Internal plastering materials of strcuture for air purifying

The present invention relates to an interior plaster finish composition of a building that provides an environmentally friendly air quality improvement effect, and more specifically, by selecting and using kaolin by various particle sizes. Kaolins of size play a role of gravel, kale of small particle sizes play a role of sand, and EVA resin, an acetic acid resin, plays a role of cement admixture, which is used by bubbles generated during water repellent of acetic acid resin. The present invention relates to a finishing composition for the interior of the building to increase the binding strength of the material.

Sick House Syndrome is a term used to refer to the health problems and discomforts of residents due to harmful substances from building materials and wallpaper used to rebuild buildings. Benzene, toluene and chloro There are volatile organic compounds called VOCs (Volatile Organic Compounds) such as foam, acetone, styrene, formaldehyde, and the like, which contain carcinogens.

In addition, there may be contaminants such as radon, asbestos, carbon monoxide, carbon dioxide, nitrogen oxides, ozone, fine dust, and airborne bacteria that occur when building a house.In addition, organisms such as fungi and viruses such as bacteria, ticks, etc. Pollution is a factor, but when these pollutants are not discharged out of the building and accumulate indoors, they cause various problems.

Recently, as the perception of the residential environment has changed and well-being has been pursued, research on the management of indoor air quality and research on harmful and pollutants has been actively conducted. Various methods have been proposed to not only remove the VOCs by manufacturing or coating the surface, but also to secure deodorizing and antibacterial properties.

In Korean Patent Publication No. 2005-0093048, a natural aluminum silicate composition is made by mixing ocher, illite, zeolite and diatomaceous earth at 1: 1: 1: 1, and another composition is 60% to 90% natural stone. 20% to 5%, 10% to 1% anion stone, 5% to 10% charcoal, 0.1% to 5% titanium dioxide (TiO ₂ ) is added, and the functional mixture and the natural aluminum silicate composition are added again 1: 1 to 2: A plaster finish composition is proposed to improve the indoor air quality used in combination.

In addition, the Republic of Korea Patent Publication No. 2006-0059110 technology is a means for providing a building finishing material having a natural mineral powder ceramic as the main raw material to reduce the heating and cooling costs, fine dust, cement toxicity and neutralization of the binder, feldspar And mica (Ilite) are polymerized into 325 ~ 400 mesh, and antibacterial, deodorant, and fungicide are mixed well with liquid binder including water-soluble emulsion with powder ceramic and liquid natural fragrance. It is mentioned that construction can supply fresh air to provide a comfortable indoor environment.

However, even if the ideal finish composition is proposed, the use of high-quality materials, as described above, can not be practically supplied at a suitable product price that can be purchased by construction companies or users, and thus has problems in adaptation. In the area of providing air quality improvement effect, there are still insufficient problems.

Therefore, the present inventors can use the nature-friendly raw materials when provided with the interior finishing finish composition composition provided in the present application can be purchased casually by the consumer, it is a relatively low-cost product and durable and provide an air quality improvement effect for a long time It confirmed the effect and came to complete this invention.

Our company uses kaolin and ground algae (white) and plastic shell powder as natural materials, and applies kaolin to different particle sizes according to the purpose of use.
