Embodiment 1

[0066] With 20phr of natural rubber, 44phr of butadiene rubber, 36phr of solution-polymerized styrene-butadiene rubber, 50phr of glass fiber, 3phr of sulfur, 1phr of ZDTP, and 1.5phr of CBBS, first remove sulfur, The components other than ZDTP and CBBS are fully mixed in a tangential mixer, and then sulfur, ZDTP and CBBS are added and mixed evenly. Heated and melted and extruded, the above mixture was further mixed uniformly, and a tire sample was formed by a conventional method in the rubber industry.

Embodiment 2

[0078] With 20phr of natural rubber, 23phr of butadiene rubber, 36phr of styrene-butadiene rubber, 21phr of ethylene propylene rubber, 30phr of glass fiber, 10phr of sulfur and 5phr of TBSI, first of all other components except sulfur and TBSI in Mix thoroughly in a tangential mixer, then add sulfur and TBSI, and mix well. Heated and melted and extruded, the above mixture was further mixed uniformly, and a tire sample was formed by a conventional method in the rubber industry.

Embodiment 3

[0086] 20phr of natural rubber, 23phr of butadiene rubber, 36phr of styrene-butadiene rubber, 21phr of ethylene-propylene rubber, 80phr of glass fiber, 10phr of sulfur, 4.5phr of TBSI and 2phr of CBBS, first remove sulfur, TBSI, and CBBS Mix the other components well in a tangential mixer, then add sulfur, TBSI and CBBS, and mix well. Heated and melted and extruded, the above mixture was further mixed uniformly, and a tire sample was formed by a conventional method in the rubber industry.

Abstract

The invention provides a rubber composition. The rubber composition mainly comprises at least one type of polar or non-polar rubber, at least one type of fillers, at least one type vulcanizing agents, at least one type of accelerators, optional scotch retarders and optional aromatic substances. Each accelerator is a chemical compound with two or more X-Y single bonds, wherein the X selectively represents O and S elements, and the Y selectively represents N and P elements. The environment-friendly rubber composition and a tire (spare tire in particular) prepared from the rubber composition have the advantages that the rubber composition comprises the modified accelerators and the modified scotch retarders, accordingly, generation of organic volatile matters such as aniline, cyclohexylamine, tert-butylamine and imine with pungent odor can be reduced, and the problem of odor of existing tires can be solved; substances such as carbon black and zinc oxide with fine powder can be omitted, and accordingly dust hazards on operators in production procedures can be reduced; the rubber composition comprises the added aromatic substances, and accordingly fragrant smell of the tire further can be enhanced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a low-odor, environment-friendly rubber mixture and a tire prepared from the rubber mixture, especially a spare tire. Background technique [0002] Tire is one of the important parts of the car. It is in direct contact with the road surface. It is an important part of the car to bear gravity, transmit traction force, braking force, steering force and bear the reaction force of the road surface. It works with the car suspension to ease the impact of the car when it is driving, to ensure that the car has good ride comfort and ride comfort; to ensure good adhesion between the wheels and the road surface, and to improve the traction, braking and performance of the car. Passability; Bearing the weight of the car, the important role played by the tire on the car is more and more valued by people. [0003] Because the tires will wear out during use, if they are not replaced for a l...
