Abstract
本发明涉及一种具有抑制微生物活性的塑料，包括有用于加工包装材料的塑料、纳米氧化锌、纳米氧化钙和氧化硅；所述氧化锌、氧化钙和氧化硅以具有微动力效应的胶体的形式存在。通过在包装材料中加入氧化钙和氧化硅，能够有效的提高包装材料的阻气效果，即减少氧气的通过量，再加上锌离子的杀菌性能，综合提高了包装材料的抑制微生物生长的能力。
Description
技术领域
本发明属于塑料领域，具体是指一种用于包装的具有抑制微生物活性的塑料。
背景技术
食品保质期受限于包装内微生物的滋生，通过适当的手段来提高这些产品的保质期是一个永恒的目标。现技术通常是在无菌条件下进行包装以及向将被包装的产品中加入防腐剂。
而防腐剂的使用对身体的影响受到广泛的怀疑，现有许多厂家都宣称其产品中不使用防腐剂，这种情况下一般要在无菌条件下进行包装，就要求包装材料具有能够隔离微生物的能力，但现使用的包装材料均存在缺陷。
现有技术提出在包装材料中添加具有杀菌性能的银、锡、铜、锌离子来实现包装材料的抑制微生物性能，但由于锡对于人体有害，铜的过量使用也会对身体产生危害，银属于贵金属，会增加包装成本，锌的活性较高，容易老化而影响最终包装材料的质量。
发明内容
本发明的目的是通过在包装材料中加入能够抑制微生物生长的金属离子的改进技术方案，提高包装材料在能够抑制微生物生长的同时，提高包装材料的耐老化性能及包装材料的气密封性能。
本发明是通过以下技术方案实现的：
一种具有抑制微生物活性的塑料，包括有用于加工包装材料的塑料、纳米氧化锌、纳米氧化钙和氧化硅；所述氧化锌、氧化钙和氧化硅以具有微动力效应的胶体的形式存在。
所述氧化锌的浓度为60-65ppm，所述氧化钙和氧化硅的浓度为氧化锌的2—4倍。
所述氧化钙和氧化硅的重量比为1：3。
所述胶体为三甘醇。
本发明的有益效果是：
通过在包装材料中加入氧化钙和氧化硅，能够有效的提高包装材料的阻气效果，即减少氧气的通过量，再加上锌离子的杀菌性能，综合提高了包装材料的抑制微生物生长的能力。
具体实施方式
以下通过实施例来详细说明本发明的技术方案，应当理解的是，以下实施例仅是示例性的，仅能用来解释和说明本发明的技术方案，而不能解释为是对本发明技术方案的限制。
在本发明的各实施例中，塑料为现有技术，不进行详细说明。
一种具有抑制微生物活性的塑料，包括有用于加工包装材料的塑料、纳米氧化锌、纳米氧化钙和氧化硅；所述氧化锌、氧化钙和氧化硅以具有微动力效应的胶体的形式存在。所述氧化钙和氧化硅的重量比为1：3；所述胶体为三甘醇。
所述氧化锌的浓度为60-65ppm，所述氧化钙和氧化硅的浓度为氧化锌的2-4倍。
所述氧化锌、氧化钙和氧化硅胶体在塑料挤压过程中加入到塑料中。
所述氧化锌、氧化钙和氧化硅胶体中还可以加入稳定剂，用于防止金属离子的凝聚，稳定剂主要是聚乙烯吡咯烷酮(PVP)。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改和替换，本发明的范围由所附权利要求及其等同限定。
