足である。During extrusion or injection molding of a mixture containing a thermoplastic resin such as polyvinyl chloride, polystyrene, ABS and the like and wood flour or a similar cellulosic material, corrosion or internal corrosion of the equipment caused by the treatment occurs. A method for preventing fatigue caused by corrosion, in order to neutralize a gaseous acidic substance generated from a cellulosic substance contained in a mixture, an alkaline substance such as monoethanolamine, triethanolamine, ammonium sulfate, urea or ammonia. Is known to exist (Japanese Patent Publication Sho 52
No. 26534). However, it has been found that when the wood-like molded product produced by this method is left to stand in an outdoor environment, urea is leached onto the surface of the molded product while moisture absorption and natural drying are repeated. The leached urea forms whitish irregular stains on the surface, which significantly impairs the appearance of the molded product. As the thermoplastic resin, polyvinyl chloride, ABS resin and polystyrene are mentioned. However, the strength of the obtained molded product is inferior to that of the particle board, and its use is limited.
In addition, it has poor dimensional stability and is unsatisfactory as a substitute for wooden building materials.
