Description

[Detailed Description of the Invention] This invention 1± is a device in which a film material is attached to an electric signboard, a wall signboard, an exhibition billboard, and various other decorative panels. The present invention relates to the disclosure of an effective and novel method for manufacturing and reproducing spray plates.

Conventionally, this kind of display plate was made by pasting a decorative film such as acetate film or paper onto a glass board or an acrylic resin board using a pressure-sensitive adhesive or an emulsion adhesive. What is the position of the filter after pasting? ? In addition, the film cannot be changed without -IJ l, and air is sealed between the base 1 of the plate, etc. and the decorative film, and the 11 viewing state is Even if the film is good, it has the disadvantage of air bubbles that expand with time after 1-i temperature and makes it difficult to make the decorative film adhere to the eye.
-1 After the decorative film is attached, it is difficult to remove the air bubbles.

In addition, for electronic signboards, the display plate -1.
When air bubbles are formed, the air expands due to the temperature A, further deteriorating the properties of the base plate of the decorative film and causing wrinkles. This is to avoid the inconvenience of inducing 17 degrees of distortion from the eye of the film.

? ＞'/'' In the conventional case, when the decorative film of Ayatetov rum'S was glued with an emulsion-type adhesive, it became impossible to separate the eyes and the decorative film. This makes it impossible to use.

Next, pressure-sensitive adhesives harden over a long period of time, making it difficult to peel them off. Therefore, unless the adhesive is removed, it is difficult to use the decorative film as a display plate, and the finish is poor.

``The present invention was devised in view of the disadvantages in the prior art, and one of its 7 points is to solve the problem of air bubbles between an acrylic resin board and a decorative film such as an acetate film. It is designed to prevent bubbles from forming and, in the event that bubbles form, can be quickly removed.

In addition, the other main objectives of the present invention are:
・After applying the adhesive and before passing the film through a hot roll, the film can be freely adjusted in position, ensuring reliable display performance through in-cylinder operation. .

Historically, one of the other main objectives of the present invention is to enable i'+ utilization without damaging the acrylic resin plate and decorative film of used display plates, and to achieve economical This makes it possible to use +if function.

1. The present invention aims to achieve a suitable combination of various properties, and the gist of its structure is that the transparent glass is one side of a milky white acrylic resin plate.・f
Le, 11, jlj Decorative filter for paper etc. at 100℃
Through a combination of tyrene-resistant and acid-resistant hyaluronic acid F, which has been heat-melted at a temperature of ~150°C, the adhesive is cooled and solidified to form a laminate. Composition and +iiJ recording, Togo decorative fill j, from side to side, 8.
This invention consists of a structure in which the decorative film peels off from the surface of the acrylic resin board at high temperatures, and considerable changes are made to the effect of this structure.

1ζ, 74. , invention 1.゛(-To explain a typical embodiment whose details are shown in the drawings, (1) is an acrylic resin plate having 1- on the transparent side which serves as the eye, and the eye is 1-).
, 1 The ethylene-vinyl acetate copolymer formed into a film on the - side end of the horizontal fat plate (1) is used as -F body, and the angle is 100°.
E)t adjusted to have a melting point of C to 150°C
F-melt type adhesive film is attached, and the film 1, (2
) is melted using a heat roll Q) heated to 100°C to 150°C. Using this melted adhesive, the acrylic (1) and the acetate filter I( j. A decorative film such as paper (■) is joined, at this time the position of the film (■) is corrected, and the film (■) is naturally cooled and solidified (this is how a display plate is created).

The present invention has a unique structure, in particular, an acetate film on one side of a transparent or semi-transparent acrylic resin plate.
jlj1 paper etc! A Shikagawa filter J1 at 100°C to 15
through an ethylene-68 vinyl copolymer adhesive that is thermally melted at a temperature of 0°C.

a structure in which the adhesive is cooled and solidified to form a laminate; and a structure in which the decorative film 1 is peeled from the surface of the acrylic resin plate at any temperature from the surface of the laminated decorative film. By doing so, we have effectively corrected the deficiencies of the prior precedent mentioned above, and we hope to have the following positive effects.

+i+H, in the present invention, adhesive fill A, (2
) is molten and the position of the film (3) after being placed on the molten state is ii)
It is extremely easy to handle and does not require skill.

Furthermore, in the present invention, air bubbles are less likely to be generated between the acrylic (1) and the decorative film (3).

Furthermore, unlike conventional adhesives, its viscosity and strength are low at room temperature, so when a film is placed on it, its position can be adjusted freely, and unless heat is applied, this adhesive will not solidify and the position of the film cannot be adjusted. It is possible to fix the difficulty of correcting the position when the film ■ is stuck in several places and wrinkles, air bubbles, etc. occur as in sub-f) u. It is.

Next, in the present invention, acrylic resin plate (1) 1
By adhering the film (3) in close contact with this film, the photographs, pictures, letters, etc. drawn on the film can be clearly seen through the acrylic resin board (υ), resulting in a marked improvement in advertising effectiveness. It was expected.

In addition, the ethylene-vinyl acetate copolymer in the present invention is
Since the lower the molecular weight, the lower the melting temperature and the higher the surface gloss, the use of low-molecular ethylene-vinyl acetate copolymers is also planned.

In addition, the melting point of the acrylic resin is naturally higher than that of the adhesive, and if it is passed through a hot roll at a temperature of 100°C to 150°C for a short time, it will not change in quality to the same extent. The same applies to acetate film, Xjj, paper, etc.

Furthermore, it is well known that ethylene-vinyl acetate 34 polymer has excellent chemical stability, but due to this property, the same thermal properties can be maintained even when peeling or changing the film O) after a long period of time. , which ensured that it could be used repeatedly.

Next, the ethylene-vinyl acetate copolymer has excellent weather resistance, and is resistant to humidity caused by rain, wind, etc.
It also has excellent durability against changes in temperature.

On the other hand, in the past, acrylic resin sand was
Because it was not used, it was discarded, and like plastic waste, it generates high temperatures when burned, which is a disadvantage in terms of disposal. The X-turn of the present invention has made it possible to achieve L7 that can be reused in an innovative manner and to produce signboards at low cost.

The adhesive is a t-determined adhesive containing ethylene-vinyl acetate copolymer as a living body, Kishi silica paper, resin, and two antioxidants.

:i,′! As described in J-, the present invention uses an ethylene-vinyl acetate copolymer adhesive to make the advertising content of display plates on billboards etc. non-changeable.
The purpose of this invention is to provide an effective and novel method for manufacturing and recycling display plates.
