A multifunctional material produced by in-situ recombination, weak bond suspension, active coating and particle size expansion technology, which comprises a plurality of functional groups, such as nano short fibers, nano vapor phase silicon oxides, and non-metal complexes. Performance characteristics 1.LG-1520 has the effect of improving the wear resistance of the formulation and reducing the porosity of the part, which can extend the service life of the tire. 2.LG-1520 has the function of reducing the heat generation of vulcanized rubber by 5%-10%, so that the anti-aging performance of the rubber compound is greatly improved. 3. LG-1520 has excellent processability, including interfacial active components, which can reduce the energy difference between the interfaces of various materials in the formulation. It is easy to eat in the rubber mixing process, and the tire tread is pressed out and filmed. When pressed out, the dimensional stability is good, and the surface is fresh, smooth and elegant.
