Abstract
Provided are a pneumatic tire and a method for manufacturing the same. At least one sensor unit including a sensor that acquires tire information is fixed to a tire inner surface via an adhesive layer, and an amount of silicon in a release agent detected by fluorescent X-ray analysis at least in a fixing region for the sensor unit is from 0.1 wt % to 10.0 wt %.
Claims8
A pneumatic tire, comprising:
- at least one sensor unit fixed to a tire inner surface via an adhesive layer and comprising a sensor that acquires tire information, an amount of silicon in a release agent detected by fluorescent X-ray analysis at least in a fixing region for the at least one sensor unit being from 0.1 wt % to 10.0 wt %;
- wherein
- the adhesive layer is made of a cyanoacrylate-based adhesive,
- an adhesive strength of the adhesive layer ranges from 0.4 N/mm2 to 1.5 N/mm2, and
- the release agent consists only of one or more selected from the group consisting of a dialkyl polysiloxane, an alkylphenyl polysiloxane, an alkylaralkyl polysiloxane, a 3,3,3-trifluoropropylmethyl polysiloxane, or combinations thereof.
A method for manufacturing a pneumatic tire that comprises vulcanizing a green tire by using a bladder comprising a coating layer made of a release agent, the method comprising:
- in fixing a sensor unit to an inner surface of a tread portion of a vulcanized pneumatic tire, setting an amount of silicon in the release agent detected by fluorescent X-ray analysis at least in a fixing region for the sensor unit to from 0.1 wt % to 10.0 wt %, and fixing the sensor unit to the fixing region for the sensor unit via an adhesive layer;
- wherein
- an adhesive strength of the adhesive layer ranges from 0.4 N/mm2 to 1.5 N/mm2, and
- the release agent consists only of one or more selected from the group consisting of a dialkyl polysiloxane, an alkylphenyl polysiloxane, an alkylaralkyl polysiloxane, a 3,3,3-trifluoropropylmethyl polysiloxane, or combinations thereof.
A method for manufacturing a pneumatic tire, the method comprising, in fixing a sensor unit to a tire inner surface, setting an amount of silicon in a release agent detected by fluorescent X-ray analysis at least in a fixing region for the sensor unit to from 0.1 wt % to 10.0 wt %, and fixing the sensor unit to the fixing region for the sensor unit via an adhesive layer;
- an adhesive strength of the adhesive layer ranges from 0.4 N/mm2 to 1.5 N/mm2, and
- the release agent consists only of one or more selected from the group consisting of a dialkyl polysiloxane, an alkylphenyl polysiloxane, an alkylaralkyl polysiloxane, a 3,3,3-trifluoropropylmethyl polysiloxane, or combinations thereof.
A pneumatic tire, comprising:
- at least one sensor unit fixed to a tire inner surface via an adhesive layer and comprising a sensor that acquires tire information, an amount of silicon in a release agent detected by fluorescent X-ray analysis at least in a fixing region for the at least one sensor unit being from 0.1 wt % to 10.0 wt %;
- wherein
- the adhesive layer includes an epoxy resin or a urethane resin,
- an adhesive strength of the adhesive layer ranges from 0.4 N/mm2 to 1.5 N/mm2, and
- the release agent consists only of one or more selected from the group consisting of a dialkyl polysiloxane, an alkylphenyl polysiloxane, an alkylaralkyl polysiloxane, a 3,3,3-trifluoropropylmethyl polysiloxane, or combinations thereof.
