Description
Technical field:
The present invention relates to plywood production technical field, the production technology of a kind of plywood.
Background technology:
Plywood is to be peeled into veneer by juggle or become veneer by flitch slicing, then stick with glue three layers of agent gluing or
The board-like material of multilamellar, generally uses odd-level veneer, and make the orthogonal gluing of machine direction of adjacent layer veneer form.Existing
The adhesive of plywood production is typically the most with heat cured adhesive, and some adhesive thermosetting is poor, thermoset processes
Time is longer, makes viscosity not enough, and when temperature is higher, viscosity is substantially reduced especially, is unfavorable for the molding of plywood, and plywood becomes
Intensity after type is not enough, and additionally in prior art, wood chip is not the most the most smooth, all becomes curly, particularly to some wood
The wood chip of the trees that matter itself is harder, all the more so, the wood chip of curling is not easy to tiling arrangement, is also not easy to being pressed into of later stage
Type, and in prior art, gluing is all a gluing, the most uneven, and before compaction, sizing material is the driest, is unfavorable for
Compressing, the hardness of wood chip is high, later stage precompressed, hot pressing time long, speed is slow, and internal stress is the biggest, is easily deformed
With come unglued.
Summary of the invention:
The technical problem to be solved is to provide a kind of required precompressed hot pressing time short, and speed of production is fast, interior
Stress is little, it is not easy to the production technology of plywood come unglued and deform.
Solve the technical problem that used following technical scheme:
A kind of production technology of plywood, it is characterised in that: comprise the following steps
1) log is removed the peel, and ring cutting becomes wood chip, then dries；
2) gluing, by adhesive on wood chip, described adhesive is made up of following components by weight, Lauxite 80～
100 parts, celluloid 20～40 parts, polyphenylene sulfide 10～20 parts, firming agent 6～10 parts, filler 30～50 parts, modifying agent 5
～9 parts and water 80～100 parts；
3) wood chip is prevented on conveyer belt, by heater, wood chip is carried out thermoplastic, heating-up temperature be 60～
80 DEG C, then by pressure roller, wood chip is flattened；
4) glue, by adhesive along the uniform glue in both sides of wood chip；
5) assembly, tiles uniform for wood chip layered, notices that thickness is uniform；
6) precompressed, is filled into the base organized in hot press and carries out precompressed, and the temperature of precompressed is；60～80 DEG C, pressure 8～
10MPa, the time controls between 60～80 minutes；
7) finishing hot pressing, by avris trimmed, then carry out hot pressing.110～120 DEG C, pressure 11～15MPa, time
Between control between 20～30 minutes；
8) fill up putty, putty filled up at the hole on sheet material after hot-pressing, crackle and gap, flat carry out floating；
For coming unglued, at bubbling, outside is peeled off, inserts putty the most floating；
9) saw edge forming, obtains plywood.
Described firming agent includes by weight, phoxim 6～10 parts, oxalic acid 2～3 parts, methyl salicylate 2～3 parts and
Hexamethylenetetramine 1～2 parts.
Described filler includes by weight, wood powder 5～8 parts, conch meal 2～4 parts and heavy calcium carbonate 2～4 parts.
Described modifying agent includes by weight, tannic extract 5～10 parts, gelatin 3～8 parts and Quercetin 1～2 parts.
The production technology of the present invention has softening, flattens and the step of early stage glue, be possible not only to increase wood chip gluing
The uniformity of glutinous agent, the particularly avris position of wood chip, and the wood chip after softening and flattening, it is simple to arrangement, internal stress is little, can
To be greatly shortened the time of later stage precompressed and hot pressing, pressure, thus accelerate the speed produced, improve efficiency, additionally can be significantly
Reduce the internal stress within plywood of production department, thus reduce the probability of delamination of plywood and deformation.
The adhesive that in the present invention, raw material components is produced has the highest gumminess, and time hot-forming, gumminess reduces very
Little, the firming agent in the present invention is so that adhesive has more preferable thermosetting effect, and the speed of thermosetting is fast；And the filling out of the present invention
The intensity of material is high, during preparation and the later stage hot-forming during will not produce more degeneration, can be with intensity
Lasting efficacy, and the present invention also added modifying agent, its viscosity can be increased further, adhesive can be protected not simultaneously
It is oxidized easily.
The invention has the beneficial effects as follows: precompressed hot pressing time of the present invention is short, speed of production is fast, and internal stress is little, it is not easy to open
Glue and deformation, it is good that adhesive has thermosetting, and viscosity is high, and intensity is high, and endurance is good, it is not easy to rotten advantage.
