In particular, the conventional water-based paints applied to the building is a mixture of inorganic fillers such as talc and calcium carbonate and general pigments in acrylic emulsion resin, and its purpose of use is simply the plastering effect of the building. In addition, in the case of the interior water-based paints to give functionality is expensive and is mainly applied only to interior accessories.

The functional water-based paint, for example, using an inorganic raw material of ocher or ceramic system ceramics to release far-infrared rays to activate the energy of the human body, antibacterial paint to inhibit the harmful bacteria, insects, etc. or indoors And paints that emit fragrance for a certain period of time.

In the case of the ceramic paint, since it has been found that natural minerals are generating far-infrared radiation or anion, which is beneficial to the human body, studies on applying natural minerals such as elvanite and biotite to resins have been actively conducted. .

However, these conventional technologies for applying far-infrared radiation materials are limited in scope depending on their characteristics, or when the far-infrared radiation materials or anion materials used have different compositions, and do not suggest a wide range of applications. In particular, in the human body application technology that is closely related to daily life, far-infrared radiation value or negative ion generation value is extremely insignificant, and the effect is not properly exerted, and its use range is extremely limited.

On the other hand, conventional non-polluting paints are known as silicone or acrylic resin paints, fluorine resin paints and emulsion resin paints, wherein the silicone and acrylic resin paints are difficult to cure conditions, the fluororesin paint is a higher alkyl group in the structure Introducing solvent solubility and being low polarized, the contaminants are easily adsorbed onto the coating film, and have a disadvantage in that it is difficult to remove traces of contamination.

Accordingly, the present invention has been proposed to solve the above problems, it is possible to form a thin film coating film of several μm on the surface of the substrate used for general metal products or building materials, excellent adhesion and solvent resistance and high The object of the present invention is to provide an acrylic aqueous coating that can withstand processability and that can emit far infrared radiation and anion effectively.

In order to achieve the above object, the present invention is an acrylic water-based paint obtained by mixing 70-15 wt% of an acrylic resin solution with 2-15 wt% of ceramic powder capable of generating far-infrared rays and anions, and a pigment of 8-15 wt% containing an additive. To provide.

Here, the acrylic resin solution is based on 100 parts by weight of the resin solid content, 10 to 20 parts by weight of butanol for improving the dissolving power and smoothness of the acrylic resin, and 10 to 30 isopropylene alcohol for improving the dissolving power and storage stability of the acrylic resin It is characterized in that it is obtained by adding 20 to 40 parts by weight of toluene for improving the parts by weight and the dryness of the paint and stirring for 15 minutes.

In addition, the ceramic powder is a material generating anion with the far-infrared radiation, for example, tourmaline, loess, chorionic mica, amethyst, raw ore, bamboo charcoal, Uranite, precious stone, obsidian, ganban stone, photonite, lava, ghost stone It is characterized by consisting of one or more charcoal selected from one or more natural stone material or algae, charcoal.

The acrylic paint prepared as described above is applied to various building interior materials, interior accessories, and metal products, thereby maintaining a comfortable indoor environment and exerting a beneficial effect on the human body.

The above objects, features and advantages will become more apparent from the following detailed description.

Hereinafter, the composition of the acrylic aqueous paint releasing far infrared rays and anions according to the present invention will be described in detail.

First, acrylic aqueous paint is obtained by mixing 70-15 wt% of acrylic resin solution with 2-15 wt% of ceramic powder capable of generating far-infrared rays and anions, and 8-15 wt% of pigments containing additives.

Here, the pigment contains an additive of 1 to 3wt% in order to improve the functionality of the ceramic powder, and may further add 1 to 5wt% of a fluorine powder or a water-soluble fluorine compound to increase the non-stick. have.

In the present embodiment, the ceramic powder may be used in combination or in combination with each of the ceramic emitting only an infrared ray and the ceramic emitting anion. In the functional ceramic component of the present embodiment, the far-infrared radiation ceramics and the anion-emitting ceramics are formed in a content ratio of 5 to 15: 1 to 3, wherein the anion-emitting ceramic powder is adjusted in consideration of economic efficiency and efficiency.

More specifically, when the content of the anion-releasing ceramic in the content of the functional ceramic is too high, excess anions are released, and such anions are more likely to contain radioactive elements, which may cause harm to the human body. If it is too low, the amount of negative ions released is insignificant and the negative ions cannot be exerted. In the present invention, the anion content is adjusted to a content of about 600-800 Ion / cc is released in consideration of commercial economics.

On the other hand, the acrylic resin solution was adjusted in consideration of the surface state of the coating film. That is, when the content of the acrylic resin solution is 70wt% or less, the gloss and wear resistance of the coating film may be lowered, and when 90wt% or more, the anionic ceramic particles are buried in the resin solution, and the function thereof is lowered, or the viscosity of the paint is lowered. The flow of the coating may appear.

The present invention as described above is not only possible to emit far-infrared radiation at room temperature, but also capable of firing at a low temperature of about 150 ° C.

In the paint manufacturing process of the present invention, in order to prevent delamination during long-term storage, and in consideration of the physical properties (viscosity, specific gravity, workability) applied to the entire paint, with respect to 100 parts by weight of the acrylic resin solids, The pigment and the solvent are added by a predetermined weight part and stirred to disperse to have a predetermined size μ particle size (25 μ or less in this embodiment).

The pigments may be used pigments and coloring pigments commonly used to represent the color of the paint, in consideration of the desired color, durability and weather resistance, the selected pigment in the range of 10 to 100 is added in the conventional paint manufacturing process It is added in parts by weight.

The solvent includes 10 to 20 parts by weight of butanol for improving the dissolving power and smoothness of the acrylic resin, 10 to 30 parts by weight of isopropylene alcohol for improving the dissolving power and storage stability of the acrylic resin and toluene 20 for improving the dryness of the paint. To 40 parts by weight is added.

The reason why the mixed solvent is used as described above is to improve the physical properties of the paint, and the amount of the mixed solvent is added within the usual range.

At this time, when the addition amount of the butanol is less than 10 parts by weight of the acrylic resin is reduced the solvent solubility decreases the storage stability of the coating, in particular the problem that the smoothness of the surface of the coating film is lowered, if more than 20 parts by weight Drying is delayed in the application process of the prepared paint, and a problem arises that the working environment is poor due to the smell of alcohol.

In addition, when the addition amount in the addition ratio of the isopropyl alcohol is less than 10 parts by weight, the effect is not sufficient, so that the solvent ability of the acrylic resin is lowered, the storage stability of the paint is deteriorated, and if it exceeds 30 parts by weight The problem is that the smoothness of the deterioration occurs.

In addition, when toluene is added in an amount less than 20 parts by weight, there is a problem that the drying is delayed when applying the prepared paint, and when the addition amount is more than 40 parts by weight, the smoothness of the coating film is deteriorated. Done.

On the other hand, in the embodiment of the present invention 1 to 20 parts by weight of an antibacterial ceramic containing titanium oxide and silver, such as titanium oxide and silver for imparting antibacterial and deodorizing function to the acrylic resin solution can be added, these are far infrared rays and anions By acting as a catalyst that can cause synergy of emission, it is possible to maximize far infrared and anion emission function.

As another embodiment for providing the antimicrobial activity, a biocleanact of Micro Science Tech Co., Ltd. may be added as much as 1 to 20 parts by weight based on the acrylic resin solid content, and in this case, the acrylic resin and bioclean 20-50 parts by weight of butyl cellosolve are added together to enhance the compatibility of the acts.

At this time, the bio-clean act is selected in consideration of non-toxic human body, persistence of antimicrobial effect, wide antibacterial range, excellent antimicrobial effect and yellowing resistance, etc., if the added amount is less than 1 part by weight to see sufficient antimicrobial effect If the addition amount exceeds 20 parts by weight, there is a problem that the compatibility with acrylic resin is lowered. In addition, when the amount of the butyl cellussolve is added in an amount less than 20 parts by weight, there is a problem that compatibility between the acrylic resin and the clean act occurs, and when the amount exceeds 50 parts by weight, the application of the prepared paint There is a problem that the drying is delayed in the process.

The paint of the present invention prepared by the above method is applied to the surface of metal or plastic substrates, building materials and the like and is thermally densified to form an inorganic coating film, and can be used with confidence because there is no skin irritation and human toxicity. In addition, it has a strong bactericidal action to inhibit and kill the growth of bacteria such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Salmonella.

Hereinafter, the present invention will be described in more detail with reference to Examples.
