摘　　要：提出1种聚合物表面微结构平板热压印连续成型方法,该方法是将聚合物基片从挤出机挤出后,通过两辊对基片进行初步压平定型,再利用表面快速加热装置对聚合物表面进行快速加热,使聚合物表面温度迅速高于其熔融温度使其熔融,然后进入联动式平板热压印,设备压印制备出具有表面微结构聚合物片材。该方法的主要特点是将聚合物挤出成型设备和微结构平板热压印设备实现联动,一步法实现平板热压印聚合物表面微结构的连续成型。A continuous polymer microstructure flat embossing process had been proposed, after the polymer substrate came out from the extruder, through the roller pressure on substrate preliminary reel stretch and sizing, then the polymer surface heated rapidly by the rapid surface heating device, improved the temperature of polymer substrate be higher than its glass transition temperature or melting point, then got into the flat embossing mould for printing the surface microstructure of polymer sheet. The main characteristic of this method was realized linkage between the polymer extrusion molding equipment and microstructure flat embossing equipment, made plate the polymer surface microstructure molding became a one-step implementation.
