Abstract
A method of preparing a tire including the steps of: providing a cured tire, the tire including a first bead, a second bead, a carcass layer extending from the first bead to the second bead, and an optional innerliner layer disposed interior to the carcass layer; applying a pair of reinforcing members to the carcass layer or to the optional innerliner layer, if present; and applying an air barrier composition to the pair of reinforcing members, and to a portion of the carcass layer or to a portion of the optional innerliner layer to thereby form an air barrier layer.
Claims9
A method of preparing a tire, the method comprising steps of:
- (i) providing a cured tire, the cured tire including a first bead, a second bead, a carcass layer extending from the first bead to the second bead, and an innerliner layer disposed interior to the carcass layer;
- (ii) applying a pair of reinforcing members to the innerliner layer of the cured tire;
- and
- (iii) applying an air barrier composition to the pair of reinforcing members with the cured tire, and to a portion of the innerliner layer of the cured tire to thereby form an air barrier layer on the cured tire, wherein the air barrier layer is a phase-separated polymeric system wherein an elastomeric component is phase separated from a thermoplastic component, wherein the air barrier layer includes a permeability to oxygen (P(O2)) of less than 250 cc·mm/m2·day·atm as measured in accordance with ASTM method F1927-14.
A method of preparing a tire, the method comprising steps of:
- (i) providing a cured tire, the cured tire including a first bead, a second bead, a carcass layer extending from the first bead to the second bead, and an innerliner layer disposed interior to the carcass layer;
- (ii) applying a pair of reinforcing members to the innerliner layer of the cured tire, each of the pair of reinforcing members having a first longitudinal edge;
- and
- (iii) applying an air barrier composition to a portion of the innerliner layer of the cured tire to thereby form an air barrier layer on the cured tire, wherein the air barrier layer is formed only between each first longitudinal edge of the pair of reinforcing members, wherein the air barrier composition is a phase-separated polymeric system wherein an elastomeric component is phase separated from a thermoplastic component, wherein the air barrier layer includes a permeability to oxygen (P(O2)) of less than 250 cc·mm/m2·day·atm as measured in accordance with ASTM method F1927-14.
