It is an object of the invention to, it is provided that a kind of water proof type multi-layer composite floor and production method thereof and production method thereof.The present invention has water-proof function, it is possible to efficiently reduce the use of timber resources, more energy-conserving and environment-protective, has higher structural strength and stability in the large simultaneously.
For solving above-mentioned technical problem, technical scheme provided by the invention is as follows: a kind of water proof type multi-layer composite floor, it is characterized in: the upper surface including wood based sheet material layers wood substrate layer is provided with PVC dough cover layer, is provided with polyurethane adhesive layer between described PVC dough cover layer and wood based sheet material layers.
In aforesaid water proof type multi-layer composite floor, the lower surface of described wood based sheet material layers is provided with the EVA bottom of 3mm～5mm.
In aforesaid water proof type multi-layer composite floor, the lower surface of described PVC dough cover layer is provided with multiple V-groove along floor length direction, it is possible not only to increase the bond strength of materials at two layers, and the bulk strength on floor can be improved as stress groove, not only not easily warpage, and load capacity is greatly enhanced.
In aforesaid water proof type multi-layer composite floor, the opening angle of described V-groove is 25～50 °, and the degree of depth is 1.5mm～2.5mm, and the spacing of each V-groove is 12mm～35mm, and maximizing improves bond strength and bulk strength.
In aforesaid water proof type multi-layer composite floor, described wood based sheet material layers is density board, multi-layer sheet or particieboard.
In aforesaid water proof type multi-layer composite floor, the thickness proportion of described PVC dough cover layer and wood based sheet material layers is 1: 3 to 1: 5.
The production method of aforesaid water proof type multi-layer composite floor, specifically includes following steps:
A, in wood based sheet material layers, offer vertical snap close；
B, wood based sheet material layers is carried out surface carbonation, form the carburization zone of 0.2mm～0.3mm；
C, the wood substrate of surface carbonation is placed in polyurethane serosity soak 1～1.5 hour；
D, wood based sheet material layers is taken out from polyurethane serosity, strike off the residual polyurethane of wherein one side, another side viscous pressure PVC dough cover layer；
E, solidification polyurethane.
In the production method of aforesaid water proof type multi-layer composite floor, described PVC dough cover layer is extruded by PVC material.
The production method of aforesaid water proof type multi-layer composite floor, is additionally provided with the step of the one side that EVA bottom hot pressing is not pasted PVC dough cover layer in wood based sheet material layers after described step e.
Compared with prior art, by the present invention in that with PVC as dough cover layer, and use wood based sheet material layers to carry out compound, it is possible to obtain the floor with higher structural strength and stability in the large.The present invention can improve the water resistance on floor, reduces the use of timber, more energy-conserving and environment-protective.And the floor of the present invention is relative to common composite floor board, has higher dimensional stability, the situation of buckling deformation not easily occurs.Additionally the present invention also has waterproof, quiet feature.
In the production method of the present invention, the hole produced after make use of wood substrate carbonization goes to absorb polyurethane, and the substrate layer after solidification can have higher intensity.The method of the present invention, technique is simplified, and has higher production efficiency relative to the processing on Traditional Wood floor.
