MANUFACTURING METHOD OF SHAPE RETENTION SHEET AND SHAPE RETENTION SHEET

摘要

PROBLEM TO BE SOLVED: To stabilize finish shape of a whole sheet by maintaining a shape of an inner metal layer.SOLUTION: The invention relates to a manufacturing method of a shape retention sheet capable of deforming a predetermined shape and retaining the shape including an elastic body layer forming step (Step S100) for forming an elastic body layer 2 constituted by a rubbery elastic body, an adhesive layer forming step (Step S200) for forming an adhesive layer 3 on at least one layer of the elastic body layer 2 and a tin layer 4 having the tin percentage content of 98 mass%, a tin layer attaching step (Step S300) for attaching the elastic body layer 2 and the tin layer 4 via the adhesive layer 3 at a pressure lower than ambient pressure and an adhesive layer solidification step (Step S400) for solidifying the adhesive layer 3 and a shape retention sheet 1.SELECTED DRAWING: Figure 2
