Background

At present, in many public buildings, PVC coiled materials are mostly used as surface layer materials for laying floor surfaces, and because the materials have moderate hardness, elasticity and no dust, and also have the functions of sound insulation, skid resistance, heat preservation and the like, the materials are novel light floor decoration materials which are very popular at present, and are widely used in various places such as families, hospitals, schools, office buildings, factories, public places, supermarkets, businesses, stadiums and the like.

However, the existing PVC coiled material also has many disadvantages, for example, the patterns on the surface of the PVC coiled material floor are subjected to surface printing by a transfer printing process, so that the patterns on the surface of the PVC coiled material floor are planar patterns, have no three-dimensional sense, are difficult to convert colors and colors, can only make model changes in a limited range, lack individuality, and have difficulty in meeting the expected requirements of people, and can not meet the market demands of small-batch multi-color only in some specific application occasions. In addition, the hardness and the intensity of PVC coiled material are influenced by technology and equipment, the elasticity is not adjustable, the application range is limited, the hardness requirement of various occasions can not be met, the popularization and the popularization of PVC coiled materials are hindered to a certain extent, particularly, in primary schools, kindergartens, amusement parks and other places, children are more, the children fall down easily in the playing process, the floor of the existing PVC coiled material is poor in elasticity, the children fall down easily, and potential safety hazards exist.

Furthermore, the flooring rolls can only be printed or embossed on the outer surface to form a decorative effect, which easily disappears due to abrasion, and if the decorative effect is embedded inside the rolls, the construction time and drying/curing time involved with the different layer materials are different, resulting in problems of insufficient adhesion and cohesion between the different layer materials.

Therefore, in view of the above-mentioned disadvantages of the prior art, it is necessary to develop a web material which is easy to construct, low in cost, excellent in performance, flexible in design, freely selectable in surface pattern and design, and easy to maintain at a later stage.

In a preferred embodiment, the fibrous texture network sandwich 4 contains a three-dimensional interpenetrating network structure formed by fibers, wherein the fibers comprise horizontal fibers, vertical fibers and fibers in an inclined direction, and the overlook structure of the fibrous texture network sandwich 4 is shown in fig. 2A-2B. Referring to fig. 2A-2B, in the same plane, transverse fibers 55 cross longitudinal fibers 54 and diagonal fibers 53, with the crossing fibers surrounding the mesh 52. The intersections between the fibers are at least partially connected together to form the connection points 51, for example, the connection points 51 may be one or more of welding, chemical bonding, and the like, and in this embodiment, welding is preferred.

The number of fibre junctions may be 1-100% of the number of fibre junctions, i.e. junctions may all form junctions, but also only some junctions may form junctions. As shown in fig. 2A, the intersection between the transverse fiber indicated by the mark 55 and the longitudinal fiber indicated by the mark 54 does not form a connection point, but the intersection between the transverse fiber indicated by the mark 55 and the oblique fiber indicated by the mark 53 and the intersection between the longitudinal fiber indicated by the mark 54 and the oblique fiber indicated by the mark 53 form a connection point 51.

It should be understood that the fibrous texture network sandwich 4 of the present invention is a three-dimensional structure, i.e., the fibers are not all arranged in the same plane, and there are actually horizontal, vertical and oblique fibers, and the horizontal, vertical and oblique fibers cross each other and form at least part of the connection points. In addition, because of the large length of the fibers, each fiber may have a plurality of horizontal portions, vertical portions, and inclined portions, and the plurality of horizontal portions, the plurality of vertical portions, or the plurality of inclined portions may or may not exist in the same horizontal plane, vertical plane, or inclined plane.

As shown in FIG. 3, transverse meshes 22 are formed between the transverse fibers 31 in the upper horizontal plane and the transverse fibers 32 in the lower horizontal plane, and longitudinal meshes 21 are formed between the transverse fibers and the vertical fibers 33 in the vertical plane, and the transverse meshes 22 are communicated with the longitudinal meshes 21. Similarly, the diagonal direction meshes 23 are formed between the transverse fibers 31 and the diagonal direction fibers, and between the vertical fibers 33 and the diagonal direction fibers, respectively, and fig. 3 shows the case where the two diagonal direction meshes 23 are communicated, but the diagonal direction meshes 23 may be communicated with the transverse direction meshes 22 and/or the longitudinal direction meshes 21.

The transverse fibers 31 in the upper horizontal plane and the transverse fibers 32 in the lower horizontal plane may be derived from two horizontal portions of the same fiber, or may be derived from two fibers.

Referring to fig. 2B, in the case of polyethylene fibers, in the process of welding the fibers of the fibrous texture network sandwich 4 in a three-dimensional arrangement by hot pressing, part of the fibers are melted to form a block structure 100, so that when the infiltration and solidification binder 3 and/or the second self-leveling layer 5 are infiltrated and filled into the meshes, the biting force on the fibers can be further increased, and the bonding force of the coating in each coating is enhanced.

Referring to fig. 4, the surface fibers of the fibrous texture network sandwich 4 may be uneven, such as the first portion of fibers 301 is lower than the second portion of fibers 302 in fig. 4, but the surface of the fibrous texture network sandwich 4 may also be flattened by a flattening process; during the curing of the second self-leveling layer 5, the coating on the surface of the fiber is blocked by the fiber to stay on the surface of the fiber, for example, the surface of the first part of the fiber 301 forms a lower texture 501, the surface of the second part of the fiber 302 forms an upper texture 502, and the second self-leveling layer 5 sinks at the mesh 52 to form a concave texture part 503. And the coating of the second self-leveling layer is filled in the sunken texture part to form a chimeric structure.

The second self-leveling layer 5 is coated on the impregnation composite body consisting of the fiber texture network sandwich 4 and the impregnation curing binder 3, so that the surface hardness of the material can be adjusted, the surface of the material has good elasticity, extensibility and water resistance, and the bonding force among coating structures is improved. And the wear-resistant coating 6 is coated on the second self-leveling layer 5 and used for improving the anti-skid and wear-resistant properties of the whole composite structure, so that the material has the functional characteristics of skid resistance, wear resistance, water resistance and the like.
