Abstract
The invention provides a net sand-coated abrasive die. The net sand-coated abrasive die comprises a base material as well as an adhesive layer and an abrasive material layer which are located on one surface of the base material, wherein the base material is elastic knitted or woven fabric provided with longitudinal fibers which are relatively densely arranged but are not provided with obvious holes and relatively flat surfaces, transverse expansion is carried out under certain tension conditions, the flat surfaces are changed into porous net structures, and transverse expansion is not carried out in the manufacturing process of the base material but is carried out in the manufacturing process of the net sand-coated abrasive die. An adhesive is coated on the fabric base material which is dense or is not provided with obvious net holes. After adhesive coating or sanding, transverse drawing is carried out on the base body, and the base body is expanded into a net. Due to the use of the relatively dense base material, the adhesive coating uniformity and flatness of the base material can be effectively improved, adhesive coating control difficulty is reduced, and the limitation of a traditional manufacturing mode which directly uses an open base material as the base body is broken through.
