WOOD PLASTIC COMPOSITES AND MANUFACTURING METHOD THEREOF |
摘要 |
Disclosed therein are wood plastic composites and a manufacturing method thereof, which can provide a high discoloration resistance by removing lignin from wood flour which is a main material of the wood plastic composites. The method of manufacturing wood plastic composites includes the steps of: removing lignin contained in wood chips through a cooking process of high temperature and pressure; crushing the wood chip from which lignin was removed in order to produce wood flour; putting and mixing polymer resins and additives into the wood flour so as to manufacture mixture of a gel phase; and extrusion-molding, injection-molding or compression-molding the mixture to manufacture wood plastic composites. The wood plastic composites and the manufacturing method thereof can prevent decoloration and after-yellowing even though the wood plastic composites are exposed to UV or moisture for a long time to thereby enhance long-term weather resistance. |
