Problems solved by technology

At present, the internal pores of the polishing discs produced in the market are unevenly distributed, and the hardness of the abrasive grains is high. Many of them are much higher than the hardness of glass products. For example, the polishing discs with alumina as abrasive grains are particularly easy to cause scratches on the glass surface hurt
The current polishing discs have poor wear resistance, and the temperature rises seriously during the polishing process, resulting in changes in the shape of the workpiece. The surface of the polished workpiece is prone to scratches and fried patterns, which seriously affects the polishing quality, polishing accuracy and polishing speed of the polished product.
Chinese patent CN102248495A discloses that the abrasive grains required for making the polishing disk are rare earth materials, and the production process is cumbersome and the cost is high; the raw materials required for making the polishing disk disclosed by Chinese patent CN102863903A include carbon nanotubes and caprolactam monomers, which are expensive and cost too high

Embodiment 1

[0015] The room temperature is 32°C and the relative air humidity is 37%. Mix 22 parts of unsaturated polyester resin (307-3) with 0.2 parts of cobalt naphthenate, 17 parts of table salt, 4.975 parts of sodium acetate trihydrate and 0.025 parts of sodium hydrogen phosphate dodecahydrate in a plastic bucket Stir for 6 minutes, and the speed of the mixer is 750r / min. After the reaction is complete and the stirring is uniform, add 54 parts of Fe with a D50 of 1.2 μm 2 o 3 / SiO 2 For nanocomposite particle abrasive, add 0.26 parts of cyclohexanone peroxide and 1.54 parts of washing powder and stir evenly for 15 minutes. After the reaction is complete and stirred evenly, pour it into a steel mold for curing, scrape it flat with a spatula, and cure for 30 minutes. Finally, the polishing disc is formed and the bubbles are uniform, the diameter of the bubbles is about 0.50mm, the hole spacing is about 16mm, and the porosity is about 1.2%. The material removal rate is 182nm / min, and...
