Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing gold 8 metallized paper using an extrusion lamination method.

Conventionally, gold (g! It has the disadvantage of inhibiting X-coating, and also has the disadvantage of poor surface smoothness and low gloss.In particular, coated paper, which has a 0-foot foot to make the surface smooth in all directions and has a glossy appearance, If you use gold V art paper, n: V vapor-deposited gold V, vapor-deposited paper is also manufactured, but there is nothing that can be used for surface smoothness and gloss i1 !+, , 1 j,, mellow t. In addition, the problem of outgassing during vacuum deposition could not be solved, resulting in poor productivity.
The present invention not only completely eliminates the drawbacks of conventional methods, but also provides a method for efficiently producing metal-deposited paper with excellent moisture resistance.

The wtr+Yk of the present invention will be explained below based on the attached drawings.

This invention utilizes the J-extrusion laminating method, and the nip roll + 211 tl of the laminator (1) has a paper strip (4) on one side and a vapor-deposited Igiri (3) from which at least at least the gold i1 vapor-deposited layer can be removed from the other side. The metal vapor-deposited base material (3) is fed into a continuous tube with the vapor-deposited surface facing inward. It is preferable to treat the surface of the metal-deposited substrate (3) with a care anchor coat before feeding it between the honey rolls. Yes. Further, from the extrusion guide (51), a molten resin (61) is applied, and the same resin (6) is fully compressed by pressing with the nip roll (2), and the above-mentioned art material (3) (41) is laminated Fj!j:. Then, in the laminated art materials, the metal vapor deposited layer of the metal vapor deposited base material adheres more strongly to the paper material side than to the same substrate side, so that at the next number of rolls, both! When the paper material (4) is rolled up separately, a metallized paper (7) is formed with a metallized layer formed on the surface of the paper material (4), and the metallized base material (3)
For those with metal vapor deposition layer, base film +71 N+
-The body is f, r. Furthermore, this base film is m
It can be used as a film for KJA A base plate 4.

By the way, the metal vapor deposition base material used in the present invention is
Basically, it is sufficient that the metal #1 on the base film is at least covered with #111 so that it can be peeled off to the layer laminated with the melted resin in the extrusion lamination method, and There is @俤 like .

For example, as shown in Figure 2, synthetic resin film (l()
Release A11 layer (gold vapor deposited layer flf on 91H)
As shown in FIG. 3, a top coat layer (11) is coated on a Ti7 resin film (8) through a first graining layer (9). This is an example in which a metal vapor deposited layer +1111 is applied to the l- layer.

Here, as the synthetic resin film, for example, films of polyester, polyethylene, bistyrene, biaxially oriented polypropylene, acrylic, etc. are suitable.As the J agent layer, cellulose acetate, nitrified cotton, acrylic wax, etc. are suitable. As the vacuum-deposited metal, biaxially oriented polypropylene combined with silicone resin K m M A1 is preferably used as a synthetic resin film suitable for the shape of the rod, such as aluminum. Paper material and I2 H20-81
0g7m' can be used, and non-woven fabrics and synthetic paper can also be used.

Next, an example of misfire 1114 will be described.

Example 1 In the extrusion lamination method, 84 g/m' thin paper was used as the material for one side to be fed between the nip rolls, and the other base material was a 25 μ thick polyester film with 0.0 g/m
7 g/m' acrylic-wax type release side was applied, and a metal vapor-deposited base material was used, which was vacuum-deposited with aluminum to a thickness of 400 mm.

The resin to be melted and suspended from the extrusion die is extruded into polyethylene at a melting temperature of 8111°C. The nip I:F was 8.5 υ, the winding distance was 80 m/min, and both base materials were laminated and bonded to each other with an inward width of 1'llf, and then wound separately.

The aluminum vacuum-deposited paper manufactured under these conditions has an extremely glossy surface compared to conventional, so-called direct-deposited products, and the paper does not suffer from bone-dry porcelain or heat during vapor deposition. Since the paper is not exposed to heat, there is no change in its dimensions, and it is free from curls caused by moisture absorption and heat. Not at all
A product with good Iv handling workability was obtained.Example 2 In the extrusion lamination method, one base material to be fed between nip rolls was bleached kraft paper of 70 g/m', and the other base material was 20μ thick. A top coat layer of 1.2 g/m' (Using urethane 7vk) was applied to biaxially oriented polypropylene (61 layers of silicone resin were added in parallel), and then aluminum was coated with a thickness of 150A. j1 Uses metal-deposited thread material. The top coat layer may be dyed as desired.

Note that the condition settings for 61+ are completely the same as in the first embodiment.
The aluminum vapor-deposited paper produced in this way was
It not only has the same characteristics as 1, but also has a top coat layer on its surface, which prevents the gloss and deterioration of the aluminum vapor-deposited surface. There is also an effect that can be reproduced.

By the way, the gold W obtained in Examples 1 and 2 of the present invention and the gloss + r of the metal-deposited paper of the prior art were measured by the experiment shown for the gloss and sound of conventional metal-deposited paper.

Experiment ASTM D-fi! -58T, all gloss measurements were performed using the fc2nW mirror damping measurement method. The gold-plated L vapor-deposited paper obtained in Example 1 and Example 2 above was used as the sample, and the 110 g/m' coated paper (all made by Nippon Kako Paper RA) was used as a comparison product. Aluminum was directly vacuum deposited.

A digital angular gloss meter UGV-4Qτ was used as the tester, and test conditions were 11: human incidence angle (eB: 20±05°, and the reference surface was a smooth black glass surface of 86.7 (20°)).

Table: Measurement Results As is clear from the measurement results in the above table, the glossiness of the products according to Example 1 and Example 2 of the present invention is much higher than that of the comparison product.

In addition to the above-mentioned embodiments, at least the metal vapor deposited layer is peeled off.
Mt was produced under the same conditions as in Example 1 using a biaxially oriented polypropylene film which had been subjected to vacuum evaporation of aluminum to which an appropriate amount of mold cutting had been added. Example 1
It had the same effect as the original one.

(The method of the present invention is an application of the conventionally known extrusion lamination method, and it can be used in existing extrusion lamination equipment warehouses and can be produced continuously, so it can be produced over a long period of time.) It is also ideal for manufacturing shakumono.

In addition, according to its nature, it can be applied to a wide range of paper sagging from 20 to 810 g/ba, so conventionally, it has been subjected to vacuum deposition. )If there was no vapor deposited layer on paperboard such as liner etc.
It became possible to increase f.

And 1, in the present invention, the paper material and the metal vapor deposited base material from which at least the metal vapor deposited layer can be peeled are bonded using a fluidized molten resin, so the art materials can be completely bonded. −) What is the current metallized paper obtained from this process? ! It is possible to completely bring the deposited layer into close contact with the paper phase surface without forming any bulges called Y-negative.

Moreover, the gold Pil vapor-deposited paper obtained by the method of the present invention has a high gloss and is easy to perform various types of printing by taking advantage of the texture of the paper.

However, although it depends on the type and quality of the paper used as the base material, genuine Osmanthus vapor-deposited paper is generally suitable for applications that require absolute strength, gas barrier properties, etc., and its use as packaging materials, etc. It is extremely wide.
