摘要
Abstract
In this study,high-density polyethylene was selected as a base resin,and a suitable photoinitiation system was se-lected to prepare ultraviolet(UV)-crosslinked high-density polyethylene(PE-Xe).The formula was optimized and the pro-cess was explored.The penetration of ultraviolet light was systematically tested.At the same time,the effects of the amounts of photosensitizer and crosslinker,the power of UV lamp,and line velocity on the crosslinking degree of the PE-Xe materials were studied.The results indicated that the penetration ability of ultraviolet light reached 9.5 mm.When the addition amounts of photosensitizer and crosslinking agent was 0.7 wt%,and the UV lamp power was 500 W,the crosslink-ing degree of the PE-Xe material reached over 75%.The prepared pipe exhibited good pressure resistance,excellent me-chanical properties,and a crystalline degree of over 40%,and its oxidation induction time at 200℃was greater than 20 min.关键词
