BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a paper coating agent for coating a surface of paper, and more particularly, to fine mineral powders such as sericite, chlorite, illite, and zeolite. Is coated on paper such as wrapping paper, wallpaper, etc., to keep various agricultural products freshly packaged by strong adsorption power, anion substitution ability, and large anion release effect of minerals for a long time, while removing odor and removing residual toxic chemicals. The present invention relates to a method for producing a paper coating that effectively neutralizes the cavities and decomposes the toxicity of cement.

In general, the wrapping paper of paper, such as wrapping paper, wallpaper, etc. simply has a function to prevent the packaged goods from being damaged or to have a beautiful appearance. The role of neutralizing and removing the irritating odor generated was difficult to expect.

In addition, the wallpaper also has a function to make the wall beautiful, so it was difficult to expect a role to decompose the toxicity of cement generated from the cement wall.

Moreover, in modern times, agricultural chemicals use a large amount of pesticides to remove pests or weeds, so pesticides remain in the harvested agricultural products, and these residual pesticides have a bad effect on the human body. There is an urgent need for proposals for wrapping papers in which the toxicity of N is naturally neutralized and removed.

The present invention has been made in view of the above problems, and its purpose is to coat on paper, such as wrapping paper, wallpaper, and the like with a fine powder of mineral fine powders such as cerite, chlorite, elite, zeolite, etc. A method of producing a paper coating that can keep various agricultural products freshly packaged by substitution capacity and large anion release effect for a long time, remove odor, effectively neutralize the toxicity of residual pesticides, and decompose the toxicity of cement. It's in the box.

Features of the present invention for achieving the above object, the step of collecting minerals, such as Sericite (sericite), chlorite, illite, zeolite (zeolite); Crushing the collected minerals into coarse particles, respectively, removing impurities, and then drying them in a drying furnace to sufficiently dry moisture contained in the minerals while applying heat at 450 to 550 ° C.

Hereinafter, described in detail by the manufacturing process of Figure 1 attached to a preferred embodiment for achieving the above object as follows.

Example

Minerals such as sericite, succinite, illite and zeolite, which exist as natural minerals in nature, were collected (S10).

Subsequently, the collected minerals were put into each crusher and crushed into particles having a size of about 20 mm or less, and the particles were sorted to remove impurities, the minerals were put into a drying furnace, and then heated to about 500 ° C. When dried, the moisture contained in the mineral was sufficiently dried (S20).

In the step (S20), it is preferable to remove the foreign matter clinging to the surface of the minerals in the mining process to further include the step of sorting the crushed mineral particles, washed with water and then naturally dried.

The drying furnace is composed of a thermal kiln type and may be dried by adding minerals, but the method of drying by applying heat of about 500 ° C. or more while moving minerals to a conveyor moving through the kiln for about 10 to 20 minutes is mass production. It is preferable because it is possible.

Of course, in some cases, it is possible to inject minerals into a rotary furnace that is mounted to be inclined and heated so as to dry them by heat.

Subsequently, the dried minerals were put in a grinder and finely pulverized, filtered through a sieve having a particle size of 1750 mesh or more, processed into fine powders, and then stored in different containers (S30).

The grinder used a conventional grinder in which the cutters are rotated facing each other and grind by grinding by milling when the grinding particles become smaller in stages.

Then, 88% by weight of the acrylic emulsion, 4.5% by weight of sericite powder, 3.5% by weight of chlorite powder, 2.5% by weight of eliteite powder, and 1.5% by weight of zeolite powder were added to the stirrer. Injected and mixed evenly to prepare a paper coating (S40).

The stirrer allowed the mixture to be evenly blended using a conventional stirrer in which stirring blades mounted inside the tank were slowly rotated by the power of a motor.

When paper is coated with a paper coating material completed through the above-described manufacturing process and used as a wrapping paper for agricultural and aquatic products, natural materials such as sericite, chlorite, illite and zeolite are used. Since natural minerals that emit anions in the state are coated and coated, they can absorb and neutralize the toxicity of pesticides remaining in agricultural and marine products by the adsorption effect of fine particles of minerals. the occurrence of unwanted odor at the same time that can filter from occurring clay minerals are strong anion substituted ability hydroxyl (OH ^-), causing an oxidation reaction in the agricultural and marine products, by having to carry because that ions can be strongly reduced long-term to agricultural products stored Even if they are protected from corruption, It is.

In addition, when used as wallpaper, there is an advantage such as to decompose the toxicity of the cement by the natural mineral that emits the coated anion.

On the other hand, one of the most important and important materials included in the manufacturing process of the present invention, such as cerite, chlorite is known to not only emit negative ions in the natural state, but also generate a rotating electromagnetic wave (π-ray). Electromagnetic waves move forward from the free space to the speed of light and have a period of wavelength and their energy is proportional to the frequency {E = hv (E: energy, h: Planck's constant, v: frequency)}.

Among them, the rotating electromagnetic wave uses strong attraction force when the electromagnetic wave is transformed into the rotating electromagnetic wave by crystallization of the bond between atoms in which repulsive force or attractive force is acted on by Coulomb's law when two alternating charges are moving in space. It is known that the absorption of unnecessary biological energy in the human body slows down cancer treatment and growth rate, and the wavelength band of the rotating electromagnetic waves generated by this combination is capable of sterilizing harmful bacteria. From "Rotational Electromagnetic Theory" by Professor Oh Heung-kuk, School of Engineering)

Therefore, it is possible to maintain the freshness even by circulating for a long time by slowing the growth rate of the organisms packaged in the wrapping paper, and to prevent odor blocking and decay by sterilizing effect and adsorption of particulate matter.

On the other hand, the properties of the minerals used in the manufacturing method of the present invention are as follows.

It is able to remove the irritating odor by neutralizing by adsorbing and neutralizing the toxicity of the remaining pesticides. In addition, it is possible to adsorb and separate the strong alkali toxicity contained in cement. It is effective to prevent, and to activate the composition of the vegetation colonies growing in the raft block.

The chlorite is a mineral belonging to a monoclinic system, and the main component thereof is a hydrous silicate (Mg, Fe, Al) ₁₂ (Si, Al) ₈ O ₂₀ ( OH) ₁₆ .

In addition, chlorite is widely found in various kinds of sedimentary rocks, low-temperature metamorphic rocks, and igneous rocks deteriorated by hot water. By releasing and adsorbing and decomposing toxic substances, it is possible to remove and remove toxic and irritating odors of residual pesticides.

The illite has a mineral structure of clay structure, and chemical composition is composed of SiO₂, Al₂O₃, K₂O, specific gravity 2.6-2.9, chemical composition of (K, H ₃ O) Al ₂ (Si, Al ) ₄ O ₁₀ (H ₂ O, OH) ₂ , produced in aluminium-rich heterogeneous or tuff sedimentary rocks, and as a metamorphic mineral of hydrothermal deposits.

In addition, illite is a microporous structure, has strong adsorption and ion exchange functions, and it is a hardened cement product due to the characteristics of adsorbing particulate matter by separating anion and far infrared rays in a natural state or separating particulate matter having different sizes. CaCO ₃ , Ca (OH) ₂ , Na ₂ SO ₄ , Na ₂ CO ₃ , K ₂ CO _{3 It is possible} to induce chemical substitution and mass conversion of components to adsorb and separate the strong alkali toxicity contained in cement. Rather, it suppresses the whitening effect and blocks the toxicity of cement.

The zeolite is a mineral that is an aluminum silicate hydrate and is produced in a cavity or a hot pole of a basic igneous rock such as basalt and whirlwind, and the crystal structure of each atom is loose and fills therebetween. Even if the moisture is released at high heat, the skeleton remains the same, so that it can be used as a molecular sieve to adsorb other particulate matter or separate particulate matter of different sizes.
