Title:
ジェル前駆体層を有する積層シートの製造方法
Document Type and Number:
Japanese Patent JP6795317
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide means for compensating insufficient strength of a gel precursor and holding the gel precursor in a sheet shape, in a method for producing a laminated sheet formed of a sheet layer and a gel precursor layer provided on the sheet layer.SOLUTION: An extrusion laminate method for laminating a gel precursor layer having weak shape retention and a sheet layer formed from a thermoplastic resin for reinforcing the gel precursor layer is used. Namely, a method for producing a laminated sheet formed of a sheet layer and a gel precursor layer provided on the sheet layer includes sticking a sheet layer formed by extrusion molding a thermoplastic resin to the gel precursor layer before the extrusion-molded thermoplastic resin is solidified.SELECTED DRAWING: None
