Embodiment 3

[0074] image 3 is a cross-sectional view of a laminate drawn according to a third embodiment of the present invention. image 3 in, with figure 1 or 2 corresponding parts are marked with the same number.

[0075] The laminated product of the third embodiment is composed of a fiber-reinforced resin layer 11, an elastic layer 12 (laminated on one side of the fiber-reinforced resin), a surface protection layer 23 (laminated on the elastic layer), and a support layer 34 (laminated on the on the other side of the fiber-reinforced resin layer).

[0076] Since the fiber-reinforced resin layer 11 and the elastic layer 12 are similar to those described in the first embodiment, and the surface protection layer 23 is similar to that described in the second embodiment, their descriptions will be omitted below, and the supporting layer 34 will be described in detail.

[0077] The support layer 34 serves to improve the adhesion of the laminate to the substrate. There are several exampl...

[0079] Figure 4 is a schematic cross-sectional structure diagram of a laminated product according to a fourth embodiment of the present invention. Figure 4 in, with figure 1 or 2 corresponding parts are marked with the same number.

[0080] The laminated product described in the fourth embodiment of the present invention consists of a fiber-reinforced resin layer 11, an elastic layer 12 (laminated on one side of the fiber-reinforced resin layer 11), a surface cover layer 23 (laminated on the elastic layer 12 ) and a second elastic layer 45 (of the same or different type as the elastic layer 12, laminated on the other side of the fiber-reinforced resin layer).

[0081] Since the fiber-reinforced resin layer 11, the elastic layer 12, and the surface protective layer 23 are similar to those described in the third embodiment, these compounds will be omitted in the following description.

[0082] Even without the second elastic layer 45, the required dimensional stability of t...

Abstract

A laminated product according to the present invention has a fiber reinforced resin layer, an elastic layer laminated on one surface of the fiber reinforced resin layer, and a surface protection layer laminated on a surface of the elastic layer for protecting the surface of the elastic layer. The fiber reinforced resin layer includes at least two prepreg sheets, each of which is formed by impregnating a thermoplastic resin into continuous reinforcing fibers arrayed in one direction such that the volume ratio of the continuous reinforcing fibers is in the range of 40 to 80%. The prepreg sheets are laminated so as to the array directions of the continuous reinforcing fibers at right angles.

Description

technical field [0001] The present invention relates to a laminated floor tile or laminate, which has excellent dimensional stability, wear resistance and construction performance, and can be used for laying indoor and outdoor floors, wall coverings and road surfaces. Background technique [0002] Generally speaking, flooring materials are based on wood, stone, fiber, resin and rubber, which can be selected and used according to the nature, function and use of the material. Among these materials, resin-based flooring materials are widely used because of mass production. [0003] Typical examples of resin-based chassis materials are polyvinyl chloride resins and polyurethane resins. [0004] Polyvinyl chloride resin is cheap, and has excellent processing ability and design and construction ability, and is widely used in the floors of residences, shops, public service places, and other extensive purposes. However, compared with wood and stone materials, polyvinyl chloride re...
