The utility model can make flexo resin plate cost significantly reduce, performance is more stable, well-known current domestic resin plate is not high in whole flexo industry utilization rate, low-cost hand engraving flexographic is then selected by larger a part of flexo enterprise, the printing effect of flexographic is poor, resistance to print is low, service life is short, production efficiency is low, it is suitable with manual flexographic cost that the utility model can make the cost of resin plate be reduced to, superseded manual flexographic can be accelerated like this, all flexo enterprises are allowed to use inexpensive resin plate, improve the quality of package printed matter, make domestic printing enterprise more competitive.
Accompanying drawing explanation
Fig. 1 shows the structural representation of the flexo resin plate of the first embodiment in the utility model;
Fig. 2 shows the structural representation of the flexo resin plate of the second embodiment in the utility model;
Detailed description of the invention
For fully understanding the object of the utility model, feature and effect, by following concrete embodiment, utility model is elaborated, but utility model is not restricted to this.
Embodiment one
The utility model provides a kind of flexo resin plate, as shown in Figure 1, flexo resin plate of the present utility model comprises from top to bottom successively: base material 1, elasticity ground 2, tack coat 3, hydroelasticity photosensitive resin 4, wherein, base material 1 material selects the plastic sheetings such as polyester, polypropylene, three vinegar three fat or other Nature comparison to stablize on-deformable clear sheet, base material 1 thickness is 0.05-0.2mm, owing to adding the structure of elasticity ground 2 in the utility model, therefore, flexible resin plates of the present utility model can be selected without the need to matrix structure.Elasticity ground 2 selects SH to be the material of 30-70, such as PVC, EVA, silica gel, rubber, this kind of material is cheap relative to photosensitive resin to be easy to get, the thickness of elasticity ground 2 is a half thickness of flexo resin plate, may further be 0.8-2.8mm, elasticity ground 2 plays resiliency supported effect.Tack coat 3 is a kind of UV adhesives, has excellent adhesive force to base material 2, can make it into be under ultraviolet light simultaneously integrated with hydroelasticity photosensitive resin 4 cross-linking reaction.
The preparation method of a kind of flexible resin plates of the present embodiment is: first base material 1 can be compounded in below elasticity ground 2 by the mode such as glue or ultra-sonic welded, form supporting construction, secondly on the surface of elasticity ground 2, tack coat 3 is set by coating or silk-screen mode, after layer 3 to be bonded drying, the hydroelasticity photosensitive resin 4 of desired thickness is set further on tack coat 3, finally lay the film (not shown) needed for plate-making on hydroelasticity photosensitive resin 4 surface, the flexo resin plate printed can be obtained through overexposure, development, post processing.
Elastic bottom equipment structure is not had in existing flexo resin plate, it passes through double-sided exposure, make bottom photosensitive resin, to form resin bottom, but bottom only plays elasticity support effect (the relief image subparticipation printing only having face exposure to be formed) in printing process, because elastomer UV photosensitive resin price is high, and the consumption of half just plays the effect of elasticity support, so, the cost that in prior art prepared by flexible resin plates is high, is unfavorable for extensive use.
The utility model is by increasing elastic bottom equipment structure, reduce the consumption of photosensitive resin on the one hand, reduce flexo resin plate cost high, on the other hand, simplify the preparation technology of flexo resin plate, reduce exposure frequency, like this can cost-saving and plate-making time without double-sided exposure, can the making resin plate of fast and stable more.
Embodiment two
The utility model provides a kind of flexo resin plate, and as shown in Figure 2, flexo resin plate of the present utility model comprises from top to bottom successively: base material 1, elasticity ground 2, tack coat 3, solid, and photosensitive resin 4 puts adhesion coating 5, protective layer 6.
Wherein, base material 1 material selects the plastic sheetings such as polyester, polypropylene, three vinegar three fat or other Nature comparison to stablize on-deformable clear sheet, base material 1 thickness is 0.05-0.2mm, owing to adding the structure of elasticity ground 2 in the utility model, therefore, flexible resin plates of the present utility model can be selected without the need to matrix structure, further, because the utility model is without the need to double-sided exposure, therefore, the material of elasticity ground is no longer limited to transparent material, as long as elastic material.Elasticity ground 2 selects SH to be the material of 30-70, such as PVC, EVA, silica gel, rubber, this kind of material is cheap relative to photosensitive resin to be easy to get, the thickness of elasticity ground 2 is a half thickness of flexo resin plate, may further be 0.8-2.8mm, elasticity ground 2 plays resiliency supported effect.Tack coat 3 is a kind of UV adhesives, has excellent adhesive force to base material 2, can make it into be under ultraviolet light simultaneously integrated with hydroelasticity photosensitive resin 4 cross-linking reaction.
The preparation method of a kind of flexible resin plates of the present embodiment is: first base material 1 can be compounded in below elasticity ground 2 by the mode such as glue or ultra-sonic welded; form supporting construction; secondly on the surface of elasticity ground 2, tack coat 3 is set by coating or silk-screen mode; after layer 3 to be bonded drying; desired thickness extrusion solid elastic sensation photopolymer resin 4 is pressed further on tack coat 3; wherein; solid elastic photosensitive resin 4 is stirred by obtaining after hot mastication by batch mixing; adherent layer 5 and protective layer 6 is spread again on solid elastic photosensitive resin 4
Finally throw off protective layer during plate-making, spread the film (not shown) of plate-making, then expose, development, post processing finally obtains flexo resin plate.
Elastic bottom equipment structure is not had in existing flexo resin plate, it passes through double-sided exposure, make bottom photosensitive resin, to form resin bottom, but bottom only plays elasticity support effect (the relief image subparticipation printing only having face exposure to be formed) in printing process, because elastomer UV photosensitive resin price is high, and the consumption of half just plays the effect of elasticity support, so, the cost that in prior art prepared by flexible resin plates is high, is unfavorable for extensive use.
The utility model is by increasing elastic bottom equipment structure, reduce the consumption of photosensitive resin on the one hand, reduce flexo resin plate cost high, on the other hand, simplify the preparation technology of flexo resin plate, reduce exposure frequency, like this can cost-saving and plate-making time without double-sided exposure, can the making resin plate of fast and stable more.
