Aqueous paint composition for hand painting {WATER-ACRYLIC PAINTING COMPOSITE FOR HANDPAINTING}

The present invention relates to an aqueous paint composition for hand painting, and more particularly, to a pigment, a water dispersion urethane (Polyurethane dispersion), EVA (Ethylene Vinyl Acetate Copolymer), an acrylic emulsion resin (Pearl), The present invention relates to an aqueous paint composition for hand-painting comprising an emulsion stabilizer (CMC, carboxymethyl cellulose, Carboxymethyl cellulose), a dispersant and calcium carbonate (Calcium Carbonate) at a constant ratio.

Nowadays, we often see products with unique pictures and patterns on clothes (especially jeans, blue jeans, etc.) and bags. When a product is released from a factory, there are no pictures or patterns, but there are a growing number of small shops that buy and sell pictures and patterns. Wearing your own clothes is what sets you apart from others.

As a method of forming such a picture or a pattern on a product, there are various methods, but a hand painting method is usually used.

Korean Patent Application No. 10-2001-0025607 No. 10-2001-0025607 'Three-dimensional pattern forming paper using hand painting technique and three-dimensional pattern forming method using this paper' has been developed as a conventional hand-painting method, but the 'three-dimensional pattern using the hand painting technique' Formation paper and three-dimensional pattern formation method using this paper is a method of forming a pattern on the three-dimensional pattern forming paper by hand-painting method and peeling and attaching the pattern layer by soaking in water to express aesthetic three-dimensional effect and delicate pattern by brush touch. However, when the pattern layer is attached to the product, there is a possibility that cracks may occur in the pattern or pinholes may occur on the oil surface during firing due to the gap between the pattern layer and the product.

In order to overcome this, Korean Patent Application No. 10-2001-0068263 'Hand Painting Ceramic Paints' uses ceramic paints to form a picture or pattern directly with a brush without using a printing method.

However, conventionally, for forming a picture or a three-dimensional pattern, such as cloth, oily paint is used rather than aqueous paint. The reason for not using water-based paints is that the colors penetrate into the interior of the fabric along the texture of the fabric, so that the color of the fabric and the color of the paint are overlapped with each other, and thus there is a problem in forming a desired picture or three-dimensional pattern. On the other hand, oily paints have oily components, so they do not penetrate into the inside of the cloth. Therefore, paintings and three-dimensional patterns are more clearly expressed than aqueous paints. However, oil paints have an oil component, which causes environmental pollution. In addition, there is a problem that requires a high temperature (about 200 degrees) to dry the oil component of oily texture, and there is a problem that there is a legal regulation.

The present invention is to solve the conventional problems as described above, an object of the present invention is to provide an environmentally friendly and water-based paint composition for drying at a low temperature.

It is still another object of the present invention to provide an aqueous paint composition for hand painting in which the texture after painting is soft and the adhesiveness of the paint is maintained during use or washing.

It is still another object of the present invention to provide an aqueous paint composition for hand painting in which the color does not eat on the cloth.

The aqueous paint composition for hand painting according to the present invention comprises a pigment and a resin mixture, wherein the resin mixture is an acrylic emulsion resin (Acryl Emulsion Resin), a water dispersion urethane (Polyurethane dispersion), EVA (Ethylene Vinyl Acetate Copolymer) It provides any one or more of the water-based paint composition for hand painting.

In addition, the present invention, when forming a picture or three-dimensional pattern or the like on the cloth may be further included (Pearl) so that the paint does not penetrate into the inside of the cloth.

On the other hand, the pigment is 12 to 18% by weight, the resin mixture may be 72 to 83% by weight, the pearl (Pearl) may be 5 to 10% by weight.

When the resin mixture includes both the acrylic emulsion resin (Acryl Emulsion Resin), the water dispersion urethane (Polyurethane dispersion), and the EVA (Ethylene Vinyl Acetate Copolymer), the acrylic emulsion resin (Acryl Emulsion Resin) and the water dispersion Urethane (polyurethane dispersion), the weight of the EVA (Ethylene Vinyl Acetate Copolymer) may be 63 to 77% by weight, 8 to 12% by weight, 15 to 25% by weight, respectively.

In addition, the present invention may further include an emulsion stabilizer, a dispersant and calcium carbonate (Calcium Carbonate).

EVA (Ethylene Vinyl Acetate Copolymer) used in the present invention can be used by replacing with a tripolymer (Tripolymer).

In addition, calcium carbonate (Calcium Carbonate) can be used by replacing the clay (Cray).

It will be described in detail with reference to the following examples. However, these examples are for illustrative purposes only and the present invention is not limited thereto.

Example 1 Aqueous Paint Composition for Hand Painting

Aqueous paint composition for hand coating according to an embodiment of the present invention includes a pigment, a resin mixture, Pearl. In addition, the composition may include calcium carbonate or clay, an emulsion stabilizer, a dispersant, and a trace amount of water.

In this case, the resin mixture may use all or selectively an acrylic emulsion resin (Acryl Emulsion Resin), a water dispersion urethane (Polyurethane dispersion) and EVA (Ethylene Vinyl Acetate Copolymer) or a tripolymer (Tripolymer).

At this time, the pigment is 12 to 18% by weight, the resin mixture, 72 to 83% by weight, the pearl (Pearl) comprises 5 to 10% by weight.

On the other hand, 13 ~ 18% by weight of emulsion stabilizer (CMC) of resin mixture, 1 ~ 6% by weight of dispersant and 6 ~ 10% by weight calcium carbonate (Calcium Carbonate) or clay (Cray) of the resin mixture is added It may be included as.

The weight of the resin mixture is both acrylic acrylic resin (Polymer Emulsion Resin) and polyurethane dispersion (Polyurethane dispersion), and either EVA (Ethylene Vinyl Acetate Copolymer) or Tripolymer (weight), respectively, the weight is 63 It is preferred to mix in ~ 77% by weight, 8-12% by weight, 15-25% by weight, but is not limited thereto.

A pigment is a fine particle having a pigment, and is not directly dyed on the surface of the to-be-tainted material, but is attached to the surface of the to-be-tained material by a physical method (adhesion or the like) to give a unique color. In this case, the pigment is used as a meaning including all of the organic pigments, including the dye.

As the pigment, any pigment commonly used in the manufacture of cosmetics, colored pencils, crayons, paints, inks, etc. may be used, but it is effective to select a non-toxic organic pigment, and a commonly used basic pigment may be used.

Polyurethane dispersion utilizes the properties of polyurethane to provide soft and flexible properties to aqueous paint compositions for hand-painting, while preventing cracks in the paint (paint) area. Allow to wash or wash cloth without

Polyurethane materials are being replaced by water-soluble or water-dispersible materials in solvent type, and active research and development around the world. Its uses also include synthetic leather (dry, wet, surface treatment agents, etc.), adhesives (woodwork, panels, shoes, bags, etc.), additives (dispersants, paper sizing agents, textile additives, softeners, etc.), coating agents ( Metals, plastics, etc.), paints (solution paints, etc.), and the like.

EVA (Ethylene Vinyl Acetate Copolymer) is an emulsion resin based on EVA resin, mainly for woodworking (PVC resin-based makeup board), PVC edge and piano back keyboard adhesion, film lamination, wrapping, cement mortar , Wall finishing, ceiling finishing, etc.). In the present invention, EVA (Ethylene Vinyl Acetate Copolymer) or Tripolymer (Tripolymer) is used, so that the aqueous paint composition for hand painting during washing or washing may not fall off from cloth.

Pearl is pearl powder made of pearl or shell of shellfish or scales of fish (such as cutlass). It is mainly used in the field of color cosmetics and widely used in cosmetics such as eye shadow, lipstick, blush, foundation, sunscreen, makeup base, paint, plastic and ceramics. Pearl is made of natural products and artificial ones. The artificial pearls produced these days are physical and chemical properties superior to natural acids, as well as the standardization and uniformity of each particle size. It is spotlighted as a material.

As described above, the biggest reason for not using an aqueous paint to form a picture or a three-dimensional pattern is that the paint penetrates into the fabric. For example, if the fabric is black, even if the worker forms a blue picture or three-dimensional pattern, the blue paint penetrates the black cloth, and the picture or three-dimensional pattern formed by the color of the cloth does not appear well. .

In the aqueous paint composition for handpainting according to the present invention, Pearl was used to prevent this. Pearl is included in the aqueous paint composition for hand painting, thereby preventing the paint from penetrating into the inside of the cloth by the particles of Pearl. In addition, by entering the pearl (Pearl) has the effect that the paint itself has a shiny gloss effect and a three-dimensional feeling. At this time, calcium carbonate (Calcium Carbonate) or clay (Cray) is to help the pearl (Pearl) to function properly.

Emulsifying agents (Emulsifying Agent) is a third substance that makes two kinds of liquids that do not mix with each other into a stable emulsion (emulsion). Among the emulsion stabilizers, CMC (carboxymethyl cellulose) is chemically very stable and is particularly harmless to the human body, and it is used for various purposes such as thickening, emulsion dispersant, adhesive, protective colloid, suspension and so on. CMC is a compound suitable for the general industry, food additives, Korean Pharmacopoeia, additives for fish feed, thickener (jam, ketchup, ramen), water vaporization and anti-aging agent (bread, castella), stabilizer (ice cream, Beer), solids (oils), etc.It is widely used in various fields such as paint (thickening, film formation, dispersion), ceramics or refractory bricks (penetration of glaze, electrodeposition, moisturizing of stability / mortar, initial adhesion) have.

Finally, the dispersant helps to mix the pigment and polyurethane dispersion, EVA (Ethylene Vinyl Acetate Copolymer), Acryl Emulsion Resin (Pearl) and Pearl.

Example 2 Preparation of Aqueous Paint Composition for Hand Painting

In the preparation of the aqueous paint composition for hand painting according to the present invention, a resin mixture obtained by mixing a water dispersion urethane (Polyurethane dispersion) with EVA (Ethylene Vinyl Acetate Copolymer) and Acryl Emulsion Resin (Aryl Emulsion Resin) is used. In addition, in the case of Pearl (Pearl) was used Blue Pearl (Pearl).

First, as a blending step, a resin mixture is prepared by mixing a water-dispersed urethane 10% by weight, 20% by weight EVA and 70% by weight acrylic emulsion resin.

Next, 72 to 83% by weight of the prepared resin mixture, 12 to 18% by weight of pigment, and 5-10% by weight of blue pearl (Pearl) are blended, and an emulsion stabilizer (CMC) of 13 to 18% by weight of the resin mixture is added thereto. A dispersant of 1 to 6% by weight of the resin mixture and calcium carbonate (Calcium Carbonate) of 6 to 10% by weight of the resin mixture are blended. At this time, it is good to mix a small amount of water, the amount of each raw material is added or subtracted according to the weight of the resin mixture.
