Description
Technical field:
The present invention relates to plywood production technical field, the production technology of a kind of waterproof pluwood.
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 plywood sticks the weak effect that agent is waterproof, and the plywood produced easily ftractures after rainwater, causes using
Life-span is low.Additionally in prior art, wood chip is not the most the most smooth, all becomes curly, particularly to some wooden itself relatively
The wood chip of hard trees, all the more so, the wood chip of curling is not easy to tiling arrangement, is also not easy to the compressing of later stage, and
In prior art, gluing is all a gluing, the most uneven, and before compaction, sizing material is the driest, is unfavorable for being pressed into
Type, 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 and comes unglued.
Summary of the invention:
The technical problem to be solved is to provide a kind of good water-proof effect, and required precompressed hot pressing time is short, raw
Product speed is fast, and internal 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:
The production technology of a kind of waterproof pluwood, comprises 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, UF resin 100～
120 parts, coking coal oil 10～20 parts, metallic soap 10～20 parts, alkanolamide 10～20 parts, firming agent 6～10 parts, filler 30～50
Part, modifying agent 5～9 parts and water 90～110 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, tartaric acid 5～7 parts, dimethyl carbonate 2～3 parts
With 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 waterproof effect, glue time hot-forming
Stickiness reduces the least, and 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 intensity of the filler of the present invention is high, during preparation and the later stage hot-forming during will not produce more change
Property, with the lasting efficacy of intensity, and the present invention can also added modifying agent, its viscosity can be increased further, the most permissible
Protection adhesive is not easy oxidized.
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, adhesive thermosetting is good, and viscosity is high, and intensity is high, and endurance is good, it is not easy to rotten, good water-proof effect.
