DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a soil disintegrable rubber composition suitable for use as a potting material for sticking to soil attached to plant transplant roots, and a root for plant transplants produced using the same. Rubber band, rubber tape,
The present invention relates to a rubber net and a binding cloth.

[0002]

2. Description of the Related Art In transplanting, if the roots are exposed to the sun or wind, the root viability of the roots is reduced. In general, the potted soil that adheres to the roots at the time of excavation is held and transported as it is, and excavated at a predetermined place. It is embedded in the hole as it is, but in order to improve the efficiency of holding potted soil that adheres to the root during transportation, in Japan, seedlings such as boxwood and satsuki attach to the root with straw, linen or rice paddy, straw. The pot soil is wrapped and tied with a rope. By the way, the pot value of the seedlings is zero because the pot soil that adheres to the roots during transportation is poorly retained and the roots that have adhered to the roots are dislodged and the roots do not take root after transplanting. However, due to the lack of binding workability, a method has been proposed in which a rubber band is used instead of a fly to bind linen, straw or straw. By the way, the rubber band is stretched, and the potting soil attached to the root wrapped with burlap or straw is wrapped with straw.
The ability to work with no binding is high, and even amateurs can easily bind. If a rope is used, the skilled worker has only 300 abilities a day. Also, after transportation and transplantation, it is desirable that the binding of the potted soil attached to the roots collapses earlier in the soil in order to improve root viability and growth, so the disintegration in the soil is much slower than the rope. When the rubber band is buried in the soil, some workers bury it as it is, but it seems that there are many workers who remove the rubber band and bury it. In particular, in order to bury potting soil attached to the roots of plant trees used for greening of public institutions in the soil while surrounding it, it may be mandatory to wind it with a rope. On the other hand, in the case of large and medium trees, as shown in Fig. 1, the pot soil attached to the roots is wrapped with linen cloth, rice cake, and straw, wrapped around the neck with a rope, and tied with the rope. Alternatively, as shown in FIG. 2, the pot soil attached to the root is tightened, and the pot soil attached to the root is wound with a straw rope so as not to shake the pot soil attached to the root. However, the selling points of large and medium trees used for garden trees are tree shape and roots. No matter how good the tree shape is,
Those with poor root survival after transportation and transplantation from the production area to the consumption area have zero commercial value. Therefore, this work is extremely important, so that the pot soil attached to the root with a straw rope is uniformly and firmly wound so that it does not collapse during transportation. However, when the straw is wound, if there is a convenient thick root, the straw rope can be wound with the support as a support, but if not, the straw is wound into the pot soil attached to the root as shown in FIG. The potted soil attached to the roots is not the same size for all the plants, but has various sizes and shapes.The soil is also various from sandy to clay, and the potted soil attached to the roots with straw rope is transported. It is very difficult and requires a fairly skilled worker to wind it evenly and firmly so that it does not collapse. In other countries, when the land is frozen like a bedrock, it is cut open with a plow, and the roots and frozen soil are lifted and moved together as a unit. 4), cloth and wire,
Cloth wrapping method to wrap bowl using wire mesh is performed,
It is a rough technique for transplanting, and it is said that the method of rooting in the above-mentioned method in Japan is the best in a method unique to Japan in terms of the root survival rate of planted trees.

[0003]

The method of tying using the above-mentioned rope requires skill and time for surrounding tying, but it has the convenience that the rope can be buried in the soil while being tied. The method of tying linen or sackcloth with a rubber band is very easy at the time of tying, and the tying ability is greatly improved.However, to improve root survival and growth after transplantation,
Since it is desired that the binding of the potting soil that adheres to the roots disintegrates quickly in the soil, it is necessary to remove the rubber band, which is very slow to disintegrate in the soil, at the time of embedding, and there is a problem that handling is troublesome. . Accordingly, it is an object of the present invention to provide a novel pottery tying tool having both the soil disintegration property of a rope or the like and the workability of tying a rubber band or the like, and a rubber composition suitable for use therein.

[0004]

According to the present invention, an elastic tissue used for a tying tool such as a rubber band is made of a foam rubber which does not impair the binding property of the potting soil, and at the same time, the rubber composition itself does not collapse. It was found that the water-soluble additive eluted in the soil dissolved into the soil due to the moisture in the soil and became a foamed state more than the state before being buried in the soil, the tensile strength was reduced, and it was broken. And the rubber composition 9 containing a foaming agent
Not bind the rubber component relative to 7-30 parts by weight, Ri Na was added to and mixed with water soluble additive 3 to 70 parts by weight, eluting with soil,
Acrylic bisamide with biodegradability as vulcanizing agent
It is in the soil disintegrable rubber composition used in combination . The mixing ratio of the rubber composition with the water-soluble additive and the foaming agent is such that the modulus, tensile strength, or elongation of the rubber physical properties that require the minimum necessary binding force to prevent collapse of the potted soil attached to the root during transportation It is determined by a combination of (possible at least two-fold stretching), the root survival rate after transplantation, and the disintegration rate desired for development (disintegration within at least 6 months). Normally, originating
It foams 1-5 parts by weight against the rubber composition 97 to 30 parts by weight was added, preferably added water-soluble additives 3 to 70 parts by weight. In this range, when a large degree of elongation, a high modulus, and a high tensile strength required for binding are required, while increasing the compounding amount of the rubber composition and reducing the compounding amount of the foaming agent, the structure of the foam is avoided. When it is desired to increase the disintegration rate, it is selected to increase the amount of the water-soluble additive, or to use a foaming agent to make the structure of the foam. However, the important point is the collapse of the soil due to the transport of the potted soil, which has the highest value of the potted soil attached to the unity in order to reduce the viability of the planted plant and reduce the root viability after transplanting. Physical properties are required. From this, the structure of the foam tends to have relatively low physical properties such as modulus, tensile strength, and elongation.To prevent collapse of the potted soil due to the transport of potted soil, ensure that the specified rubber properties can be secured. It is necessary to keep in mind.

[0005]

According to the present invention, the matrix of the vulcanized rubber component constituting the elastic body has a foamed structure, the disintegration in soil is faster than that of the non-foamed structure, and the water-soluble additive binds to the rubber component. Since the water-soluble additive is buried in the soil, the water-soluble additive elutes from the elastic body due to the soil moisture, and the foam has a foamed structure that is higher than the state before embedding the elastic body in the soil. Since this elastic body is stretched and stretched to create a binding force for surrounding and binding the potted soil attached to the root, the tensile strength is significantly reduced due to the foaming state more than the state before embedding in the soil. This leads to splitting.

In order to promote the cleavage of the elastic body in a tensile state, it is preferable that the rubber component also has biodegradability in the soil, and natural rubber having a polyisoprene structure and synthetic natural rubber are used as the rubber component. Is preferred. Incidentally, the main components of natural rubber are rubber hydrocarbons, proteins, fatty acids, sugars and ash. In the soil,
It contains a small amount of oxygen that oxidizes and decomposes the rubber component, and fungi, actinomycetes, and bacteria that decompose organic substances are active, and the rubber component contains water, temperature, PH, oxygen content, etc. Decomposes, albeit at different speeds, depending on the type of organic matter. As the natural rubber and the synthetic natural rubber having a polyisoprene structure as a rubber component, a solid, powder, or liquid polymer having a different polymer shape by vulcanization or molding can be used. As a method for vulcanizing the rubber composition, steam, electric heat, hot water, hot air, salt bath, radiation, or electromagnetic waves may be applied. As a method for molding the rubber composition, extrusion, dipping, mold, and rolling methods may be applied. Further, it is preferable that acrylic bisamide having biodegradability is used in combination as a vulcanizing agent as a vulcanizing agent to promote the collapse of the crosslinked structure of the rubber matrix in the soil. Further, it is also possible to add and mix a soil conditioner to increase the decomposability of the rubber component. As this soil conditioner, for example, a soil conditioner containing thiobacillus, a bacterium that oxidizes sulfur, which has the ability to degrade organic substances, may be used in combination. This can promote the collapse of the crosslinked structure of the rubber matrix crosslinked using sulfur. It is also possible to use a mixture of a soil conditioner containing Thomas, Urea, Trichoderma, Cellulose-decomposing, Kofuna, and Mushroom bacteria, which has an action of decomposing organic substances. or,
It is also possible to mix and use a water-absorbing resin used as a soil conditioner.

The water-soluble additive may be any water-soluble substance that does not bind to the rubber component, but is preferably one that does not harm the transplanted seedlings and planted plants. A nitrogen-based water-soluble fertilizer, a phosphate-based water-soluble fertilizer, and a potassium-based water-soluble fertilizer that improve the rate or promote growth are most preferred. As the water-soluble additive, carboxymethyl cellulose, casein starch,
One or more selected from the group consisting of lecithin, a coagulant, a nitrogen-based water-soluble fertilizer, a phosphate-based water-soluble fertilizer, and a potassium-based water-soluble fertilizer are used. Lecithin naturally exists in important organs of animals and plants and plays a pivotal role in vital phenomena.It is abundantly contained in egg yolk, animal brain pulp, soybean seeds, etc. It is industrially extracted on a large scale. Further, as a coagulant, Diaclear (trade name) manufactured by Mitsubishi Kasei Co., Ltd. , which is a water-soluble polymer obtained by linearly polymerizing acrylamide, can be used. Such coagulants are used in industrial water treatment and municipal sewage treatment. As the nitrogen-based water-soluble fertilizer, ammonium sulfate, salt ammonium, Chile saltpeter, ammonium nitrate, urea, lime nitrogen, lime nitrate and the like can be used. Phosphoric acid-based water-soluble fertilizers include monoammonium dihydrogen phosphate, calcium dihydrogen phosphate, perrinsan lime,
Heavy linsan lime can be used. Potassium-based water-soluble fertilizers include potassium sulfate, potassium chloride, potassium sulfate, caustic acid, plant ash, and compost.

As the above-mentioned foaming agent, it is preferable to use a foaming agent capable of forming open cells, and specific examples thereof include sodium bicarbonate. As the foaming method, the usual vulcanization method described above may be employed.

Using the above rubber composition, pottery tying tools for potted soil adhered to various roots are manufactured. First, for seedlings, the rubber composition has a polyisoprene structure and has a rubber composition containing 97 to 30 parts by weight of a foaming agent. Water-soluble additives 3 to 7 that do not bind to components and elute in the soil

Potted soil tie foam rubber bands that adhere to the roots for plant transplants are preferred.

In addition, the potting soil attached to the roots has various shapes, the soils are various, and the thick roots are used as supports, so that they can be wound. The unity force is also easy to apply. In addition, since the production cost is low, the straw rope for large and medium trees has a polyisoprene structure, and does not bond with the rubber component to 97 to 30 parts by weight of the rubber composition containing a foaming agent. A mixture comprising a soil-disintegrable rubber composition obtained by adding and mixing 3 to 70 parts by weight of a water-soluble additive eluted in a tape, extruding a tape, vulcanizing and cutting, and then producing a wall thickness of 0.5 to 60.0
