光敏材料添加量对聚乙烯力学性能的影响研究
Effect of the Amount of Photosensitive Material Added on the Mechanical Properties ofPolyethylene
摘要
Abstract
This paper introduces the requirements on mechanical properties of photodegradable plastics in domestic product standards, and carries out the degradation experiment by using the xenon-arc light sources exposure test method. It studies the degradation of the polyethylene plastic bags with different ratio of degradable masterbatch and the mechanical properties of the degradation products. The results show that the tensile strength and the elongation at break are decreased with the increase of the content of the degradation masterbatch. When the addition amount of biodegradable masterbatch is 60%, the breaking elongation retention rate after photodegradation can meet the requirements of the standard and ensure good performance.关键词
