Problems solved by technology

[0002] At present, most domestic glass, ceramics and other processing enterprises use the traditional free abrasive grinding process, that is, add free abrasive to the cooling water for grinding. This grinding method has poor stability, low cutting efficiency, low yield rate of processed products and subsequent Difficult processing and other issues
In order to solve the above-mentioned technical problems, the prior art makes grinding pads by coating abrasives and bonding agents on non-woven fabrics, but when using the existing grinding pads for grinding, the abrasive consumption on the grinding pads is fast, making the wear of the abrasives change. Blunt, there are more scratches on the surface of the product after grinding, and the grinding and polishing effect is poor

Abstract

The invention relates to the technical field of grinding tools, in particular to a fine polishing sponge and a preparation method thereof. The fine polishing sponge structurally comprises a sponge layer, a base cloth layer and a grinding layer; one side, close to the grinding layer, of the base cloth layer is provided with a bonding layer, wherein the bonding layer is used for increasing the adhesive force between the base cloth layer and the grinding layer; the grinding layer comprises a resin matrix, a plurality of main grinding units which are adhered to the resin matrix and used for grinding and polishing, and a plurality of auxiliary grinding units used for assisting the main grinding units to carry out grinding and polishing; the main grinding units are conical, and the tips of the main grinding units protrudes out of the upper surface of the resin matrix, the end parts of the main grinding units protruding from the resin matrix is higher than the end parts of the auxiliary grinding units protruding from the resin matrix; the base cloth layer is formed by interweaving a plurality of warps and a plurality of wefts, the warps comprise a plurality of sizing parts arranged abovethe wefts, and the bonding layers are arranged on the sizing parts, the grinding layer is arranged on the bonding layer. The fine polishing sponge and the preparation method of the fine polishing sponge has advantages that the grinding material consumption speed is low during grinding, and the grinding and polishing effects are good.
