Description

PP (polypropylene) back adhesive for inkjet advertisement printing

Technical Field

The utility model belongs to the technical field of the advertisement apparatus, especially, relate to a PP gum is used in printing of air brushing advertisement.

Background

The PP back glue of the advertisement consumable material commonly used in the current market uses PP synthetic paper as a substrate, the used method is that a layer of cold mounting film is mounted after a printed picture is dried, then PET release paper on the back is torn off, so that non-setting adhesive on the back of the PP substrate is completely attached to a KT plate, and a scraper blade is used for scraping and extruding bubbles. Chinese patent No. CN201320195937.X, named as adhesive-backed film, discloses an adhesive-backed film with a multilayer structure, which comprises an ink absorption layer, a substrate, an adhesive sticker, a silicone oil layer and PET, wherein the substrate is sequentially adhered with meshes. In the use process of the back glue film, gaps exist among fibers of the base material or the coated paper with meshes, so that a loose and porous structure is formed, and the air permeability of the back glue film can absorb volatilized residual solvents, so that the generation of bubbles is greatly reduced. However, when such a back adhesive is used, when a printed picture is directly attached to another picture, the printed picture is affected by the bottom picture due to the light transmittance, so that the use effect is poor. Simultaneously, the gum is when the air brushing is printed, because the smoothness of gum can make the gum paper advance skid to influence the printing effect of gum. Above-mentioned patent is at the air brushing blotting in-process, and the ink has relatively poor mobility to thickness is inconsistent when making the air brushing, influences the air brushing blotting effect.

Disclosure of Invention

An object of the utility model is to solve above the technical problem provide an improve opacity of gum, make the picture can directly paste and cover on other pictures, and do not receive the bottom picture to influence, the paper feed skidded when preventing that the material from printing, the air brushing advertisement that improves the air brushing ink absorption effect is printed and is used PP gum, its technical scheme as follows:

spray painting advertisement is printed and is used PP gum, including blotting layer, PP synthetic paper layer, silicon oil layer and PET layer, its characterized in that, PP synthetic paper layer and blotting layer between be provided with white light shield layer, PP synthetic paper layer and silicon oil layer between be provided with grey light shield layer and acrylic acid pressure sensitive adhesive layer, the back on PET layer be provided with dull polish skid resistant course. White light shield layer, grey light shield layer set up respectively in PP synthetic paper layer's two faces on the front and back, can the omnidirectional improvement product light-proofness, guarantee 100% opacity, make the picture can directly paste and cover on other pictures, and do not receive the bottom picture influence. The frosted anti-slip layer can prevent paper feeding slip during material printing, and printing effect is improved.

Preferably, the gray shading layer is convex, two ends of the gray shading layer are arranged on the back of the PP synthetic paper layer, and the convex part of the gray shading layer is positioned in the PP synthetic paper layer. The back adhesive also needs to consider the problem of thickness when in use, and if the number of layers forming the back adhesive is too large, the thickness is too thick, the use of the product is influenced, and the cost is increased. The gray shading layer is convex, so that the thickness of the whole product can be reduced to a great extent, the thickness of the gray shading layer can not be reduced, and the shading performance of the product can not be reduced.

The frosted anti-slip layer is provided with the rhombic bulges, so that the surface of the PET film is rough, and paper feeding and slipping during printing are prevented. The frosted anti-skid layer is produced by coating an anilox roller, the anilox roller with rhombic concave grains is used for coating double-component polyurethane water-based frosted resin, after the coating is dried, a rhombic convex frosted layer is formed on the surface of a PET (polyethylene terephthalate) film, and the frosted anti-skid layer has the performances of water resistance and scratch resistance due to the used double-component coating.

Preferably, a light-shielding adhesion promoting layer is arranged between the PP synthetic paper layer and the gray shading layer. The light-shielding adhesion promoting layer can improve the adhesion between the PP synthetic paper layer and the gray shading layer, and prevent the falling problem caused by poor adhesion.

The light-shielding adhesion promoting layer may be a white light-shielding layer.

The utility model has the advantages that: the opacity of the back adhesive is improved, so that the picture can be directly pasted on other pictures without being influenced by the bottom picture, the paper feeding slip during the printing of the material is prevented, and the ink absorption effect of the spray painting is improved.

Detailed Description

The following embodiments are specifically described with reference to fig. 1 to 3:

as shown in fig. 1, the PP back adhesive for inkjet advertisement printing comprises an ink absorption layer 1, a PP synthetic paper layer 2, a silicone oil layer 3 and a PET layer 4, wherein a white shading layer 5 is arranged between the PP synthetic paper layer and the ink absorption layer, and a frosted anti-slip layer 8 is arranged on the back of the PET layer; and an acrylic acid pressure-sensitive adhesive layer 7 is arranged between the PP synthetic paper layer and the silicon oil layer.

The white shading layer mainly comprises the following components: titanium dioxide, polyacrylate and water dispersible polyisocyanate. The light shading agent has the effects of shading light and improving the adhesive force, promoting the adhesive force between the white light shading layer and the PP synthetic paper layer and preventing falling.

The frosted anti-skid layer is provided with diamond-shaped bulges.
