Problems solved by technology

Specifically, if the wooden substrate is too soft, even if the surface coating hardness of the decorative sheet is increased, dents are likely to occur without change. In addition, if the wooden substrate is too hard, the load will be concentrated on the surface of the decorative sheet The coating film is prone to whitening damage regardless of the physical properties of the surface coating film

Embodiment 1

[0083] A primer layer was provided on the back of a 60 μm thick colored polypropylene film (substrate sheet). Next, a pattern layer is formed on the surface of the base material sheet by printing, and an adhesive layer is formed on the pattern printed layer. A transparent polypropylene-based resin sheet having a thickness of 80 μm was laminated on the adhesive layer by extrusion lamination. A base layer is formed by applying a corona discharge treatment to the surface of a transparent polypropylene resin, and then applying a two-component curing polyurethane resin.

[0084] The surface is coated with an ionizing radiation-curable resin with the following composition as a main component to 15 μm by a roll coating method, and then irradiated with electron beams at an accelerating voltage of 175 keV and 5 Mrad using an electron beam irradiation device in an environment with an oxygen concentration of 200 ppm or less. , to make it solidify, thereby forming a surface protection la...

Embodiment 2～9 and comparative example 2～11

[0097] By adjusting the content of each oligomer in Example 1 and Comparative Example 1 or changing the structure of each layer, decorative materials for floors as shown in Tables 1 to 4 were produced.

Abstract

The present invention provides a decorative material for floors which, even when an excessive load is applied thereto in daily lives (for example, when heavy furniture or a desk is dragged), is inhibited from suffering blushing or dents. This decorative material for floors specifically comprises a woody base and a decorative sheet laminated thereto, and is characterized in that (1) the decorative sheet includes a surface protective layer as an outermost layer, the surface protective layer having a thickness of 12-50 [mu]m and a Martens hardness of 50-150 N / mm2, and (2) the woody base comprises one or more woody layers, the woody layer which is in contact with the decorative sheet having a maximum density of 0.8-1.2 g / cm3 and an average density of 0.7 g / cm3 or higher.

Description

[0001] This case is filed on March 27, 2012 , the application number is 201280013765.8 (PCT / JP2012 / 057922) , the name of the invention is Decorative materials for floors divisional application of the patent application. technical field [0002] The present invention relates to a floor decorative material that suppresses the occurrence of albino flaws and dent flaws even when an excessive load is applied in daily life (for example, when dragging heavy furniture or a table). Background technique [0003] Conventionally, decorative sheets having various natural wood patterns are known to be laminated on the surface of wooden base materials made of various plywood boards or wood fiber boards as decorative materials for floors of houses (Patent Document 1, etc.). [0004] Even existing decorative materials for floors have damage resistance suitable for daily life, but when heavy furniture or tables are dragged and excessive loads are applied, whitening scratches and dents m...
