Description

一种PE波纹管填充母料及其制备方法
技术领域
本发明涉及波纹管填充母料领域，具体涉及一种PE波纹管填充母料及其制备方法。
背景技术
   随着国民经济的发展和城市建设，大口径塑料排水管道替代传统水泥管道，需求日益强劲。但是1 米以上大口径塑料管道的环刚度是亟待解决的难题。为满足工程对管道环刚度的要求，厂家一般采用内衬钢板或者加厚管壁的办法解决，这种办法成本高，工艺复杂。
  　硅钙镁(简称SCM )晶须是一种新型结构的硅酸盐材料, 呈一维单晶体结构, 直径为0. 2 ～ 0. 8μm, 长度为20 ～ 60 μm, 具有极高的力学性能, 其拉伸强度高达1. 2 GPa, 拉伸弹性模量高达32 GPa, 用作塑料的填料具有明显的增强和增刚作用。目前被广泛用作排水管、污水管、地下电缆管、农业排灌管的高密度聚乙烯(HDPE)双壁波纹管是一种外壁呈波纹状、内壁光滑的新颖管材, 与同规格同强度的其它类管材相比具有用料省、刚性高、弯曲性优良, 以及高抗冲、高抗压等特点, 已在相当范围内取代了传统的钢管、铸铁管、水泥管、石棉管和普通塑料管。但是, 目前困扰大口径双壁波纹管的最大问题是环刚度低。现在国产双壁波纹管的最大内径为710 mm, 有关设备厂家正在大力开发口径1 600mm 的生产线, 这对管材材料的性能提出了更高的要求。
发明内容
    本发明的目的在于提供一种PE波纹管填充母料及其制备方法。本发明的填充母料添加到制备波纹管的原料中，加工出的波纹管具有环刚度高、质量轻、抗氧化性强、用料省、施工安装方便和耐高低温性能好等优点。

  （3）将放出的物料在双螺杆挤出机上挤出造粒，挤出各区温度：一区温度（120～145）℃，二区温度（145～155）℃，三区温度（155～165）℃，四区温度（165～175）℃，五区温度（175～185）℃，六七区温度（160～175）℃，主机转速为200～250r/min，出料、挤出后冷却、干燥，切粒，即可。
 所述的一种PE波纹管填充母料，其特征在于：所述的氢化石油树脂为兰州石化生产的牌号为LH100-1的碳五加氢石油树脂。
 所述的一种PE波纹管填充母料，其特征在于：所述的硅钙镁(SCM)晶须由四川绵阳正业新型材料有限公司生产。
有益效果：
本发明的填充母料，在配方中添加有硅钙镁(SCM)晶须，硅钙镁(SCM)晶须与聚乙烯复合能提高波纹管的环刚度，添加的氢化石油树脂提高了波纹管的强度，抗氧剂的添加增加了波纹管的抗氧化性，自制增强剂的加入，大大提高了塑料的拉伸强度、挠曲强度和弹性模量，同时还可以提高热变形温度、尺寸稳定性，减低了大口径波纹管的生产加工成本。添加本发明的母料加工出的波纹管具有环刚度高、质量轻、抗氧化性强、用料省、施工安装方便和耐高低温性能好等优点。
本申请采用ABS高胶粉、硅烷偶联剂对氧化石墨烯改性，增加氧化石墨烯与塑料材料的相容性，起到增强作用，其中在造粒时，氧化石墨烯受到高温作用，也相当于改性，增加了其分散性，提高了与塑料复合稳定性。
