Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an adhesive material and a method for manufacturing the adhesive material, and in particular, to the surface of continuous paper used to continuously form single pieces forming postcards, for example. The present invention relates to an adhesive material that can be attached to the surface of confidential information, etc., and at least a portion of the adhesive material can be peeled off as needed, and a method for manufacturing the adhesive material.

(Prior art) Particularly in recent years, there has been an increase in the number of mail items containing confidential information, such as notices of bank deposit balances, etc. However, the field for writing confidential information is hidden during mailing, and official receipts are not accepted. Postcards have been developed in such a way that a person can relatively easily view the contents of the postcard after receiving it.

Conventional methods in which a covering material is adhered to the surface of a single piece of postcard include those in which a pressure-sensitive adhesive layer formed on the back side of the covering material is adhered to a single piece of postcard size by applying pressure.

(Problems to be Solved by the Invention) However, in the case where a covering material with such a pressure-sensitive adhesive layer formed on the back side is attached to a part of a single postcard,
During manufacturing, the pressure-sensitive adhesive layer of the covering material is attached to the surface of a single postcard piece with slight contact, so even if the tip of the covering material is not located at the optimal position on the single postcard piece, Initial bonding is done and stuck in the correct position.

There is a high probability that so-called pasting errors will occur. Moreover, in the case of a coating material formed from a conventional pressure-sensitive adhesive layer, in order to make the coating material removable from the surface of a single postcard, the surface of the single postcard must be coated with silicone, etc. Since a separate peeling process is required, it is necessary to process one side of the postcard in addition to the processing of the covering material, leading to an increase in manufacturing costs.

Therefore, the main purpose of the present invention is to make it possible to paste the material at the optimal position on the material to be pasted, and to eliminate the need for a peeling process or the like on the material to be pasted, such as a postcard mount. The purpose is to provide an adhesive material and a method for manufacturing the same.

(Means for Solving the Problems) In the first invention, a release agent layer is formed on at least a part of the surface of the base material, and is thermally bonded to the main surface of the release agent layer of the base material. This is an adhesive material on which a synthetic resin layer is formed.

The second aspect of the present invention includes a step of preparing a base material of an appropriate size, a step of preparing an adhesive material having a heat-adhesive resin layer formed on the back surface thereof, and a step of preparing at least a surface of the base material. A step of forming a release agent layer by printing/coating a release agent layer in part; a step of printing/coating a molten thermal adhesive resin on the main surface of the release agent layer side of the base material; This is a method for producing an adhesive material, including a step of solidifying a molten thermoadhesive resin of a base material.

(Function) The thermoadhesive resin layer formed on the back side of the adhesive material is heated and pressurized on the surface of the material to be adhered, so that the thermoadhesive resin layer melts and adheres to the material. glued to the material. The release agent layer formed between the base material and the heat-adhesive resin layer functions to separate the base material from the heat-adhesive resin layer.

(Effects of the Invention) According to the present invention, the adhesive material is configured to adhere to the main surface of the material to be adhered by melting the heat-adhesive resin layer formed on the back surface of the material by heating. If the adhesive material is heated only after it is confirmed that the adhesive material is superimposed on the surface of the material to be adhered at the optimal position, the adhesive material can be accurately adhered to the optimal position on the surface of the material to be adhered. Moreover, it is possible to create a difference in adhesive strength by forming a release agent layer between the heat-adhesive resin layer and the base material on the surface of the material to be adhered, without requiring any peeling treatment or the like. Since the adhesive can be configured so that it can be peeled off at least in that part, for example, there is no need for a separate special peeling process (and manufacturing costs can be reduced).

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Example) FIG. 1A is a perspective view of an adhesive material that is an example of the present invention.

FIG. 1B is a partial cross-sectional view of the embodiment.

This adhesive material 1O includes a base material 12 made of a relatively flexible material such as paper or a synthetic resin film that can be cut with scissors or the like.

A concealing layer 14 is formed on one main surface of the base material 12.

The hiding layer 14 is formed, for example, by silver printing with silver ink or the like, or by laminating film materials having hiding power such as aluminum foil with an adhesive or the like.

A part of the surface of the concealing layer 14 is formed with a release agent layer 16 coated with a release agent such as silicone resin, fluorine resin, paraffin, wax, or the like.

The release agent layer side surface of the hiding layer 14 is further coated with a thermoadhesive resin by extrusion while heating, or by dissolving it in a solvent or dispersing it in water and printing with gravure or silk screen. , a thermal adhesive resin layer 18 is formed.

The thermal adhesive resin NlB of 2 is melted at a temperature of, for example, 100° C. to 200° C., and is formed so as to be able to completely adhere to the material to be adhered.

Then, the adhesive material 10 is further placed on the width direction side of the continuous base paper 20a.
There is a spot bonding portion 26 in which the release agent layer 16 is not formed so that the thermal adhesive resin layer 18 and the hiding layer 14 of the base material 12 are directly bonded to each other in a spot shape at the tip of the substrate. Therefore, in the part where the release agent layer 16 is formed,
The base material 12 and the thermoadhesive resin layer 18 are weakly bonded, and the base material 12 is weakly bonded to the base material 12 in the portion where the release agent layer 16 is not formed.
and the heat-adhesive resin layer 18 are strongly adhered to each other. Incidentally, in the above embodiment, the spot adhesive portion 26 is the adhesive material 10.
Although the spot adhesive part 26 is formed on the tip of the adhesive material, it may be formed on either the tip or the rear end. 10, where the heat-adhesive resin layer 18 is exposed over the entire surface with a certain width is attached to the spot adhesive part 2.
It may be replaced with 6.

In addition to the above embodiments, examples of the base material 12 include synthetic paper, cellophane, polyethylene, polyester films, aluminum foil, etc., but this adhesive material IO
When the adhesive material 10 is applied to the continuous base paper 20a, the adhesive material 10 is applied to the continuous base paper 20a to prevent the adhesive material 10 from inadvertently peeling off between the eyebrows against the adhesive force of the heat-adhesive resin layer 18 in the area where the release agent layer 16 is formed. It is best to choose one that is flexible.

Furthermore, if a material with excellent hiding properties, such as aluminum foil, is selected as the base material 12, it is not necessary to form the hiding layer 14 as in the previous embodiment.

As an example of the adhesive resin, an EVA adhesive is selected. Its composition consists of E, VA (ethylene-vinyl acetate copolymer resin), tackifier, wax, and antioxidant, and a plasticizer and filler may be added as supplementary agents.

Examples of the tackifier include glycerin ester of partially hydrogenated rosin, glycerin ester of rosin, pentaerythritol modified rosin, petroleum resin, α-methylstyrene/vinyltoluene copolymer, chirhen oil polymer, and terpene phenol polymer.

Examples of the wax include paraffin wax, microcrystalline wax, low molecular weight polyethylene wax, Fischer-Tropsch wax, Castor wax, and chlorinated paraffin.

Examples of antioxidants include hindered phenol compounds, salicylic acid compounds, benzophenone compounds, benzotriazole compounds, phosphorus compounds, sulfur compounds, and organometallic compounds.

Examples of adhesive resins other than the above examples include styrene-butadiene-styrene copolymer resin, styrene-isoprene-
Styrene copolymer resin, polyethylene, ethylene-ethyl acrylate copolymer resin, ethylene-acrylic acid copolymer resin, ethylene-methyl acrylate copolymer resin, ethylene-methyl methacrylate copolymer resin, ethylene-methacrylic acid copolymer resin, ionomer resin , polymethylpentene resin, ethylene-vinyl alcohol copolymer resin,

When printing or coating these, they may be used as appropriate while being heated, dissolved in a solvent, or dispersed in water.

Next, a method for manufacturing this adhesive material 10 will be explained based on FIGS. 4 to 6.

First, a paper forming the base material 12 is prepared, and the hiding layer 14 is formed on the main surface thereof by solid silver printing with silver ink, for example, by a well-known printing method such as offset printing, or by coating. do.

The base material 12 on which the hiding layer 14 has been formed is then led to a release agent coating device 30, as shown in FIG. The release agent coating device 30 coats the surface of the base material 12 on the hiding layer 14 side.
For example, it is used for printing and applying a release agent 16a such as silicone resin, fluorocarbon resin, paraffin, Wanx, etc., and includes a holding roller 32 for holding the base material 12 in a roll shape. The base material 12 held by the holding roller 32 is guided to a coating device 38 including two rollers 34a and 34b1 storage tank 36, and the release agent 16a is applied while rotating the rollers 34a and 34b.

The reason why temperature control is performed for each heater in this way is to allow delicate adjustments to be made depending on the characteristics of the thermal adhesive resin layer formed on the adhesive material 10.

Next, regarding the operating state of the adhesive device for this adhesive material, the first
This will be explained with reference to the time chart shown in FIG.

The continuous base paper 20a is transferred by a predetermined amount by the sprocket transfer device 106 of the continuous paper transfer device 102.

In this embodiment, the adhesive portion transfer table 118 moves from the downstream side to the upstream side of the continuous base paper 20a.

On the other hand, the adhesive material transfer device 120 transfers the adhesive material continuum 10a from the reel 122, and the adhesive material detection device 124 detects the detection mark formed on the surface of the adhesive material continuum 10a. In the example, by detecting the arrow, the transfer of the adhesive material continuous body 10a is temporarily stopped, and the adhesive portion transfer table 118 is also stopped.

At this time, the adhesive material cutting device 126 is activated and the cutter 1
30a and 130b, by the action of the cam groove of the disc 142, adjust the adhesive material continuum 10a to an appropriate size, that is, -
Cut the adhesive material 10 into pieces.

Then, the tip of the adhesive material 10 cut into an appropriate size by the adhesive material cutting device 126 is located at an optimal position on the surface of the continuous base paper 20a, and is positioned along the line forming the pressurized and heated bag H150. The leading end of the continuous base paper 20a is pressurized and heated in a straight line in the width direction of the continuous base paper 20a in a pressurized and heated bag W152, and the front end of the adhesive material 10 is initially adhered to the surface of the continuous base paper 20a.

At this time, simultaneously with the pressurization and heating, the continuous base paper 20a is transferred downstream by a certain distance, which in this embodiment is approximately equivalent to the length of a piece of adhesive material 10, by the operation of the continuous paper transfer bag W102. That is, at the same time that the adhesive material lO and the single piece 22 located at the lower part of the planar pressurizing and heating device 154 in the previous cycle are pressurized and heated, the adhesive material is 10 will be transported a predetermined distance.

After the adhesive portion transfer table 118 moves a predetermined amount on the rail body 174, the linear pressure heating device 152 and the planar pressure heating device 15 are again moved by the action of the cam groove of the disc 172.
4 is located above and apart from the bonding portion transfer table 118. At the same time, the linear pressure and heating device 152 and the planar pressure and heating device 154 move together with the adhesive portion transfer table 118 in the direction opposite to the flow of the continuous base paper 20a, that is, to the original predetermined position on the upstream side. . At this time, the pressure roller 16
2 rotates and presses the surface of the adhesive material 10.

Then, after the process of cutting the adhesive material 10, etc., the adhesive part transfer table 118 and the pressure heating device 150 are formed at the tip position of the adhesive material 10 sent later in the next cycle. The linear pressure and heating device 152 and the planar pressure and heating device 154 are joined.

At this time, the adhesive material 14 sent in the previous cycle is located at the lower part of the planar pressure heating device 154. Then, the continuous base paper 20a to which the tip of the adhesive material 10 for the next cycle has been adhered is transported a certain distance by the operation of the continuous paper transport device 102, and the continuous base paper 20a that has been pasted in the previous cycle is The material 10 is pressed and heated by the planar pressing and heating device 154.

That is, when the adhesive material 10 whose tip is adhered is located at the lower part (initial upstream position) of the planar pressure and heating device 154, the planar pressure and heating device 154 transfers the adhesive part. The adhesive material 10 is pressed against the surface of the base 118 by the action of the cam groove formed in the disc 172, and the adhesive material 10 is heated under pressure.

Note that the transport distance of the continuous base paper 20a is also the same as that of the continuous paper transport device 1.
The transfer distance is regulated by pulses generated by the encoder formed at 02, and the central processing unit 176
It is configured to control the transfer of the adhesive material transfer device 120, the adhesive material cutting device 126, and the pressure heating device 150. However, the continuous base paper 20a is formed so as not to move backward, and in response to the backward movement of the bonding portion transfer table 118, the linear pressure heating device 152 of the pressure heating device 150, and the planar pressure heating device 154, it is not moved backward. It is formed like this.

In this way, the pressurizing and heating device 150 repeats the cycle of forward movement, consideration point (downstream side), backward movement, consideration point (upstream side), and as shown in FIG. The adhesive material 10 is adhered to the surface of the piece 22 as appropriate.

Then, the continuous base paper 20a partially covered with the adhesive material 10 in this manner is folded as appropriate, then cut off as appropriate, and submitted to a post office.

Note that the continuous base paper 20a to which this adhesive material 10 is attached is as follows:
The base material 12 is strongly adhered to the single piece 22 in the portion where the thermally adhesive resin layer 18 and the base material 12 are directly adhered, and the base material 12 is weakly adhered to the portion where the release agent layer 16 is formed. Therefore, as shown in FIGS. 13a and 13B, in the portion where the release agent layer 16 is formed,
