Definitions

  • the invention relates to a sealant layer assembly to allow the sealant layer be applied outside of the tyre production line.
  • a sealant layer can be applied at the premises of tyre dealers and also on any type of tyre requested by customers, hence without being linked to production limits.
  • the use of a viscous sealant layer generally arranged in the inner cavity of the tyre has been known for a long time.
  • the sealant layer is arranged in contact with the inner liner layer, in the area of the tread band.
  • the function of the sealant layer is that of creating a sort of instantaneous "seal" around the object that penetrated the tread, thus preventing air from flowing out of the tyre. Furthermore, in case the aforesaid object comes out, the material of the sealant layer has the function of filling the hole left by the object, hence sealing it.
  • the viscosity of the sealant layer is one of the most important parameters that allow it to effectively carry out the tasks described above. Indeed, the viscosity of the sealant layer must be such as to ensure both the sealing action to be exerted upon the object that penetrated the tread and the hole left by the object itself in a very short time, as discussed above, and its dimensional stability in the inner cavity of the tyre during the rolling phase or the standing phase of the tyre. Because of its function, the sealant layer is particularly sticky and has low viscosity and, for this reason, hard to be handled when it is separate from the tyre. This is why generally the sealant layer, is applied directly on the surface of the inner liner, typically in the tyre production line.
  • the subject of the invention is a sealant layer assembly which allows a sealant layer to be applied on an inner cavity of a tyre on the outside of tyre production plants; said assembly comprises: (i) a sealant layer to be applied with its first surface on the surface of an inner liner layer facing the inner cavity of a tyre and made up of a rubber layer whose viscosity is such as to create an instantaneous "seal" around an object that penetrated a tread or closing the hole left by the object, (ii) a net layer arranged on said first surface of the sealant layer to be, in use, interposed between the sealant layer and the surface of the inner liner layer facing the inner cavity of the tyre, and (iii) one non-stick protective layer arranged on said net layer; said net layer having meshes each of which has an area ranging from 0.25 mm 2 to 25 mm 2 .
  • sealant layer means a rubber layer to be arranged on the surface of the inner liner facing the inner cavity and whose viscosity is such as to create an instantaneous "seal" around the object that penetrated the tread, thus preventing air from flowing out of the tyre or closing the hole left by the object.
  • said assembly comprises a second non-stick protection layer, arranged on a second surface of the sealant layer .
  • the net layer is made of a synthetic or natural polymer material .
  • the net layer is made of a material comprised in the group consisting of polyethylene, polypropylene, polyethylene terephthalate, nylon, Kevlar®, and Rayon.
  • the sealant layer has a thickness ranging from 2 to 5 mm.
  • the non-stick protective layer is a one sided silicone paper.
  • the protective layer is made of a material chosen in the group consisting of paper, metal film and plastic film on which a surface treatment has carried out; said surface treatment being carried out by a material chosen in the group consisting of silicon, paraffin, fluoropolymers, polyethylene.
  • a compound was prepared in order to manufacture a sealant layer, whose phr composition is shown in Table I.
  • the halobutyl rubber is a bromobutyl rubber.
  • the type of carbon black used is identified with N550.
  • the plasticizer used is naphthenic oil.
  • the accelerator used is dibenzothiazyl disulfide (MBTS ) .
  • the assembly manufacturing procedure involved a first coupling step to couple a net layer and a non-stick protective paper to one another and, subseguently, a second coupling step, during which a sealant layer is applied to the net layer already coupled to the non-stick protective paper.
  • the process took place at a temperature of 85°C.
  • the process must take place at a temperature ranging from 60 to 110°C.
  • the temperature was guickly reduced to -5 °C.
  • the temperature is reduced below 10°C and, more preferably, below 0°C, so as to get close to the Tg of the sealant material.
  • the net layer used is made of polypropylene, whose meshes have the shape of a rhombus with an area of 9 mm 2 .
  • the non-stick protective layer is a one-sided silicone paper with a 135g basis weight produced by "Rossella s.r.l.”.
  • the assembly was wound so as to form a roll and then stored.
  • a strip with suitable dimensions is cut out of the assembly preserved at a low temperature.
  • the strip is heated until it reaches a temperature ranging from 40°C to 80°C (preferably 50°C).
  • the heating is obtained by means of an IR radiation (1000 W arranged at a 1 m distance for 20 min), so as to obtain a merely superficial heating, or by means of an oven at 50°C for 10 minutes.
  • the non-stick protective layer under the net layer must be removed and material strip must be applied in the desired position on the inner liner (net layer arranged in contact with the inner liner) applying pressure to ensure the adhesion.
  • the protective layer arranged on the sealant layer is removed as well, if present.
  • the tyre is fitted on the rim and inflated up to the operating pressure.
  • the net layer for it does not adhere to the inner liner or adheres to it to a smaller extent compared to the sealant layer, can be more easily removed and, by pulling it away from the inner liner, ensures an easier removal of the sealant layer. Therefore, upon disposal of the tyre, it is sufficient to make a cut in the sealant layer so as to expose the net layer and, hence, remove it together with the sealant layer .
