Example 6:
the difference from the embodiment 5 is that in the process, before the first veneer layer and the second veneer layer are attached, the veneers are subjected to dry steaming pretreatment, the veneers subjected to surface polishing treatment are placed into a steam box, after steam is uniform, the environment humidity in the steam box is ensured to be 86-90%, the temperature is 105-115 ℃, and the pressure is 1-5 kPa; steaming for 1-1.5 h in the environment, then closing a steam device of the steam box, ensuring that the pressure in the steam box is 3-5kPa and the temperature is 70-75 ℃, and maintaining for 30-60 min.
The PVC material is abandoned by improving the raw material of the substrate layer, and the polyolefin is used for replacing the PVC material, so that the PVC material is more environment-friendly. Further through adding glass fiber in the raw materials of substrate layer to improve the intensity of polyolefin raw materials, strengthen the intensity of substrate layer, thereby increased the effect of double-deck wooden cortex, also make the laminating degree between wooden cortex and the substrate layer better. Through further improvement of the structure of the base material layer, the structure is divided into three layers, so that the first base material layer is used as a layer for directly contacting and connecting the base material layer and the veneer, a more ideal connecting effect is provided, and the veneer layer can be stable and cannot tilt; a second base material layer serving as a main body layer of the base material layer and satisfying a function which the base material layer should have; the third substrate layer, as the bottom on floor, provides comparatively ideal balanced effect to, can be effectively waterproof. In the process, the surface of the base material layer is polished and subjected to corona treatment, so that the surface characteristics of the polyolefin biomass composite material are changed, and the bonding between the base material layer and the wood veneer layer is enhanced.
Comparative example 1:
the difference from example 1 is that no glass fiber is added to the substrate layer.
Comparative example 2:
the difference from example 5 is that no grinding and no corona treatment were carried out in the preparation process.
The floor boards obtained in the above examples and comparative examples of the present invention were subjected to performance tests including the test of the heating dimension change rate and the heating warpage degree, and the test criteria and results are shown in table 1.
