高密度聚乙烯的过氧化物交联行为及结晶行为研究
Study on Cross-linking Behavior and Crystallization Behavior of Dicumyl Peroxide Crosslinked High-density Polyethylene
摘要
Abstract
.In this paper, the effect of dicumyl peroxide (DCP) content on cross-linking behavior of high density polyethylene (PE-HD) was investigated. The gel fraction of PE-HD increased with increasing DCP content and reached 73. 9 % with a DCP content of 3.0 %, a temperature of 170 ℃, and a reaction time of 30 min. The effect of DCP content on crystallization behavior of PE-HD was studied using differential scanning calorimetry (DSC) and X-ray diffraction (XRD). It showed that with increasing DCP content, the melting point and crystallization temperature decreased, the crystallinity degree and grain size decreased, however, the crystal structure was not affected.关键词
