Hereinafter, the paper mulching paper according to the first embodiment of the present invention will be described first with reference to FIG. 1.

The paper mulching paper according to the first embodiment of the present invention is composed of a first paper sheet 100, a frame member 200 and a second paper sheet 300, as shown in FIG.

The first paper sheet 100 and the second paper sheet 300 may be made of waste paper, general pulp, duck pulp, abaca pulp, etc., such first paper sheet 100 and second paper sheet 300 ) May be coated on at least one of the mixed coating solution in one layer or multiple layers, and may be coated on one side or both sides.

The coating layer may be formed by coating a material mixed with a mineral and a natural adhesive on one or both sides of at least one of the first paper sheet 100 and the second paper sheet 200 to supply nutrients to crops and soil.

The mineral material may include at least one of germanium, bentonite, bamboo charcoal, ocher, maculite, jade, cerium, rosacea, and lanthanum, and the coating layer may be formed by coating a mineral solution in which mineral and water are mixed.

The mineral solution may be prepared by using 4.5 to 18 parts by weight of mineral based on 100 parts by weight of water, specifically, 0.5 to 2 parts by weight of germanium, 0.5 to 2 parts by weight of bentonite, 0.5 to 2 parts by weight of bamboo charcoal, based on 100 parts by weight of water Part, 0.5-2 parts by weight of ocher, 0.5-2 parts by weight of mackban stone, 0.5-2 parts by weight of jade, 0.5-2 parts by weight of cerium, 0.5-2 parts by weight of injection and 0.5-2 parts by weight of lanthanum may be mixed.

Germanium has the effect of killing harmful fungi. In addition, germanium has the effect of emitting far-infrared rays, especially when the amount of germanium is less than 0.5 parts by weight, the effect of killing harmful fungi is low, and when the amount of germanium is more than 2 parts by weight, even fungus beneficial to crops or soil Since it can be killed by inhalation, the blending amount of germanium is preferably 0.5 to 2 parts by weight.

Bentonite is an interlayer structure that performs the function of interlayer inhalation and killing of harmful fungi present in the soil, and such bentonite expands 10 to 20 times its weight and discharges minerals through ion exchange, thereby supplying nutrition to the soil and crops. It works.

Particularly, when the blending amount of bentonite is less than 0.5 parts by weight, the effect of killing harmful fungi is low, and when the blending amount of bentonite is more than 2 parts by weight, there is a possibility that even fungi beneficial to crops or soil may be inhaled and killed, so the blending amount of bentonite Silver is preferably 0.5 to 2 parts by weight.

Bamboo charcoal has an adsorption action, and can remove odors generated during decomposition. Such bamboo charcoal has a sterilizing power, and thus functions to inhibit bacterial growth during decomposition.

Particularly, when the amount of bamboo charcoal is less than 0.5 part by weight, the effect of inhibiting bacterial reproduction is low, and when the amount of bamboo charcoal is more than 2 parts by weight, the problem of suppressing the propagation of bacteria required for decomposition may occur. Silver is preferably 0.5 to 2 parts by weight.

Ocher is a binder of natural ingredients that are harmless to the human body, and these ochers are iron (Fe), magnesium (Mg), sodium (Na), kali (K2O), mina (A _l2 O ₃ ), calcium (CaCO ₃ ) and silica ( SiO ₂ ), etc., and yellow soil is a yellow mineral composed of 0.05 to 0.01 mm silt particles, and emits a large amount of far infrared rays.

The loess has a humidity control effect. Specifically, the loess radiates moisture when drying, and when the humidity is high, it absorbs moisture to control the amount of water supplied to crops.

In addition, ocher has a function of removing odors and has a sterilizing function, thereby preventing the crops from being infected with bacteria.

In particular, when the amount of loess is less than 0.5 parts by weight, the effect of preventing bacterial infection is reduced, and when the amount of loess is more than 2 parts by weight, the space between soils is narrowed due to the unique viscosity of loess when mixed with the existing soil. As the amount of oxygen penetrated between spaces decreases, the decomposition rate of the recycled paper may be delayed, so the blending amount of ocher is preferably 0.5 to 2 parts by weight.

Malvanite can improve water quality by weakly alkalizing water. In addition, mabanseok can be expected to have the effect of supplying clean water to crops by decomposing harmful bacteria in the water quality.

When the blending amount of pulverizing stone is less than 0.5 part by weight, the water quality improving effect may be low, and when the blending amount of pulverizing stone is more than 2 parts by weight, it is possible to decompose even beneficial bacteria in the water quality, so the blending amount of pulverizing stone is preferably 0.5 to 2 parts by weight.

Jade has the effect of decomposing harmful wastes. When the amount of jade is less than 0.5 parts by weight, the effect of decomposing wastes may be negligible, and when the amount of jade is more than 2 parts by weight, the rate of decomposition of mulching paper may be delayed. 0.5 to 2 parts by weight is preferred.

Cerium acts to activate the cultivation speed of crops. When the amount of cerium is less than 0.5 parts by weight, the effect of improving the cultivation of crops may be negligible. When the amount of cerium is more than 2 parts by weight, the decomposition rate of mulching paper is delayed. Since it can be, the amount of cerium is preferably 0.5 to 2 parts by weight.

Injection is an underground mineral with a red color, and the effect of activating the cultivation speed of crops can be expected.

In particular, when the blending amount of the injection is less than 0.5 parts by weight, the effect of improving the cultivation of crops may be insignificant, and when the blending amount of the injection is more than 2 parts by weight, the decomposition rate of mulching paper may be delayed, so the blending amount of the injection is 0.5 to 2 parts by weight. desirable.

Lanthanum performs a function of activating the cultivation speed of crops. In particular, when the amount of lanthanum blended is less than 0.5 parts by weight, the effect of improving cultivation of crops may be negligible. Since the amount of lanthanum may be delayed, 0.5 to 2 parts by weight is good.

In addition, other minerals may further include at least one of zeolite, kaolin, diatomaceous earth, and talc. In this case, in addition to the existing mineral solution, 100 parts by weight of water, 0.5 to 1 part by weight of zeolite, 0.5 to kaolin 1 part by weight, diatomaceous earth 0.5 to 1 part by weight and talc 0.5 to 1 part by weight may be added.

Zeolite can use natural zeolite, which is one of crystalline aluminosilicates. Zeolite refers to a group of white or colorless hydrous aluminum silicate minerals whose main constituents are sodium, calcium, and potassium, similar to feldspar.

Zeolite has fine pores, molecular sieve action and cation exchange ability, zeolite can be used as ion exchanger, adsorbent and catalyst, zeolite has the function of removing harmful substances such as heavy metals and dioxins, and zeolite has the action of nitrosamine Can be reduced.

Kaolin is a material with a high water absorption rate, and kaolin has a property of sticking because of its high water absorption.

Diatomaceous earth is classified according to the physicochemical use of the product, and diatomaceous earth is formed of a myriad of porous materials, and each particle has a very irregular shape, resulting in a porosity of 80 to 95% when forming a filter cake. It forms many of the capillaries resulting from this.

In addition, diatomaceous earth can be used as an absorbent because it has good filterability. Specifically, diatomaceous earth can absorb liquids 2-3 times larger than its own weight because it has internal pores like zeolite, so diatomaceous earth solidifies the liquid. It has excellent absorbency and can prevent the absorbed material from leaking again.

Talc is a soft rock with magnesium as its main component. Talc can nourish the soil.

As described above, the paper mulching paper according to the first embodiment of the present invention is formed of a paper material, not a synthetic resin material, so that, unlike the mulching paper of a synthetic resin material to be recovered after use, it rots and mixes with soil over time. Therefore, it is possible not only to reduce the use of manpower due to recovery, but also has the advantage of decaying paper and acting as a fertilizer.

On the other hand, when the mulching paper is composed of only the above-described first paper sheet and the second paper sheet, the strength is weak compared to the mulching paper formed of a conventional vinyl material, so there is a problem that it is well photographed when the mulching paper is coated or when it rains.

Moreover, when moisture comes in contact with the mulching sheet for the growth of rain or crops, the strength of the mulching sheet made of paper becomes weaker, and there is a problem that it is difficult to exert a function.

In order to prevent such a problem, the paper mulching paper according to the first embodiment of the present invention is to place the frame member 200 between the first paper sheet 100 and the second paper sheet 300 as shown in FIG. 1. Can.

In particular, the frame member 200 has a net structure formed by crossing each other with biodegradable natural yarns.

In particular, the above-described frame member 200 is made of a biodegradable yarn to be biodegradable together with the first paper sheet 100 and the second paper sheet 300 after a certain period of time has passed, and the biodegradable yarn is knitted into a mesh structure It is preferable to use the one prepared.

However, of course, the frame member 200 may be formed on the first paper sheet 100 at regular intervals to supply a plurality of yarns in the longitudinal direction and the rotational direction, respectively.

At this time, the biodegradable yarn is PCL [Poly(ε-caprolactone)], PLA[Poly(lactic acid)], Diol/Diacid-based Aliphatic polyester, PG[Poly(glycolic acid)], Poly(phosphate ester), Poly(phosphazeneene) ), PHB (poly-hydroxy butyric acid), and the like, and the biodegradable yarn is prepared by melting and spinning a biodegradable resin such as PCL resin, followed by stretching and cooling.

As the frame member 200 is formed between the first paper sheet 100 and the second paper sheet 300, the strength of the paper mulching paper is increased, so that it is not easily torn during the mulching operation, and is excellent in workability. There is a natural environment-friendly advantage, such as biodegradation with the first paper sheet 100 and the second paper sheet 200 after the lapse of time.

On the other hand, it is preferable to apply a cloth adhesive in order to adhere the above-described frame member 200 on the first paper sheet 100, and natural adhesives such as grass of rice or bran, dhv glue, pine resin, starch extract, etc. It is preferred to use materials.

In addition, at least one of the first paper sheet 100 and the second paper sheet 300 of the paper mulching paper according to an embodiment of the present invention may be formed by mixing pulp, water and charcoal powder, and furthermore, such charcoal powder May be included in the frame member 200.

When the charcoal powder is included in the manufacture of any one of the first paper sheet 100, the second paper sheet 300, and the frame member 200, it can effectively block sunlight caused by this, and as a result, weed growth. Can be suppressed.

Furthermore, when biodegradation of paper mulching paper, charcoal powder accumulates in the soil, so it remains in the soil and adsorbs pesticides or chemical fertilizer components that acidify the soil, neutralizes the acidified soil, and adsorbs and insolubilizes heavy metals present in the soil. Through it, the risk of heavy metals that can accumulate in the human body can be reduced, and anions or far infrared rays generated from the charcoal itself activate microorganisms in the soil to restore the soil ecosystem, and minerals abundantly present in the charcoal are minerals lacking in the soil Can supplement.

On the other hand, if the entire surface of the above-mentioned paper mulching paper is clogged, it is difficult to drain rainwater, and there is a problem that rainwater accumulates on the top of the paper mulching paper.

In order to prevent such a problem, a mulching paper with a hole for drainage has been proposed, but there is a problem in that a lot of attention is required when installing the paper mulching paper because installation is slow or the paper mulching paper is frequently torn.

Therefore, the paper mulching paper according to the first embodiment of the present invention has an incision that is commonly penetrated through the first paper sheet 100, the second paper sheet 300 and the frame member 200 in order to solve the above-mentioned problems. Can be formed.

Specifically, such an incision part maintains a state where one side is attached to the paper mulching paper, and the other side penetrates the incision surface while penetrating the first paper sheet 100, the second paper sheet 300, and the frame member 200 in common. It is configured to form.

At this time, since the incision is formed in a state where one side is attached to the paper mulching paper, the manufacturing process is simplified and the manufacturing time is also reduced.

In addition, the paper mulching paper according to the second embodiment of the present invention may further include a reflective film 400 attached to the upper surface of the second paper sheet 300 as shown in FIG. 2.

The reflective film 400 is configured to reflect the incident sunlight again, thereby preventing the temperature inside the paper mulching paper from becoming higher than a preset standard.

Furthermore, the reflective film 400 is also preferably formed of a material that can be biodegradable, such as the first paper sheet 100, the second paper sheet 300, and the frame member 200 described above.

As described above, the present invention has been described in detail with reference to examples, but the present invention is not limited to the above embodiments, and may be modified in various ways, and may have ordinary knowledge in the art within the technical spirit of the present invention.
