Description

  The present invention relates to a method for manufacturing a logo tag.

  Logo tags are generally constructed of polyvinyl chloride (PVC) plastic. Polyvinyl chloride plastic is easily bonded to an article with an adhesive, but it is necessary to add a stabilizer to the polyvinyl chloride plastic in the manufacturing process. However, since stabilizers contain heavy metals that are harmful to the environment such as cadmium, barium, and lead, severe restrictions are imposed on the use of polyvinyl chloride plastics.

  For this reason, a logo tag made of silicon rubber having thermosetting properties has been developed from an environmentally friendly aspect. However, since this silicone rubber contains silicone oil which is a mold release agent, there is a drawback that it is difficult to bond to an article with an adhesive. In addition, there is a method of fixing such a logo tag to an article by stitching. However, the stitching itself is troublesome, the logo tag may be broken during the work, and articles suitable for stitching are considerably limited. For example, an article such as a metal or a hard object cannot be combined with a logo tag made of silicon rubber by sewing. Therefore, the application range of such a logo tag is considerably limited.

  The present invention has been made in view of the above, and an object thereof is to provide a method of manufacturing a logo tag that can be bonded to another article with an adhesive.

To achieve the above object, the present invention comprises a substrate preparing step of preparing a base material made from fabric material, which can including hardening the hardening agent which can be crosslinked reacting the resin on the substrate A thermosetting resin layer forming step for forming a thermosetting resin layer, and an incomplete curing reaction until the barrier that integrally connects the thermosetting resin layer to the base material is formed , and incomplete curing is performed. A first curing step for forming a layer, a logo pattern unit bonding step for bonding a logo pattern unit containing a thermosetting resin to the incompletely cured layer, and heating the incompletely cured layer and the logo pattern unit. The incompletely cured layer is crosslinked with the thermosetting resin of the logo pattern unit to form a completely cured layer, and the logo pattern unit and the substrate are coupled via the completely cured layer. Including two curing steps To provide a method of manufacturing a logo tag characterized by.

  According to the logo tag manufacturing method of the present invention, since the curable thermosetting resin layer in the thermosetting resin layer forming step is one that cannot always penetrate the substrate even during a crosslinking reaction. The adhesiveness of the adhesive surface which is the opposite surface of the substrate is not adversely affected. In addition, since the curable thermosetting resin layer includes a curing agent that can crosslink the resin, the thermosetting resin layer is incompletely crosslinked in the first curing step. In addition, since a barrier integrally connected to the substrate can be formed, both the incompletely cured layer and the material of the logo pattern unit can be formed in the second curing step. It is blocked by the barrier and does not enter the substrate, and does not adversely affect the adhesion of the adhesive surface that is the opposite surface of the substrate. Therefore, it can be bonded to the article at the substrate by the adhesive. In addition, the thermosetting resin layer may be, for example, one that has low fluidity and cannot always penetrate the substrate even during the crosslinking reaction, and becomes silicon rubber by the crosslinking reaction.

  Hereinafter, a preferred embodiment of a logo tag manufacturing method of the present invention will be described with reference to the drawings.

  First, a first embodiment of the present invention will be described with reference to FIGS.

  In this 1st Embodiment, as shown in FIG.1 and FIG.2, first, the base material 10 which consists of cloth materials is prepared (base material preparation process). As shown in FIG. 2, the base material 10 has a rough surface 11 composed of a plurality of fine yarns 13 and an adhesive surface 12 that is the opposite surface and adheres to the article. As the material of the base material 10, for example, heat-resistant materials such as leather, woven fabric, knitted fabric, and non-woven fabric, or one or more composite / mixed components thereof can be used.

  A curable thermosetting resin layer 20 that contains a curing agent capable of crosslinking the resin on the rough surface 11 of the substrate 10 and cannot always penetrate the substrate 10 even during the crosslinking reaction. Form (thermosetting resin layer forming step). In the present embodiment, the thermosetting resin layer that becomes silicon rubber by a crosslinking reaction is used. A high temperature curing agent is used as the curing agent.

  Next, as shown in FIG. 3, the thermosetting resin layer 20 is heated with a heater 300 until a barrier integrally connected to the rough surface 11 of the substrate 10 is formed, and the degree of the crosslinking reaction is determined by the heating time. Is controlled to cause an incomplete crosslinking reaction to form the incompletely cured layer 21 (first curing step). In this embodiment, the case where a high temperature curing agent is used as the curing agent and the first curing step is performed by heating and the degree of the crosslinking reaction is controlled by heating time has been described. A curing agent may be used, and the first curing step may naturally cause the incomplete crosslinking reaction at room temperature.

  Then, the logo pattern unit 30 containing the thermosetting resin is bonded to the incompletely cured layer 21 (logo pattern unit bonding step). More specifically, the logo pattern unit 30 is composed of an adhesive layer 31 containing a thermosetting resin and a plurality of logo sheets 32 on the lower surface of the adhesive layer 31. After placing the adhesive layer 31 on the plurality of logo sheets 32 after being placed in the mold 200, the base material 10 on which the incompletely cured layer 21 is placed is placed in the mold 200 and the incompletely cured layer 21. Is adhered to the adhesive layer 31. The adhesive layer 31 is made of silicon rubber by a crosslinking reaction.

  Then, the incompletely cured layer 21 and the logo pattern unit 30 are heated to crosslink the incompletely cured layer 21 with the thermosetting resin of the logo pattern unit 30 to form a completely cured layer 22. And the base material 10 are connected via the fully cured layer 22 (second curing step). In the process of performing the second curing step, neither the incompletely cured layer 21 nor the material of the logo pattern unit 30 is blocked by the barrier integrally connected to the base material 10 and does not enter the base material. The adhesiveness of the surface 12 is not adversely affected. Finally, as shown in FIG. 5, the substrate 10, the fully cured layer 22 adhered to the rough surface 11 of the substrate 10, and the logo pattern unit 30 adhered to the completely cured layer were included. A logo tag 40 is obtained.

  Next, FIG. 6 and FIG. 7 show a second embodiment of the present invention. The manufacturing method of the logo tag of the present embodiment is almost the same as the manufacturing method of the first embodiment, except for the thermosetting resin layer forming step.

  More specifically, as shown in the figure, in this thermosetting resin layer forming step, the thermosetting resin layer 20 is on the rough surface of the substrate 10 and the concentration of the curing agent is the same as that of the first embodiment. The first sub-thermosetting resin layer 201 included in the first sub-thermosetting resin layer 201 and the first sub-thermosetting resin layer 201 on the first sub-thermosetting resin layer 201, the concentration of the same curing agent as in the first embodiment is low. A layer made of the second sub-thermosetting resin layer 202 is formed. Since the concentration of the curing agent contained in the second sub-thermosetting resin layer 202 is lower than that of the first sub-thermosetting resin layer 201, the time required for the crosslinking reaction of the second sub-thermosetting resin layer 202 Is longer than the first sub-thermosetting resin layer 201. Therefore, in the first curing step, the first sub-thermosetting resin layer 201 is completely cross-linked with the curing agent having a relatively high concentration to form a barrier similar to that in the first embodiment. In addition, the second sub-thermosetting resin layer 202 is incompletely cured by the incomplete crosslinking reaction with the curing agent having a relatively low concentration. In this case, the first sub-thermosetting resin layer 201 includes the curing agent in a concentration of 5% to 10%, and the second sub-thermosetting resin layer 202 includes the curing agent in a concentration of 5% to 10%. It is preferable. In this embodiment, the first sub-thermosetting resin layer 201 contains the curing agent at a concentration of 10%, and the second sub-thermosetting resin layer 202 contains the curing agent at a concentration of 5%.

  As can be seen from the above-described embodiment, in the method for producing a logo tag of the present invention, the base material can always penetrate the cross-linking reaction as the curable thermosetting resin layer in the thermosetting resin layer forming step. Since those which cannot be used are used, the adhesiveness of the adhesive surface which is the opposite surface of the substrate is not adversely affected. Moreover, since the thing containing the hardening | curing agent which can carry out the crosslinking reaction of the resin is used as the said curable thermosetting resin layer, the said thermosetting resin layer is incompletely bridge | crosslinked in the said 1st hardening process. In addition, since a barrier integrally connected to the substrate can be formed, the incompletely cured layer and the material of the logo pattern unit can be formed in the second curing step. It is blocked by the barrier and does not enter the substrate, and does not adversely affect the adhesion of the adhesive surface that is the opposite surface of the substrate. Therefore, the logo tag according to the manufacturing method of the present invention can be bonded to the article with the base material by the adhesive.
