Because decorative veneer veneers need to be painted after being used in furniture, toxicity and dust are produced in the process, which pollutes the environment, prolongs the home improvement process, and increases costs. The melamine impregnated paper veneer can omit the oil decoration process because of the impregnated paper layer on the surface, and its huge variety of patterns enriches the product series. At present, the application of melamine-impregnated paper veneer in furniture is in full swing, and there is a tendency to replace decorative veneer veneer. At present, the ecological paint-free decorative panels can be divided into plywood ecological paint-free decorative panels, blockboard ecological paint-free decorative panels, particleboard ecological paint-free decorative panels, and MDF ecological paint-free decorative panels according to their substrates. These four common ecological paint-free decorative panels generally use urea-formaldehyde glue, and their environmental protection level is generally low. At present, the market is generally E1 level or even E2 level, and rarely reaches E0 level. Furniture is used indoors, which is environmentally friendly. The level requirements are very high, and the general requirement is to reach the E0 level. The price of plywood ecological paint-free veneer is relatively high, and it is easy to deform.

One embodiment of the present invention is: the OSB slab 1 is formed by bonding two pieces, and the upper and lower surfaces of which are sanded with a fixed thickness are covered with natural veneers or recombined decorative veneers respectively to form an OSB substrate , and then at least one sanded surface of the OSB substrate is covered with a layer of impregnated paper finish layer 3 .

Another embodiment of the present invention is: the OSB slab 1 is formed by bonding two pieces, and the upper and lower surfaces of the OSB slab are sanded with a fixed thickness and are respectively covered with natural veneer or formaldehyde release The cardboard composite facing layer 3 is composed of recombined decorative veneer and impregnated paper limited to E0 grade.

The following embodiments take a single OSB slab 1 as an example, and two or more OSB slabs 1 are bonded together to form a composite OSB slab, and other embodiments can be obtained as long as the following embodiments are replaced.

Embodiment 1: the preparation method of a kind of above-mentioned OSB ecological paint-free finish furniture board described in the utility model, it comprises the steps:

a) The production of OSB slabs, the raw materials are processed into thin and long wood chips with a length of 40-120mm along the wood grain direction, a width of 5-20mm, and a thickness of 0.3-0.7mm, which are paved into 3 or 4 layers vertically and horizontally by gluing The staggered structure is made by continuous hot pressing process;

b) Composite by direct paste method, the above-mentioned OSB base plate and 0.1-3.0mm thick veneer are pasted with E0 glue to form an OSB substrate, and then the surface of the OSB substrate is covered with a layer of impregnated paper finish layer.

In the step b), the hot pressing process parameters of bonding the OSB substrate and impregnated paper are unit pressure 0.5-1.5 MPa, time 3-15min, temperature 110-180°C.

Embodiment 2: the preparation method of a kind of above-mentioned OSB ecological paint-free facing furniture board described in the utility model, it comprises the steps:

a) The production of OSB slabs, the raw materials are processed into thin and long wood chips with a length of 40-120mm along the wood grain direction, a width of 5-20mm, and a thickness of 0.3-0.7mm, which are paved into 3 or 4 layers vertically and horizontally by gluing The staggered structure is made by continuous hot pressing process;

b) Compounding by pasting method, now compound the veneer with a thickness of 0.1-3.0mm and impregnated paper to form a cardboard composite facing layer, and then glue the cardboard composite facing layer to the OSB blank with EO glue.

In the step b), the hot pressing process parameters when the veneer is combined with the impregnated paper are unit pressure 0.5-1.5 MPa, time 50-100s, temperature 110-180°C, and the paperboard composite facing layer and OSB baseboard are made of The hot pressing process is the unit pressure of 0.5-1.5 MPa, time of 4-15min, and temperature of 90-150°C.

In the above-mentioned step a) of the present invention, the continuous hot pressing process includes: hot pressing is divided into three areas: boosting area, pressure holding area, thickness setting area, and pressure relief area. The three elements of hot pressing, that is, the unit pressure and time are different, and the density is controlled within the range of 0.45-0.6g/cm3.

The utility model adjusts the structure of conventional OSB, changes the hot-pressing process parameters during continuous hot-pressing, and reduces its density, which not only satisfies the function of the furniture board, but also reduces the cost of the OSB blank board. The OSB slab is sanded to a certain thickness, and then laminated and veneered to ensure its flatness. At the same time, it is given a paint-free finish function. Consumers can choose impregnated paper with different patterns according to their preferences. The processing technology of the laminated veneer after sanding with a certain thickness generally adopts the direct paste method and the laminated method, and this is similar to the ordinary ecological paint-free veneer furniture board. The surface finish of the direct-attach method is better, and the cost is lower. The production efficiency of the paste method is higher, but the finish is slightly worse. In order to reduce production costs and ensure the brightness of the final board surface, the direct paste method is generally used.

For the balance layer between the OSB slab and the impregnated paper, the utility model first considers the use of 0.1-3.0mm natural veneer or recombined decorative veneer with a formaldehyde release limit of E0 level, which not only ensures the final flatness and environmental protection of the product performance, taking into account the cost of the product.

The so-called direct sticking process is to first sand the OSB base plate to a certain thickness, and then paste a 0.1-3.0mm veneer on both sides, and then make the OSB base material after hot pressing and sanding, and then paste the surface after the base material is cooled. . The so-called re-adhesive process is to first combine 0.1-3.0mm veneer with impregnated paper to form a cardboard, and then combine it with the OSB blank board after sanding and sanding to form a finished OSB ecological paint-free decorative panel.

The OSB ecological paint-free veneer furniture board is generally double-sided veneer, and the direct lamination process generally requires two film application, while the re-lamination process generally only needs one combination, and double-sided cloth glue is enough.

The OSB ecological paint-free decorative furniture board is made of an OSB substrate by pasting a veneer on an OSB base plate, and then pressing and pasting melamine-impregnated paper on the substrate to make a paint-free decorative panel, which is easy to process. Its cost is equivalent to that of blockboard core, particle board core, and MDF core ecological paint-free decorative panel, and is greatly reduced compared with plywood core ecological paint-free decorative panel. The finished product not only has all the superior mechanical properties and environmental protection properties of OSB, but also does not need to be painted during decoration and use, which reduces environmental pollution. This product will be widely used in the field of interior decoration.
