なうようにした研磨ベルトに関する。Description: TECHNICAL FIELD The present invention relates to a polishing belt used for polishing a metal surface or the like, and in particular, an abrasive material such as abrasive grains is adhered to the surface of a paper base paper and is rotated. The present invention relates to a polishing belt which is stretched endlessly between a pair of driven rolls, and is brought into pressure contact with an object to be polished during the circulation drive to perform polishing.

あった。(Prior Art) In such a polishing operation, generally, a polishing aid, which is an oily liquid, is sprayed on the contact portion between the polishing belt and the object to be polished in order to cool the object to be removed and to remove polishing debris. Therefore, there is a problem that a slip occurs between the polishing belt and the roll that circulates the polishing belt to cause the belt to break.
このため、従来、例えば実願昭57−115216号（実開昭

No. 59-19261), as in the first embodiment of the invention disclosed in the invention, on the back surface of the base cloth paper (the surface on the side in contact with the roll),
Using an uneven patterning roll or the like, the unevenness of the thick and thin portions of the base cloth paper is formed in a pattern, thereby achieving an effect of oil film adhesion between the base cloth paper and the roll, or the above-mentioned invention. As in the second example, the entire back surface of the base cloth paper is covered with a layer of mineral powder particles having an adhesive as a binder,
There is one in which the upper surface of the mineral powder layer is made uneven.

させるために、採用することができない。That is, the water absorbed and retained in the base fabric paper is evaporated by the heat of polishing generated during the polishing operation. Since this dehumidification process is forcedly performed by the heat of polishing, it cannot be prevented by the front surface of the base cloth paper, the abrasive layer covering the back surface, and the mineral powder layer. As a result of such dehumidification, the base paper loses its flexibility and is easily broken. Note that, during the polishing operation, the base cloth paper is infiltrated with an oil-based polishing aid, but since the base cloth paper is not lipophilic due to its material, flexibility is not obtained depending on the polishing aid. Then, when the polishing operation is interrupted, the base cloth paper absorbs moisture in the atmosphere to recover its flexibility and withstand reuse, but this moisture absorption process is natural when the polishing belt is left standing. However, unlike the above dehumidifying process, the size of the exposed area of the base cloth paper in the atmosphere is an important factor. However, in the second embodiment, since the front and back surfaces of the base cloth are not exposed and are covered with the adherend layer, the moisture absorption process does not proceed slowly, so that the base cloth is sufficiently It was reused before the flexibility was restored, and the polishing belt was easily broken. In addition, the method of forcibly absorbing the moisture of the dehumidified base fabric paper, for example, the method of removing water from the base fabric paper or immersing the base fabric paper in water, is the amount of water supplied excessively. Cannot be used because it dissolves the binder of the abrasive.
そこで本発明は、ロールと研磨ベルトとの間のスリッ
プ防止と、研磨ベルトの吸湿性の向上とを併せ実現する
ことを、その解決すべき技術的課題とする。Therefore, it is a technical problem to be solved in the present invention to realize both slip prevention between a roll and a polishing belt and improvement of hygroscopicity of the polishing belt.

On the back side of the belt base paper with the abrasive attached to the surface, a friction material having a larger friction resistance than the belt base paper and good adhesion of the belt base paper, in an area ratio of 10 to 40%. It is characterized in that the belt base paper is adhered in a polka dot pattern, and the portion of the back surface of the belt base paper on which the friction material is not adhered is exposed to absorb moisture.

ールと研磨ベルトとの間のスリップが防止される。(Operation) According to the polishing belt of the present invention, since the friction material applied in a polka dot pattern exhibits a strong frictional resistance to the roll, slip between the roll and the polishing belt is prevented.
また、ベルト基紙の裏面側のうちの摩擦材被着部分以

Paper quickly regains flexibility.
（実施例） 次に、本発明の第１実施例を第１図〜第３図に基づい

ものではない。In the above configuration, the binder 3 is an oil resistant adhesive such as glue, and the friction material 5 is an oil resistant material having a larger friction resistance than the belt base paper and good adhesion to the belt base paper, for example, It is a rubber latex such as a nitrile latex, an acrylic latex, or a vinyl acetate latex. The friction material 5 is adhered to the back surface of the belt base paper 2 by a method such as gravure printing, screen printing, or letterpress printing, but the application method is not limited to this.

As shown in the figure, it is stretched between the contact roll 6 and the idler roll 7, and a material 9 to be polished such as a metal coil is pressed against the contact roll 6 by a billy roll 8 to perform polishing by the polishing belt 1. Moreover, during the polishing operation, an oil-based polishing aid is sprayed from the nozzle 10.
次に、本実施例に基づく研磨ベルトと従来の研磨ベル

（１）まず、研磨助剤の存在下でのコンタクトロールと
研磨ベルトの裏面との動摩擦係数は、本実施例のもので
0.85、裏面に摩擦材を被着しないもので0.77であった。(1) First, the coefficient of dynamic friction between the contact roll and the back surface of the polishing belt in the presence of the polishing aid is that of this example.
The value was 0.85, and the value was 0.77 when the friction material was not applied to the back surface.

In this example, the moisture absorption is 13.3 g / m 2 and the tear strength is 773 g (JIS-P-811) after 30 minutes of standing.
According to 6. The same shall apply hereinafter) 2 hours later, the moisture absorption is 2
The tear strength was 5.33 g / m 2 and 1163 g.

本実施例のものに対し、有意の差を認めた。On the other hand, in the case where the friction material is adhered to the entire back surface of the belt base paper, under the same conditions as above, the moisture absorption amount is 7.8 g / m 2 , and the tear strength is 264 g, 2 hours after 30 minutes have elapsed. The amount of moisture absorbed over time is 12.5 g / m 2 , the tear strength is 373 g,
A significant difference was observed with respect to that of this example.
