A kind of manufacturing method of flexible 3D grinding tool

Abstract

The invention relates to the technical field of grinding tools, in particular to an adhesive composition for a flexible 3D grinding tool, the flexible 3D grinding tool and a manufacturing method of the flexible 3D grinding tool. The adhesive composition for the flexible 3D grinding tool is prepared from the following raw materials in parts by weight: 2 to 5 parts of an adhesive A, 1 to 20 parts of leveling resin B and 50 to 200 parts of an adhesive C, wherein the adhesive A is prepared from the following raw materials in parts by weight: 15 to 30 parts of light-cured resin a and 70 to 85 parts of heat-cured resin a; the leveling resin B is light-cured resin b; and the adhesive C is prepared from the following raw materials in parts by weight: 15 to 30 parts of light-cured resin a and 70 to 85 parts of heat-cured resin a. The adhesive composition disclosed by the invention is relatively high in adhesive property, so that relatively high adhesive property is realized among all layers of the 3D grinding tool; and therefore, the manufactured 3D grinding tool is relatively high in adhesive strength and stability, and no phenomenon of interlaminar separation in a use process of the 3D grinding tool is caused.

Description

technical field [0001] The invention relates to the technical field of abrasive tools, in particular to an adhesive composition for flexible 3D abrasive tools, a flexible 3D abrasive tool and a manufacturing method thereof. Background technique [0002] Humans have long used natural grinding stones to process tools such as stone knives, stone axes, bone tools, horn tools, and tooth tools; in 1872, the first artificial grinding stone made of natural abrasives and clay appeared in the United States. Abrasives—ceramic grinding wheels; around 1900, artificial abrasives came out, and various abrasives made of artificial abrasives were produced one after another, creating conditions for the rapid development of grinding and grinding machines. [0003] Abrasives are distinguished according to their basic shape and structural features, including bonded abrasives and coated abrasives. Bonded abrasives are tools with a certain shape and a certain grinding ability made of abrasives (g...

AI Technical Summary

Problems solved by technology

Consolidated abrasive tools are tools made of abrasives (grinding materials) and binders with a certain shape and certain grinding ability, including grinding wheels, grinding heads, oilstones, sand tiles, etc., and have the characteristics of high service life and high cutting force. , but it is not suitable for processing complex profiles, and it is easy to cause deep scratches or even burns to the workpiece during use

Coated abrasives refer to abrasives made by adhering abrasives to flexible substrates (cloth, paper, plastic film, etc.) Good, easy to use, wide applicability, suitable for large area and complex surface processing, but because it is obtained by coating processing, the abrasive is single or multi-layer, and its life is much lower than that of bonded abrasives. In the process, clogging and other situations are easy to occur, which further reduces the service life and grinding effect of coated abrasives
