The present invention relates to a method for manufacturing furniture using an environmentally friendly paint composition, and more particularly, to prevent the generation of environmental pollutants by applying a paint mixed with an environmentally friendly paint composition and silver nano to furniture, instead of paint containing chemicals. And it relates to a furniture manufacturing method using an environmentally friendly paint composition to generate anions and have a sterilization function by silver nano.

As the quality of life has recently improved, interest in the environment has increased, and the concept of cleanliness of indoor air has emerged, and the human body has been proved to be harmful by human harmful substances generated from various interior finishes. In order to solve the problem that is problematic, environmentally friendly and harmless paint products as interior finishing materials are required.

Most building materials used indoors contain hazardous chemicals. In particular, as the use of building materials containing chemicals increases in terms of mass production and cost, the environment of indoor air quality is worsening. In recent years, the trend of building materials has been demanding materials that are human-friendly, possess new functions, show multifunctionality, and maximize their effectiveness.

In particular, in the case of architectural paints, new physical properties are required in terms of color, smell, and human benefits (antibacterial, deodorant, far-infrared, anion, etc.) in accordance with the modernization and human-friendly elements of buildings.

That is, not only the function of the building exterior wall protection function and exterior decoration of the conventional paint, but also the odorless, environmentally friendly, and multi-functionality that is beneficial to the human body is required. In particular, the domestic paint industry is one of the representative pollution industries that occupies a huge environmental pollution load of 50% of the total emissions of domestic volatile organic compounds (VOCs).

In order to escape from such indoor pollution, the Ministry of Environment has established the Indoor Air Quality Control Act, and is taking measures to regulate toxic organic compounds (VOCs) for paints used indoors. Among them, volatile organic compounds (VOCs) and formaldehyde are focused on them. It is prescribed | regulated as phosphorus measurement item. Accordingly, the domestic market of eco-friendly paints is growing, and the demand for eco-friendly ceramic paint products is increasing in line with the growing trend of eco-friendly paints imported from Germany and the United States.

The present invention is to solve the problems as described above, the object of the present invention is to apply a paint containing a mixture of environmentally friendly paint composition and silver nano to furniture, instead of paint containing chemicals, to suppress the generation of environmental pollutants An object of the present invention is to provide a method of manufacturing furniture using an eco-friendly paint composition that has anion and sterilization by silver nano.

Therefore, the present invention has been made to solve the above object, the furniture manufacturing method using the eco-friendly paint composition according to the present invention, the step of polishing the surface of the furniture (S1) and the eco-friendly paint composition 80wt% (S2) and coating the surface of the furniture with a mixture of 20 wt% silver and silver (S2), drying in a natural state for 2 to 3 hours (S3), and regrinding the surface of the furniture with sanding paper after drying ( S4), the step (S5) to draw a halfway painting with a patterned roller on the polished furniture surface, the step of drying the above-mentioned midway painting (S6), the paint mixture of 80wt% and 20wt% silver nano It is characterized by consisting of a step (S7) and a step (S8) of drying the coating on the surface of the figure.

According to the furniture manufacturing method using the eco-friendly paint composition of the present invention as described above, by mixing the eco-friendly paint composition with silver nano to the surface of the furniture, in a large amount of volatile organic compounds (such as formaldehyde) such as various adhesives and paints It is effective in preventing the occurrence of environmental pollutants generated, and having anion generated and sterilized by silver nano to prevent allergic diseases.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

1 is a block diagram showing a furniture manufacturing method using an environmentally friendly paint composition according to the present invention.

First, the production of paint solvents for the reduction of formaldehyde content and volatile organic compounds (VOCs) content will be described.

In order to solve the problems including formaldehyde and harmful substances generated in the materials used in the resin polymerization process or paint mixing process, first, a surfactant is used to disperse it in water in the monomer for forming an insoluble acrylic resin in the reaction vessel. A small amount was added, and the composition for acrylic emulsion formation containing a polymerization initiator and a solvent was supplied, and polymerization reaction was performed. The content of the dispersant is preferably 0.1 to 0.5 wt% based on the total weight of the acrylic emulsion-forming composition. If the content of the dispersant is more than 5w%, the particle reduction effect is insignificant, and less than 0.1 wt%. Note that the particle size will be rather larger. The polymerization initiator is a substance that plays a role of initiating the polymerization reaction of the acrylic emulsion-forming composition. The content of the polymerization initiator is 0.001 to 0.5 wt% based on the total weight of the acrylic emulsion-forming composition. In terms of reactivity of the reaction has resulted in undesirable results.

A viscosity modifier and a solvent were applied to change the viscosity or to change the turbidity (color). Viscosity modifiers can be any material that can contribute to the viscosity control generally used. Acrylic emulsion resin prepared by the above method was stable alkaline (pH 8.0 ~ 9.0) was able to form a room temperature film.

As shown in the above results, the prepared organic solvent for paint has almost no formaldehyde emission amount, and since volatile organic compounds and eight harmful substances are not all detected within the allowable range, it can be seen that the solvent can be used as an environmentally friendly paint solvent.

Secondly, when the interaction with the paint solvent due to the introduction of ocher and elvan is explained, it is easy to purchase as a solid in the acrylic emulsion resin prepared by the above method, it is inexpensive, there is no harmful substance and no toxicity, and shows various functions. Ocher and elvan were added as the main solids. In addition to the main solids, TiO2 powder, talc and calcium carbonate were added.

1) Paint with ocher as main solid

In the case of paints based on ocher, they were used as main solids for indoor eco-friendly paints by utilizing the characteristics of ocher, highlighting the color and the advantage of being easily available locally. First, ocher was added to the prepared paint solvent, and the change in the viscosity of the paint according to the added amount was examined. In addition, the microstructure of the used ocher powder was examined through an electron microscope. The change of the weight of the ocher powder added to the solvent 250 cc was observed. In the case of the ocher powder, a very fine powder size of 2 μm-10 μm was observed, and the viscosity increased with the addition of the solvent. Since about 1500 cps as a viscosity of a general indoor paint shows a good result in terms of workability, the content of ocher was adjusted to adjust the final viscosity of the paint of the present invention to 1500-1600 cps. In this study, 120 g of loess was added based on the amount of solvent 250 cc, since the viscosity increase due to the addition of auxiliary materials (TiO2 powder, talc and calcium carbonate) added in addition to loess should be considered.

2) Paint based on elvan

In the case of paints based on ocher, the color of ocher appears in terms of color, and it is difficult to express various colors according to the needs of consumers. The paint was prepared. As in the case of loess, the experiment was performed by varying the amount of elvan in the solvent. The change in the viscosity of the paint according to the addition of the elvan powder, that is, the change in the weight of the ocher powder added to the solvent 250 cc, showed a powder size of 5 μm to 20 μm in the case of the elvan powder. The viscosity increased accordingly. Compared with the addition of yellow soil, the increase in viscosity was not large, and thus a relatively large amount of solids was added. In order to achieve a final viscosity of about 1500 cps, 150 g of ganbanite was added based on the amount of solvent 250 cc.

Third, improve the physical properties by adding TiO2 or auxiliary materials

The properties and advantages of the paint obtained by the addition of auxiliary materials including TiO2 are as follows. Adjusting the workability according to the increase in viscosity, the cost of the product is reduced due to the relatively low price, all white powder has the advantage of increasing the whiteness of the paint, the concealment rate by the reflection of light. For this reason, addition of auxiliary materials is essential, and as the addition of these auxiliary materials increases the viscosity of the paint, the color also changes to a color close to white. However, the addition of ocher did not significantly deviate from the original color of the ocher, and the addition of elvan showed the change of color from gray to pale gray close to white.

Fourth, the removal of the smell of paint using a fragrance.

In the case of the paint produced by the above method, there is no release of harmful components to the human body, but it exhibits a slight smell of ammonia system, and thus the removal of the smell is required for indoor use. In order to remove the odor, an industrial flavor (for water paint) was used to add the paint within a range that does not affect the physical properties of the paint. When the pine flavored industrial flavor was added, a minimum amount of ammonia-free ammonia was selected in consideration of the price of the industrial flavor and applied to the paint within the range of 0.5-1.0 vol%. As shown in the results after application, the ammonia odor was completely eliminated and a light odor of odor which was almost odorless was expressed.

Fifth, control of paint properties according to the mixing ratio of all solid components and solvents.

In the present invention, the addition ratio of the solvent and the solid content was determined according to the addition ratio such that the viscosity of the paint is 1500-1600 cps, and the mixing ratio of the loess and the auxiliary material, the elvan and the auxiliary material was about 70: 30 by weight ratio. Was maintained. In the case of auxiliary materials, the mixing ratio of TiO 2, talc, and calcium carbonate was added in a ratio of 100: 50: 50 by weight, respectively. Eco-friendly paint composition prepared by the above mixing ratio satisfied all the basic conditions that the paint should have.

Referring to FIG. 1, a process of manufacturing furniture using an eco-friendly paint composition as described above is described below. First, the surface of the furniture is polished (S1), and 80 wt% of the eco-friendly paint composition and 20 wt% of silver nano are mixed. Step (S2) of applying paint to the surface of the furniture, step (S3) of drying in natural state for 2 to 3 hours, step (S4) of regrinding the surface of the furniture with sanding paper after drying, and Step (S5) to draw a painting on the surface of the furniture with a pattern roller, and drying the painting (S6), and coating the surface of the painting with a mixture of 80wt% of the eco-friendly paint composition and 20wt% of silver nano It consists of a step (S7) and the step of drying it (S8).

In addition, the content of the paint in the step S7 is 70wt% of the environmentally friendly paint composition and 30wt% of water is included in the concept of the present invention.

In the step S6 of drawing the intermediate picture, the intermediate picture draws a picture of various patterns by mixing a colorant in the eco-friendly paint composition.

By preparing a paint by mixing silver nano with an eco-friendly paint composition as described above, silver has a bactericidal function in silver nano, while general antibiotics scatter five to six pathogens, while colloidal silver has no toxicity to the human body, 650 Sterilize several pathogens.

Sterilization of bacteria, bacteria, viruses, and fungi within 6 minutes (2 ppm standard) does not cause side effects or resistance, purifies the blood, promotes blood circulation and enhances immunity.

In addition, colloidal silver (anion) has a function of controlling the balance of the human body by stabilizing autonomic nerves. Negative ions should use 99.99% or more pure silver and dilute to 10-20%.

Anion generated in the furniture produced by the method as described above was found to occur 500 ~ 1000EA / cc.
