High-wear-resistance wiredrawing non-woven fabric grinding material, preparation method and application thereof

Abstract

The invention provides a high-wear-resistance wiredrawing non-woven fabric grinding material, a preparation method and application thereof. The grinding material comprises a base material and slurry, wherein the base material is of a three-dimensional net structure formed by staggering a plurality of nylon fibers with different deniers and higher crimpness, the wear-resistant slurry comprises the following components in parts by weight: 400-800 parts of brown fused alumina abrasive, 150-300 parts of waterborne epoxy, 3-10 parts of a thickening agent, and 50-100 parts of water. According to the invention, the grinding material is selected, three nylon fibers with different deniers, different properties and high wear resistance are used to prepare a highly staggered three-dimensional net structure, and a needling process in a cotton making process is combined, so that the tensile strength and tear strength of the grinding material are greatly improved, and the finally formed grinding tool is also a page-shaped wheel which is high in heat dissipation, high in flexibility and high in porosity, and falling grinding materials are easy to remove.

Description

technical field [0001] The invention relates to the field of abrasive materials, in particular to a high wear-resistant drawing non-woven abrasive material and its preparation method and application. Background technique [0002] Stainless steel wire drawing generally has several effects: straight silk pattern, snow pattern, nylon pattern. Straight silk pattern is an uninterrupted pattern from top to bottom. Generally, it is enough to use a fixed wire drawing machine to move the workpiece back and forth. The snow pattern is the most popular one, which is composed of a little bit of regular dots, which can be achieved with worm sandpaper. Nylon pattern is composed of lines of different lengths. Because the nylon wheel is soft, it can grind uneven parts to achieve the effect of nylon pattern. [0003] In the prior art, the polishing effect of sandpaper is good, but it is not strong for complex surface workpieces, it is difficult to meet the polishing requirements, and the we...

Problems solved by technology

However, because its structure is difficult to make uniform, it is easy to cause poor local drawing effect

Moreover, the heat dissipation performance of the nylon wheel is not good enough, which can easily cause burns to the workpiece. The abrasive falls off during polishing, but due to the low extrusion force and porosity, it remains on the contact surface of the workpiece and continues to participate in polishing, thereby scratching the workpiece.
