Technical Field

The invention relates to the technical field of floors, in particular to a cork composite laminated wood floor and a preparation method thereof.

Background

The shortage of wood resources makes small-diameter wood and wood processing residues have very positive significance. The small-diameter wood utilization and inferior wood utilization modes comprise fiber boards, particle boards and laminated wood, compared with fiber boards, particle boards and the like, the laminated wood has the advantages of good water resistance, small deformation, small glue consumption and the like, and in addition, the natural properties of the wood can be retained to a greater extent.

The wooden floor board has the characteristics of returning to the original and the like because of the nature, and occupies a large market in the decorative material. With the improvement of living standard and the change of consumption concept, the demand of personalized and functional floor is continuously increasing. The cork has the advantages of good elasticity, skid resistance, wear resistance, sound absorption, heat insulation and the like, and the cork is processed into the floor to play the roles of vibration absorption, sound absorption and the like, thereby meeting the requirements of falling resistance, skid resistance, sound absorption and the like for protecting old people and children in places such as families, hospitals, libraries and the like.

The existing cork floor is mainly made of pure cork or fiber boards and particle boards which are adhered up and down, and has the problems of insufficient moisture resistance and durability and the like.
