Embodiment

[0022] Embodiment: a kind of coated grinding tool, comprises substrate 1, binding agent and abrasive material 2, is characterized in that: also has some cork particles 3, and described several cork particles and abrasive are adhered to described substrate together by bonding agent superior.

[0023] The abrasive is distributed in the gaps between the cork particles and on the surface of the cork particles.

[0024] The cork particles are 5-10 mesh larger than the abrasive.

[0025] The adhesive includes a primer layer 4 and an overcoat layer 5, the thickness of the undercoat layer is 0.06-0.1 mm, and the thickness of the overcoat layer is 0.1-0.15 mm. Generally, the coating of the primer in the coated abrasive tool is about 0.03-0.05mm, and the coating of the compound glue is about 0.07-0.1mm. In the present invention, because the cork particles are relatively large, the thickness of the primer and the compound glue must be Increase by about 0.03-0.05mm.

Abstract

The invention discloses a coated abrasive tool and a processing method thereof, the coated abrasive tool and the processing method thereof mainly follows the principles that cork particles have good elasticity and have very good buffer effect; the cork particles are coated onto a matrix by adhesive; then an abrasive material is coated in the gaps of the cork particles, so that the coated abrasive tool which has elastic buffer effect and can finely grind at high speed is produced; and the coated abrasive tool has the advantages of high finish degree of a grinding surface, good abrasive resistance and durability and the like.

Description

technical field [0001] The invention relates to a coated abrasive tool and a manufacturing method thereof, in particular to a high-speed fine-grinding emery cloth with elastic buffering effect 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 ...
