Description

An environment-friendly wall coating material with Pseudomonas pseudolite (P. Agalmatolite)

The present invention relates to a viscose material, and more particularly to a pesticide composition which is excellent in water resistance and durability and has a shortening effect on air, a deodorizing effect, and a suppression effect on the release of radioactive elements, by using Pseudomonasporin (P. Agalmatolite) and Ethylenevinyl acetate It is about excellent environmental friendliness.

Recently, as the importance of living environment has been getting more important as the quality of life and interest in well - being have increased, the problem of indoor environmental pollution has recently been pointed out as the biggest concern.

In the modern world, in the 1970s, energy conservation of various buildings including buildings was carried out in order to reduce energy use and increase efficiency due to the rapid increase of oil prices due to two oil shocks in the world in the 1970s. By airtightness or sealing windows or crevices, the loss of cooling and heating to the outside air is minimized, the heat loss through the wall is reinforced by the insulation, and the sealing of the building using the method to prevent condensation inside the insulation is increased .

In countries where high industrial growth has been made as in Korea, the increase in chemical harmful emissions brought by industrialization is proportional to the degree of air pollution in the rooms due to various chemical materials used in the construction process of the buildings.

As large-scale residential facilities such as energy-saving buildings and apartments become common, they are used for construction of many chemical materials including cement, so that quick construction and convenient construction methods are pursued. Bond-like adhesives are used for wallpaper and floor boards. Formaldehyde I made furniture with a lot of wood, and my house was full of various chemicals. In addition, indoor environment pollution due to enclosed environment where bad air can not escape by installing double glazing for indoor heating has recently emerged as a new environmental problem in urbanized areas.

Recently, attention has been focused on cement and concrete materials as well as simple structural aspects and environmental aspects.

Houses and buildings built in the urban form of modern society emit indoor pollutants such as asbestos, formaldehyde and other particles, stimulating the eyes, nose and throat of the human body, causing headaches and dizziness, do. It also causes allergic diseases such as asthma, rhinitis and atopy, acute pneumonia, and high fever. The health problems and discomforts experienced by residents in the building are called sick house syndrome or building syndrome.

The development and application of environmentally friendly inorganic coatings to solve the problem of sick house syndrome caused by formaldehyde and organic volatiles generated in various interior materials of the indoor space are becoming active.

In general, the inside of a building is painted with a general coating material such as paint or a cement mixture to improve weatherability, corrosion resistance, chemical resistance or to form a beautiful surface. Conventional wax materials related to this technology use organic materials whose main raw materials are synthetic resins for various paints such as waxy resin, alkyd resin, and acrylic resin. These waxes are dissolved in water or dissolved in organic solvents And what is soluble in water is called water-soluble, and what is dissolved in organic solvents is called oil-based.

However, such an organic waxy material as described above does not have elasticity in accordance with temperature changes, such as steel products, concrete structures, copper structures, etc., which are in contact with the outside air in spite of their water and oiliness, and they are cracked and peeled Rust and so on.

In addition, the organic varnish has fluidity or toxicity due to mixing, which is a cause of allergy and has become a serious problem of safety and air pollution.

As described above, the specific problem of the organic wax is that it can not be solved by using the organic wax, and it is possible to replace the synthetic resin for the paint used as the main component of the organic wax or to use the inorganic wax with the inorganic material of the hydraulic wax as the main component .

More specifically, the eco-friendly visor includes 40% by weight of pyrethroid pyrophyllite, 40% by weight of ethylene vinyl acetate, and 20% by weight of water.

The Pyeongchang pyroxene (P. Agalmatolite) is a pyrophyllite collected in Pyeongchang area, Gangwon province, and there are various kinds such as white or pale brown color. The surface of dense amorphous (amorphous) is like a stone. Depending on the type of main constituent minerals, it is classified as lobstable pyrophyllite (lobster quartz diapore kaolin kaolin mineral sericite), aged kaolinite (kaolinite diketite quartz diaspore baemite), sericite pyrophyllite (sericite quartz kaolinite) And rocks such as andesite and quartz porphyry were formed by hydrothermal alteration.

Since P. agalmatolite has a relatively low moisture content, it can be used directly without shamotte formation, and is easy to be crushed as a denatured mineral. In addition, P. agalmatolite can be used as a blocking agent for far infrared rays and radioactive materials And it contains a large amount of minerals. Therefore, it can be used as fertilizer additive, drinking water treatment agent, and aquaculture feed as well as a building finish material such as refractory bricks and mortar.

The eco-friendly visor is prepared by mixing water with the pyeondang dolomite and ethylene vinyl acetate (EVA).

The eco-friendly wax can also be classified into a composition for undergarment and a composition for topical application.

The environmentally friendly varnish for paddy was prepared by mixing 40 wt% of Pyeongchang pyrophyllite, 40 wt% of ethylene vinyl acetate and 20 wt% of water, and the topping padding material was composed of 35 wt% Pyrethrum pyrophyllite, 35 wt% ethylene vinyl acetate, %.

The size of the pyrethroid gypsum particles used for the undergarment wick is 150 to 250 mesh, preferably 200 mesh.

The pyrethroid gypsum particles used for the topsheet material are characterized by having a size of 325 to 500 meshes.

The eco-friendly wax may include sericite, zeolite, ethyl cellulose, and titanium oxide. When the sericite is added, the durability, environment-friendly effect and coloring effect of the wax can be further improved. The added sericite may be added in an amount of 5 to 20 parts by weight based on 100 parts by weight of the pyrethroid pyroxene, ethylene vinyl acetate and water.

The eco-friendly wax was prepared by mixing 15 parts by weight of sericite, 10 parts by weight of zeolite, 10 parts by weight of ethyl lactate, 100 parts by weight of a mixture of 40% by weight of pyrophyllite pyrophyllite, 40% by weight of ethylenevinylacetate and 20% 1.5 parts by weight of cellulose, and 25 parts by weight of titanium oxide.

Preferably, the organic thickener is selected from the group consisting of cellulosic ether, ethylcellulose, polyvinyl alcohol and the like, and 0.5 to 2.5 parts by weight based on 100 parts by weight of the mixture of pyrethroid, ethylene vinyl acetate and water.

In order to improve the coloring property, titanium oxide may be contained in an amount of 1.5 to 4.5 parts by weight based on 100 parts by weight of the mixture of pyrethroid, ethylene vinyl acetate and water.

The method of manufacturing the eco-friendly wax will be described in more detail.

Unlike the existing Pyeongchang pyroxene, Pyeongchang pyroxene is suitable for environmentally friendly paints because it does not contain environmental pollutants.

Pyeongchang-pyroclastics obtained from Pyeongchang, Gangwon Province are crushed in crusher and crushed to a particle size of 100 to 1,000 mesh in a jet mill precision crusher. Further, only particles corresponding to 150 to 500 mesh are selected through the following powder mill, and then ethylene vinyl acetate and water are mixed with the above-mentioned weight ratio, and the mixture is stirred in a mixer at a temperature of 1,000 to 1,800 rpm for 30 minutes. When the above-mentioned various additives are added in an amount as described above in the stirring process as needed, a viscose including durability, anion generation, cohesion, bubble suppression effect and antibacterial effect can be produced.
