Glass polishing disk and manufacturing method thereof

Abstract

The invention relates to a glass polishing disk and a manufacturing method thereof. The glass polishing disk is characterized in that raw materials of the polishing disk comprise abrasive particles, filler, resin, a curing agent and a promoter, wherein the abrasive particles are aluminum oxide-cerium oxide core-shell compound abrasive particles or aluminum oxide surface cerium permeated abrasive particles, the filler comprises heat conducting filler, active filler and a pore-forming agent, and the resin is unsaturated polyester resin. The compound abrasive particles adopted by the polishing disk provided by the invention have strong grinding force of alpha-Al2O3 and also have rapid polishing performance of a cerium oxide polishing powder mechanical chemical polishing mechanism, scratches to a glass polished surface are reduced owning to a Ce<3+>-containing cerium oxide soft shell, polishing evenness is high, and finish degree is good. The glass polishing disk disclosed by the invention has the advantages of low price, simple manufacturing process, high gloss increasing speed, long lustre duration time and no crack of a workpiece due to low grinding temperature.

Description

[0001] technical field [0002] 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 [0003] At present, glass processing in glass processing plants includes cutting, rough grinding, fine grinding, polishing and other processes. The polishing process is the last process, and its brightness directly affects the product quality. The polishing disc is an indispensable polishing for the processing of high-end glass crafts. Tool, what is common in the market at present is that polishing disk is fixed on the rotating disk of polishing machine and glass, glass handicraft are polished, and used polishing disk is all the polishing disk of rare earth cerium oxide as grinding grain, and Chinese patent publication number is CN102114615A, Although it solves the disadvantages of low cutting efficiency, low surface finish, long polishing time, and low work efficiency of previous ...

[0003] At present, glass processing in glass processing plants includes cutting, rough grinding, fine grinding, polishing and other processes. The polishing process is the last process, and its brightness directly affects the product quality. The polishing disc is an indispensable polishing for the processing of high-end glass crafts. Tool, what is common in the market at present is that polishing disk is fixed on the rotating disk of polishing machine and glass, glass handicraft are polished, and used polishing disk is all the polishing disk of rare earth cerium oxide as grinding grain, and Chinese patent publication number is CN102114615A, Although it solves the disadvantages of low cutting efficiency, low surface finish, long polishing time, and low work efficiency of the previous polishing discs, the rare earth has increased nearly ten times in a year, causing many polishing companies to lose a lot of money.

The Chinese Patent Publication No. CN102120315A discloses a polishing disc using modified diamond as an abrasive. 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
