Abstract
本发明提供了一种生活饮用水输送用耐高低温抗菌管材，因内外层都以同种聚丙烯原材料为主，可避免复合管材分脱而破坏的现象；外层白色内层灰金色，保留白色外观及塑料本身韧性的情况下又有效改善PP‑R管材本身的透光性，防止细菌滋生；在内层材料中含有高温料，致使产品在高低温中不易变形破裂。在内层材料中含有矿粉，矿粉中含有电气石粉是一种结构特殊的极性结晶体，自身能长期产生电离子，并永久释放空气负离子和远红外线；所以当有水源接入本产品中，借着内层材料释放的负离子、红外线能消除水中余氯、抑制有害细菌的滋生、净化有机、无机化合物和重金属污染，加速水分子运动，并提高水中矿物质含量。
Description
技术领域
本发明涉及高分子材料领域，特别地，涉及一种生活饮用水输送用耐高低温抗菌管材及其制备方法。
背景技术
中国约50％水源受到污染；污染物：有上百种有机化合物、重金属离子进入水源(对于以有机污染为主的微污染，如：农药、环境内分泌干扰物、藻类毒素和重金属污染物等，则不能彻底去除；并存在氟、砷、铁、锰等超标)。
自来水处理工艺主要针对水中细菌、病毒，而有机、无机化合物和重金属无法去除，且仍有极少的残留微生物存在水中，残留微生物会自然快速繁殖一些细菌。用液氯处理后自来水中残留有余氯，进入人体会给健康造成极大破坏，有潜在的致癌危险(美国科学家发现，自来水厂水处理工艺中最为重要的消毒剂氯可与自来水中残留的化合物等反应产生致癌的氯化副产物)。
铝塑复合管：铝层与塑料层，尤其是与交联聚乙烯层的粘结力较弱，使铝塑管在用于热水管道系统时，容易导致分脱而破坏；铝层焊接缝处为薄弱环节，尤其是搭接焊铝塑管，因此液压试验破裂处大多在焊缝线附近；使用寿命短。
PP-R管：材料本身不具备抗菌能力，对细菌、有机化合物、重金属离子起不到处理作用。在过冷和过热的情况中，易变形甚至破裂。全塑管不仅本身加入了大量抗氧剂以防止材料降解，抗氧剂萃取进入管道滞留的水中，容易造成水质污染，而且因为全塑管中没有隔光阻氧的材料，极易孽生微生物而导致水质的二次污染。另外，PP-R管材具有透光性或半透光性，透光就容易滋生细菌。
发明内容
本发明目的在于提供一种生活饮用水输送用耐高低温抗菌管材及其制备方法，以解决技术问题。
一种生活饮用水输送用耐高低温抗菌管材，包括内外两层及表面冷热水标线；
所述的外层材料为聚丙烯加白色色母；
所述的内层材料为聚丙烯、矿粉和金灰色色母；
所述的水标线材料为聚丙烯加红色或绿色色母。
优选的，所述的内层材料中矿粉的比例为0.3-0.8％。
优选的，所述的内层材料中矿粉的比例为0.5％。
优选的，所述的矿粉的主要成分为电气石粉、赭石粉和稀土粉。
优选的，所述的矿粉中，包含以下重量百分比的成分：
电气石粉 4-7％
稀土粉 1-3％
赭石粉 余量。
一种生活饮用水输送用耐高低温抗菌管材的制备方法，包括以下步骤：先将内外两层及表面冷热水标线材料分别经过高温挤出、真空定性、低温冷却、切割包装，然后在使用中直接和同款聚丙烯为原材料生产的配件进行热熔焊接。
本发明具有以下有益效果：
1、本发明的生活饮用水输送用耐高低温抗菌管材，因内外层都以同种聚丙烯原材料为主，可避免复合管材分脱而破坏的现象；外层白色内层灰金色，保留白色外观及塑料本身韧性的情况下又有效改善PP-R管材本身的透光性，防止细菌滋生；
2、在内层材料中含有高温料，致使产品在高低温中不易变形破裂。
3、在内层材料中含有矿粉(电气石粉、赭石粉、稀土粉)等，矿粉中含有电气石粉是一种结构特殊的极性结晶体，自身能长期产生电离子，并永久释放空气负离子和远红外线；所以当有水源接入本产品中，借着内层材料释放的负离子、红外线能消除水中余氯、抑制有害细菌的滋生、净化有机、无机化合物和重金属污染，加速水分子运动，并提高水中矿物质含量。
