Description

一种环保型再生塑料颗粒及其制备方法
技术领域
本发明涉及一种环保型再生塑料颗粒及其制备方法，属于塑料制品领域。
背景技术
塑料这一项发明给人们的生活带来了诸多便利，但是也在一定程度上给环境造成了污染，废旧塑料的回收与开发原生资源相比，成本较低，所以废旧塑料的回收具有十分广阔的市场和潜力。废旧聚乙烯也与日俱增，若不加以应用，浪费资源，又会对环境造成极大的污染。
发明内容
本发明旨在解决上述问题，提供了一种环保型再生塑料颗粒及其制备方法。
它是由以下重量份数的原料组成的：再生塑料18-36份，淀粉8-12份，碳酸钙粉3-5份，石墨烯3-5份，抗氧剂1-3份，光亮剂0.5-1.5份，增塑剂2-4份。
制备方法如下：(1)根据各原料重量分数称取原料；(2)将再生塑料、碳酸钙粉和石墨烯进行粉碎，待用；(3)将步骤(2)所得混合物进行加热至熔融状态，加入淀粉、抗氧剂、光亮剂、增塑剂；(4)将步骤(3)所得混合熔液投入螺杆式注塑机挤出粒料，即制得再生塑料颗粒。
进一步的，所述的所述的废旧塑料为再生EVA、再生PE、再生PVC、再生PP中的至少一种。
进一步的，所述的淀粉为玉米淀粉、土豆淀粉、木薯淀粉中的至少一种。
进一步的，所述的增塑剂是指乙酰柠檬酸三乙酯、磷酸酯、单硬脂酸甘油酯中的至少一种。
本发明采用再生塑料和淀粉，利用了废料，可减小对周围环境的影响。加工工艺简单方便，对机械设备的要求不高，成本低廉，具有良好的经济效益。
