Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper and a method of manufacturing the wallpaper. More particularly, the present invention relates to wallpaper produced using a corn husk and a method of manufacturing the wallpaper.
Wallpaper is a building finishing material used to improve the residential environment or to change the feel and atmosphere of the building according to the taste of the customer by being spread over the wall or ceiling of the building.
In the past, wallpaper has been used exclusively to decorate walls, but in recent years it has added other functions besides basic decoration. Especially, there is an urgent need for the development of wallpaper that can help health from harmful indoor environment.
The harmful indoor environment becomes the main cause of the air pollution. Such air pollution becomes more severe by using many chemicals used in the housing construction and the chemical treated materials, and the asthma and the respiratory system of the human body may be obstructed, causing dizziness It is also said.
In the air, material elements such as nitrogen, oxygen, carbon dioxide, and hydrogen are mixed and floating in the state of cations and anions, respectively. You can experience a refreshing feeling around a waterfall, around a fountain, or in a stream, because there are many negative ions in these places.
However, in cigarette smoke, automobile exhaust gas, factory smoke, and many electronic appliances in the home, a large amount of positive ions are generated, which decreases the amount of anions and increases the amount of positive ions.
Since wallpaper surrounds a large area of the room, it can directly affect the indoor air pollution, and accordingly, a lot of functional wallpaper is being developed.
The above-described technical structure is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide wallpaper made using a corn husk and a method of manufacturing the same.
According to an aspect of the present invention, there is provided a method for manufacturing a corn husk, comprising: boiling and then cutting a corn husk; Crushing the boiled corn husk after adding boiled corn husk and water to the mixer apparatus; Filtering the pulverized boiled corn husk in the mixer apparatus; And a step of making the pulverized boiled corn husk filtered through the cornice into a wallpaper form and drying the corn husk.
The method of the present invention may further include the step of putting loess powder into the pulverized boiled corn husk in the mixer device.
The boiled corn husk is 25 to 35 wt%, the water is 50 to 70 wt%, and the loess powder is 7 to 15 wt%.
When making the wallpaper, a gauze cloth may be laid on the basket, and the ground boiled corn husk to which the loess powder is added may be spread on the upper surface of the gauze cloth.
The pulverized boiled corn husks may be spread out to form the wallpaper, dried in the shade, and then dried with an iron and dried again.
Natural pigments or natural substances may be further added to the corn husk.
According to another aspect of the present invention, there is provided a wallpaper made using a corn husk, which is produced using a corn husk and an ocher flour.
Embodiments of the present invention are useful for health because the antimicrobial and moisture absorptive and desorptive properties are improved because the corn husk is used to produce wallpaper, and the volatile organic compounds are not detected and the formaldehyde levels are low to reduce the sick house syndrome .

In order to fully understand the present invention, operational advantages of the present invention, and objects achieved by the practice of the present invention, reference should be made to the accompanying drawings and the accompanying drawings which illustrate preferred embodiments of the present invention.
Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.
FIG. 1 is a flowchart schematically illustrating a method of manufacturing wallpaper using a corn husk according to an embodiment of the present invention. Referring to FIG.
As shown in these drawings, a method of manufacturing a wallpaper using a corn husk according to the present embodiment includes a step (S100) of cutting and cutting a corn husk, a step (S100) of adding a boiled corn husk and water to a mixer apparatus, A step (S200) of crushing the corn husk, a step (S300) of putting yellow loam in the boiled corn husk pulverized in the mixer apparatus, a step (S400) of filtering the boiled corn husk pulverized in the mixer apparatus (S400) And drying the pulverized boiled corn husks filtered into a wallpaper form (S500).
In this example, corn husks are used to produce wallpaper, in which 60 to 70% of the corn husk is composed of cellulose and hemicellulose, and 5 to 15% is composed of lignin. Cellulose is the basic structure of plant cell walls, and lignin is a substance that exists in large amounts on plant cell walls. Lignin acts to attach cells to each other, and when it accumulates, it stops cell division and becomes a hard tissue.
In this embodiment, it is possible to make wallpaper with a corn husk because the lignin in the corn husk causes the cells to stick to each other. In addition, about 1,000 to 5,000 glucose are bound to cellulose, and pulp, which is a raw material for making cotton or paper, is 90% cellulose. So you can make wallpaper with cellulose and lignin.
In this embodiment, the corn husks are first put into water and boiled for about one hour and cut.
In this example, 100 g of the shell is put into a mixer apparatus at a ratio of 200 ml of water, and finely pulverized. In this embodiment, the corn husk can be formed into two types of fine particles and coarse particles to produce wallpaper. If the corn husk is in the form of fine particles, you can spend more time with the blender. For example, if the corn husk is in the form of fine particles, it can go to the mixer apparatus for 5 minutes, and if it is in the form of thick particles, it can go to the mixer apparatus for 3 minutes. For reference, in this embodiment, the mixer apparatus includes a general mixer used in the home.
Next, filter the corn husk on the mixer unit and put the gauze cloth on the basket, put the corn husk particles on it, and lay it evenly thin.
In this state, remove the water, then dry in the shade of the wind, then dry with an iron.
Meanwhile, in this embodiment, 20 g of the loess powder can be further added after the corn husks are put into the mixer apparatus. If wallpaper is made by adding yellow clay powder as in the present embodiment, flame retardancy is improved and carbon monoxide is reduced compared to adding corn husks alone.
In the present embodiment, boiled corn husk may be added in an amount of 25 to 35 wt%, water may be added in an amount of 50 to 70 wt%, and yellow loam may be added in an amount of 7 to 15 wt%. In the present embodiment, the yellow clay powder has an effect of reducing flame retardancy and carbon monoxide. However, when the yellow clay powder is added too much, the wallpaper can not be formed properly. Therefore, the yellow clay powder may be added in an amount of 7 to 15% by weight, 12% by weight.
In addition, the present embodiment can be utilized as a functional wallpaper by adding a natural pigment or a natural substance to the corn husk. For example, in this embodiment, the corn husks are put into a mixer apparatus, finely papermaked, and then paprika natural pigment and pine leaf powder can be put into a variety of scented and functional wallpaper.
FIG. 2 is a graph showing antimicrobial activity of a wallpaper and a general wallpaper produced using the corn husk according to the present embodiment.
Hereinafter, an antimicrobial test example of the corn husk wall paper and the general wallpaper produced by this embodiment will be briefly described.
The corn husk wallpaper and the ordinary wallpaper produced by this embodiment are cut to the same size, sprayed with sugar water, and sealed with a lap. Then we observe changes in the state of the wallpaper and the corn husk wallpaper.
After about a day or so, the mold (as shown in FIG. 2) appeared on the normal wallpaper (left picture). On the other hand, corn husk wallpaper was damp, but did not mold.
The results showed that corn husked wallpaper had antibacterial properties compared to ordinary wallpaper.
FIG. 3 is a result of experiments on the moisture absorptive and desorptive property of the corn husk wallpaper and the general wallpaper according to the present embodiment, and FIG. 4 is a graph showing the experiment result data of FIG.
Hereinafter, the results of experiments on the moisture absorptive and desorptive properties of the general wallpaper and the corn husk wallpaper will be briefly described with reference to FIG. 3 and FIG.
As a result of the experiment, silk wallpaper and paper wallpaper did not change much as shown in FIG. 4, and the change in the graph when the corn husk wallpaper was returned from 75% humidity to 50% was large.
This indicates that it is excellent in moisture absorption and moisture-proofing ability, and it is possible to control the humidity itself, which can help the health of the human body.
5 is a table showing results of pollutant emission test results of the corn husk wallpaper and the general wallpaper of the present embodiment.
Hereinafter, the amounts of pollutants, volatile organic compounds (benzene, toluene, ethylbenzene, xylene styrene) and formaldehyde in general wallpaper and corn husk wallpaper will be briefly described.
First, a wallpaper is put into a 26 ml volume glass tube where a high purity nitrogen gas is discharged using a sample extractor. Next, one liter of air is collected for 30 minutes using a VOC trapped adsorption tube. Formaldehyde collects 1 liter of air for 30 minutes using DNPH (Dinitrophenyl hydrazine) cartridge, a reagent that reacts with the sample material and produces a specific color.
The analysis of volatile organic compounds was carried out by using the collected adsorption tubes using five kinds of substances regulated in the certification of environment-friendly building materials in Korea using the thermal desorption-gas chromatograph-mass spectrometer (TDA-GC / MSD), benzene, toluene, ethylbenzene, xylene, The concentration of styrene was analyzed.
Formaldehyde analysis used high performance liquid chromatography (HPLC) for the collected cartridges.
As a result of the analysis, as shown in Fig. 5, the volatile organic compounds evaluated in the corn husk wallpaper were not detected when the eco-friendly building material was certified. Formaldehyde was detected because of the adsorption of some formaldehyde in the atmosphere due to the nature of the corn husked wallpaper where the fine fibers are exposed on the surface.
On the other hand, in the case of ordinary wallpaper, toluene (14.36), xylene (1.57) and formaldehyde (119.08) were emitted at a high concentration, which is a threat to human health.
6 is a graph comparing the flame resistance of a corn husk wallpaper and a general wallpaper according to the present embodiment.
As shown in FIG. 6, when the wallpaper is lighted, it can be observed that the fire wall is generally entirely fixed as compared with the corn husk wallpaper. In other words, corn husk wallpaper had longer burning time than general wallpaper.
Also, in case of smoke generation, both regular wallpaper and corn husk wallpaper were generated.
Furthermore, the coffee cup with the corn husk wallpaper was clean, but the cup with the ordinary wallpaper was sooty.
The smoke of the corn husk wallpaper is not irritating by the smell of the straw, but the gas generated during the burning of the ordinary wallpaper stimulates the eyes and nose and smells like chemical burning.
Fig. 7 is a graph comparing flame retardancy of a corn husk wallpaper, an ocher corn husk wallpaper and a general wallpaper according to the present embodiment.
First, when the wallpaper was lit for three seconds with a lighter, the wallpaper was burned with fire, and the corn husk wallpaper was also burnt, but the ocher corn husk wallpaper was not attached to the fire.
Next, in case of smoke appearance, white smoke with charcoal was generated in the case of corn husk wallpaper and ocher corn husk wallpaper, and the ordinary wallpaper smelled of black smoke, smell of filling chemical which gives strong irritation to the nose and nose .
Last 90 seconds after the fire was over, the ocher corn skin wallpaper was self-extinguished. As a result of observing the area of the carbonized area by spraying water on the wallpaper, it was found that the carbonized area was broad in the order of the ocher corn husk wallpaper> the corn husk wallpaper> the ordinary wallpaper.
As a result, ocher corn husk wallpaper has self-extinguishing function and flame retardancy, so it can be seen that ocher corn husk wallpaper is the safest wallpaper in case of fire.
FIG. 8 is a table measuring the carbon monoxide content of corn husk wallpaper, ocher corn husk wallpaper and general wallpaper according to the present embodiment, and FIG. 9 is a graph showing the numerical values of FIG.
First, the experimental method of this embodiment will be briefly described.
Prepare general wallpaper, corn husk wallpaper, ocher corn husk wallpaper, acrylic box, carbon monoxide meter, glass bottle.
Put a carbon monoxide detector and a glass bottle in a cube (1.25cm) transparent acrylic box. Place the wallpaper with the fire in a transparent acrylic box with the lid open, close the lid of the acrylic box to seal it, and compare the values of carbon monoxide.
As for the general wallpaper, the maximum value of carbon monoxide was 200ppm in the fourth experiment, and the corn husk wallpaper and the ocher corn husk wallpaper had a result of 40 ~ 50ppm, which was much lower than that of the ordinary wallpaper.
Compared to the size of the transparent acrylic box, this figure shows that there is almost no carbon monoxide when considering that the carbon monoxide emitted from a mackerel and 200g of pork is 22.23 ppm without turning on the hood of the kitchen.
Therefore, it can be seen that corn husk wallpaper and ocher corn husk wallpaper do not emit toxic gases in the event of a fire.
10 is a graph comparing the thermal stability of a typical wallpaper with a corn husk wallpaper.
As shown in FIG. 10, the final weight of the corn husks at 600 ° C was the lowest at 2.1%, followed by 18.2% for paper wallpaper and 38.1% for silk (PVC) wallpaper.
Wallpaper made from pure corn husks proves to be a pure natural material because it exhibits relatively low ash (weight of burnt ash) compared to wallpaper with other additives.
The point at which weight loss began was in the order of paper wallpaper> corn husk wallpaper> silk wallpaper.
As a result, when using corn husk wallpaper, it can be seen that toxic gas does not come out and thermal stability is higher than silk wallpaper in case of fire.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
