Description
技术领域
本发明涉及供水管材技术领域，具体为一种抗老化防蚁鼠纳米自洁阻燃的PE管道制备方法。
背景技术
水管是供水的管道，现代装修水管都是采用埋墙式施工，水管的分类有三种，第一类是金属管，如内搪塑料的热镀铸铁管、铜管、不锈钢管等。第二类是塑复金属管，如钢塑复合管，铝塑复合管等。第三类是塑料管，如PB管、PP-R管等。
PE供水管材与传统的金属管和其它塑料管相比，具有密度低、强度与质量比高、脆给温度化低、韧性好、耐腐蚀绝缘性能好、易着色、易于施工和安装等特点、广泛应用于市政和建筑给排水、燃气、供热采暖、电线电缆穿线、农用节水灌溉和工业排污、矿山矿物输送等领域。与钢管相比，成本可降12%左右，工作寿命长，可长达50年（钢管一般为20年），而且维护费用低。在国外的发达国家和地区，PE管是城际埋地供水管道中的占有量已达80%以上，并且国外在PE供水管材方面已经建立起了非常成熟的标准的施工规范。在我国，镀锌管逐步被禁用后，PE管在建筑供水等领域很有竞争优势，在燃气、工业供排水、通讯、农业灌溉等领域，PE供水管材也呈迅速增长的态势。
现有的PE供水管材在使用时深埋在地下，容易被蛇虫鼠蚁啃食，造成管壁的损坏，并且管道内壁长期使用不结垢，严重影响了管道的使用寿命。
发明内容
本发明的目的在于提供一种抗老化防蚁鼠纳米自洁阻燃的PE管道制备方法，以解决上述背景技术中提出的现有的PE供水管材在使用时深埋在地下，容易被蛇虫鼠蚁啃食，造成管壁的损坏，并且管道内壁长期使用不结垢，严重影响了管道的使用寿命的问题。
为实现上述目的，本发明提供如下技术方案：一种抗老化防蚁鼠纳米自洁阻燃的PE管道制备方法，该抗老化防蚁鼠纳米自洁阻燃的PE管道制备方法包括如下步骤：
S1：原料：聚乙烯功能性母粒A：5%、聚乙烯功能性母粒B：5%和聚乙烯混配料95%；
S2：将聚乙烯功能性母粒A加入聚乙烯混配料搅拌均匀后做成管道的外层，将聚乙烯功能性母粒B加入聚乙烯混配料搅拌均匀后做成管道的内层，通过管材成型机挤出一定径一牵引一冷却定型一切割，制成PE供水管材。
优选的，所述聚乙烯功能性母粒A是由总重量的43-45%高密度聚乙烯、1%季戊四醇硬脂酸胺、0.5-1%抗氧剂1010、2-3%氢氧化镁和0.5-0.7%辣椒素混合而成。
优选的，所述聚乙烯功能性母粒A制备方法包括如下步骤：将高密度聚乙烯、季戊四醇硬脂酸胺、抗氧剂1010、氢氧化镁和辣椒素按比例投入高速混合机中在80℃进行搅拌5分钟得到混合原料，将混合原料投入双螺杆挤出机中造粒，得到聚乙烯功能性母粒A。
优选的，所述聚乙烯功能性母粒B是由总重量的94-95%活化改性超细碳酸钙粉体和5-6%复合抗菌剂混合而成。
优选的，所述聚乙烯功能性母粒B的制备方法包括如下步骤：将活化改性超细碳酸钙粉体在加入复合抗菌剂的配方比例投入高速混合机中在80℃进行搅拌5分钟得到混合原料，将混合原料投入双螺杆挤出机中造粒，得到聚乙烯功能性母粒B。
优选的，所述复合抗菌剂是由氧化镧和载锌磷酸锆复配而成。
优选的，所述活化改性超细碳酸钙粉体是由总重量的92-94%超细纳米级碳酸钙、2-3%铝钛复合偶联和1-3%硅烷偶联剂混合而成。
优选的，所述活化改性超细碳酸钙粉体的制备方法包括如下步骤：将超细纳米级碳酸钙、铝钛复合偶联和硅烷偶联剂投入高速混合机中，搅拌加温到100-110℃脱水10-20分钟，制成含水率低于0.8%的活化改性超细碳酸钙粉体。
与现有技术相比，本发明的有益效果是：本发明在管道的材料内添加辣椒素可以对鼠蚁口腔产生灼热感使其对PE管产生厌恶从而保护了PE管不被虫鼠破坏，抗氧剂促进延长管材的抗老化能力，无卤阻燃剂增强了PE管的阻燃功效，延长使用寿命，并增加了管道的安全性，流水的内壁纳米自洁，不结垢，提高了饮水卫生指标。

本发明提供一种抗老化防蚁鼠纳米自洁阻燃的PE管道制备方法，提高使用寿命长，不被鼠蚁损害，阻燃，管道内壁长期使用不结垢，请参阅图1，
该抗老化防蚁鼠纳米自洁阻燃的PE管道制备方法包括如下步骤：
S1：原料：聚乙烯功能性母粒A：5%、聚乙烯功能性母粒B：5%和聚乙烯混配料95%，聚乙烯功能性母粒A是由总重量的43-45%高密度聚乙烯、1%季戊四醇硬脂酸胺、0.5-1%抗氧剂1010、2-3%氢氧化镁和0.5-0.7%辣椒素混合而成，聚乙烯功能性母粒A制备方法包括如下步骤：将高密度聚乙烯、季戊四醇硬脂酸胺、抗氧剂1010、氢氧化镁和辣椒素按比例投入高速混合机中在80℃进行搅拌5分钟得到混合原料，将混合原料投入双螺杆挤出机中造粒，得到聚乙烯功能性母粒A，聚乙烯功能性母粒B是由总重量的94-95%活化改性超细碳酸钙粉体和5-6%复合抗菌剂混合而成，聚乙烯功能性母粒B的制备方法包括如下步骤：将活化改性超细碳酸钙粉体在加入复合抗菌剂的配方比例投入高速混合机中在80℃进行搅拌5分钟得到混合原料，将混合原料投入双螺杆挤出机中造粒，得到聚乙烯功能性母粒B，复合抗菌剂是由氧化镧和载锌磷酸锆复配而成，活化改性超细碳酸钙粉体是由总重量的92-94%超细纳米级碳酸钙、2-3%铝钛复合偶联和1-3%硅烷偶联剂混合而成，活化改性超细碳酸钙粉体的制备方法包括如下步骤：将超细纳米级碳酸钙、铝钛复合偶联和硅烷偶联剂投入高速混合机中，搅拌加温到100-110℃脱水10-20分钟，制成含水率低于0.8%的活化改性超细碳酸钙粉体；
S2：将聚乙烯功能性母粒A加入聚乙烯混配料搅拌均匀后做成管道的外层，将聚乙烯功能性母粒B加入聚乙烯混配料搅拌均匀后做成管道的内层，这样可以完成外层材料具有防蚁鼠抗老化无卤阻燃功能，管道内壁具有纳米自洁功能，通过管材成型机挤出一定径一牵引一冷却定型一切割，制成PE供水管材，在管道的材料内添加辣椒素可以对鼠蚁口腔产生灼热感使其对PE管产生厌恶从而保护了PE管不被虫鼠破坏，抗氧剂促进延长管材的抗老化能力，无卤阻燃剂增强了PE管的阻燃功效，延长使用寿命，并增加了管道的安全性，流水的内壁纳米自洁，不结垢，提高了饮水卫生指标。
经测试，该PE管的拉伸强度为26.8Mpa，断裂伸长率为475%，外观光亮，氧化诱导时间120分钟，管道质量符合GBT13663.2-2018给水用聚乙烯(PE)管道系统第2部分管材的标准。
虽然在上文中已经参考实施例对本发明进行了描述，然而在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，本发明所披露的实施例中的各项特征均可通过任意方式相互结合起来使用，在本说明书中未对这些组合的情况进行穷举性的描述仅仅是出于省略篇幅和节约资源的考虑。因此，本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
