Description

Functional paper for wallpaper and its manufacturing method {Fuctional wall paper and its manufacturing method}

In general, the interior walls or floors of residential or office buildings, such as apartments and houses, are finished with cement mortar, and then painted with a medium or wallpaper.

Conventionally, starch-based dopant pools in which chemical adhesives such as formalin, hydrochloric acid, and other chemicals are used as the main components when used on the wall surface are mainly used. The chemical adhesives have strong adhesive strength and can be quickly cured. Most commonly used as starch starch pools.

However, the glueing paste containing the chemical adhesive has a bad effect on the human body, such as dermatitis and respiratory diseases as the harmful ingredients and smells are severely generated in the human body, as well as a lot of time to neutralize the toxicity generated from the adhesive even after the coating. Because of this, there was a limit to creating a pleasant living environment.

In addition, there is a problem that the inhabitants are caused by respiratory diseases and dermatitis due to the toxic continuously generated from the concrete, as well as harmful components and odors generated by the chemical adhesive.

In addition, starch seedling paste is produced in a gel state by kneading starch with water, so when the starch paste is distributed for a long time, the seedling paste is easily decayed, and in winter, mold on the wallpaper due to condensation occurs. In the summer, there was a problem that mold occurs on the wallpaper due to moisture. In order to prevent the occurrence of mold on the wallpaper, antiseptics are added to prevent the occurrence of mold on the wallpaper. There were problems that occurred.

The present invention has been made in order to solve the above problems, excludes the use of chemical adhesives and preservatives that cause harmful components and odors to the human body, and manufactures wallpaper papers using natural materials harmless to the human body Construction prevents the release of harmful substances to the human body, prevents the occurrence of mold on the wallpaper, neutralizes the pollutants generated in concrete, etc. It is an object of the present invention to provide.

In order to achieve the above object, the present invention comprises a crushing step of crushing the bark and bentonite mineral processing into powder; A powder mixture of 30 to 70% by weight of starch powder, 10 to 30% by weight of koi powder, 1 to 10% by weight of pine needle powder, 10 to 20% by weight of bentonite mineral powder, and 1 to 10% by weight of brown root powder, A mixing step of mixing at a volume ratio of 1: 4 to 1: 6; A stirring step of heating the mixture of Jiji water and the powder to 100 ° C. and stirring for 15 to 30 minutes; It comprises a aging step of naturally aging the heated and stirred mixture at room temperature for 18 to 20 hours; and comprises a method of producing a functional wallpaper for wallpaper.

In this case, the kerchi shell powder is preferably prepared by crushing the kerchi shell in a crusher after washing and drying the kerchi shell in an electric furnace at a temperature of 900 ~ 950 ℃ for 1 to 2 hours.

In addition, the functional paper for wallpaper according to the present invention is 30 to 70% by weight of starch powder, 10 to 30% by weight of pinot powder, 1 to 10% by weight of pine needle powder, 10 to 20% by weight of bentonite mineral powder and 1 to brown root powder. It consists of a powder mixture containing 10% by weight mixed.

The functional wallpaper for wallpaper according to the present invention configured as described above is harmless to the human body by constituting the wallpaper, excluding the use of chemicals, to suppress the occurrence of mold on the wallpaper, and to remove various contaminants in the room.

Hereinafter, the wallpaper for the wallpaper according to the present invention and a manufacturing method thereof will be described in detail.

The method for producing wallpaper for the wallpaper according to the present invention is largely composed of a crushing step, mixing step, stirring step and aging step.

First, the crushed bark and bentonite minerals mined in Yeongil Bay are crushed with a crusher and then processed into a particle size powder of about starch-based powder to be mixed.

10 ~ 30% by weight of the oyster shell powder crushed through the crushing step, 10 ~ 20% by weight bentonite mineral powder, 30 ~ 70% by weight starch powder, 1 ~ 10% by weight pine needle powder and 1 ~ 10% by weight of brown root powder A mixing step of mixing the mixed powder mixture and jijangsu at a volume ratio of 1: 5 is performed.

The cockle shell powder consisting of the main components as shown in Table 1 is prepared by the following method.

After inserting the bark taken from the clean water into the washer and washing it, the bark is calcined for 1 ~ 2 hours at 900 ~ 950 ℃ in an electric furnace, and then the bark is crushed in a crusher to prepare the bark powder. .

At this time, it is preferable to bake at an temperature of 900 ℃ in the electric furnace, the pore bark fired at the temperature of 800 ℃ was a state that the entire surface of the organic matter was not removed, as shown in Figure 1 of the pores that can exhibit the adsorption function There was not enough development. In addition, since the pore was calcined at a temperature of 1,000 ℃ as shown in Figure 2 pores are so developed that the strength of the shell is too difficult during the manufacturing process was difficult to use. On the other hand, the pore shell calcined at a temperature of 900 ℃ was satisfactory in the pore development and the removal of organic matter on the surface, as shown in Figure 3, the pores capable of the adsorption function was properly generated. Therefore, the most suitable firing temperature of the cortex is the temperature of 900-950 degreeC.

The main constituent mineral of the bentonite mineral composed of the main components shown in Table 2 is Montmorillonite, and a general chemical formula is [(Al.Fe) _1.67 , Mg _0.33 ] Si ₄ O ₁₀ (OH) ₂ (Na _0.33 ) It is composed of a little difference depending on the crystal structure. The crystal structure of montmorillonite has a layered structure as shown in FIG. 4, and is a 2: 1 type structure having one octahedral layer between two tetrahedral layers as a three-layer structure.

In the tetrahedral Si ⁺⁴ ions of the bentonite as described above, the negative charges are co-substituted by Al ³⁺ ions and Mg ⁺² and Fe ²⁺ ions instead of Al ³⁺ and Fe ⁺³ ions in the octahedron. Negative change occurs and Na ⁺ , Ca ⁺² , Mg ⁺² , H ⁺ ions are weakly attached to neutralize harmful substances.

As described above, the bentonite molecular structure is a multilayer structure, and spaces are formed at both ends of the multilayer structure, which are called both pores, and the far-infrared region in the empty space is processed by processing the bentonite to create more empty space inside the bentonite. Can store energy, and the empty space makes the adsorption force stronger.

Physical and chemical properties of the bentonite mineral powder as described above are shown in Table 3 below.
