Abstract

The invention discloses a chemical nickel-plating diamond abrasive resin grinding wheel. The chemical nickel-plating diamond abrasive resin grinding wheel is composed of the following raw materials in parts by weight: 570-600 parts of CBN grinding material, 90-100 parts of phenol, 96-110 parts of 35-40% formaldehyde solution, 5-7 parts of boric acid, 2-6 parts of hexamethylenetetramine, 13-20 parts of aniline, 60-70 parts of diamond powder with particle sizes of 30-40[mu]m, 0.7-1 parts of dimethylolpropionic acid, 2-3 parts of ammonium metaborate, 0.08-0.1 parts of stannous chloride, and 0.05-0.1 parts of palladium chloride. According to the chemical nickel-plating diamond abrasive resin grinding wheel disclosed by the invention, the surface of the diamond powder is plated by means of chemical nickel-plating, so that the sharpness of abrasive particles can be improved, the strength can be enhanced, and an effect of avoiding burning for workpieces is acted.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to an electroless nickel-plated diamond abrasive resin grinding wheel and a preparation method thereof. Background technique [0002] With the continuous improvement of the speed of automobiles and airplanes, the requirements for friction materials such as transmission and braking are more stringent, and the matrix, as an important part of friction materials, has always been the focus of development and research. Phenolic resin, epoxy resin, styrene-butadiene rubber and polytetrafluoroethylene can be used as the matrix of friction materials, but epoxy resin, styrene-butadiene rubber and polytetrafluoroethylene have poor wear resistance, heat resistance and Adhesive properties limit its application in friction materials. The advantages of phenolic resin in heat resistance, bonding performance, mechanical properties, molding performance and cost make it the most commonly used...
