Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a herbicide for imparting a unique color tone, scent and the like to the grass used for tatami mats and the like.

[0002]

BACKGROUND OF THE INVENTION Generally, rushes used for tatami mats and the like are soaked in a liquid in which soil called so-called dyed soil is suspended in water immediately after harvesting, so as to carry out mud dyeing. By drying it, the color tone and scent peculiar to rush are retained, and the water content during storage is adjusted. As the dyed soil, natural dyed soil such as Awaji dyed soil and Fukuoka dyed soil is used, but since it is a natural product, it is difficult to stably supply dyed soil of uniform quality.

Further, since a large amount of natural dyed soil is used for mud dyeing, a large amount of dust is generated during the drying, storage, warehousing, and fiber making of rush, which deteriorates the working environment. Further, the natural dyed soil alone has insufficient adhesion to the rush and color tone, and there is a problem in terms of quality. Therefore, various synthetic dyes have been developed to replace natural dyes. For example, those containing goethite, magnetite, titanium oxide, calcium carbonate or the like as a main component (JP-A-49-36911); those containing an organic polymer substance dispersion or emulsion as an essential component (JP-A-50- 4313); containing titanium oxide containing 20% or less of iron as the main component (JP-A-48-99409); particle diameter 0.044 m.
Water-soluble dye adhered to the surface of mineral coarse particles having a grain size composition occupying 90% or more in the range of m to 3 mm (JP-A-5-9397); titanium oxide, acid clay, and surfactant as main components (Tokukaihei 2-28266); Titanium oxide, jammon rock powder and powdery surfactant as main components (Tokukaisho 62-246703); Fine-powdered titanium oxide, alkaline earth Those containing carbonates or sulfates of similar metals, color pigments and dyes as main components (Japanese Patent Publication No. 52-139); those containing dyes, colored pigments, titanium oxide, lignin sulfonic acid or salts thereof as main components (JP-A-4-128003): Dye, yellow iron oxide, copper phthalocyanine blue, copper phthalocyanine, titanium oxide, lignin sulfonic acid or a salt thereof as a main component (JP-A-3-18) 505 JP), and the like.

However, all of these treatment agents are used by being mixed with natural dyed soil, and since the amount of natural dyed soil used is still large, the problem of dust has not been solved. Further, even when the above-mentioned synthetic soil was used in combination, the adhesion to the rush was not sufficient, and it was insufficient to impart the color tone, scent and texture peculiar to the rush. A main object of the present invention is to solve the above technical problems and to provide a herbicide for treating natural dyes.

Another object of the present invention is to provide a herbicidal agent which has improved adhesion to grass, retains the scent and texture peculiar to grass, and has an excellent color tone and is not capable of grass treatment.

[0006]

[Means and Actions for Solving the Problems] As a result of earnest studies to achieve the above-mentioned problems, the present inventors have found that (1)
Synthetic dyes composed mainly of titanium oxide and zeolite have excellent performance. (2) By using a surfactant together, the dispersibility of natural dyes and synthetic dyes on rush is improved. The inventors have found a new fact that the adhesion to rush is improved, and completed the present invention.

That is, the rush treatment agent of the present invention is characterized in that 0.1 to 30 parts by weight of zeolite and 0 to 5 parts by weight of a surfactant are mixed with 100 parts by weight of titanium oxide. By using the rush treatment agent of the present invention, it is possible to significantly reduce the amount of the natural dye used in combination with the synthetic dye, and to obtain a foliage having a good color tone while maintaining the fragrance and texture peculiar to rush. it can.

The rush treatment agent of the present invention has a grazing area of 10
Although 8 to 20 kg is used per a, the amount of the natural dye used in combination can be reduced from 600 kg in the related art to 480 to 120 kg. Therefore, the amount of dust is reduced, which is preferable in terms of resource saving. The titanium oxide used in the present invention is not particularly limited and may be either anatase type or rutile type. The particle size of titanium oxide is also not particularly limited, and is generally commercially available with a particle size of 0.1 to 0.1.
Those having a thickness of 0.3 μm can be preferably used.

The zeolite may be either natural zeolite or synthetic zeolite, but it is desirable to use synthetic zeolite in terms of quality uniformity and economical efficiency. There are various types of synthetic zeolite,
In the present invention, the rational formula M ₂ O.Al ₂ O ₃
2SiO ₂ · 4.5H (where, M is Na or K) ₂ O preferably used crystalline aluminosilicate represented by.

Such a zeolite generally has an ion-exchange ability, and captures hardness components (Ca ²⁺ , Mg ^2+, etc.) eluted from the natural dye soil used in the rush treatment to disperse the natural dye soil. -It is considered that it not only promotes suspension but also maintains the dispersion of titanium oxide, which is the main component, and promotes deposition on rush. Since zeolite has no solubility in water, the particle size is preferably fine, and is about 10 μm or less, preferably 1 to 2 μm.

The amount of zeolite used is 0.1 to 30 parts by weight, preferably 1 to 10 parts by weight based on 100 parts by weight of titanium oxide.
Parts by weight. If the amount of the zeolite used is less than 0.1 part by weight, the dispersion / suspension of the natural dye and the synthetic dye will be deteriorated, resulting in poor adhesion to the grass and uneven coloring. On the other hand, when the amount of the zeolite used exceeds 30 parts by weight, a phenomenon occurs in which the synthetic and natural soil rush does not deposit on the grass and flows down.

The surfactant used in combination with zeolite includes at least one selected from sodium tripolyphosphate, sodium polyacrylate-based surfactant and sorbitan nonionic surfactant. The sodium tripolyphosphate is not particularly limited, and any commercially available sodium tripolyphosphate may be used. In addition, although the characteristics of the sodium polyacrylate-based surfactant vary slightly depending on the average degree of polymerization, any one may be used in the present invention. As the sorbitan nonionic surfactant, it is preferable to use a polyoxyethylene sorbitan ester having an HLB of 8 or more.

All of these surfactants are water-soluble and play a role of assisting the dispersing / suspending action of zeolite. The amount of the surfactant used is 0 to 5 parts by weight, preferably 0.
It is from 05 to 1 part by weight. When the amount of the surfactant used is more than 5 parts by weight, the cleaning action of the surfactant becomes large, and a phenomenon occurs in which synthetic and natural dye soil does not adhere to the grass and flows down, which is not preferable.

In the present invention, the surfactant is not always a necessary component, but by using the surfactant, an aqueous solution of the surfactant to be described later is prepared, particularly when the rush is dyed in a desired color tone. There is an advantage that the coloring agent can be easily dispersed in this aqueous solution at the step of. The colorant is not particularly limited, and examples thereof include green pigments such as copper phthalocyanine green pigments and C.I.
I. Blue dyes such as Basic Blue 3 dye can be mentioned.

The surfactant may be added to the treatment agent as it is, but in order to improve the dispersibility of the colorant, the adhesion to the grass and the color tone of the grass, the treatment agent in the form of powder is used. It is preferable to mix them. To obtain a powdered surfactant,
First, an aqueous solution of a surfactant having a predetermined concentration is prepared, and then white carbon is added and agitated to form a powder. that time,
When a colorant is used, the required amount of it is dissolved in an aqueous solution of a surfactant. The amount of white carbon added is appropriately 10 to 210 parts by weight, preferably 20 to 100 parts by weight, based on 100 parts by weight of the aqueous surfactant solution. The particle size of the obtained powdery surfactant is not particularly limited, but it is usually preferable to adjust it to about 10 to 1000 μm.

The powdery surfactant thus obtained is mixed with a predetermined amount of titanium oxide and zeolite and, if necessary, pulverized,
The rush treatment agent of the present invention is obtained. When treating grass using the rush treatment agent of the present invention, the rush treatment agent of the present invention may be used alone by suspending it in water, but it is usually used by mixing with natural dyeing soil. Preferably. Specifically, water 15
A mixture of 120 to 480 parts by weight of natural dye and 5 to 50 parts by weight of the agent for treating grass of the present invention is mixed with 00 parts by weight to prepare a dispersion for treating grass. The grass treatment may be carried out according to a conventional method. Immersion of fresh grass immediately after harvest in the above-mentioned dispersion liquid for grass treatment is performed by mud dyeing, then withdrawn from the dispersion liquid and dried in the sun. Immersion time of the rush is usually about 30 seconds to 20 minutes at room temperature. Further, it is appropriate to use the dispersion liquid for vegetation in an amount of about 4 to 6 times the immersion weight of the vegetation. In this way, a rush having a unique color tone and scent without uneven color is obtained.
