Embodiment
See Fig. 1 and Fig. 2, the utility model relates to the material of a kind of PUR, cellular sandwich, coextruded plastic plate compound, wherein PUR(urethane) it is a kind of polymkeric substance with carbamate segment repeated structural unit being made up of isocyanic ester and polyol reaction, this kind of material is composited by coextruded plastic plate 1 and cellular sandwich material about 2.
Described coextruded plastic plate 1 comprises two layers or trilaminate material, two layers or trilaminate material pass through vacuum thermoforming, form coextruded plastic plate 1, the thickness of described coextruded plastic plate 1 is 1.5mm ~ 2mm, the material proportion of coextruded plastic plate 1 is 1.1g/cm3, coextruded plastic plate 1 has anti-zoned wound, shock resistance, uvioresistant and resists anti-ageingization and weathering resistance performances such as fading, and the feature of environmental protection is good, puts into the counterdie (die) heated after coextruded plastic plate 1 is shaping.
In described coextruded plastic plate 1 two layers or three laminate material are resin material, and when coextruded plastic plate 1 is materials at two layers, coextruded plastic plate 1 is followed successively by PMMA, ABS from outside to inside, or ASA, ABS, or AES, ABS; When coextruded plastic plate 1 is trilaminate material, coextruded plastic plate 1 is followed successively by PMMA, ASA, ABS from outside to inside, or PMMA, PC, ABS, or ASA, PC, ABS.
ASA is made up of the warm and fine divinyl rubber of propylene, has the physicals that ABS is extremely good, very strong weathering resistance and resistance to elevated temperatures.
AES(vinyl cyanide-EPDM rubber-styrol copolymer) there is extremely good weathering resistance, even if being exposed to outdoor ultraviolet, humidity for a long time, drenching with rain, illumination and when ozone, physical property can also be kept to stablize without application.
Wherein PMMA is again acrylic, and it is polymethylmethacrylate, is commonly called as synthetic glass, and it is transparent material, it is possible to make coextruded plastic plate 1 remove the step painted on the surface from, and PMMA plate can be mixed and adjust into abundant color with not homochromy mother, it is achieved part exempt from paint.
Described cellular sandwich material 2 is paper wasp nest, PP honeycomb or aluminium honeycomb, the outside surface of this cellular sandwich material 2 is coated with glass felt, the spraying of glass felt surface also fully infiltrates and puts into die cavity conjunction mould curing molding after urethane, thus form glass felt and PU mixture layer 2.1 in the upper and lower surface of cellular sandwich material 2, the thickness of cellular sandwich material 2 is 5 ~ 10mm, the counterdie (die) of PHC technique (sandwich forming technique) put into by cellular sandwich material 2, upper and lower mould is closed mould curing molding, the glass felt at described cellular sandwich material 2 top and PU mixture layer 2.1 are just compounded in the bottom of coextruded plastic plate 1, thus it is combined into complete matrix material.
The production method of the material of this kind of PUR, cellular sandwich, coextruded plastic plate compound is as follows:
One, upper plate: laminated plastics plate is put into Packing Machine inner sandwiched frame, mould is placed in Packing Machine lifting work platform, and mould is aluminum alloy mould or ring oxygen mould, this mould has and vacuumizes hole.
Two, bubble is blown in heating: plastics suction mould and sheet material being heated respectively, Heating temperature is 150 ~ 170 DEG C, treats that plastic plate softens, subsequently it is blown bubble.
Three, vacuumize: mould rises to table top, from vacuumizing hole, mould inside is vacuumized so that it is inner vacuum degree is 0.08 ~ 0.1MPa, softening sheet material is adsorbed on mould.
Four, cooling and shaping: blow a cold wind over the plastic plate cooling and shaping of vacuum thermoforming, forms work in-process.
Five, drawing and forming: when cellular sandwich selects paper wasp nest, it may also be useful to honeycomb paper is stretched to specified dimension by honeycomb paper drawing machine, honeycomb hole is positive hexagon, (PP honeycomb, aluminium honeycomb are without the need to this operation)
Six, glass felt is coated: by cellular sandwich Surface coating glass felt.
Seven, mold heated: heated by the upper and lower mould of composite die, counterdie (die) heating temperatures is to 60 ~ 70 DEG C, and patrix (punch) heating temperatures is to 100 �� 5 DEG C.
Eight, work in-process insert die cavity: work in-process plastic plate is put into counterdie.
Nine, spraying polyurethane: mechanical manipulator captures coated good cellular sandwich, moves and starts to spray PU layer to nozzle position, carries out the upset spraying of tow sides, thus allow PU be sprayed on glass surface, and infiltrate glass, enter in the honeycomb hole of honeycomb, and make glass felt fully infiltrate urethane.
Ten, mould curing molding is closed: upper and lower mould is closed mould, and the press dwell time is 4min, forms complete matrix material after having solidified.
The matrix material made by this kind of production method and the performance comparison of traditional pure plastic plate are such as following table:
| Flexural strength | Modulus in flexure | Weight per unit area | |
| Pure plastic plate (5mm) | 51.4MPa | 1456MPa | 5500g/m2 |
