Description

Plasterer Finishing Material for Buildings {New Finishing Material with the Inner Wall Surface}

An object of the present invention relates to a new plaster finish that has excellent performance, such as humidity control, adsorption, heat insulation, flame retardancy, etc. consisting of a volcanic cladding material as a main raw material for plastering plastering the interior walls of buildings, etc. Therefore, the intrinsic characteristics of the volcanic debris will be supplemented and improved to provide a plastering finish of the inner wall of the building with added adhesion to the inner wall of the building.

The present invention is a complex porous structure and composed of silicon oxide and aluminum oxide as the main components, using the volcanic chain snow with excellent moisture control (humidity), gas adsorption, organic material absorption, heat insulation, etc. It's about a new plasterer.

As is well known, volcanic debris is a so-called volcanic ash that is a deposit of volcanic debris resulting from the massive eruption of a volcano about 25,000 years ago. This sediment is very excellent in water control function, odor adsorption, removal of repellent chemicals such as formaldehyde, anion generation, heat insulation, etc. due to the intrinsic properties of volcanic chain sulfide called porosity. Therefore, studies on the utilization of volcanic debris have been carried out incessantly, and as a result, many achievements have been disclosed as patents and practical applications. In other words, the volcanic cladding has been manufactured and used as roadbed components, road pavement, wall and floor plastering, tiles, and blocks.

However, they are consistently weak in strength and adhesion in the standard state (25 ° C, 1 atm), and thus have been difficult to handle easily during construction. In addition, this volcanic clam sulphate is not processed at particle size, absorption rate and density, but is used directly at the construction site.In general, the particles are not uniform and fine in general, and the high water content is very difficult to handle with water. This is a very difficult to handle, and it is necessary to take additional measures to compensate for it. Therefore, complaints have become an important quality improvement initiative.

Therefore, many researchers have made efforts to overcome and solve these problems. The representative example is the zero slump press molding method developed by Japan's Sankai, Inc. Volcanic debris is not concreted by known conventional methods. This is because moisture control is very difficult due to the porosity of volcanic cladding. On the other hand, when the volcanic clathrate is treated at high temperature (1100 ℃), silicic acid, which is the main component of volcanic clathrate, is swollen like a ball. By using this change, it is used as an abrasive, porous special glass, interior finishing material, etc. It was used as a heat insulating paint, heat insulating mortar, and lightweight concrete. In addition, many researches have been conducted on the interior walls of buildings, especially in Kagoshima, Japan, to develop interior and exterior wall finishing materials using volcanic debris, gypsum, hemp and natural binders. I've done it.

However, in each of these cases, one thing in common is found. In other words, as a finishing material for the wall or in particular the ceiling is a phenomenon that easily falls after finishing the plastering, the fact that the fastening power is very lacking. An alternative to this is to add additional plaster and then treat it. After plastering, bed crystals have to take place and take at least two hours. In addition, using water-soluble polysaccharides such as pectin, etc., relatively good results were obtained in the construction to the ceiling. However, it is not very suitable as a fixing agent, because it is not effective in terms of function and economics.

Korean Patent 'Architectural Coating Material, Building Finishing Panel and Manufacturing Method' (Registration No. 10-0779863, Nov. 21, 2007) shows that spring, clay, cement, gypsum, calcined lime and synthetic resin It is used without precise concentration display, and water-soluble cellulose ether, water-soluble methyl cellulose, hydroxymethyl cellulose and the like are used as an adhesive reinforcing material without accurate concentration display. In addition, the use of volcanic siliceous is 50 to 65% and the binder is also 40 to 50% (20 to 32.5% in total concentration) compared to the volcanic siliceous, which is difficult to see in practical and accurate results. And the adhesion enhancer is also 0.08 to 2%, so the concentration range is not precise.

In addition, the Korean Patent 'Paint Composition' (Registration No. 10-0691068, 2007. 02. 27) also has a wide application range of 30 to 40% by weight of acetic acid-based inorganic powder resin as a coating material, and also a silicone acrylic emulsion as a water-soluble top coating material 20 to The application range is 30% by weight, which is very wide. As a similar case, the Korean patent 'Inorganic coating material composition having moisture control' (Registration No. 10-0651080, Nov. 22, 2006) also includes a resin binder (ethylene vinyl acetate copolymer, styrene acryl) based on 100 parts by weight of a humidity agent such as silica gel. 10 to 45 parts by weight of a latex copolymer or polyvinyl alcohol), and its application is also wide. Inorganic binders (limestone or calcium silicate) are also 70 to 200 parts by weight relative to 100 parts by weight of the humectant, a very wide range of application.

In addition, Korean patent 'Wall coating composition using natural protein-based resin' (Registration No. 10-0635334, Oct. 11, 2006) shows that the use of various porous mineral materials such as volcanic chain sills is 5 to 30% by weight. It is a big figure. In addition, the amount of protein fiber resin is also 10 to 30% by weight, the concentration range is not precise. Also disclosed in Korean Patent Publication No. 10-2005-0071461 for finishing the wall coating material composition using pojoran and its manufacturing method (published No. 10-2005-0071461) of the polyacrylic emulsion resin or polyethylenevinylacetate emulsion resin to 5.0 to 35% by weight It is judged that the application range is very wide by using it as a negative.

Therefore, it has been called for the development of interior wall plaster finishes that utilize more volcanic debris, which is more effective and very beautiful by having a very precise application range.

The present invention is to provide a new building interior wall plastering finishing material to increase the fixing ability of the interior wall plastering finishing material and at the same time improve the effectiveness and economics. In other words, it is not harmful to the human body in order to increase the fixing ability of plastering finishing materials on building walls, it shows smooth fixing action, and has excellent fixing ability including fastening agent made of a compound composed of nature-friendly materials, and the use amount is very precise. To provide a wall plaster finish.

Building wall finishes manufactured using volcanic debris, despite the advantages of excellent thermal insulation, good warmth, exquisite humidity control, excellent odor removal ability, good adsorption to toxic substances, and excellent negligible flame retardancy, When it is applied to the interior wall finishing, the problem of fixation has always been raised due to the disturbing nature, which is a unique characteristic of volcanic debris. In this way, the problem of fixing the volcanic cladding ability is improved by adding a nature-friendly element to increase the fixing power so that the characteristics of the excellent volcanic cladding can be expressed without damage, thereby converting it into a very good plaster finish in an environmentally friendly building. Plasterer wants to provide.

I became holy.

And here, the concentration (weight%) range of each composition is not relatively the same as the composition concentration range discussed in other documents, patents, etc., because it is relatively easy to obtain very good results when maintaining this concentration range.

Looking at the composition of these compositions in detail,
