SUMMARY OF THE INVENTION The invention made to solve the above-mentioned problems is to cut a rust preventive sheet having a rust preventive function.
And / or ground containing fine multiple rust body formed
It is also a rust preventive material placed inside the package . According to the rust preventive material, since the rust preventive body obtained by cutting and / or crushing the rust preventive sheet has a rust preventive function, the inclusion of the rust preventive material inside the package causes rust in the packaged object. Can be prevented. In addition, since the rust preventive material is composed of a plurality of rust preventive bodies obtained by cutting and / or crushing the rust preventive sheet , it can be put in a narrow part such as a gap of a packaged object apart from the rust preventive sheet. The rust preventive action can be exerted even on a portion where the rust preventive sheet is not close.

As the above-mentioned rust preventive body, it is preferable to use one or more kinds selected from the group consisting of a long strip-shaped strip, a fine strip-shaped strip and a pulverized granular strip. By using one kind or two or more kinds of rust preventive bodies having different shapes in this way, the rust preventive properties of the rust preventive material can be adjusted.

As the rust preventive sheet, it is preferable to use a non-woven fabric or paper material impregnated with or coated with a rust preventive agent. Since the non-woven fabric or paper material is used as described above, it is easy to impregnate or apply the rust preventive, and it is easy to cut or crush the rust preventive body.

Examples of the rust preventive agent include nitrites, fatty acid salts, benzoates, carbonates, heterocyclic compounds, and the like.
It is preferable to use one selected from the group consisting of these combinations . These rust preventive agents have advantages such as excellent volatility and large rust preventive action.

The rust preventive material has breathability and

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 2 is a schematic diagram showing a rust preventive material according to an embodiment of the present invention, and FIGS. 1A to 1C are schematic diagrams showing a rust preventive body used for the rust preventive material of FIG. The rust preventive material 1 in FIG. 2 is composed of a container 2 and a rust preventer 3 housed in the container 2.

The housing 2 is housed so that the fine rust preventive body 3 is not scattered, and is breathable so as not to block the rust preventive function of the rust preventive body 3. The form of the storage body 2 can be various forms such as a bag and a box. When the storage body 2 is made into a bag, the rustproof material 3 described later is formed from a soft rustproof sheet, so that the rustproof material 1 can be freely deformed, and can be packed in gaps of various shapes. The rust preventive effect can be exerted even in a gap or the like where the rust preventive agent is unlikely to enter. As the material used for the storage body 2, a breathable paper material such as Japanese paper, a cloth material, and a synthetic resin sheet material in which a large number of small vent holes are formed can be applied. Of these, Japanese paper is preferable in consideration of strength, air permeability, moldability, recyclability and the like. further,
By using the same kind of material as the rust preventive body 3 described later for the material of the container 2, the rust preventive material 1 can be more easily recycled.

The rust preventive body 3 is formed by cutting and crushing a rust preventive sheet having a rust preventive function, and its shape and size are not limited. However, as the rust preventive body 3, as shown in FIG.
A strip-shaped rust preventive body 3a obtained by cutting a rust preventive sheet as shown in (a) into an elongated shape, a strip rust preventive body 3b obtained by finely cutting as shown in FIG. 1 (b), and FIG. It is advisable to use three types of granular rust preventive body 3c obtained by crushing a rust preventive sheet as shown in (4), and to use one kind or a mixture of two or more kinds of them.

Since the rust preventive body 3c has the maximum specific surface area, the rust preventive agent has a high volatility and has an immediate effect on the rust preventive effect. On the other hand, since the rust preventive body 3a has the smallest specific surface area,
The anti-corrosion agent has low volatility and is not immediately effective for anti-corrosion, but on the contrary, it has a long life. Since the rust preventive body 3b has a specific surface area between those of the rust preventive body 3a and the rust preventive body 3c, the rust preventive function has an intermediate property between the two.

Therefore, the above-mentioned rust preventive bodies 3a, 3b and 3c
Of these, by using one kind or a mixture of two or more kinds, the rust preventive properties of the rust preventive material 1 can be arbitrarily adjusted. Further, by mixing and using the above-mentioned rust preventive bodies 3a, 3b and 3c, it is possible to achieve a balance between immediate effect and service life, and to exhibit a constant rust preventive effect for a relatively long time.

The size of the rust preventive body 3 may be appropriately adjusted depending on the shape of the object to be packaged, the rust preventive effect of the rust preventive sheet, etc. The size of the rust preventive body 3a is about 3 to 20 mm in width. The length of the rust preventive body 3b is about 4 to 20 mm in length and width, and the average size of the rust preventive body 3c is about 1 to 3 mm. By setting the size to this extent, the difference in the above-mentioned rust prevention characteristics becomes remarkable.

The rust preventive sheet forming the rust preventive bodies 3a, 3b and 3c is not particularly limited as long as it is a sheet having a rust preventive function, and various kinds can be used. However, in general, a paper material or a cloth material impregnated with or coated with a vaporizable rust preventive is used.

As the paper material used for the rust preventive body 3, for example, high-quality paper, medium-quality paper, bleached kraft paper, unbleached kraft paper, unbleached kraft paper, liner paper, paper core paper kraft paper, etc. are used. be able to. Neutral kraft paper is preferable from the viewpoint of the amount of rust preventive impregnated, the strength, the degree of influence on the article to be packaged, and the like. The weight of the paper material used for the rust preventive body 3 is not particularly limited, and is, for example, 30 g / m ² or more 3
It is used by appropriately selecting from the range of 00 g / m ² or less according to the purpose of use.

The cloth material used for the rust preventive body 3 is not particularly limited, but a nonwoven fabric is preferable in consideration of the impregnated amount of the rust preventive agent and the like. In addition, examples of the material of the cloth material used for the rust preventive body 3 include polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), nylon and the like in consideration of water resistance and the like. Further, the basis weight of the nonwoven fabric layer is preferably about 30 to 80 g / m ² in consideration of strength, the amount of the rust preventive impregnated and the like.

The rust preventive agent is not particularly limited, and a general one can be used. In particular, in order to prevent corrosion of ferrous metal materials, a group consisting of nitrite, fatty acid salt, benzoate, and a combination thereof is used .
It is preferable to use one selected from loops , and for rust prevention of nonferrous metal materials, one selected from the group consisting of fatty acid salts, benzoates, carbonates, heterocyclic compounds, and combinations thereof. Should be used.

The coating amount of the rust preventive agent is preferably 8 g / m ² or more and 30 g / m ² or less in terms of solid content, and 10 g
/ M ² or more and 15 g / m ² or less are particularly preferable. This is because when the coating amount is less than the above range, the rust preventive effect becomes insufficient, and conversely, when the coating amount exceeds the above range, the surface of the rust preventive body 3 becomes sticky or rust preventive. This is because the agent crystallizes.

The rust preventive material of the present invention is not limited to the above embodiment. For example, the storage body 2 is not used,
It is possible to use only the rust preventive body 3.

[0024]

As described above, according to the rust preventive material of the present invention, for example, by placing the rust preventive material inside a package in which a metal product or the like is packaged, the rust preventive sheet separated from the rust preventive sheet can be obtained.
The rust preventive function can be exerted throughout the entire package such as a narrow gap in the package. Further, the rust preventive material acts as a cushion and can also exert a cushioning effect.
