Composite abrasive cloth

Abstract

The invention discloses a composite abrasion cloth which comprises a surface abrasive cloth, a middle abrasive cloth and an abrasive paper base body. The surface abrasive cloth is arranged on the middle abrasive cloth, the abrasive paper base body is arranged beneath the middle abrasive cloth, and the surface abrasive cloth comprises surface layer non-woven fabric, a coarse grain abrasive material and a surface layer binder, wherein the coarse grain abrasive material and the surface layer binder are soaked in the surface non-woven fabric. The middle abrasive cloth comprises a middle layer non-woven fabric, a fine grain abrasive material and a middle binder, wherein the fine grain abrasive material and the middle binder are soaked in the middle layer non-woven cloth. The middle binder and the surface layer binder are in the same model. Through the above mode, according to the composite abrasive cloth, the surface abrasive cloth and the middle abrasive cloth are compounded together, in the working process, the coarse grain abrasive material in the surface abrasive cloth is used for conducting rough polishing first, after continuous loss, the fine grain abrasive material in the middle abrasive cloth is exposed out to conduct fine polishing, the utilization rate of materials is high, the frequency for clamping the abrasive cloth in the polishing process is reduced, the working efficiency is improved, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of abrasive paper design, in particular to a composite abrasive cloth. Background technique [0002] Sandpaper is a tool often used in the grinding and polishing of workpieces or walls. According to different purposes and usages, there are thousands of types of sandpaper, and the organizational structure and abrasive particle size are also different. [0003] The surface of the sandpaper used for polishing is relatively fine, but it is still divided into several grades according to the abrasive grain size used. The polishing of the workpiece is a step-by-step process. Before the surface of the workpiece is finely polished, it is often necessary to use coarse sandpaper for rough polishing. The entire polishing process needs to use at least two types of sandpaper. Therefore, the polishing machine or polishing rod also It is necessary to prepare for multiple rotations, which consumes a lot of funds, and it is inconvenie...

The polishing of the workpiece is a step-by-step process. Before the surface of the workpiece is finely polished, it is often necessary to use coarse sandpaper for rough polishing. The entire polishing process needs to use at least two types of sandpaper. Therefore, the polishing machine or polishing rod also It is necessary to prepare multiple rotations, which consumes a lot of funds, and it is inconvenient to replace and use, and the work efficiency is low
