AI Technical Summary
Technical Problem
At present, polyethylene pipes have low stiffness and poor creep resistance, making it difficult to meet the requirements of harsh working conditions such as high temperature, deep burial and complex geology.
Method used
A method for preparing high-ring stiffness polyethylene pipe reinforced with basalt fiber is adopted. Basalt fiber is treated with γ-aminopropyltriethoxysilane to form aminobasalt fiber, which is then melt-extruded with modified polysiloxane, dicumyl peroxide, etc. at high temperature to form a composite material to improve rigidity and deformation resistance.
Benefits of technology
It significantly improves the ring stiffness and creep resistance of polyethylene pipes, making them suitable for long-term service under complex working conditions.

Abstract
本发明公开了一种玄武岩纤维增强高环刚度聚乙烯管及其制备方法，该聚乙烯管包括如下原料：高密度聚乙烯100‑120份、改性聚硅氧烷15‑20份、氨基玄武岩纤维15‑25份和过氧化二异丙苯1‑3份，在原料熔融过程中改性聚硅氧烷上的马来酰亚胺在过氧化二异丙苯的作用下，使得改性聚硅氧烷上的马来酰亚胺和高密度聚乙烯分子链接枝，改性聚硅氧烷上的环氧基能够和氨基玄武岩纤维上的氨基反应，玄武岩纤维本身具有高模量，当它与高密度聚乙烯复合后，能在基体中形成刚性的物理骨架，显著提升材料的抗变形能力，改性聚硅氧烷能阻碍分子链在持续载荷下的相对滑移，从微观层面抑制管材的长期变形，增加管材的抗蠕变效果。
