A kind of pellicular front is coated with
Technical field
The utility model relates to a kind of application layer technology of product surface, especially relates to a kind of clear, colorless of the UV of comprising strengthened coat or coloured heat transfer film, is coated with to substitute conventional spray paint formula face.
Background technology
Face be coated be meant the top layer of object one to coating, play protection and effect attractive in appearance, the processing mode that the most often uses is spraying and brushing; Because it is a kind of coating of liquid state that the face of normality is coated with, processing mode is spraying and the brushing that is exposed to atmosphere again, and be solidified with certain consuming time be to be exposed in the atmosphere, long more open-assembly time consuming time is long more.Therefore; The bad defective of appearance can take place; Like dirt pits, soft flocks, water .... or the like the pollutant that normality exists in the atmosphere stain; Long-pending oil (because of the reason of fluid tension causes bad greater than integral thickness of edge and hole editorial afterword degree), the sagging bad order of the mobile surface orientation striped that causes too greatly (too low or) because of paint viscosity; Orange peel (the too high or relatively poor surface that causes of levelability is just like the bad order of orange peel because of paint viscosity), bubble, shrinkage cavity ... .. or the like bad causes that yield reduces, cost increases, and causes the pollution of a large amount of organic solvents simultaneously; Powder body coating also together.
After the existing traditional hot transfer printing processing, because transfer printing rete intensity difference so the aspect that will spray again is coated with the effect with the protection transfer film, causes yield to descend (spraying bad) problems such as cost increase, environmental pollution.
Coating has solvent in forming, and the solvent that in spraying process, uses is more, and the most of coating that uses in market is oiliness, and it means that its solvent is an organic solvent, its meeting health risk, contaminated environment.Heat curing coating, the baking of must heating could be solidified, and especially the coating of high temperature ability heat cure for a long time consumes energy greatly, and is unfavorable to environmental protection.Because spraying process space-pollution risk is bigger, thus must execute work at dust free room, the big and power consumption of its investment, unfavorable to environmental protection.Spraying coating process consumption coating is big, and the coating of theoretical availability < 60%, its meaning has>40% is wasted, and therefore, cost is higher and unfavorable to environmental protection.
The utility model content
The utility model is the defective that exists to the above-mentioned background technology, provides a kind of pellicular front to be coated with, and changes traditional application (spraying and brushing) mode into coating method processing, pollutes and power consumption to save the coating cost, to reduce.Use the UV coating that hangs down solvent or do not have flux, reduce pollution and consume energy, the increase production capacity.
For realizing above-mentioned purpose, the utility model discloses a kind of pellicular front and be coated with, comprise plastic sheeting, introduce one deck UV face on the plastic sheeting and be coated with rete, be coated with at the UV face and introduce one deck PUR on the rete; Plastic film thickness is 0.01~1mm, and it is 0.01~1mm that the UV face is coated with thicknesses of layers, and PUR thickness is 0.01~1mm.
Further, said PUR applying workpiece, the UV face is coated with rete and exposes surface of the work; It is ultraviolet-curing paint or first heat cure two UV curing photocureable coating of solidifying of UV again that the UV face is coated with rete; Plastic sheeting adopts all types of light-passing plastics such as PET, PC, PVC, PEVA, EVA and OPP, and PUR is become to be grouped into by basic resin, tackifier, viscosity modifier and antioxidant etc.
The utility model is subsequent use with the liquid UV coating film-forming of going ahead of the rest, and to avoid space-pollution, malfunction or the like bad order increases yield.Solid face is coated with when using, and working environment requires lower, reduces investment outlay; Production technology is simple, cost is low and product surface is attractive in appearance beautiful, and cooked mode processing that can hot transfer printing can be processed on plastics, metal, glass, bamboo wood, pottery, the stone material.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
For further understanding characteristic, technological means and the specific purposes that reached, the function of the utility model, the utility model is described in further detail below in conjunction with the accompanying drawing and the specific embodiment.
Dependency structure mainly comprises with lower component (or device) among the figure: plastic sheeting 1, UV face are coated with rete 2, PUR 3.
See also shown in Figure 1ly, a kind of pellicular front of the utility model is coated with, and comprises plastic sheeting 1, introduces one deck UV face on the plastic sheeting 1 and is coated with rete 2, is coated with at the UV face and introduces one deck PUR 3 on the rete 2.Plastic sheeting 1 thickness is 0.01~1mm, and it is 0.01~1mm that the UV face is coated with rete 2 thickness, and PUR 3 thickness are 0.01~1mm.During use, PUR 3 applying workpieces remove plastic sheeting 1, and the UV face is coated with rete 2 and exposes surface of the work.The UV face is coated with rete 2 and is ultraviolet-curing paint or first heat cure two UV curing photocureable coating of solidifying of UV again; Plastic sheeting 1 adopts all types of light-passing plastics such as PET, PC, PVC, PEVA, EVA and OPP, and PUR 3 is become to be grouped into by basic resin, tackifier, viscosity modifier and antioxidant etc.
The utility model comprise coating UV face be coated with mode, plastic sheeting (PET, PC, PVC, PEVA, EVA, and all types of light-passing plastics such as OPP), occupation mode, can release UV coating or first heat cure UV technical essentials such as two UV curing photocureable coating of solidifying again.
Difference between the utility model and the existing scheme on performance:
During use, PUR 3 applying workpieces, after pressurization, the heating, PUR 3 sticks on surface of the work, and remove plastic sheeting 1 this moment, is that UV finishing coat 2 exposes surface of the work.
The process that making the utility model pellicular front is coated with is following:
1., plastic sheeting 1 arrangement: plastic sheeting 1 (PET, PC, PVC, PEVA, EVA, and all types of light-passing plastics such as OPP) arrangement is subsequent use;
2., the UV face is coated with coating: can be coated with and evenly be coated on the plastic sheeting 1 from film UV face with coating method;
3., solidify: but the plastic sheeting 1 that is coated with of coating UV face carries out heat cure or UV photocuring, makes its UV face that forms a tool intensity be coated with rete 2;
4., coating PUR: be coated with on the rete 2 at the UV face that has solidified, coating one deck hot melt adhesive layer is finished product thereby accomplish.
The utility model adopts technology such as hot transfer printing, face are coated with, UV coating, relates to treatment process such as incrustation, surface peening.
The above embodiment has only expressed the part embodiment of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with accompanying claims.
