Abstract

PURPOSE:To reduce the dropout of abrasive material and permit to use the abrasive material for a long period of time by a method wherein a low melting point metal is solved and sprayed onto the surface of a sheet-like base material having flexibility to form the film of coating and, them, the abrasive material is sprayed on the film to form an abrasive layer. CONSTITUTION:The low melting point metal, such as zinc or the like, is sprayed by an arc spraying method or a flame spraying method onto the surface of the sheet-like base material 1 having flexibility, such as craft paper, cotton cloth or the like, to form the film of coating 2. Next, a metal such as stainless steel, ceramic, thermet or the like, which is constituting the grinding material, is sprayed onto the film 2 by a plasma spraying method or the like to form the abrasive layer 3 and sandblasting is applied onto the surface thereof to obtain a desired roughness of the surface. According to this method, the dropout of the abrasive material may be reduced and the sheet may be used for a long period of time. The abrasive material may be selected arbitrarily in accordance with the use of the abrasive sheet and granular abrasive material is not used, therefore. The manufacture thereof may be facilitated and the abrasive layer may be renewed by the sandblasting.

Description

[Detailed description of the invention] The present invention relates to a method for producing a sheet-like abrasive material.

Sand vapor is used as a conventional sheet-like polishing tool, but the abrasive particles tend to fall off from the base paper and MA is easily damaged, so it is not durable or durable.
It has the disadvantage that it has poor properties, and there is also a problem that there is a limit to the number of months that E-1 polishing particles can be produced.

The present invention provides a new sheet abrasive material that solves the above problems. 1] The purpose is to provide a method for fabricating a flexible sheet-like base material, in which a low contact point metal is applied to the exposed surface i of a flexible sheet-like base material to form a corrugated bottom, and then, There is also U)-C, which is characterized by the sound sequence I,..., and c: If iu)-a, which forms the note sequence.

Any of the arc spraying method, flame spraying method, and plasma spraying method may be used for the spraying of the polishing cables, and it is also possible to use an arc spraying method, a flame spraying method, or a plasma spraying method. It is best to adjust it to

In the present invention, it is not necessary to obtain a sheet-like abrasive material by the above method, but it is also possible to obtain abrasive material in the form of a sheet. : Scraps (31
Blasting may be applied to the 0-surface tune to obtain the desired surface roughness.

Since the present invention has the above configuration, it has the following effects.

■ The low-melting point metal coating formed on the sheet-like substrate and the grinding M layer made of Ishi 1 rejuvenation material formed on this IM are both formed by thermal spraying, so
The bond between the coating and the senryu layer is strong, the 111F abrasive material is less likely to fall off, and it can withstand illegal use.

■ The material for the abrasive layer of the 411F coating layer can be selected at will as long as it can be thermally sprayed. For example, in order to obtain a sheet-like 1 degree polishing of a bronze surface, 4i) 1
Bronze can be adopted as a B series. In this manner, by selecting the abrasive layer level to 0, it is possible to easily produce a sheet-like abrasive material that can be used in a variety of ways.

In addition, if you choose a ceramic material for the abrasive thread that is resistant to wear and tear, it will be easier to use than conventional sandpaper (

The hexacuracy can be made as above in jlQ: k:iW manner.

■ Unlike conventional sand vapors, which use particulate material, we use non-particulate materials such as stainless steel, which are made into moderate grains during revision.
Since the Q1 stratum can be formed, the sheet-like abrasive material can be manufactured easily.

■ The bond between the Ken JM layer, the coating, and the sheet-like base material is ■
As mentioned above, since it is strong, the polishing layer can be regenerated by blasting.
