摘要： The present invention provides a method for manufacturing an imitation wood and is featured by adjusting the temperature of a discharge outlet before or during conveyance of thermoplastic elastomers in a helical section of a screw extruder to be lower than the temperature of a tail end of the helical section, such that the viscosity of the thermoplastic elastomers in the discharge outlet increases and the flow velocity reduces at the outlet during the discharge process at the discharge outlet. Thus, the thermoplastic elastomers flow in a direction opposite to the discharge direction and rub, resulting in marks of back-flow and rubbing. During the process of back-flow and rubbing, the plastics will be pulled and break along the rubber elastomers and become filament-like, thereby generating filaments similar to wood. Then, the foaming blank material is squeezed out of the discharge outlet and is forced into a molding machine to proceed with planarity trimming, and the output material is cooled with a preset cold-bath tank of the molding machine, providing adjustment of different densities of imitation wood, such that the imitation wood produced by the present invention has high simulation of wood.
摘要翻译： 本发明提供了一种仿制木材的制造方法，其特征在于在螺杆挤出机的螺旋部分中的热塑性弹性体输送之前或期间调节排出口的温度，使其低于螺旋挤出机尾端的温度 使得放电出口处的热塑性弹性体的粘度增加，并且在排出口处的排放过程中出口处的流速降低。 因此，热塑性弹性体沿与排出方向相反的方向流动并摩擦，导致回流和摩擦的痕迹。 在回流和摩擦过程中，塑料将被拉伸并沿橡胶弹性体断裂并变成长丝状，从而产生类似于木材的细丝。 然后，将发泡坯料从排出口挤出，并被迫进入成型机进行平面修整，并且用预成型机的冷浴槽冷却输出材料，调节不同密度的 模仿木材，使得本发明生产的仿木材具有高仿木材性。
