Abstract

The invention provides an oxidized grapheme/carbon black rubber nanocomposite and preparation method thereof, which belongs to the field of rubber nanocomposite technology. The nanocomposite comprises the following basic compositions by mass: 100 parts of diene series rubber matrix, 0.5-5 parts of oxidized grapheme, 30-70 parts of hard carbon black of average particle size 11-30nm, 1-10 parts of plasticizer, 6-10 parts of activator, 0.5-4 parts of anti-aging agent, 1-4 parts of sulfuration promoter and 1-6 parts of insoluble sulphur; oxidized grapheme modifier. The oxidized grapheme powder is dispersed in deionized water for ultrasound, and a natural rubber emulsion is added, and masterbatch after flocculation, washing and drying is mixed uniformly with other additives, after sulfuration, the product is obtained. The oxidized grapheme/carbon black rubber nanocomposite has the advantages of excellent processing performance and obviously reduced dynamic themogenesis, thereby improving the usage life of tyre.

Description

technical field [0001] The invention relates to a graphene oxide / carbon black rubber nanocomposite material for automobile tires and a preparation method thereof. A very small amount of graphene oxide is used for in-situ modification and combined with hard carbon black to obtain a rubber composite material, which is applied to automobiles The tire apex rubber can obviously improve the hardness and modulus of the apex rubber, reduce dynamic heat generation, and improve the service life of tires, belonging to the technical field of rubber nanocomposite materials. Background technique [0002] The areas with the greatest stress of radial tires are the tire shoulder and bead area, especially when the overload is serious, the bead not only bears internal pressure stress, braking torque, sideslip and centrifugal force, and rim interference force, but also due to the carcass curtain The lines are arranged radially, the number of cord layers is small, and the carcass is soft, so tha...
