High-density polyethylene(HDPE)is widely used in various fields such as building materials,electrical products,packaging materials,and industrial agriculture.However,HDPE has poor aging resistance,and under the action of thermal oxygen,its mechanical properties may deteriorate.During outdoor use,it is prone to yellowing,embrittlement,and even loss of mechanical properties under the influence of atmospheric and ultraviolet light.In order to broaden the application field of HDPE and provide it with longer service life and comprehensive performance in harsh environments,a composite stabilizer masterbatch is processed through additive blending to achieve comprehensive improvement of HDPE photothermal stability,providing reference for the preparation of HDPE materials with excellent aging resistance.
