Description
[technical field]
The utility model relates to building materials and ornaments technical field of membrane, specifically a kind of heatproof has the bright film of metallic luster.
[background technique]
Currently, no matter the aluminizer of PVC or PET is widely used, but directly plating binding force of membrane is poor, in order to improve combination
Power needs first to do prime coat, and not only construction is troublesome in this way but also considerably increases cost.
Although existing vacuum coating technology is mature but the binding force of basement membrane and aluminium is bad, and later period use makes to be easy color aluminium
Layering is coated with one layer of resin layer, during being coated with resin layer if it is desired to improving binding force needs the first bottoming on basement membrane
Film is easily deformed, and especially PVC film deformation ratio is larger, is applied directly to above PVC, by baking oven be easy by film forming deformation or
It is stretched.Increase process loss to be also easy to produce, therefore causes higher cost.Aluminium layer scratches straight plated film in order to prevent, needs to increase again
Add protective layer.The protective layer is also required to selection and the good protective layer of aluminium binding force, and it is less to can satisfy the protective layer used, promotes
Property is poor.Later period film needs Compound Machining also to need a series of problems, such as considering heatproof, flexibility, adhesive force, caking property.
[summary of the invention]
The purpose of this utility model seeks to solve above-mentioned deficiency and providing a kind of heatproof has the bright film of metallic luster.It should
Structural membrane both can solve the problem of binding force of aluminium layer without the bottoming on basement membrane.The metallic luster of the production simultaneously
Bright film has the characteristics that temperature tolerance flexibility, can substitute metal Soft Roll, in the flexible package for anti-metallic luster.
Designing a kind of heatproof to achieve the above object has the bright film of metallic luster, which includes successively compound from bottom to top
PVC/PET film substrate layer 1, composite layer 2, aluminium layer 3 and UV protective layer 4, the PVC/PET film substrate layer 1 with a thickness of
50-300um, for composite layer 2 with a thickness of 6-20um, the aluminium layer 3 is vacuum aluminium coated layer, with a thickness of 300-600 angstroms, the UV
Protective layer 4 is with a thickness of 2-20um.
The UV protective layer 4 is using epoxy resin, aliphatic polyurethane resin or the phenolic resin of modification.
Compared with the existing technology, structure is simple for the utility model, novel, can using composite layer and aluminium layer composite construction
With the binding force problem of effective solution aluminium layer and resin, the selection space of resin or coating is bigger, without on basement membrane
Face bottoming.The bright film of the metallic luster of the production simultaneously has the characteristics that temperature tolerance flexibility, can substitute metal Soft Roll, be used for
In the flexible package of anti-metallic luster.In addition, the production method of the utility model is at low cost, manufacture craft is simple, moreover it is possible to meet dress
Adorn the performance requirement used, use easy to spread.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1, PVC/PET film substrate layer, 2, composite layer, 3, aluminium layer, 4, UV protective layer.
[specific embodiment]
As shown in Figure 1, the utility model includes successively compound PVC/PET film substrate layer 1, composite layer from bottom to top
2, aluminium layer 3 and UV protective layer 4, the PVC/PET film substrate layer 1 is with a thickness of 50-200um, and composite layer 2 is with a thickness of 6-
20um, the aluminium layer 3 is vacuum aluminium coated layer, and with a thickness of 300-600 angstroms, the UV protective layer 4 is with a thickness of 2-20um.The UV
Protective layer 4 is using epoxy resin, aliphatic polyurethane resin or the phenolic resin of modification.
The preparation method of the utility model, comprising the following steps:
(1) substrate PVC/PET film, thickness 50-300um are selected；
(2) by complex method, one layer of vacuum aluminium coated layer, the vacuum aluminium coated layer system are shifted on PVC/PET film
Preparation Method: really plating one layer of aluminium on the BOPP film of transfer, coats compound adhesive in aluminium surface, then multiple with PVC/PET film
: 6-20um is closed, composite layer thickness baking temperature: 80-120 DEG C, to remove after placing a period of time, the aluminium in the BOPP film
Layer is transferred to above PVC/PET film by compound adhesive；BOPP film removing after transfer can continue recycling of aluminizing, only
Permanent stain is had damage or occurred to surface.Adhesive and aluminium can be made to be bonded in one by chemical reaction by the complex method
It rises, has well solved the binding force of aluminium layer and coating.And PVC/PET film requires no baking oven, reduces the change of former film
Shape.
(3) compound good film passes through 50 DEG C, and placement in 24-48 hour cures, and keeps resin in compound adhesive and aluminium completely anti-
Ying Houzai is peeled away, and shifts the aluminium layer containing metallic luster, aluminum layer thickness: 300-600 angstroms after removing above PVC/PET film；
(4) finally, the coating can be with effective protection metal watch in one layer of light UV protective coating of aluminium layer face upper surface construction
Face, the UV protective coating main structure can be epoxy resin, aliphatic polyurethane resin, phenolic resin of modification etc..Resin
Selection can make oiliness also and can choose it is aqueous.It can under the action of UV illumination monomer resin and matrix resin are in initiator
Fully crosslinked reaction.Coating layer thickness 2-20um, the rigidity and intensity of the usual inclined thick film of thickness increase, but its reduction of pliability.UV
Fluorescent tube irradiation time 1-3 seconds, it can solidify, if the too long film of irradiation time deforms or xanthochromia.
In the step (2), compound adhesive is composite adhesive resistant to high temperature, the component of the adhesive by weight: poly- ammonia
The polyol blends 20-35% of ester, isocyanate curing agent 5-10%, water content are less than the ethyl acetate 20- of 300ppm
35%, butanone or acetone 20-35% of the water content less than the butyl acetate 10-30% of 300ppm, water content less than 300ppm and
Water content be less than 300ppm cyclohexanone 10-25%, total amount mixing time 0.5-1h after mixing, 25 DEG C of room temperature, viscosity 15-40S
(applying 4 glasss).Composite adhesive coats thickness of dry film: 6-20um；The generally low coating glue thickness of PVC surface roughness is with regard to thin, PVC
Rough surface glue is just thick, can be shifted completely with compound rear aluminium layer as standard.Wherein the ratio of curing agent more high rigidity is better,
Flexibility is poorer.
The utility model is simultaneously not limited to the embodiments described above, and other any spirit without departing from the utility model are real
Made changes, modifications, substitutions, combinations, simplifications under matter and principle, should be equivalent substitute mode, be included in practical
Within novel protection scope.
