Abstract
The invention relates to a method for preparing a polylactic acid (PLA) biodegradable material for lamination and coating, as well as a device thereof. The proposal of the invention is as follows: the PLA biodegradable particles are dried by a drier until the water content reaches a certain standard; the PLA biodegradable particles are heated and melted by a screw conveyor and put into a lamination header by a delivery elbow simultaneously to extrude out a membrane; the lamination machine is pushed to a certain position and the lamination header is located between two rollers of a rolling machine; the displacement of the lamination header left-to-right is controlled by a transverse oil pressure cylinder so as to locate the lamination header at the central position of the two rollers; simultaneously the rolling machine is controlled to lift up and down so as to lift a lamination point between the two rollers to a predetermined distance from a material outlet of the lamination header, therefore, the membrane is laminated or coated on the ground paper or a thin wood paper board to finish quick adhesion more easily so as to provide a paper-made container and achieve the environment-friendly effect of natural degradation.
