Abstract

The experiments have been performed to obtain zinc complex compound with smaller particle sizes, which is used as a charge control agent in manufacturing toner. Metallic salts and polyhydric alcohols have been studied to investigate their effects on the formation and the triboelectric charge of zinc complex-compound particle with different sizes. Reactants such as zinc chloride and 3,5-di-tert.-butyl salicylic acid have been used to form the complex compound. Polyethylene glycol (PEG-300), glycerin and ethylene glycol have been added into the zinc chloride solution beforehand to lower the reaction rate in the formation of zinc complex-compound. Aluminium(III) chloride has been mixed in the zinc chloride solution beforehand to restrain the particle size from growing. When PEG-300 and aluminium(III) chloride are used to lower the reaction rate and to restrain the particle size from growing, the average particle size of zinc complex compound decreases from $5.28{\mu}m$ to $2.33{\mu}m$, which was 44.1% of $5.28{\mu}m$.

본 연구에서는 프린터 토너의 대전량 제어제로 사용되는 아연 착화합물 제조시 금속염과 다가알코올을 첨가함에 따라 변화되는 입자 형태, 평균 입도 및 마찰대전량에 대해 고찰하였다. 아연 착화합물을 제조하기 위해 염화아연과 3,5-di-tert-butyl salicylic acid를 사용하였다. 다가알코올을 첨가함에 따른 입자 형태 변화를 확인하기 위해 아연 착화합물 제조시 폴리에틸렌 글리콜(PEG-300), 글리세린 및 에틸렌글리콜을 첨가하였고, 금속염인 염화알루미늄을 첨가함으로써 변화되는 입자크기를 확인하였다. 또한 금속염과 다가알코올을 동시에 첨가하여 입도 변화를 확인한 결과, 각각 단독으로 첨가 했을 때보다 아연착화합물의 평균 입도가 더 많이 감소하는 것을 확인할 수 있었다. 특히, 알루미늄 착화합물의 함유량이 30 wt%이고 염화아연에 대한 PEG-300의 몰비를 3으로 하였을 때 아연 착화합물의 평균 입도가 $2.33{\mu}m$로 순수한 아연 착화합물의 평균 입도인 $5.28{\mu}m$의 44.1%로 가장 많이 감소한 것을 알 수 있었다.
