Abstract

The invention relates to the technical field of grinding tools, in particular to a preparation process of a multilayer-structured 3D grinding tool. The preparation process comprises the steps of: (1)coating of a primer on an elastic membrane; (2) pressing of a square frame; (3) scraping of an abrasive; (4) primary curing of the abrasive; (5) stamping; (6) mold shifting and curing; and (7) compounding of a sponge layer. The multilayer-structured 3D grinding tool is prepared by the preparation process of the multilayer-structured 3D grinding tool; an abrasive layer achieves self sharpness; in the grinding process, abrasive grains can fall layer by layer; and new abrasive grains are exposed constantly after falling, so that the grinding force is stable. In addition, in the prepared multilayer-structured 3D grinding tool, a groove is formed in the middle part of the abrasive layer, so that abrasive chips generated in the grinding process can be easily discharged from the groove, and the blockage problem of the abrasive chips can be prevented; and the prepared multilayer-structured 3D grinding tool is particularly suitable for a wet grinding procedure.

Description

technical field

[0001] The invention relates to the technical field of abrasive tools, in particular to a preparation process of a multi-layer structure 3D abrasive tool. Background technique

[0002] Sponge sand abrasives are widely used in manufacturing, repairing, furniture, decoration and other industries, and have brought great convenience to the above industries, and are still an industrial necessity.

[0003] In the prior art, there are mainly two types of sponge sand abrasives. The first one is obtained by mixing adhesives and abrasive grains and then coated. The second is to apply adhesives on the base material before using Electrostatic sand planting is obtained. There is common defect in above-mentioned these two types of existing sponge abrasive tools: (1) because of its grit easily blunt or come off, therefore cause its abrasive force to be unstable; When the tool is used to grind the workpiece, it is easy to cause the problem of grinding debris clogging.
