Description

Diamond abrasive cloth and manufacturing method thereof

The present invention relates to a diamond abrasive cloth and a method of manufacturing the same.

Background technique

The existing common abrasive cloth is mostly used for the grinding of the surface of metal parts, wood parts, etc., and the diamond abrasive cloth is mostly used for the grinding of the surface of the non-metallic hard and brittle material. At present, the existing diamond abrasive cloth manufacturing process: First, after the diamond powder is mixed with the adhesive, directly coated or heat-pressed on the base fabric of the non-woven fabric (or made of other materials) to form an abrasive cloth (such as Figure 1), but the abrasive cloth is not sharp enough, so its grinding is not strong enough. At the same time, because the diamond powder is mixed with rubber and plastic adhesive, it is not resistant to high temperature and affects the service life of the abrasive cloth. Second, the diamond powder is passed through the metal. The layer or the metallization layer is directly electroplated on the surface of the metal cloth or the woven fabric, so that the metal layer is easily peeled off, which affects the service life of the diamond abrasive cloth. The Chinese patent database discloses a new type of diamond grinding belt for non-metal polishing machine, CN02246632.0, which is a flexible metal sheet bonded to a nylon substrate and then plated with diamond on the surface of the metal sheet. Although the belt is sharp, Since the diamond is plated on the surface of the metal sheet, the adhesion to the substrate is not strong, and the problem of diamond falling off is likely to occur during use, which affects the service life.
