Description

Powder for environment-friendly paint {Powerder for nature-friendly paint}

The present invention relates to a powder for eco-friendly paints, and more particularly to a powder for eco-friendly paints having environmental characteristics and ease of use.

In recent years, environmental friendliness has been taken into consideration for the improvement of living standards and for the environment and health. Especially in the case of conventional synthetic resin emulsion paints, known as the so-called sick house syndrome, it is known that volatile organic compounds harmful to the human body are emitted in a small amount, and it is known that they reside after a certain period of time.

Many of the technologies of eco-friendly paints have been proposed according to the needs as described above. For example, in the registered patent No. 931381, a first composition is prepared by mixing an alfalfa cactus powder, a germanium powder, and titanium dioxide (TiO 2) in a weight ratio of 10:40:10 to 20:50 to 70 to prepare a first composition, To 100% by weight of water and 1 to 3% by weight of a curing accelerator, 16 to 22% by weight of methanol or ethanol and 63 to 70% by weight of water to prepare a second composition, And the second composition is prepared by mixing at a weight ratio of 25 to 40: 60 to 75.

In addition, Japanese Patent Laid-Open No. 2009-0003901 discloses an environmentally-friendly functional pattern capable of forming negative patterns, antimicrobial and deodorizing functions, and easily hand-painted using a paint brush without paint facilities and thus forming patterns similar to the texture of wood The present invention relates to a coating composition, and more particularly to a coating composition which comprises 0.1 to 0.5% by weight of a dispersing agent, 25 to 35% by weight of water, 20 to 45% by weight of any one of organic binder selected from acrylic emulsion resin, water-dispersible polyurethane resin, By weight of antimicrobial agent, 0.2 to 1% by weight of preservative, 0.1 to 1% by weight of defoamer and 0.1 to 1% by weight of antifoaming agent, 1 to 5% by weight of a water-soluble organic solvent is mixed and dispersed in a blender at a RPM of 1000 to 2000 for about 30 minutes to prepare an eco-friendly functional pattern coating composition.

Japanese Patent No. 853475 discloses an acrylic resin emulsion containing 30 to 40 wt% of an acrylic resin emulsion, 1 to 15 wt% of titanium dioxide, 20 to 30 wt% of anion ceramics, 1 to 20 wt% of anilite, 1 to 3 wt% 1 to 2% by weight of an anti-settling agent, and water as the remainder.

On the other hand, loess is a typical eco-friendly material, and many coatings containing the loess component have been proposed. However, due to the particle size of the loess itself, cracking, adhesiveness, and curability even if some natural ingredients are added. For example, epoxies and EG (ethylene glycol), which are applied to improve the adhesiveness and the finishability, are harmful to the human body due to the chemicals of additives such as resins and additives. These substances cause beneficial components of natural materials such as loess And the effect of health promotion is reduced by half.

In addition, most of the water-based paints in building finishes are liquid, and 1G and 18L can not be used because they are not widely available.

 Some remedies have been proposed to overcome these problems, including cracking, adhesion, and adhesion. In particular, when resins and additives used for natural materials such as clay loose materials include some toxic and organic solvents such as formaldehyde, conventional synthetic resin coatings And there was no difference between them.

The present invention has been made in order to overcome the disadvantages of the prior art, and it is an object of the present invention to provide an eco-friendly paint powder which is excellent in environmental characteristics and can be conveniently used.

In order to attain the above object, the present invention provides an eco-friendly paint powder which is prepared by mixing water and used as a paint, wherein 100 parts by weight of a main powder exhibiting environmentally friendly characteristics, 15 parts by weight to 100 parts by weight of a water- To 1.0 part by weight, from 0.1 to 1.0 part by weight of the thickener powder, and from 0.2 to 1.0 part by weight of the additive powder.

Preferably, the main powder is at least one selected from the group consisting of clay, clay, volcanic acid, diatomaceous earth, coal charcoal powder, ilite, germanium, quartz, vermiculite, mica, talc, feldspar, silica and jade.
