歪（凹み傷）の発生を防止できる。 In the elastic floor of the present invention constructed as described above, the modulus is increased by mixing fibers between the first elastic layer and the surface finishing layer, and the second layer is made of a polyurethane resin which is given restoring elasticity. Since the elastic layer is interposed, when forming the second elastic layer on the first elastic layer, the polyurethane resin that is the constituent material of the latter is formed between the rubber chip particles of the former. It is possible to prevent the rubber from penetrating into the microscopic voids that degrade the excellent cushioning performance provided by the voids, and also to prevent the occurrence of permanent deformation (denting scratches) due to the load of heavy objects placed on the elastic floor of the present invention. can be prevented.

In the figure, the polyurethane elastic floor of the present invention includes a first elastic layer 1, which is sequentially laminated on a base plate 5 made of any material such as concrete, wood, metal, etc.
It consists of a second elastic layer 2 and a surface finishing layer 3.

とにより構成される。 The first elastic layer 1 is made by spreading a liquid polyurethane resin material mixed with rubber chips 4 at a weight ratio of 1:5 to 1:13 on a base plate 5, based on a polyurethane resin. By curing, the rubber chips 4 are bonded to each other and fine voids 6 are formed between the rubber chips.

成される。 Next, the second elastic layer 2 is formed by spreading a liquid material such as polyurethane resin mixed with short glass fibers 7 to a required thickness on the elastic layer 1, or by spreading it to a desired thickness.
Alternatively, it can be formed by spreading and laying a non-woven mat of entangled short glass fibers on the elastic layer 1, and coating and impregnating the non-woven mat with a liquid polyurethane resin.

と協働して良好な弾力性を発揮する。 As mentioned above, the polyurethane elastic floor according to the present invention includes a first elastic layer 1 made of rubber chips bonded together with a polyurethane resin to form fine voids between the particles, and a surface finishing layer made of a colored polyurethane resin. Since the second elastic layer 2 having rubber elasticity reinforced with short fibers is interposed between the first elastic layer 3 and the second elastic layer 2, the mixing or interposition of the short fibers suppresses the flow of the liquid polyurethane resin. In addition to preventing the resin from penetrating into the fine voids of the elastic layer 1, the modulus of the resin is increased and permanent deformation caused by placing heavy objects is prevented. It fully demonstrates its functions and exhibits good elasticity in cooperation with the second elastic layer mainly made of polyurethane resin and the surface finishing layer.
