Abstract
The process of making high strength anticorrosive integrated plate material includes the following steps: forming narrow timber strip with wood leftover and low grade timber and through cutting, pressure dipping timber strip in modifying phenolic resin in solid content of 10-15 % and added preservative and serving as modifier and adhesive, stoving in a circular tunnel kiln at 90 deg.c for 30-40 min to reach water content of 12-15 %, arranging in a mold to form blank, cold pressurizing at 600-800 kg/sq m pressure, curing at 140-160 deg.c, ageing and cutting and finishing. The process is simple, and the produced plate material has density of 1-1.2, high strength, high anticorrosive performance, low cost and wide application.
Description
Technical field
The present invention relates to a kind of structure artificial board manufacture method, particularly a kind of manufacture method of high-strength anti-corrosion integrated material.
Background technology
At present, make the field at wood-based plate, China's glued board, fiberboard, particieboard, core-board four big plate kind development are rapidly.Introduce 2003 annual national total outputs according to data and reach 4553.36 cubic metres and leap to the second in the world, but structure wood-based plate slower development, product shortage, domestic required dependence on import.Because the structure wood-based plate uses as primary structure member usually, and its mechanical property, water resistance, antiseptic property, dimensional stability are all had higher requirements.Existing processing method can not satisfy the needs of manufacturing structure wood-based plate.
The China's Forest Resources poorness, the wood supply anxiety.The high-quality timber that large diameter tree material and density are big, intensity is high is more rare.But the artificial forest cultivated area of fast growing wood such as poplar, China fir is wide, the output height is the primary raw material of wood-based panel industry, but this class density of wood is little, intensity is low, material is loose, the bulking performance is big, can not be directly uses as the raw material on building element and hardwood furniture, floor.China's glued board year output is 2100 ten thousand steres, produces a large amount of veneer edge strips in the production and goes out of use, and only reaches with the 5% veneer edge strip that calculates annual generation and causes very big waste more than 100 ten thousand steres.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, provide a kind of technological process simple and practical, utilize discarded veneer edge strip and low-grade fast growing wood manufacture method for the high-strength anti-corrosion integrated material of raw material.
The embodiment of the present invention's employing is as follows for achieving the above object:
A kind of manufacture method of high-strength anti-corrosion integrated material, implementation step is as follows:
(1) selection prepares veneer strip
When adopting the discarded veneer edge strip in plywood factory, reclaim the back and put in order to shear by the manual sort and be processed into specification and be: the veneer fillet of length 200-1300mm, width≤5mm, thickness 0.5-3mm through wooden skin filament cutter.
When adopting poplar, China fir log, make veneer with conventional rotary cutting method, the wooden skin filament cutter shearing of process is processed into specification and is: the veneer fillet of length 1300mm, width 3-5mm, thickness 1-2mm.
Above-mentioned veneer fillet drying is handled, and moisture content is controlled in the 8%-12% scope;
(2) carrying out material remodeling handles
Use 2122# liquid water-soluble phenol-formaldehyde resin modified to use as adhesive as the modifier and the while of material.The solidfied material content of phenolic resins glue is 10%-15%, and the permethrin anticorrisive agent of interpolation glue weight 3%-5%, the veneer fillet of getting ready is immersed in the glue of closed container fully, with the method that supercharging heats material is carried out the modification processing, promptly in container, heat in the airtight back of container.Pressure is 0.3-0.4MPa, and temperature is 40 ℃ ± 5 ℃, and dip time is 3-5 hour, makes the interior and abundant absorption in the cell membrane surface glue of lumen of material fiber, and state reaches capacity;
(3) the dry processing
Adopt the small width veneer bar after circulating tunnel drying kiln is handled modification to carry out drying continuously, temperature is 90 ℃ ± 10 ℃, and wind speed is 2-3m/s, and the guipure gait of march is 1.5-2m/min, be 30-40 minute drying time, and dried moisture content is controlled in the 12%-15% scope.
(4) assembly
By behind the quantitative weighing that the veneer fillet is forward parallel layered stacked in mould by the fibre length direction, billet can be overlapping to overlap and form blank;
(5) cold pressing
Carry out cold pressing treatment, pressure is 600-800kg/cm
2, effectively compacting material increases its density, and the cover plate of mould is pinned in the compression back with bolted;
(6) heat cure is handled
Send into together with mould and to carry out heating cure in the high temperature kiln, solidification temperature is 140 ℃-160 ℃, and air inlet mean wind speed 1.8-2.5m/s, air outlet mean wind speed are 0.8-0.85m/s, and be 4-6 hour hardening time.After reaching hardening time, wind cooling temperature lowering is to≤60 ℃ of kiln discharges.Naturally cool to≤demoulding 40 ℃ the time together with mould behind the kiln discharge, make the complete gluing and solidifying of blank be whole integrated timber;
(7) ageing is handled
Integrated timber is piled up neatly, under nature, put 24-48 hour, make integrated timber and environment temperature, humidity consistent;
(8) sawing shaping
Six faces to integrated timber carry out sawing, slicing is handled, and make six faces smooth.By product specification, carry out the scale cutting;
The specification limit of described high-strength anti-corrosion integrated material: length 2000-20000mm, width 105-120mm, thickness 160-200mm.
The invention has the beneficial effects as follows: adopting discarded veneer edge strip and low-grade fast growing wood is raw material, can effectively save timber resources and form the recycling of discarded object, reduce the cost of raw material, mainly adopt the heat cure two-step method manufacturing of colding pressing, particularly the phenol-formaldehyde resin modified that has an anticorrisive agent by employing carries out abundant impregnation to material and tamps the material fiber lumen and impose strong pressure and cold pressing, can effectively improve wood performance, it is wooden soft to change it, defectives such as density is little, make its density increase water resistance, antiseptic property is improved, and reduces the heat-energy losses in traditional hot-press method simultaneously, energy-saving and emission-reduction are beneficial to environmental protection.
The integrated timber density that the present invention makes through the heat cure of colding pressing can reach 1-1.2, quite traditional hot compacting make≤0.8 panel density had and significantly improved, and can be widely used in beam, post, joist, door window frame, open-air floor, Furniture panel, stair tread, handrail and the required material of car and boat plate of building; High density reaches high strength, and indeformable, good toughness, antiseptic property are good.Cost price descends more than 30%, finished product price decline 40%-50%.Preparation technology of the present invention is simple, and manufacturing environment, conditional request are loose, with short production cycle, and effect is remarkable, selection, is widely used.
