摘 要: 我国对废弃线路板基板的回收主要是采取填埋和焚烧的方法,处理少量废弃基板时有以下几种方法:取代木屑作为雕塑工艺品的填充物;制造隔音板、天花板、花瓶等;作为粉末用于涂料、铺路材料或是塑料制备的填料等;作为增强材料和绝缘胶粘材料重新利用或做阻火剂等。本文设计了一种资源化回收废弃线路板基板的方案:通过添加环氧树脂与固化剂将废弃线路板基板粉碎所得到的玻璃纤维树脂粉末直接模压成型,成型制品可以作为建材销售。综合考虑回收成本与制品性能,得到最佳成型条件,废弃玻璃纤维树脂粉末质量:环氧树脂∶固化剂=10∶1∶1,温度45℃,加热时间3 h.该方法:处理量大、回收成本低、工艺简便、市场前景广阔。
关 键 词: 环境科学技术基础学科;废弃线路板;玻璃纤维;资源化回收利用;模压成型

Abstract: The resource recycling of waste printed wiring board substrate in our country is mainly carried out by the methods of landfill and incineration. The methods of processing waste substrate when the amount is small are as follows: replace the sawdust to be the filling material of sculpture handicraft; make the soundproofing board, ceiling, vase and so on; be used as powder for the coating, paving material or filler for plastic preparation and so on; be reused as the reinforcing material and insulated gluing material or used as the fire retardant chemical. This article designed a method for resource recycling of waste printed wiring board substrate: the glass fiber resin powder obtained by smashing the waste printed wiring board substrate is moulded directly by adding epoxy resin and firming agent, the product can be sold as building material. By a comprehensive consideration of the recycling cost and the product performance, the best shaping condition is obtained, the content of waste glass fiber resin powder: epoxy resin: firming agent is 10∶1∶1, the temperature is 45℃, heating time is 3 h. This method is big treatment capacity, low recycling cost, simple technology and bright market prospects.
