Wood is becoming more scarce as a natural resource, and a series of laws and regulations are formulated in many countries to strengthen the protection of forest resources, which brings good opportunities and strong market challenges to the development of the floor industry.
The surface decoration of the floor can obtain the appearance effect of beautifying the floor, improve the use value of the floor and expand the selection range of the manufacturing materials of the floor. At present, in order to enable the surface of a wood composite floor taking middle-low grade wood (such as fast-growing woods) as a surface board to have the decorative effect of valuable wood, the aim is achieved by a roller direct printing or ink spraying mode in most of the industry. However, the coloring effect of the roller direct printing is not rich, the roller printing texture is not clear, the texture layering sense is poor, and the requirement on equipment design is high; the thickness of the pattern layer sprayed by the ink puts high requirements on the subsequent processing and coating of the paint protective layer, and the pattern sprayed by the ink has low resolution and unclear pattern boundary, thereby affecting the decorative effect.
Disclosure of Invention
In view of the above-mentioned shortcomings in the prior art, the present invention provides a transfer-printed wood floor, which can achieve the effect of beautifying the appearance of the floor, increase the value of the floor, and expand the selection range of the floor manufacturing materials by transferring various decorative patterns on the surface of the wood floor.

In the preferred embodiment of the invention, the wood substrate is a single solid wood board.
Furthermore, the wood substrate is formed by attaching a decorative surface plate on a substrate plate; wherein the substrate board includes but is not limited to particle board, multi-ply plywood, fiber board, stone plastic board, PVC, etc.; the decorative surface plate is not particularly limited in material type, and the thickness is 0.2-4 mm.
In a preferred embodiment of the present invention, the transparent primer layer is composed of one or more primer layers, and has a thickness of 0.03 to 0.5mm, preferably 0.05 to 0.2 mm. The base coat is a cross-linked polymer of a mixture which can be cured by ultraviolet light and takes acrylate functional resin as a main component, wherein the acrylate functional resin is a transparent resin taking a prepolymer and/or oligomer and/or monomer of free radical polymerization double bonds capable of being cross-linked and polymerized by ultraviolet light irradiation as a main component, and the content of the acrylate functional resin before polymerization is not less than 80%. The prepolymer, oligomer and monomer may be used alone or in combination of two or more in any ratio.
Further, the mixture taking the acrylate functional resin as the main component is coated on one side of the wood substrate and is partially cured by ultraviolet radiation to form the transparent bottom coating.
Further, the mixture taking the acrylate functional resin as the main component is coated on one side of the wood substrate and is cured or partially cured by ultraviolet radiation to form a first base coat, then the mixture is continuously coated and cured or partially cured to form a second base coat, and the like, and when a plurality of base coats are formed, the surface of the mixture is completely cured to form a transparent protective layer. And the uppermost coating of the transparent base coating, namely the coating closest to the transfer printing layer, is cured by ultraviolet radiation, and finally the transparent base coating is formed by the plurality of base coatings.
The partial curing means that the mixture coating layer with the acrylate functional resin as the main component is cured into a non-liquid coating layer, and sticky feeling is achieved by contacting the back of the hand.
Further, the transparent primer layer may be colored, and a coloring agent may be added to the mixture mainly containing the acrylate functional resin before the transparent primer layer is cross-linked and polymerized, wherein the coloring agent is present in an amount of about 0 to 10% by mass based on the transparent primer layer.
Further, the transparent primer layer further contains additives such as abrasion resistant particles and a flame retardant, and is added to the mixture containing the acrylate functional resin as a main component before the transparent primer layer is crosslinked. The wear-resistant particles comprise alumina materials, silicon carbide, diamond, silicon oxide and the like in a limited range, and the mass percentage of the wear-resistant particles accounts for 0-10% of that of the transparent bottom coating. The wear resistant particles are dispersed in the mixture having the acrylate functional resin as a main component with an average particle size of 5 to 50 μm in a narrow distribution, and the narrow distribution of particles may have a standard deviation of less than 30% of the average particle size.
Further, in the transparent base coat layer, the additives, colorants may be present only in selected layers of the multi-layer base coat layer, the selected layers being one or more layers. For example, the first and third basecoats contain wear resistant particles and the second basecoat contains a colorant.
In a preferred embodiment of the present invention, the transfer layer is a layer obtained by peeling off a transfer film and transferring the transfer film to the surface of a wooden substrate having a transparent primer layer on the surface, and has a thickness of 0.01 to 0.05mm, preferably 0.02 to 0.03 mm. The transfer layer is arranged on the transparent base coat layer side and is formed by laminating a transparent layer, a pattern layer and an intermediate layer in sequence, and the pattern layer is arranged below the transparent layer.
Further, the transparent layer is disposed on the transparent undercoat layer by transfer printing. The resin used for the transparent layer includes, but is not limited to, polyolefin resins such as vinyl chloride-vinyl acetate polymers, polypropylene, and polyvinyl chloride resins, and is easily mixed with a heat-transfer colorant such as a sublimation dye.
Further, the pattern layer is a high-quality pattern layer disposed below the transparent layer. The pattern thereof is not particularly limited and may be a wood grain, a water wave, a charpy pattern, a portrait of a person, or the like. The pattern layer has good durability, and contains dye and adhesive resin which are well known in the technical field of sublimation type thermal transfer printing sheets. The dyes include, but are not limited to, methine dyes, azopyrrole dyes, azine dyes, acridine dyes, phenylazo dyes, triazolazo dyes, spiropyran dyes, indoline spiropyran dyes, rhodamine lactam dyes, and the like. The binder resin includes, but is not limited to, methacrylic resins, polyurethane resins, polyester resins, and the like.
Furthermore, the thickness ratio of the pattern layer to the transparent layer is 0.5-1: 1.
Further, the intermediate layer is a layer formed of an adhesive material, and includes, but is not limited to, (meth) acrylic resins such as acrylic/methacrylic resins, polyester resins, polyamide resins, acrylate resins, ethylene- (meth) acrylate copolymers, ethylene- (meth) acrylic copolymers, polyurethane resins, cellulose resins, and the like. The intermediate layer may contain only one material, or may contain two or more materials.
Furthermore, the thickness of the middle layer is 1-10 μm, and preferably 1-4 μm.
In the preferred embodiment of the invention, the transparent protective layer is composed of a plurality of coatings, and the thickness of the transparent protective layer is 0.03-0.5 mm, preferably 0.05-0.2 mm. Wherein, the coating is a cross-linked polymer of a mixture which can be photo-cured by ultraviolet light and takes acrylate functional resin as a main component. The acrylate functional resin is a transparent resin which takes prepolymer and/or oligomer and/or monomer of free radical polymerization double bond capable of generating cross-linking polymerization by ultraviolet irradiation as main components. The prepolymer, oligomer and monomer may be used alone or in combination of two or more. The content of the acrylate functional resin before polymerization is not less than 80%.
The transparent protective layer provides high hardness, scratch resistance, abrasion resistance, water resistance and stain resistance to the floor. The transparent protective layer coating may be formed by: the transparent protective layer coating is applied to the transfer layer by a known coating method such as roll coating, blade coating, gravure coating, etc., and then cured by irradiation with ultraviolet light. The transparent protective layer is formed by coating and curing the laminate several times.
Further, coating a mixture taking the acrylate functional resin as a main component on the transfer printing layer, and curing or partially curing the mixture through ultraviolet light radiation to form a first coating; a second layer of the acrylate functional resin based mixture is then applied over the first layer of coating and subsequently cured or partially cured by uv radiation to form a second layer of the coating. One or more of said acrylate functional resin based mixtures are applied to a second of said coating layers.
