Description

Specification

Name of Invention: Eco-friendly Natural Decomposition Mulching Materials

[1] The present invention relates to an environmentally friendly biodegradable mulching material.

[2]

Background

[3] The term "covering" the surface of arable soil when growing crops,

It is used for soil erosion prevention, soil water retention, low temperature control, weed control, soil pollution prevention, etc. In more detail, it is a method of covering the soil surface of cultivated crops with roots. Erosion prevention was performed to prevent the crops from being lost to water damage, and to control water evaporation within a certain range by suppressing a part of the water evaporation essential for growth.

[4] In the early stages of the mulching material used in such mulching, eco-friendly materials such as rice straw, chopped straw, grasses, etc. were used.However, materials such as polyethylene and polyvinyl chloride, which are easy and secured to work, are used today. .

[5] However, the above-mentioned vinyl materials have to be collected after being buried in the soil, unlike vinyl for vinyl house exposed on the road surface.

Not only was the work intensity high, but it was also difficult to remove by force due to the aging of rural workers, and most vinyl mulching papers remained permanently in the soil.

[6] In particular, vinyl mulching paper remaining in the soil is a very poor air permeability due to the nature of the material, which is a major cause of soil pollution. The problem is that vinyl mulching paper, which is not removed, grows year by year, and the recovery rate is less than 55%. It's egg.

[7] In order to solve this problem, researches are being conducted on natural degradable mulching materials.

[8] For example, Korean Patent Publication No. 10-2005-0036627

Mulching film and its manufacturing method include stearic acid, heavy calcium carbonate,

Vinyl Ketone Copolymer, Polyethylene Wax, Lactose, Ethyl Acetate,

Mixed methacrylate, powdered milk, isobutyl alcohol, benzene and LMPE

The biodegradable compound is made of LDPE, LLDPE, HDPE, PSP and PP, or a combination of these plastic resins.

The use of plastic resins as the base polymer limits the natural degradation by soil microorganisms.

[21] Hereinafter, each configuration of the present invention will be described in detail. [22] The present invention relates to an eco-friendly biodegradable mulching material, which includes natural cotton, fiber materials, natural fibers, natural adhesives, pigments, and additives. The natural cotton provides organic material to the soil and also controls soil humidity. It is possible to use wool, goose down, silk wool, cotton wool, but not limited to this. However, it is desirable to use cotton wool to provide a lot of organic matter to the soil and to adjust the soil's humidity. It is good to be able to adjust it.

[23] It is also preferable to include 16 to 36% by weight of natural cotton, in the above range

In the case of natural brushes, the final shape of the natural mulching material produced can be properly formed and the porosity can be improved to improve the respiration of the soil.

The fiber raw material may be natural rayon, natural polishing or a mixture thereof, and the natural rayon may be one or two or more selected from viscose ray, copper ammonium ray, rio sal and acetic acid fiber.

[25] The natural polishing may be one or more mixtures selected from Ramie, linen, Hax, hemp, hemp, jute, manima and sisal. This is not a limitation.

[26] The natural abrasive is one of the oldest fibers used by human beings, and it is particularly used in high-grade clothing for summer because it is highly breathable even in natural fibrosis, absorbs moisture and dissipates and gives cool feeling and is not easily polluted. However, these words have a flaw that makes it difficult to spin with fine yarns and is easy to cause wrinkles.Therefore, these defects are mixed with other fiber materials such as synthetic fibers or specially processed to prevent wrinkles and smooth out. It is necessary to supplement the summer with high-grade clothing.

[27] In particular, hemp is called hemp or marijuana, and is distributed throughout the world in subtropical and subtropical regions, except for one large area, and is composed of more than 100 varieties and strains, such as CBC, CBG, It contains about 60 main ingredients such as CBN, CBD, THC, and 360 auxiliary substances.

Functional substances, called cannabinoids, are synthesized in the cells of hemp and then converted into a number of intermediates that eventually accumulate in plants in the form of CBD or THC.

[28] Hemp takes the fibers from the stem and pulls the ship's ropes and bags.

The oil from the seeds has been used as a raw material for paints and varnishes, and as a medicinal product from physiologically active materials from the bracts of female flowers.Because of the various uses of hemp, from around 5000 BC

It began to grow in China (Manchuria). Since then, it has been introduced to Southeast Asia, Europe, North America, South America and Africa.

[29] Hemp fibers, in particular, are not only the hardest and toughest known fibers in the world, but also have a very long fiber length of l to 5 m, and have been used as ship ropes because of their strong resistance to salting and getting wet. With demand Increasing prices have resulted in the replacement of synthetic resin products. In our country, hemp fibers have traditionally been used as one of the most important clothing items, but in recent years there has been a sharp decline and it has become increasingly difficult to find traces of hemp in the West. It is being changed again and again, that is, hemp is used for the cover of the interior decoration, curtains, bedding products, carpet, etc., and hemp fiber is used for the production of hard paper box,

By adding about 25% of hemp fiber to wood tiles, compressed wood tiles are produced that dramatically improve the texture and robustness of wood tiles. Hemp fiber is a natural fiber that increases the strength and layer resistance of composites. It is used as a synthetic polymer additive because it improves thermal stability, and provides antibacterial, UV blocking, and water blocking functions.

[30] Recently, hemp wave, ultraviolet ray, electromagnetic wave blocking, antibacterial action, far infrared ray emission and soundproofing have been demonstrated in the fabric developed by Hamp Korea, a domestic hemp company.

In the present invention, it is preferable that the fiber raw material contain 7 to 17% by weight, and if it is included in the above range, the ultraviolet ray blocking function can be improved and the tensile strength can be improved.

[32] The natural fiber of the present invention is easily decomposed when using a mulberry material manufactured from natural fiber extracted from one or more selected from coco ¾, almond, sweet and sour or bamboo. ， It is desirable because the tensile strength is improved.

[33] It is preferable that the natural fiber contains 3 to 23 wt. ¹ ¾, and if it is included in the above range, the natural decomposition of the mulching material can be facilitated, and the tensile strength of the eco-friendly biodegradable mulching material manufactured is improved. good.

In the present invention, it is preferable to use vegetable glue or animal glue as the natural adhesive.

[35] The vegetable glue may be any one or two or more mixtures selected from seaweed, seaweed, seaweed, radish, corn starch, starch flour, rice husk flour, seaweed, agar, hardwood and chip leaf powder, but is not limited thereto. Not the above

Animal glue can use any one or more mixtures selected from gelatin, casein, mammalian bone and leather, collagen, mica, feldspar powder, diamond stone powder, expanded powder, and mine powder. It doesn't work.

However, it is preferable to use gelatin, kelp, or agar, and it is more desirable to use chima.The above-mentioned kelp is rich in laminarin, an adhesive ingredient, which improves adhesion and may improve durability. Not only that, but also the liquidity can be secured, so it is easy to use.

[36] In addition, the natural adhesive may contain 15 to 35% by weight of the mixture to improve the viscosity of the complex to ensure fluidity and ease of operation, and to increase the adhesive force, thereby improving mechanical properties such as tension and elasticity of the cotton. desirable. [37] In the present invention, any one or more mixtures selected from squid ink, charcoal liquor, charcoal powder, animal blood and clam secretion can be used as the pigment, and the color is black and can be expressed from ultraviolet and direct sunlight. It is effective to protect crops.

[38] It is preferable that the above-mentioned pigments contain 1 to 2% by weight, in the above range.

If it is included, the black color is excellent, and the blocking rate of ultraviolet rays and direct sunlight can be improved, which can help the growth of crops.

[39] Additives to the present invention include volcanic powder, zeolite powder, silicate powder,

It can contain any one or two or more mixtures selected from natural antibacterial clam powder or silicate aqueous solution.As it can absorb pollutants by using absorbing volcanic acid powder or zeolite powder, it can improve the power of posture. When the silicate aqueous solution is added, the antimicrobial activity is improved, which may play a role of diluting harmful components that may remain in the mixture of the present invention, thereby improving soil quality.

It is preferable that the additive is included in an amount of 0.1 to 20% by weight, and if it is included in the above range, the soil intelligence can be improved and the crop growth can be further improved.

[41] The eco-friendly biodegradable mulching material according to the present invention can be manufactured in the form of felt, and since it is composed only of natural materials, it is possible to breathe the soil even if it is covered near the roots of crops, and it is naturally decomposed by the soil microorganisms and removed separately. It also has the advantage of not needing the process. It also releases various microorganisms to prevent environmental pollution, and it is useful for microorganisms in the process of decomposition of mulching materials, and it prevents the penetration of sunlight to suppress germination and growth of crops. There are advantages to promoting growth.

[42] Furthermore, all are made of natural materials, which are expected to be used as medical surgical mats, medical mats, and eco-friendly showback bags, which are harmless to the human body. The system's refining agent or styro product is expected to be able to compensate for the disadvantages that have been harmed rather than the warming effect because the moisture inside the product is kept frozen because the moisture condensation, snow and rain are not discharged outside.

[43]

Effects of the Invention

[44] According to the present invention, the eco-friendly biodegradable mulching material is composed entirely of natural materials.

So it is possible to breathe the soil even if it is covered near the crop roots, and it is naturally decomposed by soil microorganisms, so there is no need for a separate removal process, which has the effect of reducing manpower. Also, it releases various microorganisms to prevent environmental pollution. In particular, it is a useful food for microorganisms during the decomposition of mulching materials, and it prevents the transmission of sunlight to inhibit germination and growth of weeds, and restores natural ecosystem order and useful microorganisms. It has the effect of being a good fermented compost material due to growth.

[45] Furthermore, since all are made of natural materials, they are expected to be used as medical surgical mats and medical mats without harming the human body. Furthermore, they are excellent in breathability and can easily release moisture. Moisture is not discharged outside due to internal blood flow phenomenon, snow and rain, so it remains frozen inside the product.
