Abstract

The present invention relates to a polishing wheel in which a long fiber nonwoven fabric is bonded by thermosetting epoxy resin to a sandpaper combination formed by overlapping sandpaper.

The polishing wheel according to the present invention is a polishing wheel in which the hub wheel 30 is mounted on a sandpaper assembly 20 in which a plurality of sandpapers 10 are circumferentially superimposed on the upper surface of the sandpaper assembly 20. The disk-shaped long fiber nonwoven fabric 40 in which the hollow part 41 is formed is joined by the thermosetting epoxy resin 50, It is characterized by the above-mentioned.

Description

Polishing Wheel {SANDPAPER WHEEL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing wheel, and more particularly, to a polishing wheel in which a disc-shaped long fiber nonwoven fabric is bonded by a thermosetting epoxy resin to a sandpaper assembly formed by overlapping sandpaper.

"Polishing wheel" is introduced in Korean Utility Model Registration No. 20-0396161 (registered on June 3, 2005).

The polishing wheel relates to a polishing wheel attached so that the sandpaper is radially overlapped with each other, and the sandpaper is formed in a donut shape having a hollow body by overlapping a plurality of sandpapers composed of a rectangular body and an adhesive part integrally formed on an upper end of the body. The circular mounting portion is formed by a plurality of overlapping adhesive parts, and the circular polishing part is formed by the body part, and when the hub wheel is mounted on the circular mounting part, the upper cap and the lower cap of the hub wheel are joined by an epoxy resin adhesive. It is characterized by.

However, the conventional polishing wheel as described above has the disadvantage that the sandpaper is easily separated from the sandpaper combination by the frictional heat during polishing, and is broken, thereby shortening the service life.

Accordingly, it is an object of the present invention to provide a polishing wheel having a long-life, which has a long service life, and is improved in structural performance and work performance by joining a disk-like long fiber nonwoven fabric with a thermosetting epoxy resin to a sandpaper assembly formed by overlapping sandpaper. .

One example of the polishing wheel according to the present invention for achieving the above object is a polishing wheel in which a hub wheel is mounted on a sandpaper assembly in which a plurality of sandpapers are circumferentially overlapped, a circle having a hollow portion formed on an upper surface of the sandpaper assembly. It is characterized in that the long filament nonwoven fabric is bonded by a thermosetting epoxy resin.

As a result, the abrasive wheel according to the present invention has a disk-like long fiber nonwoven fabric bonded to the upper surface of the sandpaper assembly by thermosetting epoxy resin, so that it does not adhere to the surface of the workpiece, and has a long service life and strength of the sandpaper assembly. Has the effect of improving.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 to 3, in the polishing wheel according to the embodiment of the present invention, the hub wheel 30 is mounted on the sandpaper assembly 20 in which the sandpaper 10 is circumferentially overlapped. In addition, the abrasive wheel is a disk-like long-fiber nonwoven fabric 40 having a hollow portion 41 formed on the upper surface of the sandpaper assembly 20 is bonded by a thermosetting epoxy resin (50; see FIG. 2).

The long fiber nonwoven fabric 40 is adhered to the upper portion of the sandpaper assembly 20 to improve structural strength, and also has excellent adhesiveness and tensile strength to prevent damage to the sandpaper assembly 20, and there is no harm to the human body.

The thermosetting epoxy resin 50 is not only prevented from melting during the polishing operation and buried on the surface of the workpiece, but also has high heat resistance and good wear resistance.

Polishing wheel according to the present invention configured as described above by the thermosetting epoxy resin 50 and the long fiber nonwoven fabric 40, as shown in Figure 4, the sandpaper 10 in the polishing process in the original state shown by the two-dot chain line It can be worn down to the extent that it can be used as shown by a solid line to increase its service life, and increase its hardness to prevent the sandpaper from flipping back when polishing the floor or curved surface. In addition, as described above, due to the properties of the thermosetting epoxy resin 50 does not bury the surface of the workpiece, there is an advantage that is harmless to the operator due to the nature of the long fiber nonwoven fabric (40).
