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...
Embodiment 2
[0017] The room temperature is 20°C and the relative air humidity is 45%. Mix 23 parts by mass of unsaturated polyester resin (307-3) with 0.26 parts of cobalt naphthenate, 20 parts of white sucrose, 1.99 parts of sodium acetate trihydrate and 0.01 part of dodecahydrate Sodium hydrogen phosphate was mixed and stirred in a plastic bucket for 6 minutes, and the speed of the mixer was 750r / min. After the reaction was complete, 49 parts by mass of Fe with a D50 of 1.6 μm were added. 2 o 3 / SiO 2 Nano-composite particle abrasive, 0.32 parts of cyclohexanone peroxide and 2.42 parts of washing powder are evenly stirred for 15 minutes, and after the reaction is complete and stirred evenly, pour into a steel mold for curing, scrape it flat with a spatula, and cure for 28 minutes Finally, the polishing disc is formed and the bubbles are uniform, the diameter of the bubbles is about 0.6mm, the hole spacing is about 11mm, and the porosity is about 1.4%. The material removal rate is 181...
Embodiment 3
[0019] The room temperature is 15°C and the relative air humidity is 50%. 23 parts by mass of unsaturated polyester resin (307-3) and 0.28 parts of cobalt naphthenate, 21 parts of aluminum sulfate, 3.98 parts of sodium acetate trihydrate and 0.02 parts of dodecahydrate Sodium hydrogen phosphate was mixed and stirred in a plastic bucket for 6 minutes, and the speed of the mixer was 750r / min. After stirring evenly, 48 parts by mass of Fe with a D50 of 1.6 μm were added. 2 o 3 / SiO 2 Abrasive nanocomposite particles, 0.36 parts of cyclohexanone peroxide and 2 parts of washing powder were evenly stirred for 15 minutes. After the reaction was complete and uniformly mixed, poured into a steel mold for curing, and scraped it with a spatula. After curing for 30 minutes, The polishing disc is formed and the bubbles are uniform. The diameter of the bubbles is about 0.8mm, the hole spacing is about 12mm, and the porosity is about 1.3%. The material removal rate is 179nm / min, and the w...
