Description

一种耐低温聚丙烯薄膜材料
技术领域
本发明涉及高分子材料领域，具体是一种耐低温聚丙烯薄膜材料。
背景技术
随着工业的不断发展，高分子材料广泛应用，各个领域对材料性能的要求不断提升。为了满足应用的需要，单纯纯树脂制成的材料显得力不从心，所以，高分子材料领域必须推陈出新，塑料改性的研究也就越来越重要，例如期望聚合物材料耐高温、易于加工成型、具有很好的韧性、较高的强度、性能良好而且价格低廉等等。单一的均聚物材料往往难以满足上述要求，因此可以通过纳米复合技术对现有聚合物材料进行改性，可以制成综合性能优异的新型高分子材料，已成为新材料开发领域的重要研究方向，具有广阔的市场开发应用前景。
聚丙烯(PP)是一种工业产量较大的聚合物，它具有质轻、易于加工、化学稳定性良好等优点，在电子产品、汽车零件、包装材料等领域的应用十分广泛，但PP的耐候性和低温韧性不高，使其在某些方面的应用受到了限制。因此它具有优异的电绝缘性，化学稳定性。由于聚丙烯具有优良的性能，其膜目前已被大量用于电池工业、水处理、空气净化等领域。但它无光泽，在低温下易脆化及破裂，易被各种有害细菌污染。在合适的温湿条件下，极易繁殖细菌。
发明内容
