Nowadays, HDPE water pipe has been used in massive quantities, which brings many conveniences to human beings but also raises problem of susceptible to bacterial contamination. Thus, we described a simple and feasible way to design cost-efficient and antibacterial HDPE pipes with excellent mechanical properties. A basalt fiber (BF) and silver ion glass microbead (AgGB) were coupled by 3-aminopropyl triethoxysilane to form a compound antibacterial agent. Then, the obtained AgGB@BF was melt-mixed with HDPE to produce antibacterial composite. By means of BF surface modification, the AgGB dispersivity in HDPE matrix was obviously improved. The adding of AgGB@BF would simultaneously increase the thermal decomposition temperature and crystallinity of HDPE composites. And, the crystallinity of HDPE could reach the maximum value of 66.3% under a high-pressure condition. The mechanical strength of resultant HDPE composite increased from 17 to 25 MPa. Meanwhile, a long-term and excellent antibacterial property of the HDPE composite was obtained against Escherichia coli. The proposed antibacterial materials can provide a way for designing and preparing eco-friendly and high-performance HDPE pipe products.

银离子玻璃微珠玄武岩纤维复合制备抗菌强化高密度聚乙烯复合材料

如今,HDPE水管被大量使用,给人类带来了诸多便利的同时,也带来了易受细菌污染的问题。因此,我们描述了一种简单可行的方法来设计具有优异机械性能的具有成本效益和抗菌的 HDPE 管道。玄武岩纤维(BF)和银离子玻璃微珠(AgGB)通过3-氨基丙基三乙氧基硅烷偶联形成复合抗菌剂。然后,将获得的 AgGB@BF 与 HDPE 熔融混合以制备抗菌复合材料。通过BF表面改性,AgGB在HDPE基体中的分散性明显提高。AgGB@BF的加入会同时提高HDPE复合材料的热分解温度和结晶度。并且,HDPE的结晶度可以达到最大值66。3% 在高压条件下。所得 HDPE 复合材料的机械强度从 17 MPa 增加到 25 MPa。同时,获得了 HDPE 复合材料的长期和优异的抗菌性能,对大肠杆菌。所提出的抗菌材料可以为设计和制备环保、高性能的 HDPE 管材产品提供一种方法。
