Description
Technical Field
The utility model relates to a print membrane technical field, more specifically the utility model relates to a no backing paper environmental protection self-adhesion waterborne shinny printing membrane.
Background
The back glue printing film taking PVC as the spray painting base material has the characteristics of softness, good fitness and high ductility, is widely used for advertisement display of indoor and outdoor products, and is more suitable for sticking and displaying of cambered surfaces or concave-convex panels compared with spray painting advertisement materials taking PP and PET as base materials. PVC printing advertisement consumables on the market mainly comprise vehicle body pastes and water-white, wherein the vehicle body pastes are suitable for weak solvent and strong solvent ink printing, and mainly comprise laminated PVC films, pressure-sensitive adhesives and release paper structures, the PVC thickness is 70-100 um, the pressure-sensitive adhesive thickness is 15-30 um, the gram weight of the release paper is 120 g/square meter and 140 g/square meter; the water white is formed by coating a water-based PVA ink-absorbing coating on the surface layer of the automobile body paste, is suitable for water-based dye printing ink, and has three types, namely matte, silky and smooth surfaces.
However, weak solvent and strong solvent inks used for vehicle body stickers contain organic solvents such as alcohols, esters, ethers, benzenes and the like, and the solvents remaining in the film during printing and after drying can affect human health, and indoor use has limitations. Compared with vehicle sticker products, water white products are more environment-friendly in inkjet printing, but can only be suitable for water-based dye ink printing, and cannot meet various requirements of customers. Meanwhile, the pressure-sensitive adhesive used in the adhesive layer must be matched with release paper for coating and gluing and providing a release effect, and the release paper is not needed to be torn off when being used by a terminal customer, so that the waste of resources and the increase of garbage amount can be caused.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a backing paper-free environment-friendly self-adhesive water-based white and bright printing film which has simple structure, is suitable for water-based machine spray painting and is compatible with dye and pigment ink; and pressure-sensitive adhesive is not contained, release paper is not needed, and material cost is saved.
The utility model provides a technical scheme that its technical problem adopted is: the improvement of a backing-paper-free environment-friendly self-adhesive water-based white and bright printing film is as follows: comprises a white and bright compatible ink absorption layer, a bottom coating, a PVC white film and a self-adhesive layer;
the PVC white film is a substrate layer, the PVC white film is provided with a smooth surface and a dummy surface, the smooth surface of the PVC white film is jointed with the bottom coating, and the dummy surface of the PVC white film is jointed with the self-adhesive layer;
the white and bright compatible ink absorption layer is a high-gloss nano coating, the white and bright compatible ink absorption layer is attached to the bottom coating, and the white and bright compatible ink absorption layer and the PVC white film are fixed through the bottom coating.
In the structure, the thickness of the PVC white film is 70-150 um.
In the above structure, the density of the PVC white film is 1.3-2g/cm3。
In the above structure, the primer layer is a water-based two-component cured primer layer.
In the structure, the self-adhesive layer is starch glue adhesive glue, and the self-adhesive layer contains one or a combination of more of starch, PVA and PMC.
In the above structure, the self-adhesive layer is any one of transparent, milky white and black.
The utility model has the advantages that: the coating is compatible with dye and pigment water-based spray-painting ink, so that more types of spray-painting machines are selected for advertisement makers; meanwhile, the ink absorbing layer is pressure-resistant and not dull, and has higher grade compared with the common water white; a special self-adhesive layer is coated on the PVC white film matt surface layer, and release paper is not needed, so that the material cost is greatly saved, the garbage discharge amount is reduced, and the PVC white film matt surface layer is environment-friendly and practical.
