Description
Technical field
The invention belongs to Bamboo Formwork manufacture field, specially a kind of production technology of bamboo embryo frosting hot press composite board.
Background technology
Existing timber intensity, hardness, density and the flatness property taken into account are poor, and repeat usage is low.And sheet material is more with solid wood board
Or bamboo clappers compacting is formed, its consumption to timber is larger, because substantial amounts of wood-based planet is used so that the forest reserves are more
It is deficient.And the regeneration period of bamboo is shorter, and its Wood density and hydrophobicity are superior to timber, therefore consideration uses bamboo
Panel replaces wood plank.
Existing build concrete template generally uses plank sheathing or aluminum template, wherein plank sheathing usage cycles to compare
It is short, pile up rough, it is non-watertight；Using aluminum template, and structure bulky, and high cost.
And have a kind of existing Bamboo Formwork, it is used by the way of the formable layer plastics of glue Surface Mount one using bamboo core plate surface,
This kind of mode template thickness is difficult to unanimously, and easily height rises and falls, and the surface that corresponding concrete lining is formed is not bright and clean flat enough
It is whole, it is necessary to secondary construction, more time-consuming, its popularization is unsatisfactory.To find out its cause, mainly this kind of Bamboo Formwork is used
During moulding plastics plate and bamboo core plate carry out adhering and pressing, the plastic plate bamboo core plate that do not rain is merged, bamboo core plate table
Height on face rises and falls and therefore appear to plastic sheet surface；If reinforcing compacting is carried out in adhesion process, in pressing process
The finish of frosting can be damaged, it is also unfavorable for later stage engineering construction.
Because there is finish and thickness in above plastics Bamboo Formwork, it is contemplated that process innovation is carried out, to add
It is fast to promote Bamboo Formwork product, save engineering cost, final service society.
The content of the invention
The purpose of the present invention is directed to problem above, there is provided a kind of production technology of bamboo embryo frosting hot press composite board,
Creatively propose carries out the mode of thermal-adhering before plastic plate goes out mold forming with bamboo core plate so that plastics can do with bamboo core plate
To mutually fusion, compound effect is realized, its thickness is uniform, and surface smoothness is higher, while also saving cost.
To realize object above, the technical solution adopted by the present invention is：A kind of life of bamboo embryo frosting hot press composite board
Production. art, comprises the following steps：

Specific embodiment
In order that those skilled in the art more fully understand technical scheme, the present invention is entered below in conjunction with the accompanying drawings
Row is described in detail, and the description of this part is only exemplary and explanatory, should not there is any limitation to protection scope of the present invention
Effect.
A kind of production technology of bamboo embryo frosting hot press composite board of the present invention, comprises the following steps：
（1）, curtain processed：Bamboo embryo core plate, drying to moisture content≤8% are compiled into the bamboo chip of thickness≤1mm；
（2）, gluing：Bamboo embryo core plate face to be composite after drying is carried out into gluing, rubberization thickness is 1mm-4mm；
（3）, hot-extrudable plastic plate：Using high molecule plastic extrusion molding thickness≤6mm offset plates；
（4）, cladding plate：By step（2）In bamboo embryo core plate glue surface be placed on step upward（3）In gum outlet at,
Treat step（3）In plastic plate depanning after be covered in immediately on the bamboo embryo core plate after gluing；
（5）, customized cut-off：After plastic plate is all covered on bamboo embryo core plate, the modeling being connected with discharging opening is cut off by cutting knife
Flitch；
（6）, hot-rolling pressure：Bamboo embryo core plate after plastic covering plate is sent into hot press, is rolled under HTHP；
（7）, trimming：Step（6）Trimming is carried out after the completion of middle rolling, packaging and warehousing after final products is formed.
Preferably, the high molecule plastic is PVC or PP or PE.
Preferably, in step（6）The environment temperature used in hot nipping process is 130 DEG C -145 DEG C, hot-pressing roller 70 it is pre-
Pressure is 500 tons, and the roll-in time is 2min-3min.
Preferably, in step（4）In cladding plate operating process, be in overlying plastic plate by plastic extruding head 80 extrude after,
Extrusion plastic plate 83 is formed, is laid in after inverse bending immediately on bamboo embryo core plate 90, then the bamboo embryo core plate of lower floor continues to modeling
Flitch extrudes the counter motion in direction, and it is specific as shown in Figure 2.
Using complex method of the present invention, as shown in fig. 1, plastics are extruded by plastic extruding head 80, in extrusion roller 81
Under be shaped to extrusion plastic plate 83, be then laid on bamboo embryo core plate 90；This is a kind of mode directly mated formation；But more there is choosing
Flooring mode should be by the way of shown in Fig. 2.
Cut off by cutting knife 82 after the completion of cladding plate, then moved to below hot-pressing roller 70 in the presence of supporting table 84
Carry out roll-forming.Because the surface of bamboo embryo core plate 90 can have surface groove as shown in Figure 3 91, so traditional jointing plate
Easy degumming and became uneven is even, and after using manufacture craft of the invention, plastics can before the forming under thermal pressure effect
It flow at surface groove 91, is formed 92 at filling, is formd between such extrusion plastic plate 83 and bamboo embryo core plate 90 organically
Combination, residual stress is small between plastics and bamboo embryo core plate, and realizes two kinds of mutual fusions of material, while the thickness of product
Uniformly.
As shown in figure 4, another cladding plate process schematic, 90 degree of the plastic plate bending in present invention process production process
It is laid in after inverse bending afterwards on bamboo embryo core plate, counter motion of the bamboo embryo core plate towards laying direction.After such plastic plate extrusion
Bending is laid on bamboo embryo core plate, facilitates bamboo embryo core plate along extrusion plastic plate counter motion, will not be limited by extrusion equipment
System, mating formation can more facilitate arbitrarily, and operation is simple.
Using a kind of production technology of bamboo embryo frosting hot press composite board of the invention, creatively propose in plastic plate
Go out before mold forming to be carried out with bamboo core plate the mode of thermal-adhering so that plastics can be accomplished mutually to merge with bamboo core plate, realize compound
Effect, its thickness is uniform, and surface smoothness is higher, while also saving cost.
