Description

  The present invention relates to a directly pasting floor material and a wooden floor using the floor material.

  A flooring material for direct attachment in which a buffer material layer made of a nonwoven fabric or foamed resin is laminated on the back surface of a wood base material such as a plywood or a wood fiber board is known. By directly laying multiple flooring materials directly on the concrete slab, which is the base of the floor, or by laying them through the particle board or plywood (discarded plywood) pasted on the concrete slab, it is made a wooden floor . When constructing a wooden floor, an adhesive or a double-sided pressure-sensitive adhesive tape is usually used for the work of laying and fixing a directly pasting floor material on the floor base.

  When a part of the wooden floor surface is scratched, or when part of the surface is discolored due to changes over time, all or part of the direct-attached floor material that constitutes the wooden floor may be replaced. Desired. However, it is not easy to peel off and remove the flooring material directly attached to the floor substrate using an adhesive or a double-sided adhesive tape from the floor substrate, requiring a long working time. Moreover, since a part of the buffer material layer which is an adhesive bond layer, a nonwoven fabric, or a foamed resin remains on the floor base surface after peeling, the operation | work which removes it is also required.

  As a flooring for solving such inconvenience, Patent Document 1 includes a base material and a foam layer laminated on the base material, and the foam layer is made of an acrylic polymer having adsorptivity. The adsorptive flooring material is described, and since it does not use an adhesive or a double-sided adhesive tape for construction, it is described that it can be easily and quickly detached from the floor base.

As a specific example, the surface smoothing treatment layer is applied to a coating film made of a resin paint applied to a floor ground surface or a floor ground surface. The attached resin sheet can be used. In addition, by forming such a surface smoothing treatment layer, moisture from the floor base can be blocked, and the direct-attached flooring material placed on the wooden floor can be prevented from inadvertently expanding and contracting. . Thereby, the flatness of the wooden floor can be maintained for a long time.

  In the present invention, the acrylic resin forming the acrylic resin layer means a general resin made of a polymer compound having an acrylic group, and representative examples thereof include polyacrylic acid and esters thereof (and polymethacrylic acid). Acid and its ester). Among them, since it exhibits good flexibility at room temperature, has bending durability, and excellent weather resistance, a multilayer structure polymer, that is, two or more acrylic polymers have a core-shell type multilayer structure. An acrylic soft resin which is a polymer being formed is preferred.
