Description
Technical Field
The present invention relates to a rubber composition and a vulcanized rubber obtained by uniformly mixing and vulcanizing the rubber composition.
Background
In recent years, with the development of the automobile industry and the rising of the oil price, people pay more attention to the safety and energy saving of automobiles, and tires having high wet skid resistance and low rolling resistance are required. However, it is often difficult to achieve both improved wet skid resistance and reduced rolling resistance. Therefore, according to different use requirements, an optimum balance between high wet skid resistance and low rolling resistance needs to be found.
For producing a tire with low rolling resistance, the anion-polymerized solution-polymerized butylbenzene has more remarkable advantages than emulsion-polymerized butylbenzene because the anion solution polymerization can effectively adjust the content and the glass transition temperature of a conjugated diene structural unit with a double bond in a side chain. This advantage is advantageous for balancing the relationship between the wet skid resistance and the rolling resistance of the tire. Further, studies have shown that the addition of a silane coupling agent during the kneading of a rubber composition can promote the dispersion of a filler in the raw rubber to some extent and improve the relationship between the wet skid resistance and the rolling resistance of the rubber to some extent, but the reactivity of the silane coupling agent with the raw rubber and carbon black is lowered by the influence of other additives during the kneading of the rubber composition. Further, addition of the silane coupling agent during the kneading of the rubber composition also causes an unpleasant odor. It is disclosed in EP447066 that a silane having a structure represented by formula (1) can be used as a modifier to improve wet skid resistance and reduce rolling resistance of styrene-butadiene rubber:
USi(OR')jR''4-i-jthe compound of the formula (1),
wherein U is halogen, R 'and R' are C1-C20J is an integer from 1 to 4, i is an integer from 0 to 2, and the sum of i and j is from 2 to 4. The silane having the structure represented by formula (1) can be bonded to a polymer molecular chain by reacting a halogen with a catalyst residue at the end of the polymer molecular chain, however, usually, one polymer molecular chain can be bonded with only one silane molecule, and only a small influence is exerted on the interaction between the polymer molecular chains, and the wet skid resistance of rubber cannot be effectively improved and the rolling resistance is reducedDynamic resistance.
Disclosure of Invention
The invention aims to overcome the defect that the relation between the wet skid resistance and the rolling resistance of rubber cannot be effectively improved by the conventional method, and provides a rubber composition which has high wet skid resistance and low rolling resistance and vulcanized rubber obtained by uniformly mixing and vulcanizing the rubber composition.
The invention provides a rubber composition, which contains olefin rubber, a vulcanizing agent, a vulcanization accelerator, a reinforcing agent and an activator, wherein the olefin rubber contains a modified olefin polymer, the molecular chain of the modified olefin polymer contains at least one monovinylarene structural unit and at least two conjugated diene structural units, the molecular chain of the modified olefin polymer also contains a silane coupling agent structural unit shown in a formula (I), and the number average molecular weight of the modified olefin polymer is 5-100 ten thousand;
wherein R is1-R4Is C1-C20A straight or branched hydrocarbon group or C containing a hetero atom1-C20The heteroatom is selected from one or more of halogen, oxygen, sulfur, silicon and phosphorus.
The invention also provides vulcanized rubber obtained by uniformly mixing and vulcanizing the rubber composition.
As described above, in the prior art, the silane coupling agent is generally added during the kneading of the rubber composition to improve the wet skid resistance of the rubber and to reduce the rolling resistance thereof, but in this case, the reactivity of the silane coupling agent with the raw rubber and the carbon black is reduced, and it is difficult to significantly improve the relationship between the wet skid resistance and the rolling resistance of the rubber and an unpleasant odor is generated. The present inventors have made intensive studies and, as a result, have found that by chemically bonding a silane coupling agent to an olefin polymer and using the resulting modified olefin polymer as a whole as a part or whole of a rubber-based rubber, it is possible to avoid the problem of a decrease in the reactivity of the silane coupling agent with raw rubber and carbon black caused during the mixing of a rubber composition, and to effectively balance the relationship between wet skid resistance and rolling resistance of a tire made of the rubber composition, and also to improve the unpleasant odor caused by the use of the silane coupling agent during the mixing of the rubber composition.
Additional features and advantages of the invention will be set forth in the detailed description which follows.
