The invention discloses a pipeline, a preparation method thereof and a high-density polyethylene pipeline floating body system, and belongs to the technical field of water floating type photovoltaic power generation. The pipeline is provided with a high-density polyethylene modified material layer; the high-density polyethylene modified material layer is prepared from the following raw materials in parts by weight: 60-80 parts of high-density polyethylene A, 15-25 parts of glass fibers, 5-15 parts of ethylene propylene diene monomer, 2-3 parts of carbon black, 0.5-3 parts of a coupling agent, 0.5-1 part of a dispersing agent, 0.1-1 part of a UV stabilizer and 0.2-0.5 part of an antioxidant. The pipeline can withstand ultraviolet aging, high temperature, severe cold and humid air erosion, and is not easy to age and degrade, long in service life and low in maintenance and replacement cost. The preparation method is simple and feasible. The high-density polyethylene pipeline floating body system comprising the pipeline has the advantages of high ultraviolet resistance, aging degradation resistance, wear resistance, heat and humidity resistance, high strength and long service life.

    本发明公开了一种管道及其制备方法与高密度聚乙烯管道浮体系统,属于水上漂浮式光伏发电技术领域。该管道具有高密度聚乙烯改性料层;按重量份数计,高密度聚乙烯改性料层的制备原料包括:60‑80份高密度聚乙烯A、15‑25份玻璃纤维、5‑15份三元乙丙橡胶、2‑3份炭黑、0.5‑3份偶联剂、0.5‑1份分散剂、0.1‑1份UV稳定剂以及0.2‑0.5份抗氧化剂。该管道能够经受得住紫外老化、高温、严寒及潮湿空气的侵蚀,不易老化降解,使用寿命长,维修更换成本小。其制备方法简单易行。含上述管道的高密度聚乙烯管道浮体系统具有较强的抗紫外性、抗老化降解性、耐磨性和耐湿热性,且具有较高的强度,使用寿命长。
