Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a coated abrasive paper used for polishing wood surfaces, metal surfaces, plastic surfaces, etc. in the wood industry, metal processing industry, plastic processing industry, etc.

Prior Art This type of conventional coated abrasive paper is
As shown in the enlarged cross-sectional view of the figure, an abrasive layer 2 is provided on one side of the base material 1, and the type of abrasive material, particle size, type of base material, etc., as well as the name of the manufacturing company and brand mark, etc. are displayed. The printed layer 3 provided is applied to the back surface of the other side of the base material 1.

Problems that the invention aims to solve With conventional coated abrasive paper, the user has to turn the coated abrasive paper over and look at the back side in order to check the type of abrasive material, particle size, type of base material, etc. This turned out to be surprisingly troublesome. Furthermore, this is especially troublesome when the coated abrasive paper is used by being attached to the abrasive tool.

Furthermore, the entire surface of the abrasive layer side of conventional coated abrasive paper is painted in one color, which is the color of the abrasive itself, and the color of the abrasive is generally limited to brown or black. Therefore, the abrasive layer side of conventional coated abrasive paper has poor color appearance.

An object of the present invention is to provide a coated abrasive paper that can overcome the problems of the conventional art as described above.

Means for Solving the Problems According to the present invention, in a coated abrasive paper comprising a base material and an abrasive layer, a printing layer is applied to the abrasive layer side.

Embodiments Next, the present invention will be described in detail with regard to embodiments of the present invention with reference to the accompanying drawings and FIGS. 1 and 2.

FIG. 1 is a partially enlarged sectional view of coated abrasive paper as an embodiment of the present invention. In the coated abrasive paper of this example, a printed layer 13 is provided on the surface of a base material 11, and an abrasive layer 12 is provided on the printed layer 13. In this embodiment, the abrasive layer 12
is made of a transparent or translucent abrasive material so that the printed layer 13 underneath can be seen.

Next, to explain an example of the manufacturing process of such coated abrasive paper, first, a suitable base material 11 such as kraft paper, Japanese paper, cotton cloth, blended cloth, polyester film, etc. is prepared, and the base material 11 is Rubber plate on the surface of
The printed layer 18 is provided by printing a desired pattern including the type of abrasive material, particle size, name of the manufacturing company, brand mark or design, etc. using a synthetic resin plate. Such a printed layer 13 may be provided on the base material 11 before the base material 11 is subjected to sealing treatment, or
It may be provided on the base material 11 which has been subjected to sealing treatment. After that, the surface of the base material 11 is coated with a transparent or translucent primary adhesive such as a natural adhesive (glue, etc.) or a synthetic resin adhesive (epoxy resin, etc.), and on top of that, a fused alumina-based WA ( A transparent or semi-transparent abrasive such as white alundum) or flint (natural) is applied, and a natural adhesive (glue, etc.) or synthetic resin adhesive (epoxy resin, etc.) is added to fix the abrasive grains. etc.) is coated with a transparent or semi-transparent secondary adhesive,
Drying completes the application of the abrasive layer 12. The secondary adhesive may be colored, for example, yellow, red, or green. The abrasive layer 12 thus formed is
It is transparent or translucent so that the underlying printed layer 13 is visible through the abrasive layer 12.

FIG. 2 is a partially enlarged sectional view of coated abrasive paper as another embodiment of the present invention. In the coated abrasive paper of this example, an abrasive layer 22 is provided on the surface of a base material 21, and a printed layer 23 is provided on the abrasive layer 22. In this embodiment, the abrasive layer 22
may be opaque.

Next, to explain an example of the manufacturing process of such coated abrasive paper, first, a suitable base material 21 such as kraft paper, Japanese paper, cotton cloth, blended cloth, polyester film, etc. is prepared, and then the surface of the base material 21 is above,
Coating with primary adhesive such as natural adhesive (glue, etc.) or synthetic resin adhesive (epoxy resin, etc.)
On top of that, abrasive grains such as fused alumina type A (alundum), silicon carbide (SiC), garnet (natural), emery (natural), etc. are applied, and the abrasive grains are further fixed. Therefore, a secondary adhesive coating such as natural adhesive (glue, etc.) or synthetic resin adhesive (epoxy resin, etc.) is applied, dried,
Application of the abrasive layer 22 is completed. Finally, a desired pattern including the type of abrasive material, particle size, manufacturing company name, brand mark or design, etc. is printed on the upper surface of the abrasive layer 22 using a rubber plate, a synthetic resin plate, etc. to form a printed layer. Give 23. In this example, the printed layer was applied after coating with the secondary adhesive, but the present invention is not limited to this, and the printed layer is applied after applying the abrasive grains and before coating with the secondary adhesive, A secondary adhesive may then be coated. However, in this case, the secondary adhesive needs to be transparent or translucent.

Effects of the invention Since the coated abrasive paper of the invention has the above-mentioned configuration, the type of abrasive, particle size, etc. can be seen from the side of the abrasive layer, which is advantageous to the user. The confirmation work becomes easier. In addition, according to the structure of the coated abrasive paper of the present invention, it is possible to create an aesthetically pleasing polished surface by variously devising the pattern of the printed layer, and by coloring the printed layer, it is possible to create a polished surface with an aesthetic appearance. It can also be overflowing.
