Description
Technical field
The present invention relates to dalle production technical field, espespecially a kind of anti-surface checking synchronous grain-matched veneered plywood
Manufacture method.
Background technology
Synchronous grain-matched face artificial board is true to nature with its texture, natural, the characteristics of have the imitative wood texture of embossment three-dimensional touch
Increasingly favored by market.Synchronous grain-matched decoration panel is by synchronous grain-matched equipment and device, in veneer, by steel form
On texture with dipping paper on decorative pattern texture it is synchronous laminating, present synchronization stereo relief effect.
Current domestic production technical elements, application of the synchronous grain-matched facing technology on MDF and particieboard very into
Ripe, existing technology typically uses the short period production technique of high temperature, but with MDF and particieboard these industrialized productions
Plate kind is different, and domestic plywood production is essentially all manual operations at present, and glued board itself is present as veneer drying is aqueous
The natural characteristic such as rate is uneven, wood skin is expanded with heat and contract with cold greatly, anisotropy is big, synchronous grain-matched veneered plywood can only use low temperature week long
The facing production technology of phase, the production time is long, and efficiency is low, and this significantly impacts the production efficiency of synchronous grain-matched glued board.Meanwhile,
The synchronous grain-matched veneered plywood of prior art production is easily subject to surface checking caused by climatic effect, and such as south uses synchronous
Easily there is cracking to the north, particularly northeast or northwest to the furniture of decorative pattern face plywood making, limit synchronous grain-matched
The use scope of veneered plywood.
The content of the invention
To solve the above problems, the present invention provides a kind of manufacture method of anti-surface checking synchronous grain-matched veneered plywood,
The production efficiency of synchronous grain-matched veneered plywood can effectively be improved, at the same solve synchronous grain-matched veneered plywood surface intolerant to
The technical problem of cracking.
To achieve the above object, the technical solution adopted by the present invention is：A kind of anti-surface checking synchronous grain-matched facing is glued
The manufacture method of plate, comprises the following steps：
A. plywood substrate is cut out and is sawn into and fiberboard identical size；
B. sanding surface treatment is carried out to plywood substrate and fiberboard；
C. the plywood substrate after sanding carries out colding pressing displaying treatment using compound gummed paper and fiberboard assembly after assembly；
D. the slab after displaying of colding pressing is put into hot press and carries out that hot pressing is compound to obtain semi-finished product；
E. the semi-finished product after being combined to hot pressing carry out fixed thick sanding and cut out saw, and then edges of boards are repaired；
F. semi-finished product are synchronized using impregnated bond paper and line is overlayed, its press-paste technique parameter is：130 DEG C~180 DEG C of temperature,
Pressure 13MPa~20MPa, time 60s~180s.
Specifically, plywood substrate before cutting out saw also needs that surface should be carried out to mend putty treatment, and fiberboard book size is
2460mm*1240mm, thickness is 0.8mm~1.2mm.
Specifically, the vacuum sander employed in step B carries out sanding treatment to plywood substrate and fibreboard surface,
Sanding belt mesh number is 180 mesh or 240 mesh, and dedusting soot blower is provided with sander ejecting plate.
Specifically, the compound gummed paper in step C uses thermosetting resin impregnated paper, technical requirements：Impregnation resin content 140~
160%th, volatile content 6~8%, procuring degree 40~60%, burst size of methanal≤1.5mg/L.
Specifically, being colded pressing in step C, it is as follows to display technological parameter：Pressure 5MPa~8MPa, the time is not less than 1h and does not surpass
Cross 8h；Plywood substrate overlaps with each side of fiberboard and aligns during assembly, and assembly dislocation is no more than 2mm.
Specifically, the hot pressing combination process parameter in step D is as follows：8 MPa of pressure~14MPa, temperature 120 DEG C~145
DEG C, time 350s~450s.
The beneficial effects of the present invention are
1. the top layer of plywood substrate is carried out by decoration treatment using relatively thin fiberboard, neither influence the edges of boards of veneered plywood
Outward appearance, while solving technical barrier of the synchronous grain-matched veneered plywood surface intolerant to cracking, expands synchronous grain-matched facing glue
The use scope of plywood product；
2. plywood substrate top layer is processed, made synchronous grain-matched veneered plywood hot pressing time from existing 300s~480s
180s, or even 60s are foreshortened to, production efficiency is substantially increased, production cost is reduced.
