Description

Coating composition for coatings using natural materials {ADHESIVE COMPOSITION FOR PAINT UTILIZING NATURAL MATERIAL}

The present invention relates to a coating agent composition that can be used as a paint substitute for buildings that can release the fragrance and anion of green plants while suppressing the use of substances harmful to the human body by excluding only organic compounds and using only natural materials.

Since most of the adhesives and coating agents currently on the market are composed of organic compounds, especially synthetic resins, volatile organic compounds such as toluene, benzene, and xylene for a certain period of time in daily living products such as homes, automobiles, furniture, etc. Environmental pollutants such as VOCs and formaldehyde (HCHO) are generated and cause atopic dermatitis and bronchitis.

In order to avoid such a problem, an air purifier or the like will be installed. However, this problem cannot be recognized as a satisfactory solution because it is fundamentally unable to solve the problem, and still remains an economically and environmentally concomitant problem.

In order to avoid the above problems, the adhesive used for paper, etc., may be used to make flour paste as before, but it is easy to rot and deteriorates adhesive strength. Furthermore, glues made of animal bone and / or skin are conventionally used. Has been widely used as an adhesive for furniture using wood, but it is not economical because it takes time to prepare because it is put together with water in a certain container and heated, and it can be used after a certain time because it solidifies with time. Since there is a problem that is missing, these days it is only used by some craftsmen in the manufacture of high prices or dining table.

As a solution to this problem, dopants, architectural finishes, and exterior materials containing or adhering silver particles (nano silver) or silver yarn have been introduced, but such nano silver has excellent antibacterial properties, but volatile organic compounds (VOCs) in the air ), It is difficult to remove environmental pollutants such as formaldehyde (HCHO), furthermore, the price of nano silver is expensive, and there is a problem that the antimicrobial activity is degraded due to immersion by the adhesive or the like to the substrate to be used, Its use is limited and not suitable for the removal of the substance.

Conventionally, zeolites have been widely used for the purpose of water purification, radioactive waste treatment, cleaning, drying, and thermal insulation, and have been attempted to apply them to indoor hazardous substances removal, but zeolites can remove some harmful substances due to their adsorption capacity. Laboratory direct contact of volatile organic materials can significantly recognize their removal ability. However, since volatile organic substances are not moved to and treated by zeolite in a residential environment or the like, the zeolite alone cannot substantially remove the desired organic compound even to substances in which these harmful substances do not directly contact the zeolite.

In order to solve the above problems, it has recently been proposed to use anion and / or far infrared ray generating material (Utility Model Registration No. 20-328609, Published Patent Publication No. 10-2004-34625, Japanese Patent Application No. 2003-78841, etc.). For example, the patent application for the use of minerals such as tourmaline, precious stones, ganban stones, uwangwang, ghost stones, quartz, and monzonite is not yet known for various activities and uses of the minerals themselves. In many cases, the inventors arbitrarily use or judge and file a patent. Moreover, the problem of these inventions is that most of them use petroleum resins, which are aromatic organic compounds, as adhesive components. Inhibiting the generation of pollutants is unsatisfactory and mostly untested.

The recent intention to use natural materials such as plants and seafoods without using such organic compounds is shown in recent patent publications. That is, Patent No. 10-0202789 discloses a coating agent containing a natural pulverized product and / or a cellulose sponge pulverized product, which is a natural adhesive such as glue, albumin casein, starch, wheat protein (grass). After coating using the present invention, a method of adhering chaff and sawdust powder thereon is disclosed. In other words, the patent is to apply a natural adhesive to the surface of the base material, and then to adhere the natural pulverized product or cellulose sponge to the surface of the house or furniture to suppress the generation of volatile organic compounds.

However, the present invention is not a substitute for the adhesive of the organic compound used under the surface of a building or furniture, so it is not possible to completely suppress harmful substances generated from the organic compound under the surface, and cracks on the surface over time. When it is generated or peeled off, the remaining volatile organic compounds are discharged again, and thus cannot be completely suppressed.

In addition, conventional adhesives or coating agents called natural adhesives have been introduced to have so-called useful functions by anions or infrared emitting materials, but in practice, most of the functional materials are externally dried when the functional materials are mixed with the adhesive. In fact, since it is blocked from air, the action by the functional substance is extremely minimal.

Accordingly, the present inventors found that the glue was dissolved in an aqueous solution of sodium chloride or calcium chloride at room temperature or low temperature, and found to remain in a sol state and not to solidify over time. No. 0553475, the natural coating agent using the glue according to the invention was excellent in adhesiveness, there was no denaturation, color change, peeling phenomenon, etc. over time, the present invention by further improving the natural coating agent having such characteristics It was completed.

Another aspect of the invention is characterized in that ocher is added in place of the white clay.

Hereinafter, the present invention will be described in more detail, and the description will be made of a natural binder which is a basic element of the coating agent composition for coating of the present invention.

The natural binder according to the present invention is a coating agent composition obtained by mixing and stirring glue in an aqueous solution of sodium chloride or calcium chloride, and the natural binder may further contain some natural materials as described below in addition to the above elements.

Glue is dissolved in an aqueous solution of sodium chloride or calcium chloride, and is maintained in a liquid sol state at room temperature even without heating. The aqueous solution of sodium chloride or calcium chloride is a general aqueous solution used in physiological saline, Ringer's solution, etc. For example, physiological saline is sterile saline containing 0.9 g of sodium chloride in 100 ml of distilled water, and 0.03% of potassium chloride and 0.033% of calcium chloride are added to Ringer's solution. Such an aqueous solution of sodium chloride or calcium chloride keeps the glue in a sol state and is excellent in mixing with other materials.

Blending the glue to an aqueous solution of sodium chloride or calcium chloride is accomplished by mixing the aqueous solution of glue and sodium chloride or calcium chloride at a ratio of about 1: 6 to 1:10 (weight ratio) and stirring it at about 100 to 500 rpm for about 30 minutes to 2 hours. Obtained.

Long-term storage of the composition of the glue and aqueous solution of sodium chloride or calcium chloride as it is deteriorated or decayed in order to prevent this, so that the antimicrobial and antiseptic protein of 3.5 to 7.0 and / or pH 4 to 5 떫 reduction solution (枾 漆 液) Each of about 0.1 to 3.0 parts by weight of a homomixer can be obtained by stirring at about 7000 to 8000 rpm to obtain a long-term storage coating agent, the natural binder of the present invention comprises a composition containing a combination of cypress essential oil and / or steamed sap.

In addition, the natural binder of the present invention may be a mixture of about 8 to 30 parts by weight of seaweed powder, such as invisible starfish, radish, seaweed, seaweed, etc., to the coating agent in which the glue is added to an aqueous solution of sodium chloride or calcium chloride. Since the adhesive strength is increased, it can be usefully used for the adhesion of materials such as wood, paper, leather.

Moreover, the natural binder of this invention contains the thing which mix | blended natural calcium carbonate, especially lime powder, shell powder with the coating agent which mix | blended glue with sodium chloride or the calcium chloride aqueous solution in 0.1-30 weight ratio.

Coatings containing these components enhance the strength and are also useful for smoothing the surface for use on uneven surfaces to maintain solid content. At this time, the stirring is uniformly mixed in about 30 minutes at about 100-500 rpm.

In addition, the natural binder of the present invention, after adding 35-85 parts by weight of lacquer sap to the aqueous solution composition of the above-mentioned glue and sodium chloride or calcium chloride for use as a coating material or coating agent for metal, wood, paper, etc. 20-45 weight part of oil is added, and the thing obtained by stirring for about 30 minutes at 100-500 rpm is included.

As described above, the natural binder constituting the coating agent for the paint of the present invention is environmentally friendly because natural materials are used without using the synthesized compound, especially an organic compound, and there is no fear of generating such environmental pollutants.

Hereinafter will be described in more detail with respect to the coating composition for a coating of the present invention comprising a natural binder as described above.

Example 1

35 wt% of the natural binder was mixed with 35 wt% of ocher and 30 wt% of water, or 30 wt% of ocher for lighter colors, and 5 wt% of titanium dioxide dispersion solution was mixed to prepare a coating agent for an aqueous paint. .

As a result, the color is dark ocher, which gives a monotonous and dark feeling as a single color, which is not suitable as an interior coating agent.

Example 2

30% by weight of water, 35% by weight of mugwort powder, 1% by weight of green tea powder, 1% by weight of pine needle powder, 5% by weight of wood flour, 3% by weight of tourmaline and powderless ( The white stone powder is used as a main component of silica) to prepare a coating material for the constituent paint by mixing 24% by weight, wherein the color is light green in natural color, and 1 to 4% by weight of ocher is included in the range. The results of color observation by adjusting the weight ratio under the condition of reducing powderless when added by weight percent also showed a suitable color by using paint coating agent such as gradually getting ivory color. There is a problem such as forming or color change, which is not suitable for practical use for paint.

Example 3

The inventors have determined that the cause of the color change or spot in Example 2 is due to the influence of the raw material (material), and to find each of the materials in the combination as shown in Table 1 below to find the cause of the color change or spot. After 1 day of mixing and applying, it was examined whether color spots or spots were formed.

TABLE 1

Material Sample 1 Sample 2 Sample 3 Sample 4 Sample 5 Sample 6 Sample 7 Sample 8 Sample 9 Sample 10 Natural Binder 35 66.7 66 66 62.5 57.3 49.4 38.5 35 35 water 17.5 33.3 33 32.5 31.2 28.5 24.7 19.2 17.5 17.5 Wormwood Powder 0.5 One One 0.9 0.8 0.7 0.5 0.5 0.5 Green tea powder One 0.5 1.8 1.6 1.4 1.1 One One Pine needle powder 2 3.6 3.8 2.8 2.2 2 2 Wood powder 5 8 7 5.5 5 5 Tourmaline 10 14 11 10 10 Powderless 20 22 20 ocher 9 9 9 White clay 20 Color change / spot after 1 day Spot color Good Good Good Good Good spot spot Spot color Good

As shown in the results of Table 1, spots appeared when torumarin (sample 7) or torumarin and powderless (sample 8) were mixed, and in the case of powderless, hiding power, that is, mixing property, when mixed with other materials. While it could be observed that it was not good, the result of mixing the white clay with the powderlessness showed not only good condition without spots and color change, but also mixed with torumarin (sample 10). The characteristic suitable for the use of paint was shown.

Example 4

Based on the results of Example 3, first, in order to obtain a light-colored paint that can be applied to various building materials, 30% by weight of water, wood powder, and 35% by weight of a natural binder made of a mixture of an aqueous solution of sodium chloride or calcium chloride 5 wt% of each was mixed and stirred, and 30 wt% of white clay was added and dispersed to examine whether color change or spots occurred, drying time after application, and peeling phenomenon of the coating agent after drying for 7 days.

As a result, the paint was completely dried within 3 hours after the coating was applied to maintain the strength such that it was not scratched even if rubbed or scratched by hand. After 7 days, peeling, color change and spots did not appear. Natural color is preserved as it is, and it shows a suitable state as a paint.In this case, 34 ~ 36% by weight of natural binder, 28 ~ 30% by weight of water, 4 ~ 6% by weight of wood powder in consideration of workability, mixing and good quality control %, White clay can be adjusted in the range of 28 to 30% by weight.

Here, in the case of wood flour, there is no particular limitation, but considering the concealability and mixing properties after drying the paint, preferably 100 mesh or less.

When wood powder is mixed with the paint coating agent, the wood powder forms fine pores in the paint coating layer to improve air permeability and hygroscopicity, and it is completely dried after 2 to 3 periods after application. The drying speed is very fast, and the improvement of air permeability and hygroscopicity due to the fine pores absorbs moisture in the air and when combined with other functional materials, such as tourmaline or natural flavor plants, as described below, There is an advantage of increasing the anion divergence and the fragrance divergence of the natural fragrance generating material.

Example 5

Paint obtained by adding one or two or more natural plant leaf powders such as mugwort powder, green tea powder, pine needle powder, etc., to prepare a paint coating agent having a light green color, based on the paint coating composition according to the result of Example 4 After the coating agent was prepared, it was applied to confirm the peeling, the color change, the presence of spots, etc., all showed a good state.

At this time, 0.5% by weight of one or two or more mixtures of mugwort powder, green tea powder and pine needle powder in a range of 1.0 to 3.5% by weight relative to 35% by weight binder, 30% by weight water, 5% by weight wood powder and 30% by weight white clay. It is preferable to add more and, accordingly, to reduce the weight ratio of water and to adjust it, and when natural plant leaf powder is mixed with 3.5% by weight or more, the green-based color becomes dark and not natural, and natural plant leaf powder is more than necessary. It was not desirable to be exposed to and hurt the aesthetic.

As described above, the coating agent mixed with the wood powder and the plant leaf powder has excellent air permeability and hygroscopicity due to the pores, that is, when such coating agent is applied to the interior wall of the building, the coating agent is damp when the humidity in the room is high. It absorbs and stores it and discharges it when the humidity in the air is low, so it is possible to control the indoor humidity, and furthermore, the moisture absorbed by the coating agent is discharged after contact with the plant leaf powder, thus emitting more natural flavor of plant leaf. You can do it.

Example 6

Based on the paint coating composition according to the result of Example 5, the addition of tourmaline, which is a tourmaline was possible to prepare a coating coating to generate anion, when mixing with white clay as in Example 3 Since spots caused by tourmaline do not occur, preferably, 35% by weight of binder, 30% by weight of water, 5% by weight of wood powder, 28% by weight of white clay and one or two or more mixtures of mugwort powder, green tea powder and pine needle powder 8% by weight of tourmaline is added to 2% by weight, and each weight ratio of water and white clay is reduced and adjusted by the weight% of tourmaline added, thereby preventing peeling, color change and spots. The coating agent for was obtained.

As described above, the coating agent for paints improves air permeability by wood powder, thereby increasing the divergence of the natural aroma and further increasing the divergence of the anion released from the tourmaline to double the functional action.

Example 7

Based on the paint coating composition according to the results of Examples 4 to 6, ocher was added to prepare a paint coating material having an ivory color control, wherein 0.5 for each mixture of Examples 4 to 6 When ˜5% by weight was further added, and thus the weight ratio of the white clay was reduced and adjusted, practical ivory color appeared, and in this case, no peeling, color change, spots, and the like appeared.

Of course, when the paint coating agent of the present invention is used as a paint of the building, such as loess soil, it is possible to replace the white clay added in Example 4 as shown in Example 8 below.

Example 8

Water and wood powder are mixed and stirred in a natural binder obtained by mixing glue with an aqueous solution of sodium chloride or calcium chloride, and then yellow clay coating agent can be obtained by adding and dispersing ocher. Thus, the binder is 35% by weight and 30% by weight of water. %, Wood powder 5% by weight, was applied to the coating agent for 30% by weight of ocher, the result of checking the abnormality of peeling, color change, spots, it was possible to manufacture a practical coating material.

At this time, the blending ratio of the material was adjustable in the range of 34 to 36% by weight binder, 28 to 30% by weight water, 4 to 6% by weight wood powder, 28 to 30% by weight ocher.

As can be seen from the above description, according to the coating agent using the natural material of the present invention, since only the natural material is used above all, no harmful substances are generated, and the strength is excellent and the coating agent for colored to white paint can be obtained. Therefore, it can be used as a coating material for various building materials or wallpaper, there is an advantage that it is versatile as a paint coating agent.

In addition, when the natural plant leaf powder is added, the color of light green is controlled as well as the color of ivory is adjusted according to the combination of ocher, such as free color control suitable as a coating material for building materials according to the appropriate blending ratio of natural materials. There is an advantage that can be appropriately adapted to the building material of various uses.

In addition, the pores formed by the wood powder shorten the drying time of the paint, improves breathability and hygroscopicity, and thus can control the humidity in the room, and furthermore, when it is combined with a functional material such as plant leaf powder, tourmaline or ocher, It has the effect of doubling its inherent function by increasing the generation of negative ions and the divergence of the odor generated by natural plants.

Since the coating agent for the paint of the present invention can be applied directly on the old wallpaper as a substitute for the wallpaper or by a strong adhesive force, it eliminates troublesome tasks such as removing the wallpaper, applying an adhesive paste to the wall, and attaching the wallpaper. It has an advantageous effect that can be easily decorated.
