Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention does not use ordinary adhesives, organic solvents, etc.
This invention relates to a method 1C for laminating a plastic film on the surface of printing paper or the like by a simple means.

<Prior Art> As is well known, printed matter such as paper cartons, publications, cards, Bosk-1 and other paper products (hereinafter referred to as "printed matter, etc.") K is used to protect the printed surface, provide water resistance, #oil-based properties, etc. Addition and even gloss. In many cases, a plastic film is laminated on the surface for the purpose of beautification, etc., and this type of processing is called ``print laminate'' or ``print laminate J'' in the entire industry.

Conventionally, in the coating section of a laminating machine, adhesive dissolved in an organic solvent is applied to a glass film in the coating section of a laminating machine, and after the organic solvent is scattered through a drying process, the adhesive-coated surface of the glass film and This is done by thermocompression bonding with printing paper, etc.

However, the method using organic solvents has problems in terms of work safety such as the risk of fire, health management of workers, and environmental protection such as the generation of odors and air pollution. However, there was a strong demand for a laminating method that did not require the use of organic solvents. In addition, in the conventional method of glazing, when the adhesive is heated and laminated between a mirror-finished heated metal roll and a pressure roll, the adhesive is softened by heat, and as a result, the heated metal roll smoothes the surface of the glass film, making it glossy. This takes advantage of the fact that the color comes out, and naturally the higher the temperature, the better the gloss. However, with the conventional method, it is impossible to completely remove the organic solvent contained in the adhesive applied to the plastic film, and some residual solvent may foam due to #fC heat during natural pressure bonding. However, in order to suppress foaming as much as possible, it is necessary to heat and press it at a low temperature, but this will result in a lack of gloss, so there will be no foaming and the gloss will remain, which is both satisfactory. It was difficult to do so. In other words, conventional products are unsatisfactory, with some foaming and lack of gloss.
This was a serious drawback in terms of product quality.

In view of the technical background of VC, the present inventors developed a new print laminating method and first published the patent application No. 20876
The application was filed as No. 0, but the gist of this is ``The heat-sensitive adhesive resin layer of a composite polypropylene film on which a heat-sensitive adhesive resin layer is laminated is brought together with the printed surface of printing paper, etc., and the metal-- This method solves the conventional problem of foaming during thermocompression bonding, but further study was required in terms of gloss. In other words, instantaneous thermocompression bonding is inevitably insufficient for achieving gloss, and although it is theoretically possible to apply gloss using a press, there are problems such as complicating the process and reducing efficiency. Unable to put it into practical use, we investigated a new solution that would allow glazing to be carried out in succession with this refined thermocompression bonding process, and filed an application as Japanese Patent Application No. 1984-4N91. One method of the gist is [when laminating a print lamination film consisting of at least two layers, a base film layer and a heat-sensitive adhesive resin layer, with printing paper, etc. A device is used in which an endless metal belt with a mirror-finished surface is stretched around the outer periphery of a heated metal roll and an auxiliary roll, and a pressure roll is provided opposite to the heating metal roll via the endless metal belt. , between the metal endless belt and the pressure roll,
The printing paper, etc. is arranged on the pressure roll side to the base film layer all-metal endless belt side, and the print lamination film and the printing paper, etc. are fed and heat-compression laminated, and then the laminated film is laminated. This is a method for obtaining a glazed and printed laminated product by transporting the object in close contact with the metal endless belt, and this method has almost solved the conventional problems.

<Problems to be Solved by the Invention> However, in the above method, an endless metal belt is located between a heated metal roll and a pressure roll that face each other. Since the material film layer is placed on the belt side and the printing paper etc. is placed on the pressure roll side, the contact between the endless belt and the film surface is inevitably weak, which causes problems such as not being able to obtain better gloss. there were.

Means to solve the problem〉 (・Method I) Misfire F! As shown in Figure 1, factor 7, A is a print lamination film fi+ consisting of at least two layers, a base film layer (2) and a heat-sensitive adhesive resin layer) 31, and a printing paper etc. (4).
), the film fi+ is placed on the heating roll (7) side and the printing paper, etc. (4) is placed on the pressing roll +81 side between the heating roll tL/(71 and the pressure roll (81), which are arranged opposite to each other. Then, the heating roll +71 (!: the heating roll +71) is placed between the heating roll +71 and the endless circulation member f101 provided in the K-surface contact shape 1c, and the thermocompression bonding is performed to obtain the laminate body (6). body (6)
The film surface is subjected to a VC polishing process.

(Means ■) As shown in the sixth factor, the means (heating rolls of IJ placed opposite to each other) and the pressure roll (the heating roll α of IgI)
A heating metal roll +191 is provided separately from η, and an endless circulation member (lOlt- is provided in the surface contact with this roll (I91VC), and between the control and endless circulation member (lO), there is a laminate bonded by thermocompression. The body te (@ is run, and the film surface Il+ in No. 10 is polished. Also, No. 8
The figure is different from Figure 6, and is made of laminated tar printing paper, etc.
4) It was run so that the side was in contact with the heated metal roll: 1 ru 0 <Function> In Figure 1 and the WSZ diagram, one sheet is placed from the paper feed section (not shown) with the printed surface facing upwards. As shown in FIGS. 2 and 5, printing paper, etc. (41 (sheets) are fed toward the press-bonding section (!1) with their opposing ends stacked one on top of the other (!1). T1 film +l+ is supplied to the pressure bonding part +Illic in such a way that its heat-sensitive adhesive resin layer (31) is aligned with the printed surface of the sheet (41). When it reaches the temperature, the laminate body (6) is bonded by heat and pressure between the heating roll (71) and the pressure roll (81).
However, the laminate body (6)' continues to run in surface contact with the heating roll 71, and during this surface contact running, the endless circulation member (1) disposed in surface contact with the heating roll (71)
By applying pressure from the 41 side, each component of the laminate (61°) is more strongly integrated and the film surface is polished.

Figure 6, W! Figure I8 is the same as in Figures 1 and 17, and the surface contact with the endless circulation member (101) is a heating metal roll, and this roll (IgI is separate from the former heating roll (7)). It is set up and heated = - le (7)
(And by two-stage heating of heating metal roll 09,
The laminate body (61) can be more smoothly integrated with each component and polished.

Example The present invention will be explained in detail below.

The film for print lamination according to the present invention (1) refers to a lamination B film having at least two layers: the base film layer (2) and the FIAig+adhesive resin layer +31, and the base film layer (2). Examples include stretched or unstretched films made of polyolefins such as polypropylene, polyesters, polyamides, and other thermoplastic polymers, which have a higher melting point than the polymer forming the heat-sensitive adhesive resin layer (3). 1. Preferably, the biaxially stretched film IJ propylene film/Af can be exemplified.In this case, the above-mentioned biaxially stretched film 11 is melted, and the residue extracted with butane is 90%. The above polypropylene homopolymers, probiracy α-olefin copolymers with an α-olefin content of 5 mol% or less, and propylene homopolymers blended such that the 6 or total propylene content is 95 mol% or more. It is preferable to use a mixture of propylene-α-olefin copolymer, and it is also preferable to use the above-mentioned polypropylene resin mixed with film waste generated during the production of the film according to the present invention. Thickness of base film layer 12I There is no particular limit to the thickness, but one with a thickness of about 10 to 20 μm is preferred.
Furthermore, base film layers that have been colored or surface-treated, or have lubricants, anti-blocking agents, stabilizers, ultraviolet absorbers, antistatic agents, etc. added may also be used as required.

In addition, the heat-sensitive adhesive resin layer (3) laminated on the above base film layer (2I) is not particularly limited as long as it is a solvent-free material with a lower melting point than the base film, but it is preferable to use ethylene. Examples include polymers as main components, such as polyethylene or copolymers containing at least 70% by weight of ethylene, or mixtures of polymers having a total ethylene content of 70% by weight or more. There are no special restrictions on the monomer copolymerized with ethylene at this time.
It is acceptable if it is a monomer that can copolymerize with ethylene. The desired monomers include, for example, propylene, butene-1, he-4f-1, vinyl acetate, ethyl acrylate, and acrylic acid. Furthermore, those modified by copolymerization followed by hydrolysis or crosslinking with metal ions, and those modified by graft polymerization with anhydrous macerate, leic acid, etc. can also be used. However, if the total ethylene content is less than 70% by weight,
It is difficult to return the film waste generated in the film manufacturing process or the slitting process to the base film layer, for example, the above-mentioned polyglobylene layer, and reuse it, which is not preferable from the viewpoint of resource saving.

If you dare to return these,
This is because transparency, flexibility, dimensional stability, etc. may be significantly deteriorated, resulting in a polypropynone film that cannot be put to practical use. Therefore, the total ethylene content is at least 70 wt., or more specifically, 85 wt.:l.
This can be exemplified as a desirable range for noise. Of course, if the above-mentioned returns are not taken into consideration, there is no point in using the product even if it falls outside of this range. In addition to the above-mentioned nine ethylene-based polymers, propylene-based polymers, such as polypropylene, a globylene-ethylene copolymer containing a large amount of propylene (e.g., 55 mol% or more) 'ppropylene-1 A -7 tenene copolymer or the like may be added. These propylene are the main 1j! It is convenient because it can improve the lubricity of the product by adding a polymer containing it. In addition, lubricants, anti-blocking agents, stabilizers, colorants, ultraviolet absorbers, antistatic agents, other thermoplastic polymers, etc. are added to the heat-sensitive adhesive resin layer to meet various requirements and quality such as transparency and thermal adhesiveness. It goes without saying that the present invention can also be used in cases where the additives are added within a range that does not impair the properties.

Any known method may be used to produce the print lamination film 111, which is a laminated film consisting of a base film layer (21) and a heat-sensitive adhesive resin layer (31) according to the present invention. Heat-sensitive adhesive The thickness of the adhesive resin layer (3) may be appropriately selected depending on the smoothness of the surface of the printing paper, the required adhesive strength, etc., but it is usually preferably 1 to 5 μm. It does not preclude the use of a layer with a thickness of SP or more. However, this results in unnecessary surface layer thickness.

Although there are no particular restrictions on the heat-sensitive adhesive resin layer (3), it is preferable that the heat-sensitive adhesive resin layer (3) be subjected to a surface treatment in order to impart thermal adhesion to the printing paper, etc. (4). General methods such as chemical treatment, flame treatment, and corona discharge treatment are examples, but corona discharge treatment is particularly effective, and among them, corona discharge treatment is performed in a nitrogen atmosphere with an oxygen concentration of 20.9%. This is even more effective. At this time, the residual oxygen concentration in the nitrogen atmosphere is assumed to be the oxygen concentration in the air.
The effect is recognized at less than 20.9 volume%, which is less than 0.9 volume duck, and the lower the residual oxygen concentration, the greater the effect.
Preferably it is 5 volumes or less. Corona discharge treatment strength, film temperature during treatment, etc. may be appropriately selected depending on the desired adhesive strength, but are usually 20 to +OOOW.

min/lri, room temperature to about 90°C. Any known method may be used to create a nitrogen atmosphere, such as enclosing the entire corona discharge treatment mechanism in a box and replacing the air inside with nitrogen gas, or spraying nitrogen gas into the corona discharge section through a slit or the like. can be exemplified. Further, there is no @VC restriction whether the surface treatment applied to the heat-sensitive adhesive resin layer (3) is carried out before lamination or after the S layer is formed. ′! In addition, the film for print lamination according to the present invention (1
) may be formed by laminating a film layer made of an appropriate material on the base film layer (2), or by laminating an appropriate thermoplastic film layer between the base film layer (2) and the heat-sensitive adhesive resin layer (3). Of course, a three-layer structure or a three-layer structure or more may be formed by interposing a polymer layer, for example, an intermediate layer made of a propylene-based copolymer containing propylene as a main component.

Next, the method of the present invention will be explained with reference to the drawings. FIG. 1 is a side view showing the main parts of a preferred apparatus used in the method of the first invention. Printed paper, etc. (41
