摘　　要：丙纶由于聚丙烯材料分子结构的特殊性,老化现象尤为严重。由于聚丙烯主链上有叔碳原子,在热、氧、紫外线等外界因素的作用下,极易发生化学变化,其表现为红外吸收光谱中出现羰基峰,随后生成过氧化物,断裂后形成游离基,这些游离基进一步引起整个大分子链的裂解、支化与交联,使PP失去高分子材料的特征,丧失其使用性能,PP特性粘度下降或熔体流动速率增大。本课题介绍了抗紫外线抗老化实验制备的丙纶长丝,检测实验结果表明,显著增强了丙纶长丝制品对紫外线的抵抗能力,极大地延长了丙纶长丝制品的使用寿命。Due to the special molecular structure of polypropylene materials,the aging phenomenon is particularly serious.Due to the main chain of the polypropylene on the tertiary carbon atom,the external factors such as heat,oxygen and ultraviolet radiation,under the action of chemical changes extremely easily,its performance for the infrared absorption spectrum of carbonyl peak,then generate superoxide,formation of free radicals after fracture,these free radicals to cause the cracking of macromolecular chain,branched and cross-linked,lose PP macromolecule material characteristics,losing its using performance,PP characteristic viscosity decreased or melt flow rate increased.In this paper,polypropylene filament produced by anti-ultraviolet and anti-aging experiments is introduced.The test results show that the polypropylene filament products have significantly enhanced their resistance to ultraviolet light and greatly extended the service life of polypropylene filament products.
