Abstract

The invention provides a nano modification high-density polyethylene composite material and a method for preparing the same and relates to the preparation of a high-performance high-density polyethylene composite material. The invention provides the method for preparing the nano particle / high-density polyethylene composite material. According to the technical scheme of the invention, modified nano barium sulfate powder, high-density polyethylene, a double-screw extruder, a granulator and an injection molding machine are adopted. The method is characterized by: fully mixing the modified nano barium sulfate and the dried high-density polyethylene materials in a ratio (the nano particle accounts for 1 to 5 percent of the mass of the high-density polyethylene); adding the mixture to the double-screw extruder at an operating temperature of between 170 and 220 DEG C, a screw speed of between 160 and 220r / min and a charging screw speed of between 30 and 150r / min; extruding the mixture out ofthe extruder after melting and co-blending the mixture, water cooling the obtained product; granulating the product by the granulator; drying the particle, and injection-molding the particle into thenano modification high-density polyethylene composite material by the injection molding machine. The method is applied to the preparation of the nano modification high-density polyethylene composite material.
