Description

一种聚氯乙烯水管
技术领域
本发明涉及塑料管道制造技术领域，具体来说，涉及一种聚氯乙烯水管。
背景技术
聚氯乙烯（PVC）树脂是一类强极性聚合物，分子间作用力很大，导致PVC的软化温度和熔融温度较高，而且当温度较高时，PVC容易发生脱氯化氢反应，引起PVC树脂的降解。所以现在加工工艺中通常要加入各种稳定剂或者其他助剂，制得各种不同需求的产品，但现在使用的水管存在冲击性较差的缺点。
发明内容
针对相关技术中的上述技术问题，本发明提出一种聚氯乙烯水管，能够提高聚氯乙烯水管的抗冲击性能和电绝缘性能。
为实现上述技术目的，本发明的技术方案是这样实现的：
一种聚氯乙烯水管,其由以下重量份的原料制成：疏松型聚氯乙烯树脂95-100份，丙烯酸酯类抗冲击改性剂3-12份，稳定剂1.5-3份，填充剂8-10份，色料0.6-5份，外润滑剂0.5-3份。
进一步的，所述稳定剂包括三碱式硫酸铅1.0-2.3份和二碱式亚磷酸铅0.5-0.7份。
优选的，疏松型聚氯乙烯树脂98份，丙烯酸酯类抗冲击改性剂12份，三碱式硫酸铅1.8份，二碱式亚磷酸铅0.5份，高岭土8份，钛白粉1.7份，石蜡-硬脂酸钙0.9份。
本发明所述的聚氯乙烯水管的制备方法为：将聚氯乙烯树脂、抗冲击改性剂、稳定剂以及色料按比例混合后放于高速搅拌机中进搅拌越30min，当温度到达110-130℃时，加入填充剂和外润滑剂，继续搅拌约30min，当反应体系温度达到150-170℃时，将混合均匀的物料喂入单螺杆挤出机，控制螺杆转速为70-95rpm。物料在由芯棒和口模之间的环形通道内成型后挤出设备，得到成品聚氯乙烯水管。
本发明的有益效果：
本发明选用内部组织疏松、表面形状不规则的疏松型聚氯乙烯树脂可以快速吸收多种助剂，提高塑化效率；加入抗冲击改性剂提高成型水管的抗冲击性；将三碱式硫酸铅和二碱式亚磷酸铅两种稳定剂联用，提高稳定性的同时增强电绝缘性能；合理调节各种助剂的配比，提高水管的实用性。
具体实施方式
