BRIEF DESCRIPTION OF THE DRAWINGS

[0023] FIG. 1 is an overall structural schematic diagram of the first specific embodiment of the invention;

[0024] FIG. 2 is an overall structural schematic diagram of the second specific embodiment of the invention; and

[0025] FIG. 3 is a structural schematic diagram of the metal core of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0026] In order to further understand the invention, the invention will be further described in detail in conjunction with examples and drawings, and the examples are only used to explain the invention, and do not constitute limitation on the protection scope of the invention.

[0027] Referring to FIGS. 1 and 3, in Example 1 the invention discloses an outdoor flooring, including a metal core 1 and a basal layer 2, wherein said metal core 1 is disposed within the basal layer 2. The metal core 1 is generally made of common metal materials such as iron, aluminum or alloy, normally set to be a planar structure or similar to a planar structure, and mainly plays a supporting role, and the cross section employed in this Example is a zigzag structure. The metal core 1 can also be provided with a punched hole 11.

[0028] The raw materials for preparing the basal layer 2 described above include plastic, auxiliary agent and bulking agent, the plastic is any one of PE, PVC or PS, the bulking agent employed in this Example is the mixture of both wood flour and calcium carbonate, and can also be a certain substance alone, and the bulking agent is the auxiliary agent commonly used in current plastic production process, such as lubricant, and is also well-known to those skilled in the art.

[0029] In order to further optimize the design scheme, the outdoor flooring in this Example also includes a surface layer 3, and the surface layer 3 covers the basal layer 2, can enwrap the whole basal layer 2, or can only enwrap one surface of the basal layer 2, and only enwraps the upper surface of the basal layer 2 alone in this Example. The raw materials for preparing the surface layer 3 mainly include any one of elastomeric material or ASA, said elastomeric material includes any one or mixture of more of flexible PVC, rubber, TPE or TPU, produces an excellent anti-skidding effect, and in this Example is mainly made from flexible PVC and rubber.

[0030] In order to further optimize the design scheme, the surface layer 3 is provided with noctilucent stripes 5 thereon, which mainly plays an indicating role in the night; raw materials for preparing the noctilucent stripes 5 are mainly noctilucent powder, of course pigment can also be added into the noctilucent powder to prepare a mixture, the pigment can be fluorescent pigment, and in this way color can change. The surface layer 3 can also be provided with embossed patterns thereon, which produces a beautiful effect. Of course, shapes of the noctilucent stripes 5 and the embossed patterns are not restricted, and in this Example, said noctilucent stripes 5 are lines provided on both sides of the surface layer 3. The whole lateral surface of the outdoor flooring is provided with a connecting groove.

Example 2

Outdoor Flooring

[0031] Referring to FIG. 2, this Example 2 has a basic structure same as in Example 1, including a metal core 1, a basal layer 2 and a surface layer 3, and the only difference is that the surface layer 3 covers the upper surface and the lateral surface of the basal layer, and no connecting groove is provided on the lateral part of the basal layer 2.

Example 3

The Method of Manufacturing the Outdoor Flooring in Example 1 Described Above, Comprises the Following Steps:

[0032] (1) preparing a metal core such that its cross section has a zigzag structure, and punching holes in the metal core;

[0033] (2) formulating the raw materials of the basal layer by utilizing a mixture of PVC, auxiliary agent, calcium carbonate and wood flour, formulating the raw materials of the surface layer by utilizing flexible PVC and rubber, and adding noctilucent powder and fluorescent pigment into the raw materials of the surface layer;

[0034] (3) mixing the raw materials of the basal layer and the raw materials of the surface layer described above by utilizing a mixer;

[0035] (4) placing the metal core in a mould, extruding the raw materials of the basal layer and the raw materials of the surface layer described above by a plastic extruder, and cooling down to shape on the mould with the metal core placed thereon;

[0036] (5) cutting into a proper size as required; and

[0037] (6) embossing on the surface layer by an embosser.

[0038] The extruder, mixer and embosser described above are machines routinely used in the art, and are well-known to those skilled in the art.

[0039] Facts proved that the outdoor flooring prepared in above examples is durable in use, has greatly improved slip resistance than common outdoor flooring, is almost not deformed, and has better compression resistance than common co-extruded flooring.

[0040] The foregoing is only preferred examples of the invention, and not used to limit the invention, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the invention shall be included within the protection scope of the invention.
