Embodiment 1

[0128] A decorative layer of a stone pattern with a thickness of 2 μm was formed on a colored polypropylene resin film (thickness: 60 μm, color: white) using an ink composition (acrylic urethane) by gravure printing. Next, a transparent polypropylene resin film (thickness: 80 μm) was dry-laminated and installed on the decorative layer using a polyurethane-based dry lamination adhesive. On this transparent polypropylene resin film, by gravure printing, the coating amount is 15g / m 2 Apply an electron beam curable resin composition (acrylate type) to form a coating film, and irradiate electron beams under conditions of 175keV and 5Mrad (50kGy) to crosslink and cure the coating film to form a surface protection layer (thickness: 15μm), A decorative sheet (thickness: 160 μm) was produced.

[0129] Next, prepare a medium-density polyethylene resin sheet (tensile modulus of elasticity: 200 MPa, thickness: 3mm) as a support layer, and dry it in a manner facing the colored polypropyle...

Embodiment 2～5 and comparative example 1～2

[0132] Except having changed into the foamed resin layer and support body layer shown in Table 1 in Example 1, it carried out similarly to Example 1, and produced the decorative material for floors. Table 1 shows the results of evaluation of the obtained floor decorative material.

Abstract

Provided is a decorative material for floor, which has excellent thermal insulation properties, water resistance, moisture-proof properties and shape stability, while having excellent construction easiness and excellent surface characteristics such as impact resistance, load bearing properties and scratch resistance. A decorative material for floor, which sequentially comprises a resin foam layer, a support layer and a decorative layer. The resin foam layer has an expansion ratio of 5-20 times and a compressive modulus of elasticity of 20 MPa or more. The support layer has a tensile modulus of elasticity of 180 MPa or more.

Description

technical field [0001] The present invention relates to decorative materials for floors. Background technique [0002] Conventionally, as flooring materials mainly used for residential use, wooden flooring materials are often used, and wooden flooring materials are generally laminated with wooden materials such as veneer boards, and decorative sheets or coatings are applied thereon. Residential bathrooms, washrooms, kitchens, and other water-using applications are exposed to high humidity. Therefore, wooden floor materials are prone to mold or warp, and resin flooring with excellent moisture resistance is usually used. Cushion floor. However, air-conditioning equipment such as air conditioners are rarely installed in bathrooms, washrooms, etc., and floor mats have problems such as being cold in winter. In order to alleviate the coldness in such winter, it is conceivable to use a foamed flooring material having a foamed layer (for example, Patent Document 1). [0003] prio...
