The mechanical properties and environmental stress cracking resistance of polyethylene blow molding material are crucial for the quality of blow-molded products,affecting the safe long-term use of blow-molded products.Ethylene-butene copolymer blow molding material prepared by using Ziegler-Natta catalyst was used as the base material,the mechanical properties and environmental stress cracking resistance of polyethylene blow molding material were simultaneously improved by blending with ultra-high molecular weight polyethylene,polyethylene wax,calcium stearate,and other additives,reaching the level of imported metallocene ethylene-butene copolymer blow molding material.In terms of environmental stress cracking resistance,it had surpassed the imported metallocene ethylene-butene copolymer blow molding material,and had good compatibility in the blend.
