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 formaldehyde-free wood composite floor provided by this embodiment has a tenon 7 and a mortise 8 around the wood composite floor. The formaldehyde-free solid wood composite floor (hereinafter referred to as 'wood floor') sequentially comprises a surface layer 1, a transition layer 2, a base material layer 3 and a bottom layer 4 from top to bottom, wherein the layers are tightly connected together in an adhesive manner. Wherein, the thickness of surface course 1 is 0.6mm, is equipped with soybean glue film 5 between surface course 1 and transition layer 2. The transition layer 2 is beech veneer. The base material layer 3 is composed of a plurality of single plates. The male tenon 7 and the female tenon 8 are arranged on four sides of the substrate layer 3.
Through being equipped with the beech veneer as transition layer 2 between substrate layer 3 and surface course 1, avoid surface course 1 directly to do the bonding with substrate layer 3, therefore the bottom surface of surface course 1 need not to use tannin to glue, comes bonding surface course 1 and transition layer 2 through the less big bean gum of infiltration ability simultaneously, prevents effectively that the oozing from appearing to glue, has greatly improved the production yield.
Specifically, the surface layer 1 mainly plays a decorative role, has a thickness of 0.6mm, and can be selected from oak veneer, birch veneer, maple veneer, black walnut veneer or hickory veneer with beautiful wood grain patterns.
Referring to fig. 4 and 5, the soybean glue layer 5 is formed by curing a soybean glue adhesive. Wherein, the formaldehyde-free soybean glue is selected from common commercial brand products.
With reference to fig. 4 and 5, the substrate layer 3 of the present embodiment is formed by gluing eight single boards, and includes, from top to bottom, a first single board 31, a second single board 32, a third single board 33, a fourth single board 34, a fifth single board 35, a sixth single board 36, a seventh single board 37, and an eighth single board 38, and each layer is glued by using tannin glue. Particularly, the first veneer 31 to the eighth veneer 38 are all made of eucalyptus wood which is abundant in resource and low in cost. Preferably, the total thickness of the substrate layer 3 is approximately 13mm, so that the produced wood floor has a thick foot feeling.
Referring to fig. 1 and 6 together, when the wood flooring is viewed from the direction a indicated in fig. 1, the wood fiber grain parallel to the long side of the wood flooring is a straight grain, and the wood fiber grain perpendicular to the long side of the wood flooring is a cross grain. The wood fiber grain directions of the first single board 31 to the eighth single board 38 of this embodiment are, in order, straight grain, cross grain, straight grain, and cross grain. By the combination mode of criss-cross wood fiber textures, internal stress in the wood floor can be effectively eliminated, and the wood floor is prevented from deforming and tilting.
Still referring to fig. 4 and 5, the thickness of the bottom layer 4 of the present embodiment is 0.6-0.8 mm, such as 0.6mm, 0.7mm or 0.8 mm. The floor is made of beech veneers. Since the bottom layer 4 is also thinner, in order to avoid the glue penetration phenomenon, the bottom layer 4 and the eighth veneer 38 are also bonded by the soybean glue layer 5.
Referring to fig. 1 and 2, the male tenons 7 include long male tenons disposed on long sides and short male tenons disposed on short sides of the wood flooring, and the female tenons 8 include long female tenons disposed on the other long side and short female tenons disposed on the other short side of the wood flooring. Preferably, the male tenon 7 and the female tenon 8 of the present embodiment are of a snap-lock type structure. But in other embodiments a flat button type structure may be used. As shown in fig. 4 and 5, the lower surface of the male tongue 7 is provided with a locking portion 71, and the lower surface of the female tongue 8 is provided with a locking groove 81. When the male tenon 7 is inserted into the female tenon 8, two adjacent wood floors are difficult to separate due to the buckling action between the male tenon 7 and the female tenon 8.
While the present invention has been described with reference to the exemplary embodiments described above, it is understood that the terms used are words of description and illustration, rather than words of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
