本发明系有关于一种偏光板回收方法，该回收方法包含下列步骤：将偏光板经粉碎后，将其浸入化学硷性溶剂中，以将内、外支撑膜层中的碘溶出，接着再经洗净、脱水，并在脱水过程中利用摩擦生热溶解内、外支撑膜层与胶层，使内、外支撑膜层、胶层及偏光本体层分离，最后移去相聚集的偏光本体层的团状物与溶于水中之胶层后，得到最终剩余的内、外支撑膜层，俾使构成偏光板的不同材质部分能被分开收集再利用，达到环保与避免资源浪费之效果。 A method for recycling of polarizers is disclosed herein to comprise the steps of: crushing polarizers and dipping it into basic solvent to dissolve the Iodine of the inner and outer support membrane then washing and dehydrating thereof. The heat generated by a force of friction during the dehydration will dissolve the inner and outer support membrane and the adhesive layer, which make the inner and outer support membrane、 |
