Problems solved by technology

However, the main component of pyrite is iron disulfide (FeS 2 ), because iron disulfide is easily oxidized into iron dioxide and sulfur dioxide in the air, and sulfur dioxide has strong oxidizing properties, and it can form corrosive sulfurous acid when combined with water in the air, which will corrode the metal being cut or polished. This is a disadvantage of pyrite as a lubricant
[0004] The green ultra-thin resin grinding wheels on the existing market all have problems such as short service life and low product strength, which affect work efficiency, increase the use cost and deteriorate the safety factor of use.

Abstract

The invention relates to a green ultrathin resin grinding wheel and a preparation method thereof, and belongs to the technical field of grinding tools. The grinding wheel comprises an upper reinforcedglass fiber mesh sheet and a lower reinforced glass fiber mesh sheet and a cutting body arranged between the two reinforced glass fiber mesh sheets, wherein the cutting body is composed of the following raw materials of, by weight, 90-110 parts of abrasive materials, 10-15 parts of phenolic resin liquid, 15-25 parts of phenolic resin powder, 5-10 parts of potassium cryolite, and 20-30 parts of filler; and the grinding material is composed of the following raw materials of, by weight, 25-30 parts of primary single-crystal corundum, 40-50 parts of primary-grade iridium-plated white corundum and25-30 parts of primary zirconium corundum. Compared with the existing similar ultrathin grinding wheel resin product, the green ultrathin resin grinding wheel has the advantages that the cutting lifeis prolonged by 60-70 %, the cutting sharpness is improved by 50-60 %, meanwhile, burning and burrs are avoided, the working efficiency is greatly improved, and the using cost is reduced.

Description

technical field [0001] The invention belongs to the field of grinding tools, and in particular relates to a green ultra-thin resin grinding wheel and a preparation method thereof. Background technique [0002] The thickness of ultra-thin resin grinding wheel is generally 0.06mm~0.5mm, without matrix. This type of grinding wheel is mainly suitable for high-precision cutting and grooving of optical glass, ceramics, and semiconductor packaging materials. This type of grinding wheel has the advantages of good self-sharpening, high cutting efficiency, and good cutting quality. It is an indispensable tool for high-efficiency, energy-saving, high-precision and automatic cutting. [0003] Resin grinding wheels are widely used in mechanical metallurgy, construction, military industry, railway construction and other fields. They are mainly used for cutting and grinding general metal materials such as steel pipes, steel bars, and steel bars. In order to enhance the grinding lubricati...
