Description
技术领域
本发明涉及一种报废车辆车内饰回收的方法。
背景技术
国外的处理方法是将非金属件压碎破碎，这样产生了大量的汽车破碎残留混合物，简称ASR，汽车破碎残留物由多种材料构成，这种混合物用现有的方法难以有效回收，国际上提出应用高温分解方法处理报废汽车塑料破碎残留混合物，热解方法是回收处理报废汽车塑料的较好的方法之一，可以热解出气体、液体和热解固体，对热解物作为燃料燃烧回收能量，但该技术正处于实验室研究阶段，工业上控制较为复杂，工业应用较少。
发明内容
本发明提供了一种报废车辆车内饰回收的方法，包括以下步骤：
1)、选出报废汽车的热塑性塑料件，并拣选出热塑性聚丙烯塑料件
2)、对热塑性聚丙烯塑料件破碎，分多次破碎，第一次破碎至10mm以下筛网，第二次破碎至3mm以下，期间去除部分金属漆。
3)、采用铁磁分选分离出铁质金属碎屑和高压静电分选分离出细小的其它金属碎屑和金属漆；
4)、将分选后的热塑性聚丙烯塑料破碎料充分搅拌混合，分2次以上取一定量进行熔融造粒，并注塑成力学性能测试的标准式样，进行性能测量；
5)、依据热塑性聚丙烯塑料破碎料注塑后的性能测量结果，对分选出的塑料颗粒添加改性剂进行改性处理，塑料颗粒和改性剂的质量比为8-10:1；
6)、将经改性处理后的塑料颗粒加入螺杆混炼挤出机，在该挤出机中在温度240℃熔融挤出，制成粒度为2～6mm的热塑性聚丙烯塑料颗粒，在温度60℃干燥0.5小时，冷却后包装、入库备用。
优选的是，还包括：
7)、将前述经改性处理的塑料颗粒加入造粒机造制热塑性聚丙烯塑料颗粒，并包装、入库备用。
优选的是，所述改性剂为50-80份马来酸酐接枝聚乙烯、40-50份六水氯化镁、7-8份偶联剂、8-10份PE蜡、1-7份抗光老化剂、2-5份抗氧化剂、8-10份脂肪醇聚氧乙烯醚。
优选的是，所述的高压静电分选使用双辊电晕放电高压静电分选机，电晕使用丝状电晕电极或针状电晕电极，电压取8kV，接地电极为辊状，其转速控制在50转/分钟。
本发明至少包括以下有益效果：报废车辆车内饰回收的方法变废为宝，且减少了塑料垃圾，具有环保作用，具有系统的回收方法，之后再制造可以用于其他部件，也可以继续制造汽车内饰件和汽车外饰件以及其他汽车构件。
