Background

The solid wood composite floor is a wood floor formed by alternately laminating plates of different tree species, overcomes the performance problem of the raw materials of the floor by the mutual matching of different tree species, and improves the dimensional stability of the composite floor; meanwhile, the performance requirements on the wood can be reduced by utilizing the effects, so that the wood which cannot meet the requirements originally can be used as the raw material of the composite floor, and the production cost of the composite floor is reduced.

Among various floor raw materials, the white pine has good ecological adaptability, growth capacity and insect resistance, can effectively reduce the raw material cost of the floor when used as the main raw material of the composite floor, has environmental protection value and excellent processing performance, and is a high-quality floor material. However, the white pine is made of cork wood, so that the hardness of the wood is relatively low, and the water content of the white pine is easily influenced by the environment and has large variation range, so that the static bending strength and the elastic modulus of the composite floor can be reduced when the white pine is used as a main raw material; meanwhile, after the composite floor is used for a long time, the composite floor is easy to cause the problems of wet expansion and dry shrinkage due to the change of the water content, so that the floor is warped and deformed. At present, a good method is not provided for solving the problems, so that the white pine cannot be used as a main material of the solid wood composite floor in actual use, and can only be matched with other wood in an auxiliary material mode, and the utilization rate of the white pine is reduced. Therefore, there is a need for a solid composite flooring that can use white pine as a main material and has good moisture content stability and structural strength.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a core three-layer solid wood composite floor. The white pine floor can be used as a main material of the floor and has good water content stability and structural strength.

The technical scheme of the utility model: a core three-layer solid wood composite floor comprises a composite core layer, wherein a surface layer and a back layer are respectively arranged on the front surface and the back surface of the composite core layer, the composite core layer comprises a pine core layer made of white pine, eucalyptus cushion layers are respectively arranged on two sides of the pine core layer, and the thickness ratio of the pine core layer to the single-layer eucalyptus cushion layer is 10: 1-2.

In the core three-layer solid wood composite floor, the surface layer is a log layer, and the thickness of the surface layer is 1-2 mm.

In the core three-layer solid wood composite floor, the material of the pine core layer is canadian white pine, and the thickness of the pine core layer is 8-12 mm.

In the core three-layer solid wood composite floor, the side walls of the composite core layer, the surface layer and the back layer are all wrapped with the wax sealing layers.

In the core three-layer solid wood composite floor, the side walls of the two sides of the eucalyptus wood cushion layer are provided with the bevel openings which are respectively communicated with the surface layer and the back layer, and the wax sealing layer is filled into the bevel openings and is respectively attached to the inner side surfaces of the surface layer and the back layer.

Compared with the prior art, the utility model has the advantages that the eucalyptus cushion layers on the two sides can stabilize the moisture content and improve the strength of the pine core layer through the composite core layer formed by the mutual matching of the pine core layer and the eucalyptus cushion layer, so that the moisture content change and the size change of the pine core layer in actual use are relieved; the back layer made of beech has the characteristics of hard material and strong bearing capacity, and can effectively improve the static bending strength and the elastic modulus of the composite core layer, so that the utility model can reduce the warping deformation after stress, and the flexibility of the pine core layer and the eucalyptus cushion layer can relieve the cracking problem of the back layer, thereby further improving the structural strength of the utility model; through the cooperation of the peripheral wax sealing layer and the bevel opening, the wax sealing layer can effectively relieve external moisture from entering the composite core layer after coating, and the back layer made of beech has high density and good moisture content stability, can reduce the suction of the external moisture and has a relieving effect on the moisture content change of the composite core layer, thereby further improving the integral stabilizing effect of the utility model; through the cooperation, the proportion of the white pine in the composite floor can reach over 58 percent, and all the performances meet the technical standard. Therefore, the utility model discloses have good moisture content stability and structural strength when can regard the white pine as the floor major ingredient.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. A core three-layer solid wood composite floor (a multi-core layer solid wood composite floor) comprises a composite core layer, wherein the front surface and the back surface of the composite core layer are respectively provided with a surface layer 1 and a back layer 2, the composite core layer comprises a pine core layer 3 made of white pine, eucalyptus cushion layers 4 are respectively arranged on two sides of the pine core layer 3, the textures of the adjacent eucalyptus cushion layers 4 and the pine core layer 3 are arranged in a staggered mode in a transverse and longitudinal directions, the thicknesses of the eucalyptus cushion layers 4 on the two sides are the same, and the thickness ratio between the pine core layer 3 and the single-layer eucalyptus cushion layer 4 is 10: 1.7.

The surface layer 1 is a log layer with natural wood grains on the surface, and the thickness of the surface layer 1 is 1.2 mm.

The backing layer 2 is a beech layer and the thickness of the backing layer 2 is 0.4 mm.

The pine core layer 3 is made of Canadian white pine, and the thickness of the pine core layer is 10 mm.

The side walls of the composite core layer, the surface layer 1 and the back layer 2 are all wrapped with wax sealing layers 6.

The side wall all around of both sides eucalyptus bed course 4 is equipped with the bevel connection 5 that communicates surface course 1 and backing layer 2 respectively, seal in wax layer 6 fills to bevel connection 5 and laminate each other with the medial surface of surface course 1 and backing layer 2 respectively.
