摘要
研究了Fe_3O_4表面改性悬浮共聚合法制备墨粉的工艺,试验了主要因素对墨粉粒度的影响。结果表明,当St/BA为5:1、搅拌速度为1000rpm、超声分散时间为15min、水油比为7:1、PVA用量为4％和聚合温度为85℃时,制备的墨粉粒径为12～13μm,达到了商用墨粉对粒度的要求。图9,表1,参10。
The technology of preparing toner with surface modification suspension copolymerization was studied. The influences of main factors on the particle size of toner has been investigated. The results show that the toner with particle size about 12-13μm were obtained when the ratio of St to BA is 5,stirring speed is 1 000 rpm, ultrasonic dispersion time is 15 min,the ratio of W to O is 7,the dosage of PVA is 4 % and the polymerization temperature is 85℃. The particle size of polymerized toner can meet with the commercial requirements. 9figs. , 1tab. ,10refs.
