Claims (3)

  1. A laying material having a coating layer made of a polymer compound on the surface of a substrate layer, The coating layer has a plurality of openings on its surface and a three-dimensional network of micropores that connect the plurality of openings at least within the coating layer. The plurality of openings and the micropores are formed by chemical or physical methods. Each of the aforementioned openings allows liquid to enter and exit through the micropores. Laying material.
  2. The laying material according to claim 1, characterized in that the micropores are formed by expanding the grain boundaries of the coating layer.

Description

This invention relates to a laying material used on road and floor surfaces. In recent years, the surface of paving materials used for roads and floors has been coated with a layer of polymer compound coating material for waterproofing, stain resistance, and gloss enhancement. Because paving materials with such coated layers are cheaper and easier to manufacture than those with a polished finish, they are widely used (see Patent Documents 1 and 2). Furthermore, resin waxes applied to the surface of paving materials to restore their gloss effect have also been disclosed (see Patent Document 2).

The following describes embodiments of the present invention based on the drawings. <Basic configuration> The basic structure of the present invention will now be described. As shown in Figure 1, the laying material 1 of the present invention has a coating layer 3 made of a polymer compound on the surface (upper surface) of the substrate layer 2. In other words, the laying material 1 is a multilayer structure in which a coating layer 3 (second layer) is laminated by applying or molding a coating material made of a polymer compound to the surface of the substrate layer 2 (first layer) of the laying material 1. In this specification, the lamination direction of the substrate layer 2 and the coating layer 3 is defined as the vertical direction, with one direction on the plane perpendicular to the upper limit direction being defined as the vertical direction, and the directions perpendicular to both this vertical direction and the upper limit direction being defined as the horizontal direction. The substrate layer 2 is the base layer of the laying material 1. For example, it is composed of natural marble, artificial marble, granite, tiles, ceramic tiles, enamel, metal, wood, etc. The coating layer 3 is formed by laminating a coating material made of a polymer compound onto the surface of the substrate layer 2. The coating material is composed of a polymer compound and is, for example, a coating material for road or floor surfaces intended for waterproofing, stain resistance, or gloss effect. The laying material 1 has a continuous, three-dimensional network of micropores 4. Furthermore, multiple openings 5, which serve as entry and exit points for the micropores 4, are formed on the surface of the laying material 1 (coating layer 3). The micropores 4 are spread throughout the laying material 1 in all directions, connecting the openings 5 on the surface of the coating layer 3 within the coating layer 3 and the substrate layer 2. This structure allows liquids such as water to enter and exit through each of the connected openings 5. By providing micropores 4 through which liquids such as water can pass in the paving material 1, the liquid on the surface of the paving material 1 penetrates into the interior of the paving material 1 through the micropores 4 via openings 5 on the surface of the paving material 1. As a result, when a pedestrian walks on the paving material 1 while its surface is wet with liquid, a suction effect is created by the external force (pressure) from the pedestrian's walking and the surface tension of the liquid acting on the liquid that has penetrated into the paving material 1 through the micropores 4. This increases the frictional force between the pedestrian's foot and th
