The application discloses a rubber nanocomposite containing modified MXene and a preparation method thereof, and belongs to the technical field of tire rubber materials. The technical scheme comprises natural rubber and modified MXene. The modified MXene is obtained by stirring and ultrasonically mixing MXene dispersion liquid, cellulose nanowire (CNF) dispersion liquid and unsaturated alkyl amine and fully reacting. The application is applied to tire rubber materials, solves the problems that existing MXene is prone to aggregation and has limited interfacial bonding force with a rubber matrix, can greatly enhance the interfacial interaction between the MXene and the rubber matrix, improve the compatibility of the MXene and the rubber matrix, and improve the mechanical properties of the rubber nanocomposite.

This invention relates to the field of rubber preparation, specifically to a method for preparing a lignin / rubber nanocomposite masterbatch and its product. The invention involves epoxidizing rubber latex to obtain epoxidized rubber latex, then dynamically mixing the obtained epoxidized rubber latex with lignin slurry. At high speed, the lignin adsorbs onto the epoxidized rubber latex particles, resulting in self-flocculation to obtain the lignin / rubber nanocomposite masterbatch. The lignin exhibits good dispersibility in the lignin / rubber nanocomposite masterbatch, significantly reducing stress defects and improving mechanical properties.

The present application relates to a kind of rubber materials, further, it is a kind of low rolling resistance rubber nanocomposite and its preparation method, application, the vulcanized rubber of preparation.The present application is modified by rough carbon point to white carbon black and compound, after mixing, obtain a kind of low rolling resistance rubber nanocomposite;The tensile, tear performance of the low rolling resistance rubber nanocomposite is improved.Vulcanized rubber is obtained by using the low rolling resistance rubber nanocomposite vulcanization, the rolling resistance coefficient of the vulcanized rubber as tread rubber is small, the tire product prepared by using the vulcanized rubber has lower rolling resistance, it has greater oil-saving advantage when being used in green tire.

The invention relates to the technical field of rubber nano composite materials, and discloses a high-cutting-resistant wear-resistant high-compatibility hydrogenated nitrile rubber / natural rubber composite material and a preparation method thereof. In the presence of an initiator and a solvent, itaconic anhydride and epoxidized isoprene rubber are subjected to a grafting reaction, and the itaconic anhydride grafted epoxidized isoprene rubber is obtained. After itaconic anhydride grafted epoxidized isoprene rubber is introduced into a natural rubber (NR) / hydrogenated butadiene-acrylonitrile rubber (HNBR) composite material to serve as a compatilizer, a polar anhydride group in the compatilizer and a nitrile group in hydrogenated butadiene-acrylonitrile rubber are subjected to hydrogen bond or dipole-dipole interaction, and interface chemical bonding is enhanced; meanwhile, a non-polar main chain in the compatilizer is compatible with the natural rubber, bridging is formed on a natural rubber / hydrogenated nitrile rubber interface, the compatibility between the non-polar NR and the polar HNBR is effectively improved, the synergistic effect of the non-polar NR and the polar HNBR on the microstructure is achieved, and the wear resistance and the cutting resistance of the composite material are improved.
