excellent in shortening of air, deodorizing effect, and emission suppressing effect of radioactive elements compared with conventional wall finishing materials.
It is an object of the present invention to provide an eco-friendly wall finishing material which is made of pyeondong pyroxene and ethylene vinyl acetate as main components.
The eco-friendly waterproof finishing material according to the present invention is simple in construction, excellent in water resistance, and environmentally friendly.
In order to solve the above problems,
45% by weight of Pyeongchang gypsum, 45% by weight of ethylene vinyl acetate and 20% by weight of water as the main means for solving the problems.
In order to solve the above-mentioned problems, the eco-friendly wall finishing material of the present invention comprises 5 to 20 parts by weight of sericite and 100 parts by weight of pyrophosphoric acid, ethylene vinyl acetate and water, 10-15 parts by weight of tourmaline; 10 to 30 parts by weight of a polyvinylidene fluoride resin; 0.5 to 3.5 parts by weight of ethylene glycol; And 0.1 to 2.5 parts by weight of a natural mineral inorganic antibacterial agent.
The wall finishing composition of the present invention is advantageous in that the drying time is shortened, the drying time is shortened, and the generation of bubbles is suppressed when the raw materials are mixed.
In addition, it has excellent durability because it is waterproof and flexible in walls and prevents cracks. At the same time, Pyeongchang Pyrex is excellent in blocking radionuclides such as radon, so it is harmless to the human body and works in airtight space. Do.

Pyrophyllite is a generic term for pyrophyllite as rock or ore, pyrophyllite is pyrophyllite minerals, and rhyolite is formed mainly by hydrothermal alteration of rhyolitic tuff or oresite. The pyrophyllite or rhyolitic pyroxene of rhyolitic tuffaceous rocks is classified as sericite pyrophyllite.
Pyeongchang pyroxene (P. agalmatolite) is pyrophyllite collected in Pyeongchang area, Gangwon province, and there are many kinds such as white or pale brown, and the surface of dense amorphous (amorphous) is like a stone. Depending on the type of main constituent minerals, it is divided into seaweed pyrophyllite (Leaf quartz diapore kaolin kaolin mining sericite), aged kaolinite (kaolinite diketite quartz diaspore baemite) and sericite pyroxene (sericite quartz kaolinite). Rhyolite, andesite, and quartz porphyry were formed by hydrothermal alteration.
Since P. agalmatolite is relatively low in moisture content, it can be used directly without shamotte formation, and is easy to crush as a denatured mineral. In addition, P. agalmatolite can be used as a barrier against far infrared rays and radioactive materials It has excellent effect and contains a large amount of minerals. Therefore, it can be used as fertilizer additive, drinking water treatment agent, aquaculture feed as well as building finish material such as refractory brick and mortar.
Ethylenevinyl acetate (EVA) was originally developed as EVA (Ethylene Vinyl Acetate) by newly introducing VA (Vinyl Acetate) into the existing properties of LDPE (Low Density Polyethylene) in IC1 of England in the 1930s.
EVA is a term used to refer to a copolymer of ethylene and VA. It is generally used to refer to a copolymer in which VA is randomly polymerized in the backbone of polyethylene. Therefore, the basic properties of EVA can be explained according to the content of VA because the properties are basically depending on the nature of LDPE and VA. For example, when the content of VA is increased from 5% or less to 30%, crystallinity, melting point, flexibility, clarity, solubility, and EVA The diffusion rate of the low molecular weight is significantly changed.
The above-mentioned EVA is very advantageous for filler loading, and it does not deteriorate physical properties when it is mixed and crosslinking is easy. Therefore, the production of semi-conductive or jacket of wire and cable and transparency, It is used in films, sheets, medical pouches, stretchable bags, bag-in boxes, etc. due to characteristics such as scratching (self-sticking) and low sealing temperature.
In addition, a transparent polymer sealant is used to completely adhere the cell, glass, and back sheet to the PV module and to completely block the cell from moisture and dust. In the encapsulant used in the PV market EVA, which is superior in transparency and toughness, is the most widely used, and is mainly used for automotive soundproofing and sound absorbing materials due to its unique flexibility and thermoplastic form.

The amount of the sericite to be added is preferably 5 to 20 parts by weight relative to 100 parts by weight of the pyrethroid pyroxene, ethylene vinyl acetate and water.
The finishing composition of the invention may also comprise tourmaline for the generation of anions. Tourmaline, also called tourmaline, has a crystalline structure of cycloborosilicate, which generates heat that is beneficial to the human body when subjected to heat or pressure. Such tourmaline is said to generate 2,000 anions per cc in the natural state. Anions absorbed into the body are absorbed at a rate of about 18% from the respiratory tract and about 82% from the skin. These anions detoxify active oxygen, weakly alkalize body fluids, and purify the air. These anions emit 250 per 1 cc in natural or polluted air, and about 2500 to 3800 per cc in the forests of forests and waterfalls. As described above, it is known that tourmaline generates negative ions and far-infrared rays, maintains deodorizing effect and freshness of food, and has a water purification effect.
The tourmaline is preferably 10 to 15 parts by weight relative to 100 parts by weight of the pyrethroid pyroxene, ethylene vinyl acetate and water.
Also, the present invention can add a polyvinylidene fluoride resin to prevent the cohesive force of the wall finishing composition and the separation of the material.
