The present invention relates to a thin coating material composition using a natural mineral pojoran and a method for manufacturing the same, and more specifically, it can be applied to both a thin coating such as paint on the concrete surface to a thick coating such as mortar, interior finishing materials When used as a neutralizer, it can neutralize cement poison, remove cement dust, purify indoor air with excellent antibacterial and deodorizing effect, and it can maintain healthy life because it emits beneficial energy to human body by releasing far infrared rays and anions. It relates to a pojoran coating material composition and a method of manufacturing the same that can be applied to the waterproofing and plastering effect when outdoors.

The Pojoran mineral is a Cretaceous igneous rock of about 100 million years ago. It has excellent acid resistance, corrosion resistance, heat insulation, durability and waterproofness. Historically, many buildings such as the Pantheon in ancient Greek Rome were built as Pojoran and have been built for over 2,000 years. Boasts its robustness. Korea's only Pojoran mine in Hoengseong-gun, Gangwon-do, has excellent antibacterial, deodorant, water purification and detoxification effects. In particular, it contains a large amount of trace elements and organic matter, which is beneficial to the human body, and is used as a cosmetic and high-grade building material.

Until now, most of the living spaces have been finished with gypsum board, plywood, paint, and wallpaper using concrete as the main material, which has been reported several times in the mass media, thus releasing various harmful substances. Syndrome) is the main culprit.

Moving into a new building releases an irritating odor that hurts the head. Among these volatile organic compounds (VOCs), benzene (Benzene) is carcinogenic and respiratory irritant. Xylene) causes anesthetic irritation, heart, liver, stomach, and nerves. Toluene causes anesthesia and anemia, and Stylene may cause anesthesia and central nervous system abnormalities. Warning you. In addition, ethyl benzene causes strong irritation to the eyes and respiratory system and central nervous system disorders, and dichloromethane causes red blood cell growth, anesthetics, and central nervous system disorders, and tetrachloroethylene. ) Is classified as a substance with a high risk of abnormalities in the nervous system of the stomach and is designated as a specific harmful substance by the Ministry of Environment in Korea.

In new buildings, formaldehyde or acetaldehyde is a harmful gas produced by the oxidation of methyl alcohol or ethyl alcohol and continues to be released for 4 to 5 years. Many people living in offices or apartments in newly constructed buildings complain of coughing, stuffy nose, and asthma, but this is also recognized as a major cause of chemicals in the air.

In particular, research results that the cause of allergic rhinitis is due to formaldehyde in the room air is attracting attention. Formaldehyde has been designated as a poison declared by the Ministry of Environment. In addition, although it is a chemical substance having high toxicity and environmental hazards at the same time, although it is widely known as a carcinogenic substance, it is a pity that there is no indoor environmental standard for harmful gases in the country until now.

As a solution to harmful substances emitted indoors, it is easy to think of how to discharge pollutants by deliberate ventilation or to install an air purifier for controlling VOCs, but it is often not practical and expensive to operate and install. There is a problem such as occurs, and there is a disadvantage that it is not a fundamental solution to block the harmful substances.

In addition, there are products using minerals such as ocher, illite and zeolite, but it is difficult to solve the problem of new building syndrome because there are many parts that are difficult to trust the efficacy depending on the origin and type of mineral.

Therefore, the object of the present invention is to neutralize the cement poison, block the cement dust, and excellent adsorption capacity for volatile organic compounds (VOCs) generated in the room, and to promote the human indoors by far infrared emission to accelerate the pleasant indoor environment In addition, it has the purpose of providing a pojoran coating material composition having good field workability.

In order to achieve the above object, the pojoran coating material composition of the present invention is 100 to 400 mesh (porous) pojoran powder in 100 parts by weight of dry curable polyacrylic emulsion resin or polyethylene vinyl acetate emulsion resin 5.0 to 35 parts by weight, dispersing agent or wetting agent 0.1 To 2.5 parts by weight, 0.1 to 1.0 parts by weight of a water-soluble thickener, 0.01 to 0.02 parts by weight of a preservative to form a coating material composition, characterized in that the composition is prepared using a ball mill.

The above object of the present invention is to neutralize the cement poison, block the cement dust, excellent absorption of harmful substances generated in the room, improve the activity of the human body by far-infrared radiation to create a comfortable indoor environment, good construction properties Pojoran to provide a coating composition.

Hereinafter, the present invention will be described in detail.

<Example 1> The characteristic of the pojoran mineral of this application;

Rocks were purchased from the Pojoran mine in Hoengseong, Gangwon-do, and crushed through a jaw crusher, a ball mill, and an atrium mill, and powdered using a sieve. Elements contained in the pojoran mineral used in the present invention are shown in Table 1, electron micrographs are shown in Figure 1. This result is the analysis result of Korea Testing and Research Institute.

<Example 2> Pojoran thin coating material composition preparation;

Pojoran powder of 100 mesh and 400 mesh were mixed in a weight ratio of 1: 1, and each of 100 g of the mixed pojoran powder was measured and classified into six samples.

To this, 5, 20, and 35 g of emulsified polyacrylic resin and polyethylen vinyl acetate resin were added, respectively, and NP-10 (Nonyl phenol 10 mole) was added as a surfactant of a dispersant and a wetting agent, 0.1, 1.0, 2.5 g, 0.1, 0.5, 1.0 g of water-soluble thickener of Hydroxyethylcellulose, 0.05, 0.1, 0.5 of antifoam of silicone series, and 0.01, 0.02 g of methylparaben, respectively, were added as preservatives. After supplying an appropriate amount of water in accordance with the application of the coating material it was rotated in a ball mill for 2 hours to obtain a coating material composition.

The ball mill used here used an alumina (Al 2 O 3) ball having a diameter of 10 mm.

The Pojoran coating material composition was applied to the concrete floor using an earth knife at an average thickness of 10 mm, and the concrete specimen was applied using a brush at an average thickness of 1.0 mm, and the surface condition was observed after one week.

As the amount of emulsified polymer resin contained in the pojoran coating material increased, the adhesion was excellent. In the case of acrylic resin, the hardness was greater than that of ethylene vinyl acetate resin, and the waterproofing and water resistance were strong. In the case of ethylene vinyl acetate resin, the film was flexible, so there was no crack. Since the size of the emulsified particles was small, it penetrated the coated surface well, and the mutual safety related to adhesion with the concrete surface was excellent. The dispersibility and flowability were slightly different according to the amount of dispersant and the wetting agent, the rotation speed and the time of the ball mill, and 1.0% of the dispersing agent and the wetting agent and 50 minutes of the ball mill showed the optimum conditions. In the case of using a surfactant used as a dispersant and a humectant, even when the silicone-based antifoaming agent was added up to a range without foaming regardless of the amount of the surfactant, there was almost no change in physical properties.

Therefore, the amount of water and water-soluble cellulose must be properly adjusted according to the condition of the coated surface and the use of the pojoran coating material. The amount of cellulose is 0.1 parts by weight and the preservative is effective in 0.01 parts by weight of methylparabine. I could confirm it.

In addition, the comparison of hydrogen ion concentration between concrete wall and pojoran paint showed that the average pH of the concrete wall was 11.6, and that of pojoran paint showed an average pH of 7.9.

<Example 3> Physical and chemical experiment of this invention;

For the investigation of the suitability of the material as a functional finishing material, the Barimjae of this application produced a sample and commissioned the experiment to an accredited certification body such as Korea Institute of Construction Materials and Korea Living Environment Testing Institute, and the results are shown in [Table 2] to [Table 6].

<Example 4>

In order to confirm the deodorizing effect of Pojoran paint by measuring the adsorption and removal ability of harmful gas, the difference between indoor air and the site where the Pojoran paint was installed in the new apartment building and the site where Pojoran paint was applied was measured and the result Table 7 shows the change in concentration after a certain time using gas chromatography (head space method) to measure the adsorption and deodorization effect of the harmful gas of pojoran paints. After injecting 2 g of ash and a solvent, the temperature was raised to 70 ° C., and the concentration of the gas was measured by GC at an interval of 1 hour while the solvent was vaporized. The analysis conditions of GC were FID detector and 30m capillary column was used to isolate analytes. The temperature of injector, oven and detector were set to 100 ℃, 60 ℃ and 200 ℃, respectively. The results of this experiment are shown in [Table 8] and the emission concentration changes of the harmful gases over time are measured and the results are attached to [Figure 2].

When finishing the interior of the building with Pojoran paint using natural mineral Pojoran powder instead of conventional wallpaper or paint, the adsorption rate of odor and harmful gas contained in the indoor atmosphere is very good, and it neutralizes the cement poison and dust. It has been found to have a beneficial effect in suppressing the occurrence and maintaining a healthy life of the human body by far-infrared emission without inhibiting other physical and chemical properties.
