Description
Technical field
The present invention relates to rubber materials, say further, relate to a kind of styrene-butadiene rubber(SBR) composition and method of making the same.
Background technology
Increasingly in short supply along with the increasingly stringent of reducing emission of carbon dioxide policies and regulations and petroleum resources, how reduce fuel oil consumption becomes the focus that automobile industry and user pay close attention to, and the rolling resistance that reduces tire is one of important measures that reduce vehicle fuel consume.
In reducing tyre stock (mainly being tread rubber) rolling resistance research, very thorny rolling resistance, wet and slippery performance, conflicting so-called " Magic triangle " problem of wear resisting property have been run into.Simply increase the tenderizer consumption, can improve the anti-slippery of tire, but its wear resistance reduces and rolling resistance increases.Improve the consumption of reinforced filling (carbon black or white carbon black), can reduce to a certain extent rolling resistance, but make reinforced filling in sizing material, be difficult to be uniformly dispersed, and anti-slippery is reduced.Strengthen the consumption of vulcanizing agent, namely improve cross-linking density, the same with the effect that increases the reinforced filling consumption, reduce rolling resistance and make simultaneously the anti-slippery variation.In order to realize the balance of three aspects: performance, except Design of Tire Structure is optimized, also sizing material (take tread rubber as main) prescription has been carried out research extensively and profoundly both at home and abroad.Synthesize on the one hand applicable rubber raw materials (such as solution polymerized butadiene styrene rubber SSBR, using trans-polyisoprene TPI, butadiene-isoprene-vinylbenzene integrated rubber SIBR, high-vinyl cis-1,4-polybutadiene rubber HVBR etc.), properties-correcting agent and the practical formulation of setting about on the other hand seeking to have better over-all properties.Some progress in formulating, have been obtained, more representationally be: solution polymerized butadiene styrene rubber (SSBR) etc. and carbon black and white carbon black and with or reciprocal (counter-rotating) carbon black system, the system characteristics are that main formula is substantially constant, just different on reinforced filling, easily in industrial realization; Its shortcoming is that machine utilization is large when needing to use more silane coupling agent and refining glue, and the wear resistance of cross-linked rubber is also undesirable.
Meanwhile, the researchist finds that crosslinked powdered rubber can reduce the rolling resistance of cross-linked rubber when prescription is suitable.(swelling index 4～5, particle diameter 60～450nm) rolling resistance of natural rubber (NR) formula system cross-linked rubber is reduced, and strength property are uninfluenced for the crosslinked suitable fourth of patent US6184296 use process surface modification and butylbenzene powdered rubber.In patent US6133364,1-chloro-4-methyl-benzene is grafted on the crosslinked butylbenzene powdered rubber surface, then use it in the NR formula system, the rolling resistance of cross-linked rubber is reduced, and anti-slippery improve.
Patent US6207757 has reached the effect that reduces NR formula system cross-linked rubber rolling resistance with the crosslinked butylbenzene powdered rubber of 1-chloro-4-methyl-benzene modification, has improved simultaneously hauling ability and the wearing quality of tire.
Patent US6242534 is used for the NR formula system in the lump to the crosslinked butylbenzene powdered rubber that contains carboxyl and amino, has not only reduced the rolling resistance of system cross-linked rubber, has improved anti-slippery, and has obviously improved stress at definite elongation.
Patent EP1431075 with butylbenzene powdered rubber and plasticized starch improve styrene-butadiene rubber(SBR) (SBR) and cis-1,4-polybutadiene rubber (BR) and with and the performance of white carbon black system, as a result wear resistance be improved, the rolling resistance reduction, the proportion of cross-linked rubber is also less.
Patent US6699935 makes modification butylbenzene formula system have low-rolling-resistance with the crosslinked butylbenzene powdered rubber of modification by copolymerization and has outstanding anti-slippery and wear resistance concurrently.
The crosslinked butylbenzene powdered rubber that above-mentioned patent documentation is mentioned all adopts Chemical Crosslinking Methods crosslinked, this method need to use the higher cross-linking monomer of price and energy consumption larger, and relates generally to white carbon black system and the modification butylbenzene formula system of natural rubber formulations system or styrene-butadiene rubber(SBR).
In sum, seek a kind of styrene-butadiene rubber(SBR) composition, energy consumption is lower when improving performance, is the present technical issues that need to address.
