A pneumatic vehicle tire is provided. The tire includes a tread, an inner surface lying opposite the tread, a self-sealing sealant and a sound-absorbing open-cell foam ring arranged inside the pneumatic vehicle tire. The foam ring is adhesively attached to the inner surface and adheres to the self-sealing sealant which is applied before the sound-absorbing open-cell foam ring is attached to the inner surface. The self-sealing sealant has, at least immediately after being applied, a tackiness required for an adhesive attachment of the sound-absorbing open-cell foam ring. A closed-cell material ring is arranged between the sound-absorbing foam ring and the self-sealing sealant to prevent a diffusion of the sealant into the open-cell foam ring. The closed-cell material ring effects an airtight condition.

Self-sealing tire sealants are provided which contain fragments and/or residues of expanded solids, where the solids are selected from the group containing expandable graphite and microspheres. In some aspects, the microspheres include at least isobutane and/or isopentane as blowing agents. The microspheres may also have a shell containing at least one polymer, and in some cases the polymer is at least one copolymer of acrylonitrile and methyl acrylate. The self-sealing tire sealant may further include graphene structures. In some aspects the interior of a pneumatic vehicle tire has the self-sealing tire sealant disposed on the inner surface, opposite the tire tread, and the layer thickness of the tire sealant may be from 0.5 to 8 mm.

Self-sealing tire sealant and pneumatic vehicle tire

The invention relates to a method for the production of a tire sealant (C) with a polymeric base. A highly viscous first sealant component (A) (including a natural rubber component that is undiluted or diluted with at least one additional natural rubber component and mixture ingredients that are free of a solvent and an activator) is mixed with at least one second sealant component (B) (comprising a separately produced medium with low viscosity containing at least one activator), to combine to the tire sealant (C), wherein a cross linking occurs associated with the subsequent application of the tire sealant (C) to the inside of the tire. Appropriate method steps are disclosed.
