Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

 The present invention relates to a metal polishing material.

[Prior art]

When a blade is used, the blade is chipped or the blade edge is turned back, resulting in poor sharpness. Therefore, in such a case, it is necessary to sharpen again with a grindstone or the like. By the way, when the blade is chipped, it must first be roughened with a rough whetstone so that the chipped part is almost flush with the other parts, and then finished with a finishing whetstone.
The grinding operation must be performed in earnest, but if the blade is turned back, it only needs to be slightly applied to the finishing whetstone.

[Problems to be solved by the invention]

However, the grindstone is relatively heavy, and in general households, it is often said that it is troublesome to take out and grind the grindstone with the turning of the blade edge, and even if the sharpness becomes poor, the grindstone is used as it is. Also, in the case of a blade having a curved surface, such as a haircut clip, it is very difficult for an amateur to sharpen with a grindstone. In view of such circumstances, the present invention is lightweight and
It is an object of the present invention to provide a metal polishing material that can easily polish a metal material such as any cutting tool.

[Means for Solving the Problems]

In order to achieve such an object, the present invention provides a flexible, elastic, open-cell resin foam having at least a surface layer of at least a surface oil of silicone oil 1000 cc, and stearic acid or a salt thereof in an amount of 100 to 200 g. , And 3000
The gist is a metal polishing material impregnated with a mixture containing 50 to 100 g of a polishing material having a mesh or less.

[Action]

According to the above configuration, when the polished surface of the desired metal material is pressed against the metal polished material, the thin plate material is deformed along the polished surface of the metal material. Then, when the sliding contact is made in this state, dirt adhering to the surface of the metal material and, for example, a return formed on the cutting edge are removed neatly. In addition, the lubricant adheres to the surface of the metal material to protect the surface of the metal material and imparts gloss.

【Example】

Hereinafter, the present invention will be described in detail with reference to the drawings showing the embodiments. FIG. 1 is a cross-sectional view of one embodiment of a metal polishing material according to the present invention as viewed from the side, and FIG. It shows. As shown in the figure, the metal polishing material 1 is provided with a sheet-shaped base material 11 and, on one side thereof, a polishing layer 12 formed by fixing a mixture of abrasive particles of 3000 mesh or less dispersed and mixed in a lubricant. Are formed. Also, on the other side of the base material 11,
A release sheet is adhered via an adhesive layer 13. As the base material 11, a lightweight, flexible and elastic open-cell synthetic resin foam is used. Examples of the synthetic resin forming the foam include polyurethane resin, polyester resin, polystyrene resin, and polyethylene resin. The abrasive particles are not particularly limited, but include alumina,
Particles such as artificial abrasives such as carborundum, boron carbide, and other high-hardness carbides, and natural abrasives such as emery, spinel, garnet, and silica sand are included. As a lubricant, a mixture of silicone oil and stearic acid or a salt thereof is used. The mixing ratio of abrasive particles and lubricant is 1000 for silicone oil.
Preferably, the proportion of cc, stearic acid or a salt thereof is about 100 to 200 g, and the abrasive particles are about 50 to 100 g. Since the base material 11 is an open-cell foamed resin, the mixture can be fixed by impregnation by a vacuum impregnation method. The metal polishing material 1 of this embodiment is as described above, and is lightweight and easy to handle. In addition, since it is flexible, even if the cutting edge is curved, it is deformed along the surface, so that anyone can sharpen easily. Moreover, it can be cut into a desired shape and used, and the release sheet 14
If it is peeled off and adhered to a flat surface with an adhesive, it can be used like a conventional grindstone. Further, the lubricant has the effect of shining the blade and preventing rust. In order to remove the return of the cutting edge of the scissors 8, if the blade is pressed against the polishing material 1 as shown in FIG. . FIG. 3 shows a second embodiment of the metal polishing material according to the present invention as viewed obliquely from above. As shown in the figure, this metal polishing material 2 does not have the adhesive layer 13 and the release sheet 14 of the first embodiment, but has a flat core material 21.
A foamed resin substrate 23 having a polishing layer 22 made of a mixture of abrasive particles and a lubricant fixed on both surfaces thereof is laminated on, for example, as shown in FIG. Dirt can be removed. When used as a stain remover, it is preferable to reduce the amount of abrasive particles. When the amount of the abrasive particles is reduced, the metal polishing material 2 can be used as a lens for polishing eyeglasses. The metal polishing material according to the present invention is not limited to the above embodiment. For example, in the first embodiment, the polishing layer 12 made of abrasive particles or the like is formed on one surface of the base material 11 and the adhesive layer 13 is formed on the other surface. It does not matter.

【The invention's effect】

As described above, the metal polish according to the present invention is, as described above, at least a surface layer of a base material made of an open-cell resin foam having elasticity, silicone oil 1000 cc, stearic acid or a salt thereof is 100 to 200 g. , And 3000
Since the mixture containing 50 to 100 g of the abrasive below the mesh is impregnated, it is lightweight and can easily grind any metal material such as a knife.
