Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2, the invention provides a composite printing paper film 10 with environment-friendly sticking transfer direct printing paper, comprising:
1, compounding base paper;
the printing film layer 2 is arranged on the composite base paper 1, one surface of the printing film layer 2 is connected with the composite base paper 1 and is a non-printing surface 2A;
the other side of the printing film layer 2 is used for printing patterns and is a printing surface 2B.
The composite printing paper film is a composite material consisting of at least one composite base paper 1 with water transfer performance and at least one printing film layer 2 convenient for applique. After the composite material is soaked in water, the printing film layer 2 can be separated from the composite base paper 1.
The invention changes the printing mode of the prior water transfer printing paper printing layer, and directly prints the pattern on the printing paper film 2 instead of the water transfer printing base paper. The printing paper film 2B is used as a printing surface, and has extremely high smoothness and extremely low roughness, and the plastic film has excellent dimensional stability and is not easy to absorb moisture and deform like paper, so that the printing exquisite degree of the invention is far superior to that of the traditional stained paper. Moreover, when the printing paper film is used for producing the stained paper, the printing film layer serves as a printing and transferring base material, and a traditional cover glue layer is not needed, so that the solvent emission in the printing process can be greatly reduced, the energy is saved, and the emission is reduced. In addition, compared with the stained paper manufactured by adopting a water transfer printing base paper and cover glue mode in the prior art, the new material and the new structure stained paper simultaneously have stronger cost competitive advantages, and the cost is reduced by more than 40%.
When the stained paper with the novel structure is applied to subsequent applique, the method of traditional water transfer applique can be adopted, the stained paper is soaked in water and then the printed film layer with the printed layer is separated, and simultaneously, the printed surface of the printed film layer is pasted on the surface of an object. After the decal is dried or baked, the transferred substrate film can be easily peeled off from the print layer intact without damaging the print pattern. Therefore, how to realize that the printed film can be easily peeled off completely without damaging the printed pattern is a technical difficulty realized by the present invention.
For this reason, the printed film layer of the printed paper film needs to be formulated and applied with proper corona treatment so that it has both good printability and a lower release force from the printed layer than from the printed layer and the surface of the article, so that the printed film layer can be easily and completely peeled off. However, if the release force is too low, the printed layer may be separated from the film too early before or during the pasting process, which may cause the transfer failure of the printed layer, and the release force is too low, the surface of the printed paper film has no good printability, the pattern is difficult to be printed on the printed paper film completely and delicately, and the printed paper film cannot be used normally.
In order to overcome the two factors of the stripping property and the printing property of the printing paper film which are mutually restricted, the surface tension of the printing surface 2B of the printing paper film is controlled to be 32-38 dynes. When the surface tension is more than 32 dyne, the printing surface of the printed paper film has good printability. But the surface tension of the surface should be less than 38 dynes in order for the decal layer to be removed after the decal without destroying the printed image. If the surface tension of the printing surface 2B of the printing paper film is less than 32 dynes, the printing surface of the printing paper film does not have good printability and is difficult to print; if the surface tension of the printing surface 2B of the printing paper film is greater than 38 dynes, the printing film layer is difficult to be peeled off from the surface of the printing layer.
Preferably, the surface tension of the printing surface 2B of the printing paper film is 32-37 dyne. More preferably, the surface tension of the printing surface 2B of the printing paper film is 32-36 dyne.
In the aspect of preparing the printed paper film, the printed paper film is prepared by a plastic resin extrusion and film spraying process.
The lamination is a process method for plasticizing and melting plastic resin by adopting a plastic extruder, and then enabling the resin in a flowing state to be sprayed on a base material through a narrow slit die orifice of a T-shaped die head to form a composite material structure.
The surface tension of the printing paper film can reach 32-38 dynes by selecting a laminating raw material and a compounding auxiliary agent and carrying out proper corona treatment on the printing surface.
Specifically, the printing film layer is made of one or more of polyethylene, polypropylene, polyvinyl chloride, POE, ethylene-vinyl acetate copolymer, polyvinyl alcohol, polyurethane, ABS and ethylene-propylene-diene copolymer resin. The surface tension of the resin is adjustable within 32-38 dynes, and the requirements of the invention can be met. The raw material of the printing film layer can also comprise an auxiliary agent to be matched with the resin raw material for use. The auxiliary agent is one or more of an anti-adhesion agent, a slipping agent and an organic silicon surface tension adjusting auxiliary agent.
As a preferable raw material formula of the invention, the raw material formula of the printing film layer is any one of the following materials:
(1) polyethylene resin with tensile strength of 4-12 MPa;
(2) ethylene-vinyl acetate copolymer resin with the tensile strength of 4-12MPa, an anti-sticking agent and a slipping agent, wherein the addition amount of the anti-sticking agent and the slipping agent is 0.1-10% of that of the ethylene-vinyl acetate copolymer resin;
(3) the mixed resin of polyethylene and POE with the tensile strength of 4-12MPa, wherein the use ratio of the POE is 20-30%, and the use ratio of the polyethylene is 70-80%;
(4) the mixed resin of ethylene-propylene copolymer resin with tensile strength of 4-12MPa and POE, wherein the use ratio of POE is 20-30%, and the use ratio of ethylene-propylene copolymer resin is 70-80%.
(5) The ethylene-propylene copolymer resin with the tensile strength of 4-12MPa, wherein the ethylene content is 5-10%.
The surface tension of the printing surface 2B of the printing paper film can be 32-38 dynes, and the printing film layer has low tensile strength and good applique operation performance.
In order to meet the requirement that a printed film layer transferred from the decal paper in the decal process has better decal operation performance and a thin film material of the printed film layer needs to have lower tensile strength, the tensile strength of the raw material of the printed film layer is set to be 4-12MPa, and the method is one of the key technical difficulties for realizing the product. The common plastic resin has higher tensile strength, and the conventional plastic resin is selected, so that the printed film layer cannot have good stretchability, has poor applique operation performance, and cannot meet the requirements of containers in various shapes. The thickness of the printing film layer is set to be 8-40 microns. The printed film layer with the tensile strength and the thickness has the advantages of convenient applique operation and strong practicability.
Preferably, the tensile strength of the printed film layer is 5-10MPa, and the thickness of the printed film layer is 10-30 microns. More preferably, the tensile strength of the printed film layer is 7-9MPa, and the thickness of the printed film layer is 15-25 microns.
In order to make the surface tension of the printing surface of the printing paper film reach 32-38 dynes, the invention can also be adjusted by carrying out corona treatment on the printing surface of the printing paper film.
It should be noted that the surface tension of the printing surface of the printed paper film can reach 32-38 dynes by other technical means, and the embodiment of the invention is not limited to the illustrated example.

Specifically, the bottom layer 11 is formed by coating a first coating material, the first coating material is a coating material prepared from kaolin/calcium carbonate, synthetic latex and an auxiliary agent, and the coating weight of the bottom layer 11 is 10-20g/m2The function of the coating is to form a relatively smooth surface on the surface of the base paper by coating.
The core layer 12 is formed by coating a second coating material, the second coating material is a modified starch water boiling solution or a solution prepared by water boiling modified starch with water-soluble raw materials, and the coating weight of the core layer is 3-7g/m2Its function is to form a smooth coating that absorbs water rapidly.
The surface layer 13 is formed by coating a third coating material which is a modified starch boiled solution, and the coating weight of the surface layer is 2-5g/m2Its function is to form a fast water-soluble coating.
The composite base paper of the invention is printed after being compounded with the printing film layer, so that the composite base paper can be thinner than normal water transfer printing paper. The gram weight of normal water transfer printing paper is generally 135-190 g/m2The gram weight of the composite base paper is 40-130 g/m2。
