摘要:
 针对废旧印刷电路板处理不当带来的环境污染和资源浪费,本研究使用由两步合成法制备的咪唑类离子液体1-丁基-3甲基咪唑硫酸氢盐([Bmim]HSO4)为处理液,探究[Bmim]HSO4分解电路板的特性,考察温度、加热时间及电路板尺寸大小对电路板分解程度的影响。在温度270℃、加热时间20±2min、电路板尺寸大小为2×2cm2条件时,溴化环氧树脂的溶解程度最大,电路板的分解程度最大;另外,回收的[Bmim]HSO4化学组分基本无变化,可循环使用。电路板经[Bmim]HSO4处理后,铜箔、焊料和玻璃纤维自动分离便于后续的回收,为废旧印刷电路板的无害化处理和资源回收提供了一条新途径。
Abstract:
 Improper treatment about waste printed circuit boards (WPCBs) can cause serious environmental pollution and resources waste. In this study, 1-butyl3-methylimidazolium hydrogen sulfate ([Bmim]HSO4) was synthesized through twostep reaction Separation properties of WPCBs treated by [Bmim]HSO4 was investigated. The influence of treatment temperature, reaction time and particle size of WPCBs on dismantlement of WPCBs were focused. Experimental results indicated that WPCBs can be separated efficiently and nonpolluted. The maximum dissolution of brominated epoxy resin (BER) in WPCBs occurred by controlling the system temperature, heating time, the size of WPCBs at 270℃, 20±2min and 2×2cm2, respectively. The used [Bmim]HSO4 can be recycled. This study offers an effectively way to recycle WPCBs and prevent the environmental pollution of WPCBs.
