Purpose of the invention This invention is a coated abrasive paper that can grind the surface of metals that are extremely difficult to grind, such as pure titanium and titanium alloys, and dramatically improves the grinding life of the coated abrasive paper. Regarding. Conventional technology Conventional coated abrasive paper is made of pure titanium (titanium alloy), which is said to be a difficult-to-cut material, or an oxide film (scale).
When grinding metals with adhesion, the tips of the abrasive grains wear out quickly and have an extremely short lifespan, making them completely unsuitable for grinding. Furthermore, even if the conventional coated abrasive paper P with cork particles shown in FIG. Although the grinding life was somewhat better than that in the case, the grinding life was still relatively short due to wear and tear. The reason for this is that, as shown in Figure 1, the structure of the conventional coated abrasive paper P with cork particles has cork particles on the surface of the base material B.
are adhered in a single layer with adhesive A, and the abrasive grains G described above are adhered to the surfaces of these cork particles with adhesive A, and the abrasive grains are in the spaces S between the cork particles C and below the cork particles C. This is because the abrasive paper P with cork particles has a problem in that it wears out quickly and is unusable due to the absence of G. Structure of the invention In view of the above-mentioned problems, the present invention has been developed by applying and adhering a mixture of cork particles and relatively coarse abrasive grains with an adhesive to the surface of the base material in an almost single layer, thereby creating a gap between the cork particles. This is a coated abrasive paper in which coarse abrasive grains are also present under the cork particles.The present invention will be explained with reference to the drawings of the embodiment.In Fig. 2, the coated abrasive paper 1 is made of cloth, paper, , elastic particles 3 such as cork particles, vermiculite particles, or rubber particles, and relatively coarse particles of aluminum oxide, silicon oxide, and garnet having a particle size of #40 to #150 are applied to the surface of a base material 2 made of a nonwoven fabric or a combination thereof. , silicon carbide,
Abrasive grains 4 such as boron carbide or zirconia-alumina eutectic are kneaded with an adhesive 5 and applied and fixed in almost a single layer. It has a structure in which the abrasive grains 4 are present in the gaps 6 and the lower side 7 of each elastic particle 3, and the abrasive cloth paper 1 is attached to a grinding device such as a belt sander (not shown). This grinder grinds difficult-to-cut materials such as pure titanium, titanium alloys, or metals with an oxide film (scale). Effects of the invention To explain the effects of the invention with reference to figures of embodiments, in Figs. 3 to 5, the abrasive cloth 1 attached to a belt sander (not shown) is
When rotated and pressed against a titanium alloy or a metal surface with an oxide film (scale) (both not shown), the ground surface a 1 (upper surface in the figure) of the abrasive cloth 1 is sequentially worn away and lowered (base material 2 ), and finally base material 2
It has a structure in which abrasive grains 4 are directly spread and glued on top. In this case, the abrasive grain 4 has a relatively coarse grain size of #40~
Since the roughness is #150, the grinding force is enormous, and since the core is made of elastic particles 3 such as cork particles, and the surrounding surface and gaps 6 are filled with abrasive grains 4 and bonded, the elastic material Due to the cushioning force of the particles 3 and the dust, the abrasive grains 4 do not fall off due to the impact force, and are gradually exposed as new grinding surfaces a 1 and a 2 until finally, as shown in FIG. Since the grinding surface A3 , which is similar to that of the conventional coated abrasive paper bonded directly on top of the paper, can be further ground, the grinding life reaches its end, so the life is significantly extended. Effects of the invention The effects of the invention are shown below using experimental examples of the grinding life of conventional coated abrasive paper, conventional cork belt, and coated abrasive paper of the present application.

However, it is also extremely advantageous that difficult-to-cut materials such as the aforementioned pure titanium or metals with oxide films (scales) can be ground using the abrasive cloth paper of the present invention.
