  Moreover, in this invention, even when it uses the adhesive which requires time for hardening, low-speed driving | running | working is possible immediately after label sticking with the adhesive force of the adhesive sheet which has fixed the label. Furthermore, since the amount of adhesive applied can be regulated, the amount of adhesive protruding can be reduced to almost zero, which is also preferable in appearance, and the amount of adhesive applied affects adhesive performance. Adhesion reliability can be improved.

  Hereinafter, the label sticking method and the label sticking support to the tire of the present invention will be described in more detail.

  In order to carry out the label sticking method to the tire of the present invention, first, on the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet, a release paper having a hole portion substantially the same shape as the outer shape of the label stuck to the tire, A label affixing support that is temporarily fixed by the adhesive force of the pressure-sensitive adhesive sheet, and has a label having a thickness smaller than the thickness of the release paper temporarily fixed on the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet in the hole of the release paper 2A, the release paper 5 is temporarily fixed on the adhesive surface (shown by a thick solid line) of the adhesive sheet 4 as schematically shown in FIG. An inner hole portion 9 is opened.

  From this state, as shown in FIG. 2B, the label 6 desired to be attached to the bottom of the center hole portion 9 is placed with the label front side facing the adhesive sheet 4 side. The label 6 has a thickness smaller than that of the release paper 5. Then, the adhesive layer 7 is formed by applying an adhesive or the like on the height difference (thickness difference) portion from the state, and if necessary, the surface portion of the adhesive layer 7 is flattened or slightly After the surface is hardened, the surrounding release paper 5 is removed, and the label 6 is attached to the tire sidewall through the adhesive layer 7 together with the adhesive sheet 4. Then, after the adhesive layer 7 is cured, the pressure-sensitive adhesive sheet 4 is peeled off.

  The adhesive sheet 4 will adhere to the tire around the label while firmly covering the 4 parts of the label until the curing is completed, and the label may be fixed so that it does not move firmly during the curing. Also, it plays a role of preventing the adhesive from protruding from the adhesive layer 7. The adhesive sheet 4 may be a long and narrow adhesive tape, and the release paper 5 and the label 6 can be seen through the adhesive sheet 4 or the application position can be easily seen and the application position can be easily positioned. Thus, it is preferable to consist of a transparent or translucent resin sheet.

  As the adhesive, it is preferable to use a room-temperature curable adhesive because it can be easily pasted by the user, and it has a high adhesive strength so that it can be adapted to tire deformation accompanying road running after pasting. It is preferable to use an elastic adhesive that has both flexibility and flexibility.

  Further, since the adhesive 7 is applied so as to fill the height difference portion between the label 6 in the center hole portion 9 and the release paper 5, the adhesive 7 has a medium to high viscosity to a certain extent than that having a very low viscosity at the time of application. According to the study by the present inventors, the viscosity measured by a BS viscometer is preferably 500 to 4000 Pa · s and the thixo index (1 rpm / 10 rpm) is 3 in an atmosphere of 20 ° C. 0.0 to 7.5 adhesives are used. If the viscosity is lower than the above range, the adhesive tends to sag and the workability is lowered, and if it is too high, the mixing and extruding properties of the adhesive are deteriorated, and the workability and practicality are not good.

  The release paper 5 is preferably flexible in that it is attached to a tire sidewall portion having a curved surface.

  Since the adhesive 7 is immediately covered with the pressure-sensitive adhesive sheet after application, the adhesive 7 is cured while being shielded from the outside air. Therefore, a two-component reactive adhesive is more preferable than a one-component moisture-curable adhesive from the viewpoint of developing adhesive strength. However, when a special pressure-sensitive adhesive sheet having air permeability and moisture permeability is used, a one-component moisture-curable adhesive can also be used.

  The kind of the base material sheet of the pressure-sensitive adhesive sheet 4 is not particularly limited, and any of vinyl chloride, polypropylene, polyester, urethane, acrylic, silicone, rubber, and the like can be used. Especially, it is preferable that it has flexibility from a viewpoint of sticking to the tire sidewall which has curved surfaces, and a viewpoint of following the deformation | transformation of a tire. The kind of the adhesive material of the adhesive sheet is not particularly limited, and any of acrylic, rubber, and silicone can be used. A rubber-based pressure-sensitive adhesive is preferable from the viewpoint of sticking to a tire that is a rubber product.

  Moreover, since the thickness of the release paper 5 shall be thicker than the thickness of the label 6, generally it is preferable that it is the range of thickness 1-5 mm. The label can be made of polyurethane or rubber (NR, CR, NBR, SBR, etc.), and the thickness is about 0.5 to 3 mm. preferable. Further, it is preferable to determine the thickness of the release paper 5 so that the adhesive application thickness is 0.1 to 2 mm.

  The label sticking support to the tire of claim 5 of the present invention is close to the state of FIG. 2 (b), but is in a state where the adhesive layer 7 is not yet filled. In that state, it is easier to distribute, and it is possible for the tire user to apply the label to apply and form the adhesive layer 7 just before application, which causes the adhesive to harden before application. It is because it is preferable without causing.

  In order to form the inner hole portion 9, as shown in FIG. 2C, a perforation 10 that matches the outer shape of the label 6 is formed on the release paper 5, and is surrounded by the perforation 10. By removing the release paper portion 5 ′, the inner hole portion 9 can be formed. 2A and 2B are cross-sectional views as viewed from the AA ′ direction in FIG.

  In carrying out the present invention, the release paper portion 5 'may be removed to form the inner hole portion 9, and then the label 6 may be placed on the bottom thereof. The label 6 is placed on the inner bottom portion of the middle hole portion 9, and a release paper portion 5 'having a thickness corresponding to the thickness of the adhesive layer 7 is provided thereon, and the release paper portion 5' is removed. At the same time, the rear surface of the label 6 may appear.

  As described above, according to the present invention, it is possible to apply a desired label beautifully and easily without soiling or sticking fingers with an adhesive or the like. In addition, even when an adhesive that requires time to cure is used, there is no problem such as the label edge during the curing of the adhesive floating due to the adhesive strength of the adhesive sheet fixing the label, and the label It is possible to run at a low speed even immediately after pasting. In addition, since the amount of adhesive applied can be regulated, the amount of adhesive protruding can be reduced to almost zero, which is preferable in terms of appearance, and the amount of adhesive applied affects adhesive performance. This brings about the advantage that the reliability of adhesion can be improved.
