Abstract

The present invention relates to an abrasive disk that is excellent in workability and stability and has a low degree of fatigue applied to workers and tools, and a process for producing the same. The abrasive disc is excellent in stability by virtue of a high adhesive strength of each layer, has high flexibility, elasticity, and adhesiveness, and is lightweight per unit area. Thus, it has a low degree of fatigue applied to workers and expensive tools. In addition, according to the above production process, the abrasive disk can be continuously mass-produced.

Claim(s)

1 . An abrasive disk, which comprises: a coated abrasive; an interposed layer comprising at least one selected from the group consisting of a hemp fabric layer, a glass fiber fabric layer, and an adhesive layer; and a vulcanized fiber layer.;
15 . A process for producing an abrasive disk, which comprises: (1) laminating a coated abrasive, an interposed material, and a vulcanized fiber, and then pressing, drying, and winding the laminate to prepare a roll-shaped laminate; and (2) unwinding the roll-shaped laminate and cutting it into a predetermined shape to continuously produce a plurality of abrasive discs, wherein the interposed material comprises at least one selected from the group consisting of a hemp fabric, a glass fiber fabric, and an adhesive, and the lamination, pressing, drying, and winding in the above step (1) are carried out in a continuous process.
