PROCESS FOR PRODUCING ARTIFICIAL WOOD

摘要

PURPOSE: Provided is a process for producing artificial wood, which is excellent in tensile strength, impact strength and water resistance, and is applicable for in interior and exterior materials for building materials. CONSTITUTION: The process comprises the steps of: i) injecting 1-4wt% of one more coupling agent selected from maleic anhydride, phthalic anhydride and silane(3-methylacryloxypropyl trimethoxy silane), into wood meal and adding an initiator to the mixture, followed by treating the surface of the wood meal while stirring; ii) mixing 10-40wt% of one more resin selected from low-density-linear polyethylene, low-density polyethylene, high-density polyethylene, polypropylene and PVC, with the wood meal; and then iii) injecting the mixture into a mold and pressure-molding it to make a composite at 130-180deg.C for 5-30min under a pressure of 2.5-5.0MPa.
