在本发明一个较佳实施例中，所述塑料基体包括聚乙烯、聚丙烯、丙烯腈-丁二烯-苯乙烯塑料、聚氯乙烯中的至少一种。
在本发明一个较佳实施例中，所述多元醇为甲基丙二醇和山梨醇以1～2:1～3的质量比混合的混合物。
在本发明一个较佳实施例中，所述磷酸盐为磷酸钙、磷酸锌和磷酸锆以3：2：1的质量比混合的混合物。
在本发明一个较佳实施例中，所述增强纤维包括聚丙烯纤维、石墨纤维和竹纤维，所述增强纤维在塑料基体内形成纤维网。
在本发明一个较佳实施例中，所述聚丙烯纤维、石墨纤维和竹纤维质量比为3～5：2～3：1。
在本发明一个较佳实施例中，所述抗菌剂包括纳米氧化银、纳米氧化铜和甲壳素纤维以2～3：1～2：1的质量比混合的混合物。
在本发明一个较佳实施例中，所述纳米复合填料包括纳米蒙脱土和纳米二氧化硅以任意比例的混合物。
本发明的有益效果是：本发明一种耐久性纳米抗菌塑料，经过合理的原料配比设计，一方面具有优异的抗菌性能，另一方面具有良好的抗菌稳定性，在塑料产品的有效使用期内，抗菌性能仅有轻微下降，其抗菌性能持久，是抗菌塑料的新里程。
