Description
技术领域
本实用新型涉及管材技术领域，具体涉及一种过氧化物交联聚乙烯PEX-a管道。
背景技术
PEX由聚乙烯(PE)交联形成，其中，PEX-a由PE采用过氧化物法交联形成得到，交联过程使PE分子间增加了大量的化学键，因而分子的相对位移自由度大大降低，PEX的耐高温能力、低温冲击强度、耐磨性、耐环境应力开裂性、耐化学腐蚀性以及拉伸强度等性能相较于PE均大幅提升。
虽然PEX管具有一系列优良性能，但在实际应用中，水中残余氯、户外光照、氧气渗入等均会大幅度缩短PEX管的使用寿命。如何在这些特殊应用环境下仍然保证管材长期使用寿命是塑料管道企业关注的热点。此外，塑料管道因其抗菌能力较金属管道弱，容易滋生细菌，影响水质。因此，本实用新型旨在发明一种新型过氧化物交联聚乙烯PEX-a管道，增强PEX-a管道的抗老化性能，延长其使用寿命，抑制管道中水中细菌的生长和繁殖，并提高饮用水水质。
实用新型内容
本实用新型的目的在于克服现有技术的不足之处而提供一种过氧化物交联聚乙烯PEX-a管道，该PEX-a管道具有长久可靠的耐压抗老化性能和抑菌性能。
为实现上述目的，本实用新型采取的技术方案如下：
一种过氧化物交联聚乙烯PEX-a管道，由内到外依次粘结有PEX-a抗菌层、PEX-a主体层和抗UV层。该PEX-a管道的外层为抗UV层，有利于增强管道的耐候性，使管道抗老化性能增强，使用寿命延长；管道的内层设为PEX-a抗菌层可以抑制管道中水中细菌的生长和繁殖，并提高饮用水水质。
进一步地，所述PEX-a抗菌层、PEX-a主体层和抗UV层的壁厚比为(1～3)：(9～11)：(0.5～1)，通过控制管材各层的比例，可保证该PEX-a管道具有更长久可靠的耐压抗老化性能，也可以保证其与水接触的内层具有更优良的抑菌性能，提高饮用水水质。
进一步地，所述PEX-a抗菌层的材料为PEX-a和抗菌剂。所述抗菌剂可选用常规的抗菌剂，如无机抗菌剂、有机抗菌剂等。
进一步地，所述PEX-a主体层的材料为PEX-a。
进一步地，所述抗UV层的材料为PE、抗UV助剂和抗氧剂。本实用新型的抗氧剂可选用受阻酚类抗氧剂、亚磷酸酯类抗氧剂、硫醚类抗氧剂等。
与现有技术相比，本实用新型的有益效果为：
本实用新型的过氧化物交联聚乙烯PEX-a管道，由内到外依次粘结有PEX-a抗菌层、PEX-a主体层和抗UV层，其中，抗UV层能够增强管道的耐候性，使管道抗老化性能增强，使用寿命延长；PEX-a抗菌层可以抑制管道中水中细菌的生长和繁殖，并提高饮用水水质。
