Document Type and Number:
Japanese Patent JP6857463
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a floor material which: has a foam resin layer made of a material including vinyl chloride series resin; has sufficient strength and adequate flexibility; and is relatively light in weight.SOLUTION: A method for manufacturing a floor material has a process to form a foam resin layer by molding a resin composition, including at least either one of vinyl chloride series resin or vinyl acetate series resin and thermally expandable micro capsules consisting of outer shells made of nitrile series thermoplastic resin and an inclusion component which is included in the outer shells and evaporates when heated, while heating the resin composition at 150 to 200°C. The nitrile series thermoplastic resin is a polymer of a polymerizable component which contains 45 mass% or more of nitrile series monomers. The thermally expandable micro capsule has inner pressure of 0.7 to 1.7 MPa at 150°C and 1.5 to 3.5 MPa at 200°C.SELECTED DRAWING: None
