Abstract
The invention discloses a production method for a large-bending plywood. The production process includes: material choice, curing, rough forming, shaping, sequential arrangement and glue application, curing, prepressing, hot pressing, smoothing, curing and edge cutting. By means of the process, the maximum transverse bending of the plywood is 360 degrees and the maximum longitudinal bending of the plywood is 180 degrees under the action of external force. Under the action of external force, the plywood has high toughness and cannot be easily broken, no matter whether the plywood is bent or curved. The plywood does not need to be fixed and shaped by a bending die at all, and can be bent at any time. The whole plywood is attractive and environment-friendly; the plywood is a preference for construction, art and decoration; because loose and tight sides are sequentially arranged, glue and shaped boards can be perfectly combined, and the glue can be firmly solidified, and has high bonding strength.
Description
Technical field
The invention discloses a kind of glued board, that be specifically related to is the preparation method of the high macrobending degree glued board of a kind of suppleness.
Background technology
Glued board is to be peeled into veneer or to be become veneer by the flitch slicing by juggle, sticks with glue three layers or the board-like material of multilayer that the agent gummed forms again, usually uses the odd-level veneer, and the orthogonal gummed of machine direction of adjacent layer veneer is formed.In the decoration of family or public place, be widely used, substitute other materials with superior performance.Common glued board especially at the art work, in the use procedure in the ornamental industry, when the structure with radian is used, need to go with the glued board of monolithic splicing in the process of using, so just wasted a large amount of resources.Common way is at the panel of twisted plate and base plate the slit to be set, and under the condition of external heat, makes it softening, bending forming then, and the aforesaid operations pattern can reach crooked effect, but is provided with the seam line at panel, the aesthetic property that impact is whole.The patent No. be 200910095816.6 the name be called a kind of twisted plate and manufacture method thereof, technical scheme is original
Summary of the invention
The present invention provides a kind of arbitrarily preparation method of crooked macrobending degree glued board according to above-mentioned deficiency.
For achieving the above object, technical scheme of the present invention is a kind of preparation method of macrobending degree glued board, and its manufacturing process comprises:
1) selection: choose poplar and birch, make the central layer that thickness is 8.8mm, for subsequent use after the oven dry; The drying time of central layer is 2 minutes, and temperature is 95～120 ℃ during oven dry, and making its central layer moisture content is 16%;
2) health: the central layer in the step 1 is placed under the dry indoor environment, left standstill 2 days; Then central layer is carried out sorting, choose loose side and tight face, with the location loose side of coarse texture, opposite be decided to be tight face;
3) blank moulding: use the automatic plate-splicing machine splicing, make three plates form the integral body without connecting sewing;
4) typing: with stone compacting 10～12 hours, make its typing;
5) ordering gluing: the stereotype plate in five steps 4 is arranged sequentially, coat double faced adhesive tape for from top to bottom second and the 4th; Put in order and be
6) health: be placed under the dry indoor environment, left standstill 6～8 hours;
7) precompressed: be 1.4～1.6Mpa preformer by pressure, precompressed makes its moulding;
8) hot pressing: be 90～100 ℃ of hot press hot pressing 5～8 minutes by temperature;
9) shaping: smear putty at the plate face, make it smooth;
10) health: be placed under the dry indoor environment, left standstill 1～1.5 day;
11) cutting edge: be cut into as required the size that needs.
It is 2.5～2.7m that three plates in the described step 3 form the length without the integral body of connecting sewing, and wide is 1.2～1.4m.
Stone evenly is compressed on by on the spliced plate face of step 3 in the described step 4, adds upper padding plate between plate face and stone.
Five stereotype plates put in order and are any combination of poplar and birch in the described step 5.
Be four horizontally-arrangeds during the ordering of described five stereotype plates, a vertical setting of types.
Double faced adhesive tape in the described step 5 is CARB2.
Squeeze time is 45 minutes～1 hour in the described step 7.
By the beneficial effect after the technique scheme be:
1) under external force, laterally maximum deflection 360 is spent, vertically maximum deflection 180 degree;
2) under the effect of external force, no matter be crooked or the circle song, toughness is high, not easy fracture;
3) fully fixed-type without bending die, can be crooked at any time;
4) overall appearance, environmental protection; For building, art is used and ornamental first-selection;
5) adopt putting in order of degree of tightness face, can be so that the perfect adaptation of glue and qualitative plate, so that glue curing is firm, bonding strength is large;
6) adopt the repetition health promotion technology, so that the toughness of profiled sheeting progressively increases.
The specific embodiment
The present invention is further illustrated below in conjunction with the specific embodiment.
Embodiment one:
A kind of preparation method of macrobending degree glued board, its manufacturing process comprises:
1) selection: choose poplar and birch, make the central layer that thickness is 8.9mm, the drying time of central layer is 2.5 minutes, and temperature is 95 ℃ to make its central layer moisture content be 17% during oven dry, and is for subsequent use after the oven dry;
2) health: the central layer in the step 1 is placed under the dry indoor environment, left standstill 2～3 days;
3) blank moulding: use the automatic plate-splicing machine splicing, make three plates form the integral body without connecting sewing; It is 2.5m that three plates form the length without the integral body of connecting sewing, and wide is 1.2m;
4) typing: with stone compacting 10 hours, make its typing; Stone evenly is compressed on by on the spliced plate face of step 3, adds upper padding plate between plate face and stone; In the process of compacting, keep temperature unchanged;
5) ordering gluing: the stereotype plate in five steps 4 is arranged sequentially, be poplar, birch, poplar, birch, poplar successively, wherein the poplar plate of middle centre vertically discharges, and remaining four blocks of plate laterally discharges; Coat CARB2 glue for from top to bottom second and the 4th;
