技术领域
本发明涉及波纹管填充母料领域，主要是一种聚丙烯埋地波纹管用增韧母料及制备方法。
背景技术
近年来，我国的塑料管道行业得到高速的发展，应用领域不断扩大，已成为国民经济中重要的产业之一，被誉为城市中的血管，越来越受到各级政府和相关部门的关注。同时，国家相关政策引导使得塑料管道得到进一步推广应用。《国家化学建材产业十五计划和2010年发展规划纲要》、建设部《关于发布〈建设部推广应用和限制禁止使用技术〉的公告》(建设部第218号)等相关文件提出了各种塑料管道的应用领域和发展目标。
聚乙烯双壁波纹管依据其优良的性能，更是得到快速发展，由于PE材料的低弹性模量，其承载压力能力相对较低，改用聚丙烯生产双壁波纹管，在相同条件下，具备更高的环刚度，但聚丙烯波纹管韧性不好，冲击强度低。有必要开发一种应用于聚丙烯双壁波纹管的增韧填充材料，来提高双壁波纹管的冲击性能。
发明内容

所述高密度聚乙烯树脂的相对密度为0.946～0.976g/cm3，熔点为130℃。
所述超细无机矿物粉包括片状、球状、立方状和纤维状结构的粉体。
所述超细无机矿物粉包括碳酸钙、滑石粉、高岭土、云母、石墨粉、硅灰石、硅藻土的玻璃纤维的一种或多种的组合。
所述增韧剂是POE、SBS、EPDM、EVA中的一种。
本发明所述的这种聚丙烯埋地波纹管用增韧母料的制备方法，包括以下步骤：1)、原料检验；2)、按重量配比称取原料；3)、利用密炼机进行捏合混炼；4)、通过单螺杆挤出机造粒；5)、冷却、过筛碎末、检验装袋。
所述冷却步骤中通过三级风进行冷却。
本发明的有益效果为：本发明提供的波纹管母料所制备的波纹管材料的环刚度达10以上，压扁变形测试无破裂，综合性能优良，改善了PP波纹管材料冲击性能上的不足。
