Embodiment

[0019] Embodiment: make 2400*1200*10mm, environmental protection decorative board.

[0020] 1. Parameters in the material preparation stage: (1) The moisture content of the fast-growing poplar rotary cut veneer is below 7%, the size is 615*1220*2.5mm, and the density is 0.31g / cm 3 . (2) Refer to the density of red pine: 0.40-0.50g / cm 3 , the density of the finished environmentally friendly decorative board is 0.45g / cm 3 . (3) Determining the compression ratio: the density of the finished environmentally friendly decorative board ÷ the density of the fast-growing poplar rotary-cut veneer = 0.45 ÷ 0.30 = 1.5, and the thickness of the billet is established to be 15mm. For the form of veneer assembly, see the attachment figure 2 , 3 , 4, 5, 6. (4) Determine the amount of sizing: by m 2 165-200g.

[0021] 2. Determine the process parameters during pressing. (1) The curing temperature of the modified urea-formaldehyde resin and melamine blend is 125°C, the time is 5-8min, ...

Abstract

The invention relates to a method and a manufacturing process (attached drawing) for producing an environmentally-friendly decorative board by using a fast-growing poplar rotary cut veneer, which mainly solve the problems of low bonding strength, high probability of cracking and warping, uncompacted corner, high formaldehyde release, low nail holding power, high probability of falling, poor water proofing, moisture proofing and fire proofing performance existing in the conventional decorative board. The production method and the manufacturing process are mainly characterized in that: the density of a finished board is determined by using the apparent density (actually measured) of the fast-growing poplar rotary cut veneer in comparison with the density of red pine; a compression ratio is determined according to the two densities; and the thickness of an assembly is determined by using the compression ratio. Modified urea-formaldehyde resin and melamine resin are mixed as an adhesive; and parameters for a hot pressing process of a board blank are determined according to the compression ratio, and curing temperature, time and pressure of an adhesive. Decorative paper which is soaked in the adhesive solution is adhered to the surface and the back surface of the board blank formed after hot pressing, and then secondary hot pressing is performed to finish the final environmentally-friendly decorative board. The production method and the manufacturing process have the advantages of mechanical property of the finished product beyond that of timber, no formaldehyde release, water proofing, moisture proofing, fire proofing and cracking prevention effects, high nail holding power, repeatedly detachable hardware and small variability.

Description

Technical field: [0001] The invention relates to a method and a manufacturing process for producing an environment-friendly decorative board by using fast-growing poplar rotary-cut veneer. Background technique: [0002] At present, we often use the following types of boards in the decoration process: plywood, particle board, density board, fiberboard, blockboard, and most of these boards are post-laminated veneer. Only the furniture in the kitchen and bathroom has veneers, and the core boards are also the above-mentioned boards. But all there are the following problems in the boards of these facings and the boards of post-adhesive facings: 1, the bonding strength of the core board itself is low, and it is easy to open the glue and warp. 2. The waterproof, fireproof and moisture-proof performance of the back-adhesive veneer is poor. 3. The post-adhesive veneer is artificially bonded at room temperature and is easy to crack, and the edges and corners are not firmly pressed a...
