Description

废旧印刷电路板非金属成分增强尼龙6强度
技术领域
本发明涉及废旧印刷电路板回收利用，特别涉及利用废旧印刷电路板非金属成分增强尼龙6强度。
技术背景
尼龙6(聚酰胺-6)作为工程塑料的主要品种之一，它具有弹性好、力学强度高、韧性好、耐磨和自润滑性优良、耐油性和化学稳定性好、易于成型加工等优良的综合性能，因而被广泛应用于汽车、电子电气、机械等领域。但尼龙6在低温和干躁状况下易脆化、抗冲击性能差，大大限制了其应用领域。利用玻璃纤维的高强度来增强尼龙6是常用的增强方法。
废旧印刷电路板是随着电子产品更新换代速度加快而产生的电子废弃物，，具有较高的回收利用价值，对其进行回收利用，既可以节省有限的资源，又可以避免其产生的环境问题。回收得到的金属材料再利用技术已经很成熟，而非金属材料常常被作为垃圾丢弃、焚烧或填埋, 这不仅会造成资源的浪费, 而且还会污染环境。废旧印刷电路板中的非金属大约占总体质量的65%左右，主要是由玻璃纤维增强环氧树脂组成，对其进行表面处理后可用来增强聚合物基材的强度。
发明内容
    本发明要解决的技术方案是：如何利用废旧印刷电路板非金属材料，如何利用废旧金属电路板非金属材料增强尼龙6强度。
本发明所采用的技术方案是：废旧印刷电路板非金属成分增强尼龙6强度，按照如下的步骤进行：
一、把废旧印刷电路版使用粉碎机粉碎分离出非金属粉末；
二、按照CH3CH2OH:H2O=8:2的体积比配制乙醇溶液，KH-550: CH3CH2OH溶液= 4:6的体积比配制硅烷偶联剂溶液；
三、对废旧印刷电路板非金属粉进行表面处理：将配置好的硅烷偶联剂溶液和废旧印刷电路板非金属粉按照KH-550：非金属粉=1.5：100的比例在高速混合机内混合20min，混合好后在烘箱内于80℃干燥2h；
四、按照质量比，尼龙6：经过步骤三非金属粉末：EBS润滑剂=100:0-40:0.8的比例混合后通过双螺杆挤出机进行挤出、造粒，并在烘箱内于80℃干燥12h，通过注塑机注塑，所述的挤出温度范围为200℃-220℃，注塑温度范围为245℃-250℃，注塑压力范围为60MPa -100MPa。 
本发明的有益效果是：避免废旧印刷电路板非金属材料常常被作为垃圾丢弃、焚烧或填埋而污染环境，同时有效利用废旧印刷电路板非金属材料来增强尼龙6的强度。
具体实施方式
对废旧印刷电路板进行粉碎对金属进行回收利用，把剩余的非金属粉碎成粉末状；按照CH3CH2OH:H2O=8:2的体积比配制乙醇溶液，搅拌均匀待用；按照KH-550: CH3CH2OH溶液= 4:6的体积比配制硅烷偶联剂溶液；将混合好的硅烷偶联剂溶液和废旧印刷电路板非金属粉按照KH-550：非金属粉=1.5：100的比例在高速混合机内混合20min，混合好后在烘箱内于80℃干燥2h；按照经过处理的非金属粉末：EBS润滑剂(N,N'-乙撑双硬脂酰胺)=100:30:0.8的比例混合后通过双螺杆挤出机进行挤出、造粒，双螺杆挤出机从料斗到机头各段温度为：200℃、205℃、210℃、215℃、220℃、220℃、215℃、210℃、200℃，并在烘箱内于80℃干燥12h，通过注塑机注塑，注塑机各段温度为245℃、250℃、250℃、245℃，注塑压力范围为60MPa -100MPa。
