Method for manufacturing coated abrasive of finished superhard material

Abstract

The invention discloses a method for manufacturing a coated abrasive of a finished superhard material. The method comprises the following steps: singeing, rinsing, striking, soaking, coating, stretching and shaping, uncoiling, trade mark printing, primer coating, electrostatic sand-planting, pre-baking, composite adhesive coating, pre-drying, drying, coiling, flexing, shunt winding, slicing, adhesive coating, model loading, and shaping and curing. The substrate is made from polyester; substrate finishing agent is prepared from phenolic resin cementing agent and plenolic resin binder in the volume ratio of 180 to 100; the substrate is stretched while the substrate is dried at the temperature of between 200 and 220 DEG C; a grinding material is prepared from zirconia aluminum oxide and black silicon carbide; and the binder is prepared from phenol, 37 percent formaldehyde, 86 percent paraformaldehyde, NaOH and water in the volume ratio of 400 to 372 to 198 to 9.2 to 12. The method not only can save energy and reduce consumption, but also can improve the manufacture efficiency; and the coated abrasive tools of the finished superhard material manufactured by the method not only resists abrasion, but also has good stability of the substrate.

Description

technical field [0001] The invention relates to a coated abrasive process, which is a method for manufacturing a high-strength, stretch-resistant, superhard and super wear-resistant coated abrasive. Background technique [0002] At present, the metal and plate processing industry in the market needs a large number of ultra-hard and ultra-wear-resistant abrasives for high-gloss, high-level grinding. Generally, coated abrasives can only be polished for low-end products, and cannot meet the requirements of high-end products. The performance is that after grinding and polishing the high-end metal or plate surface, the cutting force is not enough, and the required thickness cannot be ground according to the requirements. The matrix has ductility, and deformation will occur during high-speed grinding, causing uneven scratches on the surface of the workpiece. If general coated abrasives are not improved, it will seriously affect the development speed of high-end products in my cou...

Generally, coated abrasives can only be polished for low-end products, and cannot meet the requirements of high-end products

The performance is that after grinding and polishing the high-end metal or plate surface, the cutting force is not enough, and the required thickness cannot be ground according to the requirements. The matrix has ductility, and deformation will occur during high-speed grinding, causing uneven scratches on the surface of the workpiece.

If general coated abrasives are not improved, it will seriously affect the development speed of high-end products in my country's processing industry
