specific Embodiment approach 1

[0009] Specific embodiment 1: The manufacturing method of a wood-plastic composite floor described in this embodiment includes the step a of preparing a wood core; preparing a thermoplastic wood-plastic composite material masterbatch and feeding the wood core through co-extrusion equipment The step b of melting the wood-plastic composite material masterbatch and co-extruding the profile with the wood core; the step c of cutting the profile obtained through step b into floor boards; and the step c of The end faces of the floorboards are closed step d.

[0010] The technical effect of this embodiment is: by feeding the wood core in the co-extrusion equipment and co-extruding the wood-plastic composite material masterbatch and the wood core into a molding material, the wood core replaces a part of wood-plastic to become a structural material, and the processing The strength of the wood-plastic composite floor is improved, and it is suitable for use as a long-span floor, which sol...

specific Embodiment approach 2

[0011] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the wood core processing method described in step a is first to process the two ends of the dried solid wood with a milling head to obtain mutually matched finger-jointed tenons, and then Polyvinyl acetate emulsion, acrylic resin, acrylic-polyurethane resin, isocyanate, melamine-urea-formaldehyde, urea-formaldehyde glue or phenolic glue to process the finger-joint tenons that match each other, and then apply opposite pressure on the two ends of the solid wood to make the solid wood Parallel or end-to-end splicing, the wood core is obtained after the adhesive is cured.

[0012] The technical effect of this embodiment is: by manufacturing mutually matching finger-joint tenons and treating said mutually matching finger-joint tenons with polyvinyl acetate emulsion, melamine-urea-formaldehyde, urea-formaldehyde glue or phenolic glue, the length of the wood core is not affected by t...

specific Embodiment approach 3

[0013] Specific embodiment 3: the difference between this embodiment and specific embodiment 1 is that the wood core processing method described in the step a is, at first select the solid wood rotary-cut veneer, apply polyvinyl acetate emulsion, acrylic resin on the surface of the veneer , acrylic-polyurethane resin, isocyanate, melamine-urea-formaldehyde, urea-formaldehyde glue or phenolic glue, and then according to the texture of the veneer to assemble blanks cross-laminated in the warp and weft directions, and then apply pressure to the blanks and leave it still to obtain laminated boards, Finally, the laminated board is cut to obtain the wood core.

[0014] The technical effect of this embodiment is: by using the method for manufacturing laminated boards to manufacture the wood core, it is beneficial to overcome the inhomogeneity of the mechanical properties of the wood in all directions, so that the prepared wood core is not easy to deform or warp, The internal mechanic...

Abstract

The invention relates to a floor and a manufacturing method thereof, in particular to a wood-plastic composite floor and a manufacturing method thereof. The problem that a wood-plastic floor is low in intensity and high in density, creeping can happen easily, and the wood-plastic floor is not suitable for being used as a large-span floor. The method comprises the steps that a. a wooden core is prepared; b. thermoplasticity wood-plastic composite material parent stock is prepared, the wood-plastic composite material parent stock is subjected to fusion through co-extrusion equipment which can feed the wooden core, the parent stock and the wooden core are subjected to extrusion together to form proximate matter; c. the proximate matter formed in the step b is cut into floor blocks; and d. the end faces of the floor blocks in the step c are sealed. The high-intensity wood-plastic composite floor can be manufactured, the floor cannot crack, warping and deforming are avoided, mildewing rotting is avoided, and pollution is avoided.

Description

technical field [0001] The invention relates to a floor and a manufacturing method thereof, in particular to a wood-plastic composite floor and a manufacturing method thereof. Background technique [0002] In the existing methods of manufacturing wood-plastic composite (WPC) floors based on extrusion, molding or bonding, the manufactured wood-plastic floors have low strength and are not suitable for use as long-span floors, and are too heavy due to their high density. , prone to creep and other deficiencies. And the manufacture of floors such as solid wood flooring, solid wood composite flooring, impregnated paper laminated wood flooring, bamboo flooring, cork flooring, bamboo-wood composite flooring in the prior art is all subject to the specification of the material, and needs to be in the floor base during the manufacturing process. A large amount of adhesive is used to bond the floor materials. The adhesive layer of these bonded floors is easily exposed to the air. On t...
