Provided is a seal member for rolling bearing, which includes a seal body, and a coating layer that contains an antiozonant and silicone oil, and is formed on a surface of the seal body. The seal member for rolling bearing can be produced by applying on a surface of the seal body, a coating composition containing 10 to 30% by weight of an antiozonant and 3 to 10% by weight of silicone oil, the antiozonant and the silicone oil being dispersed in a solvent.

A rubber composition having good resistance to ozonization properties, in particular without the need to use 6PPD. This rubber composition is suitable for use in rubber articles, including in particular vehicle tires, such as rubber pneumatic tires, solid tires and non-pneumatic tires, and also general rubber products exposed to continuous and intermittent dynamic operating conditions and requiring protection from ozonization, like belts, hoses, cables, automotive mountings and bushings. In the rubber composition, the anti-ozonant compound is a partially hydrogenated quinoline derivative having formula (I) and serves to protect the rubber composition from ozonization and the consequent damaging effects caused by ozonization on the rubber composition.

In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, the disclosure, in one aspect, relates to new polymeric antioxidant and / or antiozonant compounds and methods of making the same. The compounds perform in rubber compositions comparably to known antiozonants such as 6PPD. Also disclosed herein are rubber compositions including the disclosed compounds and tires and / or other rubber articles including the rubber compositions.

The present disclosure provides N-phenyl-1,2-dihydroquinolin-6-amines, N-phenyl-1,2,3,4-tetrahydroquinolin-6-amines, methods and processes for preparing N-phenyl-1,2-dihydroquinolin-6-amines, and methods and processes for preparing N-phenyl-1,2,3,4-tetrahydroquinolin-6-amines having antidegradant, e.g., antiozonant, antioxidant and / or antifatigue, properties. These compounds are useful additives for vulcanized rubber articles.

The utility model relates to the technical field of rubber additive processing, and discloses a rubber additive antiozonant mixing device which comprises a solid material mixing cylinder, and a material filtering mechanism is fixedly mounted in a cylinder opening of the solid material mixing cylinder; the material filtering mechanism comprises an annular filtering disc body, a through hole is formed in the center of the annular filtering disc body, and an annular material blocking flange is fixedly connected to the edge position of the through hole; the mixing device further comprises a solid material stirring mechanism, the solid material stirring mechanism comprises a material shaft rotationally connected into the solid material mixing cylinder, the upper end of the material shaft is fixedly connected with a plurality of flow striking plates, and the materials are filtered through the material filtering holes, enter the solid material mixing cylinder and are subjected to flow striking and dispersion through the flow striking plates. According to the structure, in the anti-ozone agent mixing process, the mixing effect is remarkably improved due to the fact that material liquid is uniformly dispersed.

This disclosure provides compounds and compositions having the properties of degradation inhibitors, such as anti-ozone agents, antioxidants, and / or anti-fatigue agents, which are useful additives for vulcanized rubber articles. In some embodiments, the composition comprises 2,2,4-trimethyl-N-phenyl-1,2-dihydroquinoline-6-amine. This disclosure provides compounds and compositions useful as degradation inhibitors, such as anti-ozone agents and / or antioxidants, and / or as additives in vulcanized rubber articles, lubricants, or flammable fuels.
