Abstract:
A method for making a synthetic wood board, comprising the steps of:a) drying a cellulose crushed material;b) mixing a thermoplastic resin material with said cellulose crushed material to create a mixture;c) kneading the mixture to cause the cellulose crushed material to be surrounded by the resin material to form a gelatinous mixture;d) cooling, pulverizing and regulating the gelatinous mixture to create a synthetic wood meal;e) heating, kneading and squeezing the synthetic wood meal into a molding die to create an extruded material that exits from the die in an extrusion direction;f) feeding the extruded material between a plurality of rollers operatively connected to a brake means such that a control force is applied on the extruded material outside the molding die opposite the extrusion direction to increase the density of the extruded material;g) cutting the extruded material into a suitable length to form the synthetic wood board; andh) forming a wooden grain pattern on a surface of the synthetic wood board.
