Embodiment Construction

[0127] This tire 1 comprises a crown 2 reinforced by a crown reinforcement or belt 6 , two sidewalls 3 and two beads 4 , each of these beads 4 reinforced by a bead wire 5 . The crown 2 is covered by the tread, which is shown in the figure 1 not shown in A carcass reinforcement 7 is wound around two bead wires 5 in each bead 4 , the turn-up 8 of this reinforcement 7 being arranged for example towards the outside of the tire 1 shown here fitted to its rim 9 on. The carcass reinforcement 7 is composed, in a manner known per se, of at least one ply reinforced by "radial" cords (for example made of metal), ie these cords are arranged almost parallel to each other and extend from One bead extends from the other so as to be formed at 80 from the circumferential mid-plane (the plane perpendicular to the axis of rotation of the tire, situated at an intermediate distance from the two beads 4 and passing through the center of the crown reinforcement 6 ). ° and 90°.

Abstract

The present invention relates to a rubber composition comprising at least one phenol-aldehyde resin obtained from at least one aromatic polyphenol and at least one aromatic polyaldehyde, said at least one aromatic polyaldehyde The phenol comprises at least one aromatic ring having at least two hydroxyl functional groups in meta positions relative to each other, the two ortho positions of at least one of the hydroxyl functional groups being unsubstituted; the at least one aromatic ring Group polyaldehydes selected from 1,3-phthalaldehyde, 1,4-phthalaldehyde and mixtures of said compounds, said rubber composition having a non-destructive property measured at 10% elongation according to ASTM standard D412 of 1998. Nominal secant modulus below 25 MPa.

Description

technical field [0001] The present invention relates to rubber compositions, methods for preparing the compositions, rubber compounds and tires. Background technique [0002] It is known in some tire components to use rubber compositions which have a higher stiffness during small strains of the tire. Small strain resistance is one of the properties a tire must have in order to respond to the stresses it is subjected to. Higher stiffness is intended to mean that the rubber composition has a nominal secant modulus at 10% elongation of greater than or equal to 25 MPa, preferably greater than or equal to 35 MPa, and more preferably strictly greater than 39 MPa. [0003] High stiffness can be obtained by incorporating certain reinforcing resins (as disclosed in WO 02 / 10269) into the composition. [0004] Typically, increases in stiffness are obtained by incorporating reinforcing resins based on methylene acceptor / donor systems. The terms "methylene acceptor" and "methylene don...
