Problems solved by technology

The disadvantage of this method is that the pressure is high, and the direct veneer will increase the compression rate of the substrate plywood or blockboard, and because the thickness and flatness of plywood, especially blockboard, is lower than that of medium density fiberboard and the uniformity of a single sheet, It is easy to cause problems such as dried flowers (that is, local browning), uneven thickness and flatness, and high waste and defective rates, which affect product quality and user use

Embodiment 1

[0020] Embodiment 1: refer to figure 1 . A high-flatness paint-free simulation ecological board, including a substrate layer 1, at least one layer of technical wood veneer 2 is provided on the upper and lower sides of the substrate layer 1, and melamine impregnated paper 3 is pasted on the outside of the technical wood veneer 2. An adhesive is provided between the sheet 2 and the substrate layer 1 . The substrate layer 1 is a composite board composed of a middle board 5 and a core board 4 of multi-layer plywood or blockboard.

Embodiment 2

[0021] Embodiment 2: refer to figure 2 . The substrate layer 1 is a composite structure of multi-layer plywood 6 .

Embodiment 3

[0022] Embodiment 3: refer to figure 1 . A method for manufacturing a high-flatness paint-free simulation ecological board is characterized in that it comprises the following steps:

[0023] 1) Put the melamine-impregnated paper (3) and technical wood veneer (2) into the hot press for hot pressing and veneering. The hot pressing temperature is 110°C-130°C, the unit pressure is 1-1.6MPa, and the time is 3-6 Minutes, the composite board is cooled and stored after hot pressing;

[0024] 2) Apply adhesive on one side or both sides of the substrate layer (1) that has been sanded to a certain thickness, and pre-press the composite board prepared in the previous step and the substrate layer (1) that has been coated with glue. The unit pressure at room temperature is 0.3-0.7MPa, and the time is 20-60 minutes;

[0025] 3) After pre-pressing, the slab is sent to a hot press machine for hot-pressing and bonding. The hot-pressing temperature is 70-90°C, the unit pressure is 0.3-0.7MPa,...

Abstract

The invention relates to a high-flatness paint-free simulation ecological plate and a manufacturing method thereof. The ecological plate comprises a base plate layer (1), at least one of upper and lower sides of the base plate layer is provided with a layer of technical wood sheet (2), melamine impregnated paper (3) is pasted outside the technical wood sheet (2), and the technical wood sheet (2) and the base plate layer (1) are bonded by an adhesive. According to the high-flatness paint-free simulation ecological plate and the manufacturing method thereof, the problem of drying (partial brown) caused by uneven partial thicknesses of base plates and uneven moisture content in production of paint-free ecological plate products is solved, and the product percent of pass is improved to above 99.9% from around 90%.

Description

technical field [0001] The invention relates to a wooden board in the field of building decoration and furniture manufacturing, in particular to a high-flatness paint-free simulation ecological board and a manufacturing method thereof. Background technique [0002] At present, the paint-free ecological board is pasted on the upper and lower surfaces of wooden plywood or blockboard with melamine-impregnated paper. The production process is generally a direct hot pressing method. Chinese patent publication CN102642220.A discloses a paint-free ecological blockboard with poplar base material and its production process, which illustrates the production method. The hot pressing parameters are pressure 16-18MPa, temperature 115-120°C, and time 6-8 minutes. The disadvantage of this method is that the pressure is high, and the direct veneer will increase the compression rate of the substrate plywood or blockboard, and because the thickness and flatness of plywood, especially blockbo...
