The present invention mainly relates to a method of manufacturing a film-type guide plate used in construction sites and the guide plate as described in more detail, it is possible to easily manufacture a guide plate with excellent discrimination and at the same time a high durability guide plate By allowing them to obtain, they are able to provide guidance signs that last longer.

Generally, a film-type signboard (hereinafter, abbreviated as 'signboard') is required when the signboard is required to be installed at a construction site, but when there is no place to install it or when signs are to be installed at regular intervals or signs. This is used when installing in the air or when the installation and removal of the signs must be prompt. Before and after the signs, patterns, colors, and letters (hereinafter referred to as 'instructions') are variously expressed according to the purpose of guidance.

Such conventional signs are mostly made of a PVC film having light permeability, so that when the sunlight or the headlight of the vehicle is irradiated on the front side, the guides on the rear side are reflected back to the front side, and thus the function of the sign cannot be performed properly. In other words, if the signs on the front of the sign are reflected upside down, the signs on the front of the sign and the signs on the back overlap, so that the signs on the front of the sign cannot be identified at the moment, and the signs cannot be clearly identified. There was a problem that the purpose of the sign installation is faded or lost.

On the other hand, most of the conventional signs are made of a single piece of PVC film, so it is not possible to fundamentally solve the reflection of the notice on the back of the sign, and its durability is also weak, so it is easily damaged (torn, etc.) by strong winds or slight impacts and has a very short lifespan. There was also.

 The present invention has been invented with the technical problem to solve the problems and shortcomings of the conventional signs at the same time as above, in particular, the durability of the signs without the information on the back of the sign signs and good durability and quick / easy to manufacture them It is to provide a way to do this.

This will be described in more detail together with the accompanying drawings as follows.

Method of producing a sign for achieving the technical problem of the present invention,

<Step 1>

 A heat-resistant adhesive of 250 ° C or higher is applied to the back surface of a certain size of heat-resistant polyethylene terephthalate (hereinafter referred to as 'PET') on which a guide letter is expressed. .

<Step 2>

The opaque PET silver foil is attached onto the adhesive of the first step so that the silver foil surface is formed on the back of the PET label.

<Step 3>

  Applying a heat-resistant adhesive of 250 ℃ or more on the silver foil surface of the second step and then attach a low-density polyethylene (hereinafter referred to as "PE") fusion paper on the surface of the adhesive to obtain a sign material (S).

<Step 4>

Fold the sign material S obtained through the third process in half so as to be the basic sign plate G on which the front and rear signs are expressed, and then apply heat to the periphery and the center of the upper base sign plate G inside. It is intended to complete the sign 10 by allowing the PE fusion sheet to be fused to each other, wherein the temperature of the thermal fusion is preferably about 200 ℃ ~ 230 ℃, which is a heat enough to melt the PE fusion sheet, where the melting point of the low density PE fusion sheet Despite the low temperature (about 130 ° C.), the heat of fusion is about 200 ° C. to 230 ° C. because the PE fusion paper receives heat indirectly by the PET label and the PET silver foil paper.

The present invention as described above can obtain a sign material (S) by sequentially applying and attaching the adhesive, PET silver foil, PE fusion paper on the heat-resistant PET label back of a certain size, it is possible to automate the manufacturing process of the sign material, and PET cover of both sides folded by PE fusion paper can be bonded to the basic signboard G obtained by simply folding the signage material S in half to facilitate the process of completing the signage material S into the sign 10. It becomes possible. Bonding of the PET label on both sides in the above is achieved by melting the PE fusion paper on the back of the PET label facing the sign material (S) by folding half.

The sign 10 manufactured through the above-described process is composed of two layers of signs of a conventional sign constituting an opaque PET silver foil laminated on the back of the PET sign of the sign in which various guides are expressed. ) Before and after the back of the PET cover 20, 21, opaque PET foil paper 30, 31, which cannot transmit light, is laminated, and a low density PE fusion paper 50 is disposed between the silver foil papers 30, 31, respectively. ) Is placed in two layers, and the adhesive layer 40 (41) between the PET silver foil paper 30, 31 and the PET cover 20, 21 and between the PET silver foil paper 30, 31 and the PE fusion paper 50. These signs are formed, respectively, the sign 10 is formed before and after the sign 10, the PET sign 20, 21 on the back of the PET silver foil (30, 31) is composed of before and after the sign (10) Even if sunlight or automobile headlights are irradiated on either side, the notices on the surfaces of the PET signs 20 and 21 are reflected on the other PET signs 20 and 21. And the attachment of the above constituent members stacked because the PET cover 20, 21, PET silver foil 30, 31 and PE fusion paper 50 are bonded with the adhesive layer 40, 41 therebetween. This solid, low-density PE fusion paper 50 is placed in two layers between the PET silver foil papers 30 and 31 on both sides, so that the bonding of the PET signs 20 and 21 on both sides can be quickly and easily performed.

In addition, in the present invention, the cover 20, 21 and the silver foil paper 30, 31 of the sign 10 is made of a PET material to be fused to the PE fusion paper 50 inside the sign 10 will be. In other words, in order to smoothly melt the PE fusion paper 50 inside the sign 10, as described above, heat of about 200 ° C. to 230 ° C. needs to be applied, so that the signs 20 and 21 of the sign 10 can be applied. ) Has a melting point of about 256 ℃ higher than the heat of melting, but is suitable as a soft PET material.

Therefore, the present invention can automate the manufacturing process of the sign material (S) as described above, and also the process of manufacturing the sign material (S) as a sign 10 is convenient, so that the sign 10 can be quickly made with minimal manpower. / It can be easily manufactured, as well as the time is shortened, there is an advantage that can reduce the cost of the sign 10, while the sign 10 produced in this way is a double-layered PET sign (20) (21) Since two layers of PET silver foil 30 and 31 are formed in between, and the PE fusion paper 50 is also placed in two layers, the film type sign 10 lasting longer can be obtained. Based on the PET foil paper 30, 31 of the PET cover 20, 21 can completely eliminate the reflection of the guidance of the notice, the notice is distorted or unidentifiable instantaneously or unclear of the notice Identification can be prevented You can also get a sign (10) that can always keep the power excellent.
