Description
技术领域
本发明涉及电力管制备技术领域,尤其涉及一种抗冲击MPP电力电缆保护管及其生产工艺。
背景技术
目前,MPP电力电缆保护管广泛应用于市政、电信、电力和电缆的管线工程之中,并且在安装过程中无需进行大面积破坏路面以及土地,使得安装过程更加环保。
但是现有技术中,由于MPP电力电缆管长时间埋填于泥土之中,在外界的泥土受到冲撞时,MPP电力电缆管抗冲击能力不足,容易导致在地底下发生破碎,导致电缆受损,不能达到对电力电缆进行保护的目的。
发明内容
本发明的目的在于提供一种抗冲击MPP电力电缆保护管及其生产工艺,旨在解决现有技术中的由于MPP电力电缆管长时间埋填于泥土之中,在外界的泥土受到冲撞时,MPP电力电缆管抗冲击能力不足,容易导致在地底下发生破碎,导致电缆受损,不能达到对电力电缆进行保护的目的的技术问题。
为实现上述目的,本发明采用的一种抗冲击MPP电力电缆保护管,包括外MPP管、内MPP管、碳纤维层、隔热层、绝缘层、第一麻布层和第二麻布层,所述第一麻布层粘接于所述内MPP管的外表壁,所述碳纤维层粘接于所述第一麻布层的外表壁,所述隔热层粘接于所述碳纤维层的外表壁,所述绝缘层粘接于所述隔热层的外表壁,所述第二麻布层粘接于所述绝缘层的外表壁,所述外MPP管套设于所述第二麻布层的外表壁。
其中,所述外MPP管的内径大于所述内MPP管的外径,且所述外MPP管与所述内MPP管的材质一致。
其中,所述外MPP管包括以下质量组分组成:聚丙烯85wt%~90wt%、纳米氮化硅陶瓷1wt%~2wt%、抗氧剂0.5wt%~1.2wt%、润滑剂2wt%~3wt%、阻燃剂0.2wt%~0.7wt%、玻璃纤维5wt%~6.5wt%和防腐剂1.3wt%~1.6wt%。
其中,所述阻燃剂采用氯化铵、氯化石蜡、十二氯代环癸烷、氯化萘、四溴乙烷、四溴双酚A、十溴二苯醚、四溴邻苯二甲酸酐、氯茵酸酐和六溴环癸烷的一种或多种的组合。
其中,所述抗氧剂采用二苯胺、对苯二胺和二氢喹啉的一种或多种的组合。
本发明还提供一种抗冲击MPP电力电缆保护管的生产工艺,制备如上述所述的一种抗冲击MPP电力电缆保护管,包括如下步骤:
按比例将原料依次放入至熔炼设备之中进行均匀混合熔炼;
将熔炼完毕后的混合物放入至塑料制管机之中,通过挤压和冷却制得所述内MPP管;
在所述内MPP管的外表壁均匀涂抹水性胶水,并将所述第一麻布层与所述内MPP管粘接;
在所述第一麻布层的外表壁均匀涂抹水性胶水,并将所述碳纤维层与所述第一麻布层粘接;
在所述碳纤维层的外表壁均匀涂抹水性胶水,并将所述隔热层与所述碳纤维层粘接;
在所述隔热层的外表壁均匀涂抹水性胶水,并将所述绝缘层与所述隔热层粘接;
在所述绝缘层的外表壁均匀涂抹水性胶水,并将所述第二麻布层与所述绝缘层粘接;
将已经粘接所述第二麻布层的管件通入管材包胶挤出机之中,并且将上述熔炼完毕的混合物放入至所述管材包胶挤出机之中,在所述第二麻布层的外表壁均匀包裹所述混合物,制得所述外MPP管;
冷却后,通过裁切机进行裁切成为所需的长度,至此所述抗冲击MPP电力电缆保护管制备完成。
