Embodiment 1

[0024] First of all, the wear-resistant impregnated paper containing aluminum oxide purchased from the general building materials market is laid on the surface of natural veneer, and then hot-pressed at 168°C to make the two firmly bonded to obtain a composite surface.

[0025] Secondly, fully stir the polyethylene and wood fibers and heat them to 160°C, and extrude them according to a predetermined thickness to obtain a wood-plastic mixed layer. Wherein, the particle size of wood fiber is 80 mesh. In the mixed layer, the percentage by weight of polyethylene is 30%.

[0026] Again, keep the temperature of the obtained wood-plastic mixed layer at 100°C, and lay an ethylene vinyl acetate copolymer resin layer with a temperature of 110°C on the surface of the mixed layer by extrusion to obtain an intermediate slab.

[0027] Finally, keep the temperature of the aforementioned intermediate slab at 100°C, lay the previously obtained composite surface layer on the surface of the eth...

[0029] First of all, the wear-resistant impregnated paper containing aluminum oxide purchased from the general building materials market is laid on the surface of natural veneer, and then hot-pressed at 180°C to make the two firmly bonded to obtain a composite surface.

[0030] Secondly, fully stir the polypropylene and crop straw fibers and heat them to 180°C, and extrude according to a predetermined thickness to obtain a wood-plastic mixed layer. Wherein, the grain size of the crop straw fiber is 160 mesh. In the mixed layer, the weight percentage of polypropylene is 50%.

[0031] Again, keep the temperature of the obtained wood-plastic mixed layer at 110°C, and lay an ethylene ethyl acrylate copolymer resin layer with a temperature of 115°C on the surface of the mixed layer by extrusion to obtain an intermediate slab.

[0032] Finally, keep the temperature of the aforementioned intermediate slab at 140°C, lay the previously obtained composite surface layer on the surface o...

Embodiment 3

[0034] First of all, the wear-resistant impregnated paper containing aluminum oxide purchased from the general building materials market is laid on the surface of natural veneer, and then hot-pressed at 208°C to make the two firmly bonded to obtain a composite surface.

[0035] Secondly, the mixture of polyvinyl chloride, wood fiber and crop straw fiber is fully stirred and heated to 220°C, and extruded according to a predetermined thickness to obtain a wood-plastic mixed layer. Among them, the particle size of wood fiber and crop straw fiber is 220 mesh. In the mixed layer, the percentage by weight of polyvinyl chloride is 70%.

[0036] Again, keep the temperature of the obtained wood-plastic mixed layer at 120° C., and lay a polyamide resin layer with a temperature of 120° C. on the surface of the mixed layer by extrusion to obtain an intermediate slab.

[0037] Finally, keep the temperature of the aforementioned middle slab at 180°C, lay the previously obtained composite s...

Abstract

The invention relates to a composite floor and a preparation method thereof. Thermoplastic plastics and wood powder are mixed and extruded to obtain a mixed layer, and then the mixed layer is mixed with thermofusible resin and extruded to obtain a profile which is taken as basic material of the floor, a decorating layer and an exterior wear-resisting layer are laid on the surface of the basic material of floor in sequence to obtain a floor blank, finally, after processes like conventional gouging and the like, an end product of composite floor is obtained. The obtained composite floor has the natural grain and the amenity of the solid wood floor, and overcomes the shortcomings of non-watertight, being easy to rot, easy to be deformed and low wear resistance of the conventional wood floor. The preparation method of the composite floor is simple and feasible and has low cost.

Description

technical field [0001] The invention relates to a composite floor for decorating indoor floors of buildings and a preparation method thereof, in particular to a composite floor whose cross-section presents a layered plate structure and a preparation method thereof. Background technique [0002] Among the existing floor covering materials, the use of wood flooring has been widely accepted by people. However, in actual use, wooden floors will be deformed, decayed, or exposed to insects when exposed to water and damp. These problems have not been well resolved. At the same time, solid wood flooring will consume a large amount of natural resources, deteriorate the ecological environment, and damage the common living environment of human beings. Although solid wood composite flooring and laminate flooring can reduce the number of natural forests, they consume high energy consumption in the production process and will Produce "three wastes" discharge problems such as waste, wast...
