Definitions
- Rubber composition comprising a reinforcing filler with a low specific surface area
- the present invention relates to a rubber composition comprising predominantly an isoprene elastomer and a tire comprising this composition.
- Document FR 2 981 298 discloses a tire comprising a layer of rubber material disposed between the ends of the two working crown plies, based on a predominantly isoprene elastomeric matrix and a reinforcing filler consisting of either surface carbon black specific BET greater than 60 m 2 / g, or carbon black BET surface area greater than 60 m 2 / g, or a white filler silica and / or alumina, this layer having a modulus of elasticity under voltage at 10% elongation less than 8 MPa and a maximum value of tan (delta) less than 0.10.
- the tires thus produced effectively improve performance, particularly in terms of endurance and rolling resistance.
- the invention relates to a rubber composition based on: an elastomeric matrix comprising at least 90 phr of at least one isoprene elastomer;
- a reinforcing filler comprising predominantly at least one carbon black, called black NC, in the context of the present invention, having a BET specific surface area at most equal to 30 m 2 / g and a dye oil absorption index; compressed samples (COAN) of not less than 60 ml / 100 g;
- composition not comprising, or comprising, at most 10 phr of carbon black having a BET specific surface area greater than 30 m 2 / g and COAN greater than 40 ml / 100 g, and not comprising, or comprising at most 10 phr of silica.
- part by weight per hundred parts by weight of elastomer (or phr) is meant for the purposes of the present invention, the part, in mass per hundred parts by mass of elastomer or rubber, the two terms being synonymous.
- any range of values designated by the expression "between a and b" represents the range of values from more than a to less than b (i.e. terminals a and b excluded) while any range of values designated by the term “from a to b” means the range from a to b (i.e., including the strict limits a and b).
- the interval represented by the expression "between a and b" is also designated and preferentially.
- a majority compound in the sense of the present invention, it is understood that this compound is predominant among the compounds of the same type in the composition, that is to say that it is the one which represents the largest amount by mass among the compounds of the same type.
- a majority polymer is the polymer representing the largest mass relative to the total mass of the polymers in the composition.
- a so-called majority charge is that representing the largest mass among the charges of the composition.
- the majority polymer accounts for more than half of the mass of the polymers.
- the term “majority” means more than 50%, preferably more than 60%, 70%, 80%, 90%, and more preferably the "majority" compound represents 100%.
- composition based on is meant a composition comprising the mixture and / or the reaction product in situ of the various constituents used, some of these constituents being able to react and / or being intended to react with each other, less partially, during the various phases of manufacture of the composition; the composition can thus be in the fully or partially crosslinked state or in the non-crosslinked state.
- the circumferential direction of the tire is the direction corresponding to the periphery of the tire and defined by the rolling direction of the tire.
- the transverse or axial direction of the tire is parallel to the axis of rotation of the tire.
- the radial direction is a direction intersecting the axis of rotation of the tire and perpendicular to it.
- the axis of rotation of the tire is the axis around which it rotates under normal use.
- a radial or meridian plane is a plane that entrusts the axis of rotation of the tire.
- the circumferential median plane is a plane perpendicular to the axis of rotation of the tire and which divides the tire into two halves.
- the compounds comprising carbon mentioned in the description may be of fossil origin or biobased. In the latter case, they can be, partially or totally, derived from biomass or obtained from renewable raw materials derived from biomass. These include polymers, plasticizers, fillers, etc. Elastomers
- the rubber composition according to the invention is based on at least 90 phr of at least one isoprene elastomer.
- the composition according to the invention may contain a single isoprene elastomer or a mixture of one or more isoprenic elastomers with one or more other elastomers.
- composition according to the invention may also comprise any type of non-isoprene diene elastomer, or other than diene, such as, for example, olefinic or thermoplastic elastomers.
- iene elastomer or indistinctly rubber, whether natural or synthetic, must be understood in known manner an elastomer consisting at least in part (ie, a homopolymer or a copolymer) of monomeric diene units (monomers carrying two carbon-carbon double bonds, conjugated or not).
- diene elastomers can be classified into two categories: “essentially unsaturated” or “essentially saturated”.
- the term “essentially unsaturated” is generally understood to mean a diene elastomer derived at least in part from conjugated diene monomers, having a level of units or units of diene origin (conjugated dienes) which is greater than 15% (mol%);
- diene elastomers such as butyl rubbers or copolymers of dienes and alpha-olefins of the EPDM type do not fall within the above definition and may in particular be described as "essentially saturated” diene elastomers ( low or very low diene origin, always less than 15%).
- iene elastomer that may be used in the compositions according to the invention is particularly understood to mean:
- the other monomer may be ethylene, an olefin or a diene, conjugated or otherwise.
- Suitable conjugated dienes are conjugated dienes having from 4 to 12 carbon atoms, in particular 1,3-dienes, such as in particular 1,3-butadiene and isoprene.
- unconjugated dienes are suitable non-conjugated dienes having 6 to 12 carbon atoms, such as 1,4-hexadiene, ethylidene norbornene, dicyclopentadiene.
- Suitable olefins are vinylaromatic compounds having 8 to 20 carbon atoms and aliphatic ⁇ -monoolefins having 3 to 12 carbon atoms.
- vinylaromatic compounds are suitable for example styrene, ortho-, meta-, para-methylstyrene, the commercial mixture "vinyl-toluene", para-tert-butylstyrene.
- aliphatic ⁇ -monoolefins are particularly suitable aliphatic acetic oc-mono-olefins having from 3 to 18 carbon atoms.
- the diene elastomer is:
- the diene elastomer may be modified, that is to say coupled and / or starred or functionalized with a coupling agent and / or starring or functionalization.
- the diene elastomer may be coupled and / or starred, for example by means of a silicon or tin atom which bonds the elastomeric chains together.
- the diene elastomer may be simultaneously or alternatively functionalized and comprise at least one functional group.
- functional group is meant a group comprising at least one heteroatom selected from Si, N, S, O, P.
- Particularly as functional groups include those comprising at least one function such as: an alkoxysilane, silanol, a primary amine , secondary or tertiary, cyclic or not, a thiol, an epoxide.
- isoprene elastomer a homopolymer or copolymer of isoprene, in other words a diene elastomer selected from the group consisting of natural rubber (NR) which can be plasticized or peptized, synthetic polyisoprenes (IR ), the various isoprene copolymers, in particular the copolymers of isoprene-styrene (SIR), isoprene-butadiene (BIR) or isoprene-butadiene-styrene (SBIR), and mixtures of these elastomers.
- NR natural rubber
- IR synthetic polyisoprenes
