Embodiment 1

[0116] (production of decorative sheets)

[0117] Using the gravure printing method, on a resin sheet made of colored polyethylene film with a thickness of 60 μm, acrylic-polyurethane resin (formed by adding 5 parts by weight of hexamethylene diisocyanate to 100 parts by weight of acrylic polyol) resin) dissolved in a mixed solvent of methyl ethyl ketone and butyl acetate so that the solid content was 2 g / m 2 , forming an undercoat layer for printing.

[0118] On the primer layer for printing, a gravure printing method using 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) as printing ink, A 4 μm wood grain pattern pattern layer was formed.

[0119] Using the gravure printing method, the solution of polyurethane-cellulose resin is coated on the surface of the above-mentioned resin sheet opposite to the pattern layer, so that the solid content is 2g / m 2 , forming the backs...

Embodiment 2

[0133] A floor decorative material was produced in the same manner as in Example 1, except that a colored polypropylene film having a thickness of 60 μm was used instead of the resin sheet.

[0134] Then, the surface strength of the decorative material for floors was measured by the method similar to Example 1. The surface hardness of the obtained floor finishing material was 59.

Abstract

The present invention provides a floor decorating material which not only has caster resistance but also has excellent cullet cut resistance, impact resistance and walking effect. The floor decorating material can be stably produced with a large amount. The floor decorating material is composed through stacking decorating sheets on wood substrate. The surface hardness is lower than 60 when a D type sclerometer is used for measuring from one side of decorating sheet according to the prescription of JIS K 6253.

Description

technical field [0001] The present invention relates to decorative materials for floors. Background technique [0002] Conventionally, as flooring materials for houses, apartments, etc., for example, wood substrates such as willow plywood with a thickness of about 6 to 15 mm are widely used, and natural wood is cut into thicknesses ranging from several hundred μm to several mm. Panels (protruded panels), materials that are then painted on the surface of the panels. This kind of flooring material that is painted on natural wood can obtain a deep and smooth finish by repeated painting, grinding, and painting, and a beautiful design with a very rich finish can be obtained. [0003] However, it is difficult to stably mass-produce flooring materials using natural wood from the viewpoint of the current scarcity of global wood resources. [0004] In view of such problems, it has been proposed to obtain a flooring material by laminating a decorative sheet whose appearance is simil...
