MANUFACTURING METHOD OF A PLASMA-TREATED RICE HUSK/POLYPROPYLENE COMPOUND WITH CONSIDERABLY LOW MOISTURE-ABSORPTION

摘要

PURPOSE: A manufacturing method of a plasma-treated rice husk/polypropylene compound is provided to provide a rice husk/polypropylene compound with a low void content, tensile strength, and tensile modulus.;CONSTITUTION: A manufacturing method of a plasma-treated rice husk/polypropylene compound comprises: a step of sodium hydrogen oxide treating rice husk; a step of supplying a polypropylene fiber into a plasma coating device with a twin screw extruder; a step of generating a rice husk/polypropylene compound by mixing the rice husk and polypropylene fiber in the double screw extruder; and a step of injecting carrier gas and monomer liquid into the plasma coating device and coating the risk husk/polypropylene compound.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) First step of sodium hydrogen oxide treating rice husk supplied from outside; (BB) Second step of supplying polypropylene fiber supplied from the outside into a plasma coating device equipped with a twin screw extruder; (CC) Third step of mixing the rice husk, treated in the first step, and the polypropylene fiber in the twin screw extruder and mixing a RH/PP compound; (DD) Fourth step of plasma coating the RH/PP compound by injecting carrier gas and monomer liquid into the plasma coating device
