一种废旧印刷电路板非金属粉增强的废旧ABS基复合材料及其制备方法
摘要：
本发明提供了一种废旧印刷电路板非金属粉增强的废旧ABS基复合材料，包括废旧印刷电路板非金属粉、废旧ABS和尼龙6，废旧印刷电路板非金属粉的重量为废旧印刷电路板非金属粉、废旧ABS和尼龙6总重量的10％‑30％，尼龙6的重量为ABS和尼龙6总重量的10％‑40％。该复合材料的力学性能较好。本发明还提供了该复合材料的制备方法，包括以下步骤：(1)取废旧印刷电路板，将所述印刷电路板进行破碎、分选，得到废旧印刷电路板非金属粉；(2)取废旧ABS颗粒和PA6颗粒，将废旧印刷电路板非金属粉、废旧ABS颗粒和PA6颗粒在加热条件下混合均匀后，挤出成型，加热的温度为180‑250℃，制得废旧印刷电路板非金属粉增强的废旧ABS基复合材料。该制备方法工艺简单，操作方便。
摘要（英）：

The invention provides a waste printed circuit board non-metal powder enhanced waste ABS-based composite material which comprises waste printed circuit board non-metal powder, waste ABS and polyamide 6 (PA 6), wherein the weight of the waste printed circuit board non-metal powder accounts for 10-30% of the total weight of the waste printed circuit board non-metal powder, waste ABS and PA 6; the weight of PA 6 accounts for 10-40% of the total weight of waste ABS and PA 6. The composite material is relatively good in mechanical property. The invention further provides a preparation method of the composite material. The preparation method comprises the following steps: (1) selecting a waste printed circuit board for crushing and sorting, so as to obtain the waste printed circuit board non-metal powder; (2) selecting waste ABS particles and PA 6 particles, uniformly mixing the waste printed circuit board non-metal powder, the waste ABS particles and the PA 6 particles under the heating condition of 180-250 DEG C, and carrying out extrusion molding to prepare the composite material. The preparation method is simple in process and convenient to operate.
