Embodiment

[0021] Embodiment: a kind of coated abrasive tool is made of substrate 1, primer layer 2, glue layer 4, several cork grains 3 and several abrasive grains 5, and the primer layer is bonded on the base Surface, the size adhesive layer is bonded to the upper surface of the primer layer, all the cork particles are not bonded between the primer layer and the size layer, and all the abrasive grains are bonded to the The compounded layer, wherein, a part of the abrasive grains is covered in the compounded layer, and another part of the abrasive grains exposes part of the volume in the compounded layer.

[0022] Cork, commonly known as cork and cork, is the outer skin product of tree species with a well-developed cork layer, and the surface protection tissue after the stems and roots grow thicker. Cork particle size is divided into three particle sizes, which can be specified according to customer requirements.

[0023] The size of abrasive grains can be made according to customer ne...

Abstract

The invention discloses a coated abrasive tool and a manufacturing method thereof; the coated abrasive tool is formed by a base, a primer layer, a compound adhesive layer, a plurality of softwood particles and a plurality of abrasive particles; the coated abrasive tool can be manufactured through the steps of primer coating, gravity sand plantation, predrying, compound adhesive coating, main drying and the like; the coated abrasive tool can avoid very deep scratches from appearing on a workpiece so that the grinding surface is kept very well; the number of the abrasive particles is 6 to 8 times more than that of the abrasive particles of the traditional coated abrasive tool in unit area; therefore, in the using process, after part of particles fall, the new abrasive particles in unit area keep on taking part in grinding; and compared with the traditional coated abrasive tool, the coated abrasive tool has good grinding capacity, durability and persistence and very stable grinding performance.

Description

technical field [0001] The invention relates to a coated abrasive and a manufacturing method thereof, in particular to a coated abrasive with good wear resistance and durability and a manufacturing method thereof. Background technique [0002] Coated abrasives are abrasives made by adhering abrasives to flexible substrates with adhesives. The main varieties are abrasive cloth (paper) and abrasive belts, which are widely used in metal materials, wood, ceramics, plastics, and leather. Grinding, polishing and sanding of non-metallic materials such as rubber and paint putty. [0003] At present, my country's coated abrasives are mainly composed of three parts: abrasive, binder and matrix. The manufacturing process of coated abrasives generally includes substrate treatment, primer coating, sand planting, recoating (gluing), drying and cutting. At the same time, most of the sand planting methods used in my country's coated abrasive tools are gravity sand planting and electrostat...
