Detailed Description

Exemplary embodiments that embody features and advantages of the present invention will be described in detail in the following description. It is to be understood that the invention is capable of other and different embodiments and its several details are capable of modification without departing from the scope of the invention, and that the description and drawings are to be regarded as illustrative in nature and not as restrictive.

Referring to fig. 1 to 3, the PP film solid wood composite floor provided by this embodiment is a rectangular parallelepiped plate-shaped structure, and a male tenon 4 and a female tenon 5 are arranged around the composite floor. The PP film solid wood composite floor (hereinafter referred to as 'wood floor') sequentially comprises a PP film 1, a buffer layer 2 and a formaldehyde-free plywood 3 from top to bottom, and all the layers are tightly connected in an adhesive mode. Wherein, the buffer layer 2 is a formaldehyde-free high-density fiberboard with a flat and dense surface. The aldehyde-free plywood 3 is formed by gluing a plurality of layers of single boards, and the male tenon 4 and the female tenon 5 are arranged on the side surface of the aldehyde-free plywood 3. The PP film 1 covers the upper surface of the buffer layer 2 and the side surface of the aldehyde-free plywood 3, and the part of the PP film 1 on the buffer layer 2 has a pattern.

According to the scheme, the PP film 1 is used for coating the buffer layer 2 and the aldehyde-free plywood 3, so that a wood structure is effectively prevented from being affected with damp, corroded and abraded, particularly, tenon positions which are easy to mildew and crack are protected, and the service life of the wood floor is greatly prolonged. No aldehyde high density fiberboard and no aldehyde plywood 3 form no aldehyde timber apron through 1 collocation of PP membrane, compare environmental protection more with the timber apron that pastes impregnated paper, and the pattern style on the PP membrane 1 is various moreover, can replace precious timber panel, practices thrift timber resources, and the cost is also lower.

Specifically, the PP film 1 is a film made of POLYPROPYLENE (PP for short). The PP film 1 is environment-friendly and nontoxic, only releases water and carbon dioxide during combustion, has no peculiar smell, does not contain heavy metal harmful substances such as lead, chromium and the like, and also has the advantages of excellent water resistance, moisture resistance, cold resistance, heat resistance, scratch resistance, wear resistance, strong plasticity and the like.

The PP film 1 can be printed with various patterns, so that the PP film also has the characteristics of various designs and colors, and the actually processed texture effect is better than that of melamine impregnated paper and PVC films, and the texture is clearer and closer to the effect of raw wood. Preferably, the pattern of the present embodiment is a wood grain pattern.

In the aspect of thickness, as the PP film 1 has good scratch-proof and wear-resistant performances and gives consideration to good foot feeling, the PP film 1 is thin and has the thickness range of 0.18-0.35 mm. Preferably, the thickness of the PP film 1 of the present embodiment is 0.22 mm.

With continued reference to FIGS. 2 and 3, the density of the aldehyde-free high density fiberboard is more than or equal to 800kg/m³. Preferably, the density of the aldehyde-free high-density fiberboard of the present embodiment is 850kg/m 3. The thin aldehyde-free high-density fiberboard has insufficient strength, and causes the whole thickness of the wood floor to be larger if the thin aldehyde-free high-density fiberboard is thick, so that the suitable thickness range is 2-3 mm, such as 2mm, 2.5mm, 3mm and the like.

Due to the uneven wood fibers on the surface of the veneer, if the PP film 1 is directly adhered to the veneer, the veneer is easy to separate after being used for a period of time. This scheme is through being equipped with a buffer layer 2 between PP membrane 1 and no aldehyde plywood 3, this buffer layer 2 is surfacing, the no aldehyde high density fiberboard of the fine and close stereoplasm of texture for no aldehyde plywood 3 of below also can closely veneer with buffer layer 2, and make PP membrane 1 of top hug closely firmly to laminate on buffer layer 2, avoided PP membrane 1 direct and no aldehyde plywood 3 veneer, greatly improved the effect of pasting of PP membrane 1 on the floor.

In order to ensure the overall physical strength of the wood floor, the thickness of the aldehyde-free plywood 3 is required to be greater than or equal to 13 mm. Referring again to fig. 2 and 3, the aldehyde-free plywood 3 is formed by gluing three single boards, and sequentially comprises the following components from top to bottom: a first veneer 31, a second veneer 32, and a third veneer 33. It is understood that in other embodiments, the single board may be composed of one layer, two layers, four layers, etc.

Further, in order to balance the structure of the aldehyde-free plywood 3, the first single sheet 31 and the third single sheet 33 of the present embodiment have the same thickness. The thickness of the first single plate 31 is 3mm, the thickness of the second single plate 32 is 7mm, and the thickness of the third single plate 33 is 3 mm. The wood fiber grain directions among the first single board 31, the second single board 32 and the third single board 33 are cross grain-parallel grain-cross grain or parallel grain-parallel grain in sequence. Particularly, the first single plate 31 and the second single plate 32 are made of eucalyptus wood which is economical in manufacturing cost and firm in wood, and the third single plate 33 located at the bottommost layer is made of corrosion-resistant and wear-resistant eucalyptus wood.

In the embodiment, the wood floor has excellent adhesive strength, temperature resistance, chemical corrosion resistance and aging resistance, and is environment-friendly and free of formaldehyde.

Still referring to fig. 2 and 3, the male tenons 4 and the female tenons 5 in the embodiment are in a locking type structure, so that the glue amount used in the splicing of the locking type wood floors is very small, the wood floors are more environment-friendly, and the adjacent wood floors are not easily separated after being locked. As shown in fig. 2 and 3, the lower surface of the male tenon 4 is provided with a locking part 41, and the lower surface of the female tenon 5 is provided with a locking groove 51. The outer edge of the male tenon 4 is approximately conical, so that the male tenon 4 can be conveniently inserted into the female tenon 5. It is understood that in other embodiments, the tongue 4 and the groove 5 may be of a flat buckle type.
