Non-woven fabric grinding block for stone polishing and manufacturing method of non-woven fabric grinding block

Abstract

The invention discloses a non-woven fabric grinding block for stone polishing and a manufacturing method of the non-woven fabric grinding block. The non-woven fabric grinding block comprises the following components in percentage by weight: 20-30% of non-woven fabric fiber, 15-30% of grinding material, 5-15% of filler, 20-35% of resin adhesive, 0-5% of wax and 0-5% of pigment. The characteristic that a hard material is used as a grinding tool in the prior art is changed, relatively soft non-woven fabric fibers and soft resin are selected as carriers of the grinding material, proper softness is controlled by utilizing a three-dimensional structure of the non-woven fabric, the grinding tool is well attached to the surface of the stone in the grinding and polishing process, hard collision scratches are avoided, and shadows and scratches are not likely to be generated. In addition, the grinding material held by the resin also has a certain grinding effect, so that the polished and ground stone surface is finer and smoother, and the glossiness is higher. And the board surface is beautiful and bright. The polishing agent is used for polishing stones, and the glossiness can be improved by 5-20 degrees after the polishing agent is arranged behind a magnesia abrasive block or an oxalic acid composite abrasive block.

Description

technical field [0001] The invention relates to the technical field of polishing abrasives, in particular to a non-woven abrasive block used for stone polishing and a manufacturing method thereof. Background technique [0002] Stone polishing is the process of using mechanical equipment to quickly run the grinding block to grind the stone, grind the rough surface of the stone, reduce the roughness of the stone surface, and improve the surface gloss. Stone polishing usually uses "dry polishing" and "wet polishing" to achieve the polishing effect, and there will be strong reflected light on the surface of the product, which is commonly referred to as gloss. After grinding and polishing, the surface of the stone is smooth and smooth, with a clear texture and bright texture. Therefore, stone polishing is a crucial process to improve the quality of the stone. [0003] A grinding block is a workpiece that is combined in a certain form by abrasives with grinding action. The polis...

Problems solved by technology

The existing stone polishing abrasives such as diamond abrasives, bitter soil abrasives or resin abrasives, and oxalic acid composite abrasives are hard and have good cutting force, but the softness is not enough. After the stone reaches a certain glossiness, such as 90 degrees Finally, if you continue to use hard resin grinding blocks and oxalic acid composite grinding blocks, scratches will occur, and it is difficult to further increase the luminosity, and scratches such as filaments are prone to occur.

In this regard, there is a soft felt plus polishing powder and polishing wax on the market for wet polishing, which can further improve the luminosity, but the polishing powder and the soft felt are not integrated, and the consumption of more polishing powder makes the cost high, and it cannot be compared with the previous rough grinding. The polishing group is composed of a polishing group for continuous polishing, and the processing is more troublesome
