Description
技术领域
本发明属于复合管材领域，具体涉及一种水泥复合管及其制备方法。
背景技术
塑料管一般是以合成树脂，也就是聚酯为原料、加入稳定剂、润滑剂、增塑剂等，以“塑”的方法在制管机内经挤压加工而成。由于它具有质轻、耐腐蚀、外形美观、无不良气味、加工容易、施工方便等特点，在建筑工程中获得了越来越广泛的应用。主要用作房屋建筑的自来水供水***配管、排水、排气和排污卫生管、地下排水管***、雨水管以及电线安装配套用的穿线管等。塑料管种类很多，分为热塑性塑料管和热固性塑料管两大类。属于热塑性的有聚氯乙烯管，聚乙烯管，聚丙烯管、聚甲醛管等；属于热固性的有酚塑料管等。
塑料管的主要优点是耐蚀性能好、质量轻、成型方便、加工容易，缺点是强度较低，耐热性差。然而，在某些特殊环境中，尤其是石油化工领域内，现有的塑料管大多不能满足需求。
发明内容
本发明的目的在于针对现有技术的不足，提供一种水泥复合管及其制备方法，通过将水泥包覆在塑料管体的外层，得到满足石油化工领域要求的水泥复合管，使用寿命达50-100年。
为实现上述目的，本发明采用如下技术方案：
一种水泥复合管，包括水泥外层和塑料管体，所述水泥外层的原料按重量份计为：抗海水水泥140-160份、矿渣微粉290-300份、细砂600-680份、胶粘剂80-100份、水150-165份。
进一步地，所述塑料管体为纤维复合管，其原料按重量份计为：聚偏氟乙烯100～120份、丙烯酸树脂30～50份、丁晴橡胶30～50份、甲基乙烯基苯基硅橡胶35~45份、二硫化二苯并噻唑4~8份、N, N-二环己基-2-苯并噻唑次磺酰胺5~7份、聚苯乙烯30～50份、玄武岩纤维20～30份、阻燃剂8～12份、硬化剂2～5份和抗氧剂2～5份。其外直径为30-40cm，管厚5-8cm。
上述水泥复合管的制备方法，包括以下步骤：
（1）将纤维复合管的原料按比例进行混炼后挤出成型，得到塑料管体；
（2）待塑料管体冷却至室温后，按照配比将水泥外层原料进行搅拌均匀得到水泥砂浆，然后将其喷涂包覆在塑料管体的外表面，再在温度为20±2℃、相对湿度大于95%条件下进行养护后得到水泥复合管。
本发明的有益效果在于：本发明的水泥复合管中水泥外层与塑料管体不易脱层，水泥外层可有效地防止塑料管体被腐蚀、减少磨损，同时提高塑料管体的强度，而塑料管体具备良好的耐腐蚀性、抗氧化性、耐高低温性，可用于运输石油、水。
