Abstract

(57) [Summary] [Purpose] The purpose is to provide an abrasive cloth paper that has a longer life. In an abrasive cloth paper 1 in which an abrasive material 4 is laminated on a base material 2 with an adhesive 3 interposed therebetween, an average particle diameter of at least twice the average particle diameter of the abrasive material 4 is provided during lamination. The aggregates 5 and 5, which are more abrasion resistant than the adhesive 3, are mixed and configured.

[Industrial applications]

 The present invention relates to improvement of abrasive cloth paper.

[0002]

[Prior art and its problems]

 Conventionally, in order to improve the life of abrasive cloth paper, as shown in the cross-sectional view of FIG. 3, an abrasive material 4 such as diamond particles is provided on a base material 2 such as cloth with an adhesive 3 interposed therebetween. Although they are laminated in multiple layers, in many cases, when used for grinding work, the chips of the material to be ground scrape off the adhesive 3 holding the abrasive 4, and the abrasive 4 falls off early. However, there is a problem in that the abrasive material 4 becomes unusable before the performance of the abrasive material 4 is sufficiently exhibited, and the life of the abrasive cloth paper is significantly reduced.

[0003]

[Means for Solving the Problems]

 The present invention has been devised in view of the above-mentioned conventional problems, and an object thereof is to provide an abrasive cloth paper which can improve the life. The gist of the present invention is to provide an abrasive material via an adhesive on a base material. In the laminated abrasive cloth paper, an aggregate having an average particle diameter that is at least twice the average particle diameter of the abrasive material and having more wear resistance than the adhesive is mixed in the laminated abrasive paper. is there.

[0004]

[Action]

 Abrasives are laminated in multiple layers in the adhesive. Aggregates with an average particle size more than twice that of the abrasives are mixed in the lamination, so the chips of the material to be ground scrape the adhesive during use. At the time of removal, the aggregate is also shaved at the same time, and since this aggregate is more abrasion resistant than the adhesive, the rate of scraping off the adhesive is reduced, and the abrasive material falls off earlier as in the past. The abrasive material is held firmly to the adhesive without any abrasion, which improves the life of the polishing cloth paper.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional configuration diagram of the abrasive cloth paper of the first embodiment. The abrasive cloth paper 1 comprises a base material 2 such as cloth and an abrasive material 4, 4 in multiple layers with an adhesive 3 such as a bond. 4 are laminated, and the abrasive 4 is composed of, for example, diamond particles or CBN (cubic boron nitride) particles. In this example, aggregates 5, 5, and 5 are mixed in the lamination of the abrasives 4, 4, and 4 and the adhesive 3, and the aggregate 5 is a particle having abrasion resistance higher than that of the adhesive 3. And rubber particles, plastic particles, metal particles, inorganic material particles, etc., for example, nylon particles are used as the plastic particles, and brass and nickel particles are used as the metal particles. Glass beads and the like are used as the inorganic material particles. The average particle diameter of the aggregate 5 is at least twice the average particle diameter of the abrasive material 4.

When the abrasive cloth paper 1 configured as described above is ground, the material to be ground is ground by the abrasive material 4 exposed on the surface, and chips generated at this time scrape off the adhesive 3 gradually. However, in this example, since the aggregate 5 is present, the cutting chips scrape off the aggregate 5 and the adhesive 3 is not sharply scraped off. Abrasive material 4 held by No. 3 does not drop off one after another, and abrasive material 4 can be maintained in a state of being favorably held by adhesive agent 3 and can maintain good grinding performance. The life of the abrasive cloth paper is significantly longer than that of the conventional one. The type and particle size of the aggregate 5 can be appropriately changed depending on the application. For example, for a hard work material, it is preferable to use the aggregate 5 having a high hardness and a large particle size.

Next, FIG. 2 shows a second embodiment. In FIG. 2, the aggregate 5 is spherical, and other configurations are the same as those of the first embodiment. Also in this example, the scraping of the adhesive 3 by the chips of the work material is effectively prevented by the aggregate 5, the abrasive 4 does not fall off early, and the life of the abrasive cloth paper is improved. To do.

[0008]

[Effect of device]

 The present invention relates to an abrasive cloth paper comprising a base material and an abrasive material laminated on the base material via an adhesive, wherein the average particle diameter of the abrasive material is not less than twice the average particle diameter of the adhesive material. By mixing the aggregate with more abrasion resistance than before, the abrasive does not fall off as early as in the past, and the abrasive prevents scraping of the adhesive and the abrasive is good. In addition, it maintains the state of being held by the adhesive and has the effect of significantly improving the life of the abrasive cloth paper.
