Novel glass polishing plate and manufacturing method thereof

Abstract

A novel glass polishing plate and a manufacturing method of the novel glass polishing plate are characterized in that the raw materials of the polishing plate comprise abrasive particles, padding, resin, curing agents and accelerants, wherein the abrasive particles are magnesium aluminate spinel kernel/shell compound abrasive particles, the padding comprises heat-conduction padding, active padding, water-soluble pore-forming agents and active pore-forming agents, and the resin is unsaturated polyester resin. The novel glass polishing plate and the manufacturing method of the novel glass polishing plate have the advantages that an abrasive tool is high in porosity and can contain chips conveniently; the temperature of an abrasive area is low, so that workpieces will not crack; the polishing process is carried out in a 'flexible polishing' mode, so that the micro conditions of a polished surface is improved, and the roughness is lowered.

Description

technical field [0001] The invention belongs to the field of glass polishing, and in particular relates to a glass polishing disc and a manufacturing method thereof. Background technique [0002] Glass processing includes cutting, grinding, polishing and other processes. Polishing is the last process, and its brightness directly affects product quality. Polishing discs are indispensable polishing tools for high-end glass handicraft processing. The polishing discs used are rare earth oxide Cerium is used as a polishing disc for grinding abrasive grains. The Chinese patent publication number is CN102114615A. Although it solves the shortcomings of the previous polishing discs, such as low cutting efficiency, low surface finish, long polishing time, and low work efficiency, the skyrocketing price of rare earths has caused many Polishing companies have lost a lot of money. Chinese Patent Publication No. CN102120315A discloses a polishing disc using modified diamond as abrasive g...

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

Chinese Patent No. 201110231332.7 discloses a glass polishing disc with aluminum oxide-cerium oxide core-shell composite abrasive grains as abrasive grains and its manufacturing method without adding rare earths.
