Description
Technical field
The present invention relates to a kind of production technology of artificial wood skin, more particularly to a kind of no Form aldehyde release can be used as surface
The production technology of the artificial wood skin of ornament materials.
Background technology
Recombinant Wood, also known as sham wood, laminated veneer lumber, is with common wood（Such as poplar）Rotary cut venner is raw material, by dye
Color, the machine direction gluing composition base by tree, gluing and then it is pressed into flitch by press, then from certain to being formed with ply
The direction of angle, sheet material or slicing into veneer are made of saw.The attribute of its existing timber, has science and technology to bring new intension again.Section
Skill wood can both emulate those increasingly rare and expensive natural rare trees, and various more artistic feelings can be createed again
Beautiful decorative pattern and pattern.
Recombinant Wood is compared with natural wood, abundant, numerous in variety with color and luster；Finished product utilization rate is high；Production development potentiality are big；
Decoration book size is roomy；Be unlikely to deform, it is easy to process and can carry out anti-corrosion, it is mothproof, fire prevention（It is fire-retardant）, it is moisture resistance treatment etc. spy
Point, is widely used in Furniture manufacture and interior decoration and replaces the solid wood board and slicing veneer of natural rare tree.
But due at present production the commonly used urea-formaldehyde resin adhesive of Recombinant Wood, and Recombinant Wood production generally require it is cold
It is cured, and the adhesive of low content of free formaldehyde is extremely difficult to ideal effect, the Form aldehyde release problem of Recombinant Wood is as in production
A great problem.Further, since the Recombinant Wood cold curing time of urea-formaldehyde glue production is more long, Recombinant Wood production efficiency is directly results in
Low, the production cycle is long, the low problem of mould service efficiency.Operation for example in patent 201110077316.7 described in embodiment
Technique is：5) veneer gluing and assembly (1) gluing this experiment of agent prescription modified urea-formaldehyde glue are used as adhesive .... (2)
Applying glue, assembly cold pressing one side resin added for 150g/m2.Stacked by board using poplar board machine direction generally parallel orientation during assembly.
6) time of colding pressing is 1 hour, then after colding pressing to be put into press after the slab arrangement for forming assembly of colding pressing is neat ... ...
The die-filling fixation of laminated veneer lumber flitch.7) maintenance will be die-filling after flitch feeding temperature be 35~45 DEG C, relative humidity be 65~
75% fog room, conserves 90~100 hours.8) before form removal form removal, laminated veneer lumber flitch must be placed at ambient temperature
More than 10~12 hours；During form removal, flitch screw everywhere should be uniformly unloaded simultaneously.
By process above as can be seen that the method glue-spread is big, serious formaldehyde will be brought；And need 35~
The time of 5 days or so is conserved in 45 DEG C of greenhouse, the production cycle is long, and mould takes many.
In patent 201410835789.2, burst size of methanal Con trolling index is≤5.0mg/L, can only achieve E2 grades of water
It is flat.
And in patent 201620814134.1, although also refer to a kind of method of formaldehydeless Recombinant Wood, but the practicality
The Recombinant Wood of new making is by density flaggy, wood single-plate layer, transparent anti-corrosion enamelled coating, transparent wear, thermoplastic resin sheet
Deng composition, can be seen that this from its composition material is really the compound plate construction of a kind of new density board, veneer, it is impossible to
For the reprocessing in traditional science wood meaning.
The content of the invention
It is of the invention main using the non-formaldehyde system adhesive with room temperature fast-curing performance, thoroughly solve the first of Recombinant Wood
Aldehyde discharges problem, while shortening the molding curing time of scientific and technological flitch, improves operating efficiency, is saved by accelerating mold turnover
Investment-saving.
The technical proposal of the invention is realized in this way：
1st, from solids content it is high, can be with cold curing, the non-formaldehyde system water-based isocyanate with excellent bonding strength（EPI）
Class, polyurethane（PUR）The adhesive of one or more mixtures in class, epoxy resin tackifier；
2nd, the veneer that will be put in order is by two-sided 90-130g/m2Glue-spread gluing layer by layer, mutually put down by board using poplar board machine direction
Capable direction stacks assembly；
3rd, the slab for forming assembly arrange it is neat after be put into press, the time of colding pressing for 1 hour, the laminated veneer lumber after colding pressing
The die-filling fixation in side；
4th, more than the 35 DEG C maintenances of flitch after die-filling are not less than 24 hours, less than 35 DEG C maintenances are not less than 48 hours；
5th, after the flitch after mould unloading is through butt, deburring, by the size of design and direction slicing or it is sawed into required scientific and technological wood skin.
Employ above-mentioned technical proposal the beneficial effects of the invention are as follows：
The present invention relates to a kind of production technology of formaldehydeless scientific and technological wood skin.Present invention process is simple, and is processed through the processing step
Wood skin, more common Recombinant Wood wood skin has safety non-toxic, formaldehydeless release；Clamp time is short, production efficiency is high, can be significantly
The advantages of reducing mould investment.
Specific embodiment
Specific embodiment of the invention is as follows：
Embodiment：A kind of production technology of formaldehydeless scientific and technological wood skin, now using Dongying Shengji Environmental Engineering Co., Ltd.
As a example by the poplar material science and technology wood skin production technology of YJ-122 water-thinned isocyanate adhesives, the technique specifically includes following step
Suddenly.
1st, by rotary-cut board using poplar board drying or dry and reach moisture content 8-16%, repaiied according to corresponding repair technology
Benefit is used to remove defect.
2nd, YJ-122 water-thinned isocyanate adhesives are pressed into host：Curing agent=100：The ratio of 8-10 is well mixed.
3rd, the veneer that will be put in order on four rollers glue spreader double spread layer by layer, glue-spread presses veneer thickness and veneer is aqueous
Rate is controlled in two-sided 90-130g/m2, the appropriate increasing glue-spread that veneer thickness is big, moisture content is low.
4th, the slab for forming assembly arrange it is neat after be put into press, the time of colding pressing for 1 hour, the ply after colding pressing
The die-filling fixation in building blocks side.
5th, the flitch after die-filling is conserved for more than 35 DEG C and conserved 48 hours for 24 hours, less than 35 DEG C.
6th, after the flitch after mould unloading is through butt, deburring, by the size of design and direction slicing or it is sawed into required science and technology
