Description

塑木混合再生塑料及生产方法
本发明涉及的是以废旧塑料和锯末为原料的再生塑料材料及生产方法。
废旧塑料的回收利用,是将清洗分类后的废旧塑料重新制粒做塑料原料应用,目前只是用这种再生原料直接或与新塑料原料混合生产再生塑料,如生产用于建筑和地下走线用的塑料管等。用废旧塑料生产再生塑料大多是采用单纯一种或不同种类的废旧塑料原料混合制成,未见有用废旧塑料原料与非塑料原料混合生产再生塑料,也未见有用废旧塑料原料与锯末混合的再生塑料制品。
本发明的目的是提供一种生产成本低,重量轻,可满足某些方面使用的塑木混合再生塑料材料及生产方法。
本发明再生塑料材料是通过下述的原料配比及生产方法来实现的;
一、原料组成配比(重量比)包括;用废旧塑料再生而新制造的含单纯一种塑料或者是含不同种类的塑料的塑料材料100份、锯末20-100份、助剂0.1-5份。
二、生产方法;
上述混合物经由一输送装置输送,并不断受到机械混合、捏和及压缩作用,同时沿输送路径受到多级分段加热处理,热处理混合物经由一出料嘴释出成型或进一步处理成型。
本发明使用各种废旧塑料如方便袋、塑料袋、塑料膜、编织袋、塑料废弃物经清洗分类未分类重新制粒的再生塑料原料和锯末为原料生产塑木混合再生塑料材料制品,如生产管材、片材及型材,其生产成本低,重量轻,并具有很好的韧性和刚性,耐腐蚀,可充分满足某些方面应用使用,例如生产用于塑料大栅做拱撑杆的管材或型材等,其结实耐用。
实施例1
原料组成配比(重量比)包括;用废旧塑料再生新制造的含单纯一种塑料或者是不同种类的塑料的塑料材料100份、锯末20份、抗紫外线老化剂2,-羟基-4-甲氧基二苯甲酮(简称UV-9)0.1-0.5份、抗氧老化剂2,2’-二对羟基苯基丙烷(简称双酚A)0.1-0.5份、防腐剂五氯苯酚0.1-0.5份。将上述原料混合后用塑料挤塑机加工成型得制品。
实施例2
原料组成配比(重量比)包括;用废旧塑料再生新制造的含单纯一种塑料或者是不同种类的塑料的塑料材料100份、锯末100份、抗紫外线老化剂2-(2’羟基-3’-丁基-5’-甲苯基)-5-氯苯并三唑(简称UV-326)0.1-0.5份、抗氧老化剂四[3-(3’,5’-二叔丁基-4’-羟基苯基)丙酸]季戊四醇酯(简称1010)0.1-0.5份、炭黑2.0-5.0份。将上述原料混合后用塑料挤塑机加工成型得制品。
本发明含不同种类的废旧塑料再生的塑料材料中聚乙烯或聚氯乙烯塑料的含量最好占60%以上,所含的不同种类的塑料其熔点温度上限相差应≤20℃,这样可使非塑料成份(锯末)的掺入在挤塑加工时可形成较好的均质。助剂根据具体情况加入一种或者是多种。
本发明废旧塑料和锯末在规定的配比范围内配比混合,均可实现获得产品性能较好的塑木混合再生塑料材料制品,锯末含量的高低,对产品的机械性能有一定影响,锯末含量较低时产品韧性相对较高。
