Patent ID: 8012404

Claim:
A method of producing a composition with wooden quality comprising: (A) preparing raw materials for an inner layer according to weight percentages of materials to be included in the inner layer; putting the materials into a blender and blending for 10-15 minutes; cooling the blended materials and storing the materials for later usage; preparing raw materials for an outer envelope according to weight percentages of materials to be included in the outer envelope, including drying wood flour under a temperature of 80-120° C. until a water content of the wood flour decreases to a level lower that 5 wt. %; preparing raw materials for the outer envelope also includes putting the wood flour into a blender and blending the wood flour and other raw materials for the outer envelope for 10-15 minutes; cooling the blended materials, extruding the materials to produce particles, so as to couple the wood flour and the other raw materials for the outer envelope; (B) adding the raw materials of the inner layer into a principal extruder; adding the materials of the outer envelope into an additional extruder; carrying out synchronized extrusion with the two extruders so as to cross link the outer envelope and the inner layer into a single, unitary, and integral body, the single, unitary, and integral body being a semi-final product; (C) cooling down the semi-final product by towing the semi-final product with a drawing machine; and (D) cutting the semi-final product and polishing the semi-final product so as to obtain the composition having wood-like characteristics in appearance and smell.
