In another preferred embodiment of the invention, the composite floor is formed by sequentially compounding a wood skin layer, a eucalyptus layer, a glass fiber net layer, a eucalyptus layer, a pine layer, a glass fiber net layer, a pine layer and a back plate layer from top to bottom.
It should be noted that the glass fiber net layer, the eucalyptus layer and the pine layer may be replaced or added with different layers, and are not limited to the preferred embodiment.
In order to increase longitudinal and transverse stretching force and prevent the veneer layer from rolling up, the glass fiber net layer is in a grid shape, and kraft paper ropes (paper roll lines) are uniformly distributed in the pine layer.
Preferably, the back plate layer is beech or maple or other bark of the same thickness, and the pine plate is spruce.
The wood skin layer is natural wood skin with a thickness of 0.8-1.2MM, the thickness of the glass fiber net layer is 0.1-0.2MM, the thickness of the eucalyptus plate layer is more than 2.2MM, the pine plate layer is made of pine plate or spruce plate with a thickness of 9-10.5MM, and the thickness of the back plate layer is 06-0.9MM, and the back plate layer is usually beech, maple and other wood. Compared with the existing composite floor, the composite floor is additionally provided with the glass fiber net layers, the longitudinal and transverse stretching forces are increased, the pine board layers are prevented from rolling up, and the glass fiber net layers are arranged into 5-by-5-MM grids. The kraft paper ropes or paper roll lines are penetrated in the middle of the pine board layer every 3-5MM, and the effect is that the manufactured composite floor has overall geothermal resistance, cracking resistance and good stability.
The manufacturing process of the composite floor comprises the following steps:
(1) selecting pine, cutting and forming according to the size, and drying for 7 days;
(2) sawing pine wood into sheet pine wood boards, slotting the pine wood boards by a slotting machine, putting kraft paper ropes, and connecting the pine wood boards to form a pine wood layer;
(3) compounding a glass fiber net layer and a eucalyptus layer on the top surface of the pine layer, and compounding a glass fiber net layer and/or a pine layer and/or a eucalyptus layer on the bottom surface of the pine layer;
(4) carrying out high-temperature hot pressing on the composite board;
(5) and (4) trimming the hot-pressed composite board, and respectively compounding a wood skin layer and a back board layer on the top surface and the bottom surface to obtain a finished product of the composite floor.
The invention has the beneficial effects that: the composite wood floor is reasonable in structural design and formed by compounding the multilayer boards, compared with the existing wood floor, the composite wood floor is additionally provided with the glass fiber net layer, the longitudinal and transverse tensile force of the floor is improved, and the kraft paper rope is threaded in the middle of the pine board layer to prevent the wood board layer from rolling up.
