[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

Embodiment 1

[0021] The nylon glass polishing disc in this example is made by the centrifugal casting molding process. 1 component A caprolactam monomer is heated and melted, 2 components B abrasive grains and component C filler are used, vigorously mechanically stirred, and ultrasonically dispersed, and 3 components are used. When the vacuum degree is greater than 0.1 MPa and the temperature is 130°C, vacuumize and dehydrate completely, add component D catalyst, stir evenly, 4 continue to vacuumize and dehydrate completely, remove the vacuum, add component E co-catalyst, stir evenly, 5 cast until preheating In the mold, centrifugally cast for 20 minutes, cooled naturally to room temperature, and demolded to obtain a single-cast MC nylon glass polishing disc. The mass ratio of each raw material component of the nylon glass polishing disc is: caprolactam monomer 55; alumina-cerium oxide core-shell composite abrasive grain 30; filler 14 (specifically graphite 1.5, aluminum nitride 1.5, ammoni...

Embodiment 2

[0023] The glass polishing disc in this embodiment adopts the manufacturing process of Embodiment 1. The mass ratio of each raw material component of nylon glass polishing disc is: caprolactam monomer 70; alumina-cerium oxide core-shell composite abrasive grain 20; filler 8.6 (specifically graphite 1, aluminum nitride 1, ammonium fluoride 1.6, sugar 5) ; Catalyst 0.6; Cocatalyst 0.8.

Embodiment 3

[0025] The glass polishing disc in this embodiment adopts the manufacturing process of Embodiment 1. The mass ratio of each raw material component of the nylon glass polishing disc is: caprolactam monomer 60; alumina-cerium oxide core-shell composite abrasive grain 25; filler 14 (specifically carbon nanotube 1, aluminum nitride 1, ammonium fluoride 1 fluoride Sodium 1, sugar 10); catalyst 0.5; co-catalyst 0.5.

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.
