    • PURPOSE: A method for manufacturing polyolefin/clay nano-composite is provided to improve the mechanical property of the polyolefin/clay nano-composite by effectively dispersing nano clay in a polyolefin matrix. CONSTITUTION: A method for manufacturing polyolefin/clay nano-composite includes the following: 20 to 97 weight% of polyolefin, 0.5 to 40 weight% of organic clay, 0 to 80 weight% of compatibilizer are mixed. The mixture is melted and extruded using an extruder. The elongational flow rate of the extruder is 13% or more. The rotational velocity of a screw is between 300 and 1000rpm, and residence time is between 20 and 90secs. The compatibilizer is one or more modified polyolefin resin containing carboxylic or hydroxyl group.
