- the invention relates to a compound, a rubber compound containing the compound, a vehicle tire which has the rubber compound in at least one component, a method for producing the compound and the use of the compound as an aging inhibitor and/or antiozonant and/or dye.
- Natural rubber, synthetic polymers such as IR, BR, SSBR, ESBR, etc.
- natural and synthetic oils, greases and lubricants are subject to oxidation reactions when stored for a long period of time and especially in the target application, which often takes place at higher temperatures, which can have adverse effects affect the original desired properties.
- the polymer chains are shortened to the point of liquefying the material, or the material is subsequently hardened.
- Anti-aging agents therefore make a significant contribution to the longevity of vehicle tires and other technical rubber items.
- antioxidants are aromatic amines, such as 6-PPD (N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine),
- IPPD N-isopropyl-N'-phenyl-p-phenylenediamine
- SPPD N-(1-phenylethyl)-N'-phenyl-p-phenylenediamine
- Anti-aging agents that react with ozone in particular and intercept it are also referred to as “ozone protection agents” or “antiozonants”.
- the invention is based on the object of providing a novel compound which can be used in particular as an anti-aging agent in vehicle tires or other technical rubber articles with a lower risk potential and sufficient solubility in the respective matrix, for example and in particular in the polymer. This is intended to ensure continued optimal protection against oxygen and ozone while reducing the health hazards and to prevent the tendency to bloom.
- the object is achieved by the compound according to the invention as claimed in claim 1, the rubber mixture according to the invention containing the compound and the vehicle tire according to the invention which has the rubber mixture according to the invention in at least one component.
- the object is achieved through the use of the compound as an anti-aging agent and/or an anti-ozone agent.
