Technical background
Core-board is to make furniture and decorations one of main material of wood-based plate.Since core-board have uniform specification, processability by force, characteristics such as not yielding, other material of Pasting, therefore enjoy liking of upholstery and decorations user, be widely used at present.But the mass discrepancy of core-board is very big, if select for use improper, the easiest construction quality and the environmental issue of occurring.The core-board of production technology difference influences working strength and engineering decorative quality, and the core-board of not environmental protection can directly cause indoor pollution, threatens human health.Country has formulated core-board standard (GB/T5849-2006) with reference to international standard for this reason, and the PARA FORMALDEHYDE PRILLS(91,95) burst size divides 3 grades to limit.Wherein highest level is E 0Level, burst size of methanal is controlled at≤0.5mg/L, can be a kind of core-board of environment-friendly type directly in indoor use.Produce E 0The level core-board must use environmental-protection type adhesive, compares with traditional urea-formaldehyde resin adhesive, and its bonding strength is relatively poor relatively, the production cost height, thereby limited it and used widely.Therefore, group of domestic enterprise, the scientific research personnel of institution of higher learning have all carried out a large amount of research aspect the core-board production technology.Its objective is and improve core-board bonding strength and timber utilization rate, reduce production costs.Zhejiang Forestry Institute application " a kind of preparation method of core board for fine woodworker's board " (number of patent application: 01113049.0), it mainly is to be raw material with small dimension wood, thinnings, brush wood, through pre-place, comb separate, drying, applying glue, the assembly of mating formation, hot pressing, modifier treatment and post-production, make core board for fine woodworker's board, improved production efficiency, reduced energy consumption, the timber utilization rate height, production cost is low; Another patent " a kind of improved novel core board for fine woodworker's board and preparation method " (number of patent application: 02138600.5) of this institute's application, be to be raw material with small dimension wood or thinnings, brush wood, prepare, roll that comb is separated, vertically separation, transversely truncation, drying, applying glue, mat formation, make the used central layer of novel core-board after the technology such as hot pressing through raw material, also reached the same purpose of above-mentioned patent; " a kind of core-board processing technology " (number of patent application: 200410065907.2) of Changlin Wood Ind Co., Ltd. Huangshan City's application, its production technology comprises raw material saw system flitch, dry, fixed thick two-sided processing, multiple blade saw system bar, matching board, gluing, jigsaw machine jigsaw, force cooling, a sanding, paste horizontal veneer, precompressed, hot pressing, force cooling, the secondary sanding, paste dash board, the secondary precompressed, secondary hot pressing, three sandings of cutting edge, the finished product go-on-go, warehouse-in, i.e. " two press three sand " technology, and by using the cooling of formaldehyde catching agent and forced ventilation to reduce content of formaldehyde; " core-board with new structure and production technology thereof " (number of patent application: 01133469.X) of Teng Enrong application, mainly solve existing product because central layer partly splices, influence working strength and the engineering decorative quality and the outmoded backwardness of production technology of product, volume recovery is low, waste is big, complex process, problems such as cost height; " core-board and preparation method " (number of patent application 03106576.7) of Hua Xuanling research and development, it includes one deck block board at least, behind the block board that completes, after the single face gluing of block board, stick one deck Sawtooth Oak Bark, stick one deck musculus cutaneus again after the gluing, the compacting shaping forms after the high temperature thermosetting; " a kind of preparation method who is used for core board for fine woodworker's board " (number of patent application: 200610056934.2) of Beijing Forestry University, this method comprises preparation equal thickness lath, lath is carried out assembly and makes lath arrange the step of driving fit, also be included in before the assembly of lath, at central layer not under the situation of jigsaw, formaldehyde eliminating agent directly sprayed or brushes side at half bar, and under the situation of central layer layout, spray or brush the adhesive that is added with formaldehyde eliminating agent in the side of lath, make formaldehyde eliminating agent be coated in the back of lath, not only can produce formaldehyde limit control amount with this central layer and reach E with adhesive 1The environment friendly lumbercore plywood of grade standard, and prevented that adding the bonding strength that formaldehyde eliminating agent caused at core-board in glue reduces.
Goal of the invention the purpose of this invention is to provide a kind of new core-board processing technology, not only makes the formaldehyde limit control amount E that is up to state standards 0The standard of level core-board.Solved simultaneously in the core-board production and used environmental-protection type adhesive, bonding strength is poor, the difficult problem of unstable product quality.Improved timber utilization rate, reduced production cost, and reduced production cost because of using environmental-protection type adhesive to increase.
Summary of the invention
The technical scheme that this invention adopts is: the flitch good to drying, without thicknesser, fixed thick technology, directly cut bar with the high accuracy multi-disc; Jigsaw adopts the side compression machine splicing, and promptly first side pressure is the technology of jigsaw again, and it is inhomogeneous to have solved the lath width, the problem of jigsaw gummed intensity difference; Gluing uses no aldehyde environmental protection glue, and technology measure such as displays through employing low temperature, low pressure, prolongation hot pressing time, cushioning bar, and burst size of methanal is under control; Adopt secondary precompressed, secondary hot pressing, secondary sanding moulding process, guarantee that fully product surface is more smooth, smooth.A complete set of production technology comprises that raw material saw system flitch and dry, multi-disc cut bar, pendulum saw arrangement, row's plate, side pressure jigsaw, gluing, paste veneer, a precompressed, a hot pressing, cooling, a sanding, second glue spreading, subsides coverlay plate, secondary precompressed, secondary hot pressing, natural cooling, cutting edge and secondary sanding, finished product go-on-go, warehouse-in naturally.The veneer selection is in local fast growing high-quality poplar, and coverlay adopts the superfine veneer of import.
The core-board that the good effect of invention adopts above-mentioned processing technology to produce can improve timber utilization rate 8.3%, has reduced production cost relatively.Performance indications such as bonding strength have reached the national standard requirement, and wherein formaldehyde limit control amount is better than the regulation of national standard≤0.5mg/L through national wood-based plate quality supervision and test center check≤0.3mg/L, and the product appearance quality also is improved simultaneously.
