摘要/Abstract

摘要： 针对电力电网行业对输电杆塔用复合材料的性能要求,开展了两种聚氨酯树脂(聚氨酯改性乙烯基树脂,VPU;双组份聚氨酯,TPU)制备的复合材料的多项性能研究,并与高性能环氧树脂(EP)复合材料进行了性能对比(采用拉挤成型方式制备)。性能评估包括力学性能、电气绝缘性能、耐腐蚀及老化性能以及表面性能等。研究测试结果表明,EP复合材料具有最优的力学、电气性能,但在耐紫外老化和耐烧蚀方面较差,不适合直接作为户外用绝缘材料;而VPU复合材料具有较好的绝缘、防腐、耐老化性能,同时其表面疏水性最好,但其横向性能有待完善;TPU复合材料的综合性能相对较好,是制备输、配电杆塔或横担的理想材料。

Abstract: According to the essential requirements on the fiber reinforced polymer materials (FRP) used in the power transmission poles or towers, two kinds of FRP materials based on polyurethane resins (vinyl modified polyurethane resin, VPU & two-component polyurethane, TPU) were studied. Simultaneously, FRP material prepared by high-functional epoxy resin was tested as a comparison (all samples were prepared by pultrusion method). EP-FRP material exhibited the best mechanical and electrical insulation properties, but its UV aging resistance and the fire resistance properties were limited. Therefore, it cannot be used directly in the outdoor environments. The insulation, corrosion resistance and aging resistance behaviors of VPU-FRP material were good enough. Also, it had the best hydrophobicity. However, the transverse properties of VPU-FRP should be improved further. The combination properties of TPU-FRP materials turned to have better properties, which was the suitable material for the power transmission poles.

Key words: power transmission pole, fiber reinforced polymer (FRP), pultrusion, electric insulation, aging resistance
