Specific embodiment
The present invention provides a kind of complex methods of PMMA plate, comprising the following steps:
One layer of PMMA film of folder patch, successively carries out fusion and cooling shaping, obtains composite plate between adjacent PMMA plate；Institute
Stating PMMA plate is PMMA transparent panel or PMMA autochromatic plate, and the PMMA film is PMMA transparent membrane or PMMA colorful film.
In the present invention, the total quantity of the PMMA plate is preferably greater than or equal to 2 pieces, i.e., the method for the present invention can by two pieces or
The compound composite plate for obtaining different-thickness of muti-piece PMMA plate.In the present invention, the thickness of the PMMA plate is independently preferably 2
~50mm.The present invention preferably selects the thickness of the PMMA plate respectively according to the thickness of final required composite board, with two pieces
PMMA plate it is compound for: the composite board as needed for final with a thickness of 13mm, then the thickness of two blocks of PMMA plates can divide
It Wei not 3mm and 10mm；The composite board as needed for final with a thickness of 17mm, then the thickness of two blocks of PMMA plates can be respectively
5mm and 12mm.In the present invention, the PMMA plate is PMMA transparent panel or PMMA autochromatic plate.The present invention is transparent to the PMMA
The source of plate or PMMA autochromatic plate does not require particularly, is using PMMA transparent panel well known in the art or PMMA autochromatic plate
It can.Two pieces of different-thickness or muti-piece PMMA plate are combined with each other by the present invention as required, can customize answering for various thickness
Plywood material.
In the present invention, the thickness of the PMMA film is preferably 0.2~0.3mm, more preferably 0.2mm.In invention,
The size of the PMMA film is preferably identical as the size of the PMMA transparent panel.In the present invention, the PMMA film is
PMMA transparent membrane or PMMA colorful film.The present invention is using PMMA film as a kind of unique chemical crosslinking medium, by two pieces
Or muti-piece PMMA plate is combined with each other, and forms the plate of target thickness, because of the thickness very little of the PMMA film, relative to multiple
The thickness of plywood material can be ignored；And PMMA film and PMMA plate can be transparent or colour, by compound
PMMA transparent composite sheet, PMMA colour composite plate or the double-colored composite plate of PMMA of available different-thickness.With two blocks of PMMA plates
It is compound for: when the PMMA film and two blocks of PMMA plates are transparent, gained composite plate be PMMA transparent composite sheet；When
When the PMMA film and two blocks of PMMA plates are same color, gained composite plate is PMMA colour composite plate；When described two
Block PMMA plate be different color or one piece be it is colored, when one piece is transparent, gained composite plate is the double-colored composite plate of PMMA.At this
In invention, the color of the PMMA film and PMMA plate can carry out multicolour combination according to actual needs, to generate not
Same colouring effect.In the present invention, the PMMA film preferably passes through extrusion film technique and PMMA forms a film, and carries out to film
Sandization processing in surface obtains；The method that the present invention handles the extrusion film technique and surface sandization is not wanted particularly
It asks, using method well known in the art.
In the present invention, the temperature of the fusion is preferably 105~150 DEG C, and more preferably 130~140 DEG C, pressure is preferred
For 0.9~1.2MPa, more preferably 1.0MPa；The time of the fusion is preferably 45~50min, more preferably 50min.At this
In invention, the fusion is preferably carried out using compound press, i.e., the PMMA plate that folder posts PMMA film is sent into compound press,
Compacting fusion is carried out under the conditions of above-mentioned temperature and pressure.The present invention does not require the compound press particularly, using ability
Compound press known to domain.
In the present invention, the cooling preferably uses 18~25 DEG C of cooling water to recycle in the plate face of the compound press
Method carry out, so that PMMA plate through high-temperature fusion is shaped and do not rebound, fusion is integral.In the present invention, the PMMA plate with
PMMA film is similar polymer substance, is fused together after being suppressed by compound press, the composite plate obtained after cooling shaping
It will not show apparent lamination, and the case where be not in cracking, will not influence the appearance and usability of PMMA plate
Energy.The complex method period provided by the invention is short, and production is quick, and the same day can go out finished product, and a plate can also be switched on production, and
Various thickness and color are customizable.
The present invention provides the PMMA composite plates that complex method described in above scheme obtains.PMMA provided by the invention is compound
Plate can be PMMA transparent composite sheet, PMMA colour composite plate or the double-colored composite plate of PMMA of different-thickness, i.e. the present invention provides
PMMA composite plate can carry out different settings according to reality for the needs of plate thickness and color effects.For example, working as institute
When to state PMMA film and two blocks of PMMA plates be transparent, the composite plate is PMMA transparent composite sheet；When the PMMA film and
When two blocks of PMMA plates are same color, the composite plate is PMMA colour composite plate；When two blocks of PMMA plates are difference
Color or one piece be it is colored, when one piece is transparent, the composite plate is the double-colored composite plate of PMMA；Wherein, the PMMA plate
Thickness, which can according to need, makees different settings, and then obtains the PMMA composite plate of different-thickness, different color effect.
It is carried out specifically below with reference to complex method and PMMA composite plate of the embodiment to PMMA plate provided by the invention
It is bright, but they cannot be interpreted as limiting the scope of the present invention.
