本文设计了两种资源化回收废弃线路板基板的方案:一: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;二:采用溶剂法从废弃玻璃纤维树脂粉末中回收较纯净的玻璃纤维,这些较纯净的玻璃纤维可以作为增强材料或建材填料销售。这两种方案的优点是:处理量大、回收成本低、工艺简便、市场前景广阔。
实验得出结论:综合考虑回收成本与制品性能,得到最佳成型条件为:固化剂/环氧树脂=1:1,废弃玻璃纤维质量/环氧树脂/固化剂=10:1:1,温度45℃,加热时间3h.
温度75℃,加热时间22h,硝酸溶液浓度8mol/l,投料比为废弃玻璃纤维质量/硝酸体积=15g:100ml的分解条件较为适宜。

This article designed two kind of resources recyclings to abandon the line board foundation plate the plan: One: Will abandon the glass fiber resin powder direct mould pressing through the increase epoxy resin and the firming agent which the line board foundation plate smashing obtained will arrive to take shape, takes shape the product to be allowed to take the building materials sale; Hundred million uses the solvent extraction from to abandon in the glass fiber resin powder to recycle the purer glass fiber, these purer glass fiber may take the enhancement material or the building materials padding sale. These two kind of plans merit is: The process load big, the recycling cost low, the craft simple, the market prospect is broad .
The experiment draws the conclusion: The synthesis considered the recycling cost and the product performance, obtain best takes shape the condition is: The solidification suppresses epoxy resin =1:1, abandons the glass fiber epoxy resin/solidification to suppress 10:1:1, warm 45 ℃, heats up time 3h .
The temperature 75 ℃, heats up time 22h, nitric acid solution thick 8mol/l, the ratio is abandons glass fiber nitric acid volume =15g:100ml the decomposition condition to be suitable .
