MC (Monomer Casting) nylon glass polishing disc and manufacturing method thereof

Abstract

The invention relates to an MC (Monomer Casting) nylon glass polishing disc and a manufacturing method thereof. The MC nylon glass polishing disc is characterized in that the raw materials of the polishing disc consist of abrasive particles, filling materials, caprolactam monomers, a catalyst and a cocatalyst, wherein the abrasive particles are aluminum oxide-cerium oxide nuclear shell composite abrasive particles, and the filling materials consist of heat conducting filling materials, active filling materials and a water-soluble pore forming agent. The MC nylon glass polishing disc has the advantages that 1, the porosity of an abrasive tool is high and the chip holding is facilitated; 2, the temperature of a grinding area is low and a workpiece is not ruptured; and 3, the wear resistance of a bonding agent is high and the service life of the abrasive tool is long.

Description

technical field [0001] The invention belongs to the field of glass polishing, and in particular relates to an MC nylon glass polishing disc and a manufacturing method thereof. Background technique [0002] Polishing discs are indispensable polishing tools for processing high-grade glass handicrafts. Most of the polishing discs used are rare earth cerium oxide as polishing discs for grinding abrasive grains. The Chinese Patent Publication No. is CN102114615A, although the low cutting efficiency of the previous polishing discs has been solved. , The surface finish is not high, the polishing time is long, and the work efficiency is low. However, the skyrocketing price of rare earths has caused many polishing companies to lose a lot. Chinese Patent Publication No. CN102120315A discloses a polishing disc using modified diamond as abrasive grains. Although the service life (wear resistance) is about twice that of rare earth polishing discs, diamond is more expensive than rare eart...

[0002] Polishing discs are indispensable polishing tools for processing high-grade glass handicrafts. Most of the polishing discs used are rare earth cerium oxide as polishing discs for grinding abrasive grains. The Chinese Patent Publication No. is CN102114615A, although the low cutting efficiency of the previous polishing discs has been solved. , the surface finish is not high, the polishing time is long, and the work efficiency is low, but the price of rare earths has skyrocketed, causing many polishing companies to lose a lot

The Chinese Patent Publication No. CN102120315A discloses a polishing disc using modified diamond as abrasive grains. Although the service life (wear resistance) is about twice that of rare earth polishing discs, diamond is more expensive than rare earth, and the cost is too high

However, the unsaturated resin used in the bond has a relatively hard abrasive, and the bond itself has poor wear resistance, which affects the service life of the abrasive
