TECHNICAL FIELD [0001] The present invention relates to a method for manufacturing an environmentally friendly coating material and an environmentally friendly method for coating the same. BACKGROUND OF THE INVENTION [0002]

The present invention relates to a method for manufacturing an environmentally friendly coating material and an environmentally friendly coating method, and more particularly, to a method for manufacturing an environmentally friendly coating material using natural dyes and a natural adhesive and an environmentally friendly coating method.

In the indoor interior construction, the demand for environmentally friendly building material and the well-being house interior using it is increasing, and the interest in environment-friendly building material is increased due to the construction material quality certification system and indoor air quality management law In order to meet various quality requirements, there is a demand for development of an environmentally friendly seedling which can solve the disadvantages of existing harmful liquid spoilage and powder pool.

In general, wallpaper is a product in which color and pattern are expressed through printing and embossing process after laminating two sheets of white paper, and it is widely used because it has relatively low unit cost and low construction cost. In the case of this laminated wallpaper, the laminated adhesive is used in the course of laminating two sheets of paper through the rollers.

Formalin and zinc chloride are used to improve the preservability and shade suitability of the existing gel-like spill for mariculture. In addition to safety hazards of the marbling ceramics, Causing volatile organic compounds to be released and causing controversy.

On the other hand, when the building is newly constructed, the cement poison that emits in the concrete curing process sprays toxic substances repeatedly by absorbing and discharging water for decades (30 ~ 50 years) curing period. When moving to an existing building, a new flooring material, wallpaper, and the like are newly installed. In the adhesive used in the process of constructing a wallpaper itself or wallpaper, a large amount of environmental hormones such as various volatile organic compounds are emitted.

Living in a space where these cement poisons or volatile organic compounds are released can cause or worsen atopic dermatitis or allergic dermatitis. There are various signs of physical abnormality such as headache, dizziness, numbness and dyspnea. This health disorder is called sick house syndrome.

Specific examples of such volatile organic compounds include formaldehyde, toluene, benzene, xylene, and the like. Formaldehyde is a volatile substance of formalin and is widely used for building materials and adhesives in houses. Compounds such as toluene, benzene, and xylene are harmful chemicals contained in paints and the like.

Thus, in order to block the harmful substances of the adhesive used in the manufacture of lumber and to respond to the interest of the people in human health or skin beauty, a functional material made of natural materials, such as volatile organic compounds, The research and development of grass is progressing steadily.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. The embodiments are provided to explain the present invention to a person having ordinary skill in the art to which the present invention belongs. Accordingly, the shape of each element shown in the drawings may be exaggerated to emphasize a clearer description.

FIG. 2 is a view showing an environmentally friendly coating method according to an embodiment of the present invention, and FIG. 3 is a photograph showing a cloth dyed with a natural dye according to FIG.

First, green dyestuffs are mixed with rice bran at a weight ratio of 7: 3, and then placed in a container (for example, Onggi) in which air is introduced and fermented for 1 week. During fermentation, rice bran with a C / N ratio of about 15, which is preferred for early fermenting microorganisms by the rice bran, and Bacillus that feeds on it first explosively increase to complete fermentation step.

Then, heavy stones (heavy materials) are placed on top of the contents in the container to pressurize the contents, thereby discharging the air in the rice bran mixed with the mugwort, and aging for about 6 months to assist the microorganisms.

Then, natural dyes are extracted from aged mugwort and rice bran, and centrifugation method can be used. The extracted natural dyes are mixed with rice hull ash and have basicity of pH 8 ~ 9. Natural dyes and rice hulls can be mixed at a weight ratio of about 6: 4.

Then, the dyed raw material is dipped in the dyed fabric and the dyed dyed fabric is repeatedly dyed (see Fig. 3).

On the other hand, the natural adhesive is mixed with rice and water at a ratio of about 1: 2 by weight, and is sufficiently bubbled and exposed to the air for aging for about 6 days. At this time, starch produced from rice is discharged together with water. The solid material (natural adhesive) obtained by naturally drying the precipitate (sticky material) obtained after repeating this process about 10 times is blended at a ratio of about 1: 1 with water at a ratio of 1: 1, Prepare a natural paste in a sticky state while slowly stirring for about 10 minutes.

Then, natural herbs (fruit and leaf) extracts are mixed in a weight ratio of 8: 2 to 7: 3 to obtain a natural adhesive excellent in antibacterial and antifungal properties. The natural adhesive is applied to the surface to be attached with the natural dyed silk cloth, and after that the silk cloth is attached and finished by natural drying.

Specifically, a flooring method according to an embodiment of the present invention will be described with reference to the following table.

division High functional wallpaper construction conditions Antimicrobial activity (%)
Up to 100 Antifungal (%)
Up to 100 Dye condition (pH) Natural paste manufacturing conditions (temperature) Conditions for producing antimicrobial grass (natural grass: sancho extract) Comparative Example 1 6 50 5: 5 90 90 Inventory 1 8 60 8: 2 98 99 Inventory 2 9 70 7: 3 100 100 Comparative Example 2 12 80 9: 1 80 85

● Anti-Fungal: Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus are cultured on a stomacher for 6 weeks and compared with high-function wallpaper. Number is 9 and the number of functional wallpaper generation is 1: 9: 1)

● Antimicrobial activity: the number of microbes generated in high-function wallpaper when receiving the highest grade of 6 weeks as 10 (sterile).

In case of pH 6 (acidic) of polyglycerol dye extract, it is not possible to obtain complete dyes because only the oxygen and binding oxidation occurs in the atmosphere because the triple fabric is immersed in the extract. It is not preferable because the surface of the triple rinse is damaged and the life is shortened. It is confirmed that when the basicity is weak with pH 8 ~ 9, the color is excellent as well as antibacterial and antifungal properties.

Natural glue extracted from rice for replacing chemical adhesive is mixed with rice and water at a ratio of 1: 2 and then exposed to the sunlight to decompose the starch in the rice at the stage of decomposition by microorganism during aging for 6 days After the process of discharging with water 10 times, the sticky precipitate remains finally.

The white solid prepared by drying the sticky material is mixed with water (solid content and water 1: 1) and heated under 50 ° C for 5 minutes in order to use it as a natural paste. The adhesive strength is lowered. When the adhesive is stirred for about 10 minutes at 80 DEG C or more, the stickiness of the adhesive layer is too high, which is not preferable because the uniform application property can not be obtained when pasting. On the other hand, it is possible to produce a natural paste which can obtain an optimum viscosity when stirring at a temperature of about 60 to 70 degrees for 5 to 10 minutes, so that it is easy to spread through uniform application at the time of pouring.

It is a method to add antimicrobial and antifungal properties to natural grasses. It is formulated with 8: 2 ~ 7: 3 extracts of natural grasses and acanthopanax among plants. Agitation is slowly mixed for 2 ~ 5 minutes to obtain excellent antimicrobial and antifungal properties A natural adhesive is prepared. The ratio of the natural grass to the pickled acacia seed extract was adjusted to 8: 2 or less to 5: 5, and the mixture was stirred. In the analysis, the antimicrobial and antimicrobial properties of the natural herb extracts were lower than those of the natural herb extracts. When the natural herb extracts were mixed with the herb extracts at a ratio of 8: 2 to 7: 3 for 2 to 5 minutes, It can be confirmed that anti-moldiness is obtained.

FIG. 4 is a photograph comparing the results of the antimicrobial analysis sample. The left side of FIG. 4 is the analysis result of the sample according to the inventive example, and the right side of FIG. 4 is the analysis result of the sample according to the comparative example. The left side of FIG. 4 shows no reaction to the bacteria due to the high antibacterial property, whereas the right side of FIG. 4 shows the reaction to the bacteria.

Fig. 5 is a photograph showing the result of the anti-fungal assay sample, and the result of analysis of the sample according to the invention. As shown in the left side of FIG. 4, it can be seen that a high antifungal property does not cause a reaction to the mold.
