Abstract

The present application relates to the field of new tire materials, in particular to a high-stiffness, low-viscosity tire compound, a preparation method thereof, and a semi-steel radial tire using the compound. A high-stiffness, low-viscosity tire compounded rubber, based on 100 parts by mass of the rubber component, the rubber component of the compounded rubber comprising synthetic trans-1,4-polyisoprene (TPI) and / or Or natural eucommia gum (EUG) 1.0-30.0 parts, and adding 0.1-2.0 parts of hydrazide-type material modifiers to prepare, the mixed rubber of the application can significantly improve the stiffness of the rubber compound and improve the viscosity of the rubber compound, but it is not easy to Causes the cap to bloom, which is especially suitable for the manufacture of semi-finished tire caps with high stiffness, low viscosity and low heat generation.

Description

technical field [0001] The present application relates to the field of new tire materials, in particular to a high-stiffness, low-viscosity tire compound, a preparation method thereof, and a semi-steel radial tire using the compound, which can significantly improve the stiffness and stiffness of the compound. Viscosity, reducing tire rolling resistance, especially suitable for improving the stiffness and viscosity of tire semi-finished products during processing. Background technique [0002] With the rapid development of tires and the continuous improvement of tire processing and service performance, the stiffness and viscosity of rubber compounds used in tire semi-finished products have attracted more and more attention from tire manufacturers. [0003] Natural rubber or synthetic rubber and compounding agent are mixed in a certain proportion by a rubber mixer in an uncrosslinked state, which is called mixed rubber. The stiffness of the rubber compound is expressed by sti...
