Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a transfer sheet that can transfer clear patterns, symbols, etc. to parts other than the ground contact area of a tire, such as the sidewall.

[Problems to be solved by conventional techniques and ideas]

In general, methods for applying chromatic patterns on the outer surface of tires, particularly on areas other than the ground contact area, include white letter tires (white letters embedded in the sidewall), strip-shaped white ribbon tires, etc. In both of these, a colored rubber sheet is attached to the tire sidewall during tire molding, and after vulcanization, the surface is lightly buffed to make the pattern clearer, exposing the colored rubber surface. The work process is complicated.

The object of the present invention is to provide a transfer sheet that can easily form various patterns on the surface of a tire after vulcanization according to the preferences of general users.

[Means to solve the problem]

This invention involves cutting out a black part of the same color as the tire's surface on one side of a base material of release paper or plastic film, and providing a colored part of a different color from the tire's surface in this cut-out part. This is a transfer sheet for a tire, in which a thin rubber layer is releasably attached to the base material, which is vulcanized by natural vulcanization by pressure bonding to the tire surface or by thermocompression bonding, and is transferred to the tire surface.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

The transfer sheet 1 has a thin rubber layer 3 on one side of a base material 2 made of release paper or plastic film.
is pasted. Here, the thin film rubber layer 3 is composed of a rubber compound that is naturally vulcanizable or contains a vulcanization accelerator that has a very high vulcanization rate, such as natural rubber, synthetic rubber, etc., and carbon black 10. This is a composition containing ~50 parts by weight of additives such as anti-aging agents and vulcanization accelerators. Thin rubber layer 3
The tire is composed of a black background part 3a having the same color as the tire surface and a colored part 3b having a different color from the tire surface and expressing a pattern or symbol, and different rubber compositions are used for both parts. Next, the thin rubber layer 3 is made to have a thickness of 1 mm or less to prevent rubber from flowing at the boundaries of the pattern. In order to transfer a pattern to the tire surface using the transfer sheet, the surface of the thin film rubber layer 3 is pressure-bonded or thermo-compressed to the tire surface of a vulcanized tire, for example, the sidewall surface, and then the base material 2 is bonded to the thin film rubber layer 3. This can be done by peeling and removing from 3. As shown in FIG. 1, the colored portion 3b appears on the opposite side to the base material 2 and appears when the base material 2 is peeled off, so the colored portion 3b cuts out the black portion 3a,
It is clear that it is formed in this cutout. When the transfer is carried out by thermocompression using an iron or the like, the thin film rubber layer 3 is vulcanized at the same time, and after a predetermined period of time, the transferred pattern maintains a stable pattern even if the surface is damaged. On the other hand, in the case of transfer by pressure bonding, the pattern of the thin film rubber layer 3 can be stabilized by natural vulcanization. Note that a release sheet may also be provided on the exposed surface of the thin film rubber layer 3 to prevent a decrease in adhesive strength.

[Effect of idea]

As mentioned above, in this invention, the transfer sheet is made of a thin rubber layer with a pattern, so it can be easily transferred to the tire surface, and the user can select any pattern in any place according to his/her preference. You can do it by doing this.

[Brief explanation of the drawing]
