Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a bark mulching material for use in a greening business or agriculture.

[0002]

2. Description of the Related Art Conventionally, a mulching material is usually laid between trees and plants to suppress weeds and prevent water evaporation. It is preferable that the mulching material does not scatter or run off, but a bark mulching material has attracted attention as a suitable material. JP-A-2-186922,
JP-A-6-133652 proposes a method for producing this bark mulching material.
The bark is finely crushed, and an asphalt emulsion and a sizing material are added to the crushed bark to impart coloring and caking properties. A gluing material is added to the bark to impart caking properties.

[0003]

However, since the mulching material of the preceding example contains a mixture of fibrous, massive, and powdery materials, there are few gaps as a whole, Since bark that is easily clogged and that has been left outdoors for a long period of time is used, the bark is easily decomposed and turned into fertilizer, and after laying, weeds may grow. In addition, there is a material mixed with vegetation paste material that exerts caking power when moisture escapes, but because the moisture is in the bag, the bark corrodes and if not used immediately, moisture will The loose vegetation glue exerts caking power and becomes hard to lay.
In particular, those containing asphalt emulsion, especially when dried, are easily ignited easily, and often cause fires by cigarettes of automobiles, pedestrians, etc., which not only impairs the effect as a mulching material, but also causes damage to trees and trees. The damage of the flower was remarkable.

The present invention has been made to solve such problems. In short, the bark of coniferous or hardwood is crushed and used as a mulching material as fibrous bark pieces to prevent scattering and runoff. A mulching material that is difficult to burn is manufactured.

[0005]

SUMMARY OF THE INVENTION Under the above-mentioned problems, the present invention relates to a polymer absorbing material which exerts a cohesive force when water is absorbed by crushing the bark of softwood and hardwood as fibrous bark pieces. It is characterized by incorporating a body polymer.

The present invention also provides a powdery refractory as a fibrous bark piece by pulverizing the bark of coniferous and hardwood trees together with a high molecular weight absorbent polymer that exhibits a cohesive force when absorbing moisture. It is characterized in that it is mixed with the entire fibrous bark piece to make it difficult to burn.

[0007]

The bark of softwoods and hardwoods is pulverized, and as a fibrous bark piece, a high molecular weight absorbent polymer which exerts a cohesive force when absorbing moisture is mixed together with a powdery refractory. After laying, the polymer exhibits a cohesive force when water is applied or when it rains, and when moisture evaporates from the mulching material, the whole is solidified in a plate shape to prevent scattering and runoff, Since the powdered refractory is mixed with the bark pieces and the high-absorbent polymer, fire is prevented, the bark pieces do not become fertilizer, and weed vegetation is suppressed.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below. The bark of softwood and hardwood is crushed by a high-performance crusher. In addition, it is preferable to use domestically produced products which are free from concern about salt damage and the like.

The raw materials are dried and put in a fixed amount in a stock yard, and a high molecular weight absorbent polymer is uniformly mixed into the stock yard with an appropriate ratio using a wheel loader or the like. The reason is that if a binding force is exerted before construction, the whole will be solidified and difficult to handle, and a material that exhibits a binding force when absorbing moisture after the construction is suitable. For this purpose, the properties of the high molecular weight absorbent polymer are the easiest to handle, but other hydrocolloid materials may be used as long as they have the same effect. Examples of the high molecular weight absorbent polymer include tachyfloc of Taki Kagaku, hydrolyzed starch polyacrylonitrile copolymer H-span, and graft copolymer. In general, the polymeric polymeric material useful in the articles of the present invention may be organic or inorganic, is physiologically harmless (non-toxic), swells in the presence of moisture, and is relatively hydrophilic. . The high molecular weight absorbent polymer material is preferably used in the form of fine particles such as powder, granules and flakes. In addition, the powdery diatomaceous earth is mixed with a wheel loader or the like at an appropriate ratio so that the high-molecular-weight absorbent polymer is mixed uniformly and simultaneously the powdery diatomaceous earth is mixed uniformly with the entire fibrous bark piece. In place of diatomaceous earth, other refractories having the same effect as powdered and granular, flaky ceramics, perlite, vermioculite, cristopalite, etc. It may be a thing. Each of the mulching materials thus produced is sealed in a bag with a bagging machine.

In the method of laying the mulching material described above, the mulching material is laid at a place of laying with a thickness of 3 cm to 5 cm. If water is moderately absorbed, the high molecular weight absorbent polymer absorbs water and expands, and exhibits adhesiveness to bond the whole, and when the water evaporates, the whole becomes plate-like and solidifies. In addition, it prevents scattering, runoff, and fire is difficult to fire because powdered refractories are uniformly mixed into the entire fibrous bark piece and consolidated. In addition, since the bark in the bag is dry, it does not easily rot, is extremely long-term fertilizer, is excellent in suppressing the vegetation of weeds, is easy to handle, and has the advantages of good appearance.

[00011]

As described above, since the present invention has been described above, a mulching material which does not easily cause scattering, runoff and clogging and which does not burn easily can be produced simply and inexpensively. Among the barks, conifers are guaiacyl-type lignins composed of coniferyl alcohol units, and have strong absorption of ultraviolet rays, and are resistant to ultraviolet rays, steam, and acidic alkali. In addition, lignin is hardly decomposed and is unlikely to become an enzymatic saccharified material, so that its effect can be maintained for a long time.
