Embodiment 1

[0127] Manufactured by the following method figure 1 Decorative layer for the structure shown.

[0128] Using the gravure printing method, on the substrate sheet 5 (the tensile elastic modulus of this sheet alone is 600MPa) that is made up of the colored polypropylene film of 60 μ m thick, coat acrylic-polyurethane resin (in 100 parts by weight of acrylic multi- (resin) solution obtained by adding 5 parts by weight of hexamethylene diisocyanate to alcohol ester so that the solid content is 2 g / m 2 , forming an undercoat layer (not shown) for printing.

[0129] A solution of acrylic-urethane resin (resin obtained by adding 5 parts by weight of hexamethylene diisocyanate to 100 parts by weight of acrylic polyol) was used as printing ink on the printing primer layer (not shown). The gravure printing method is used to form the pattern layer 4 with a 4 μm wood grain pattern.

[0130] Using the gravure printing method, on the surface opposite to the pattern layer 4 of the base sh...

Abstract

A decoration material for the flooring material is provided to execute mass-production work through continuous lamination by easily cutting a decorative layer below 300 micron meters and to secure water resistance by making the decorative layer over 200 micron meters. A decoration material for the flooring material is produced by forming a decorative layer by laminating a synthetic resin layer(7), a base sheet(5), a pattern layer(4), a transparent adhesive layer(3), a transparent resin layer(2), and a transparent surface protection layer(1) in order and then stacking the decorative layer on a wood substrate with bringing the synthetic resin layer into contact with the wood substrate. A tensile modulus of at least one of the base sheet and the transparent resin layer is below 1000MPa in accordance with JIS(Japanese Industrial Standards) K6734. Tensile modulus of the synthetic resin layer is over 1000MPa in accordance with JIS K6734.

Description

technical field [0001] The present invention relates to a decorative material for floor materials. Background technique [0002] Conventionally, polyvinyl chloride resin sheets have been used in many cases as constituent materials of decorative sheets for resin flooring materials. As a manufacturing method of a polyvinyl chloride resin sheet, the method of adding a plasticizer to a polyvinyl chloride resin is mentioned (patent document 1). When using a sheet, there are advantages that the hardness (hard to soft) of the polyvinyl chloride resin sheet can be easily adjusted by adjusting the amount of the plasticizer added, and embossing can be easily performed. [0003] However, polyvinyl chloride resin may emit harmful graphite and chlorine-based gases when incinerated. In recent years, instead of polyvinyl chloride resins, polyolefin-based resins that do not emit chlorine-based gases during incineration have been used. [0004] However, in decorative materials for floor m...
