Abstract

The invention discloses a multifunctional rubber modifier for an all-steel radial tire. The molecule of the rubber modifier which is an in-situ grafted modified borate molecule of which the central atom is a boron element; and the molecular configuration is a three-arm telechelic structure and is in an amphiphilic nonionic configuration. The multifunctional rubber modifier has functions of internal and external lubrication and interfacial activation, can reduce the Mooney viscosity of mixed rubber, and improves the abrasive resistance, flexibility and ageing and fatigue resistance of vulcanized rubber. The multifunctional rubber modifier also can improve the cost performance of rubber products so as to reduce the product cost and improve the performance. The provided preparation method issimple in technology, can achieve higher efficiency and reduce the environmental pollution, is mild in reaction conditions, easy and convenient to operate, ensures that the products are easy to separate, and has large-scale application prospects.

Description

technical field

[0001] The invention relates to a rubber modifier, in particular to a multifunctional rubber modifier for all-steel radial tires and a preparation process thereof. Background technique

[0002] Researchers at the University of Akron in the United States found that carbon black has been used to reinforce rubber for nearly a hundred years. Carbon black has been used as a rubber reinforcing agent until now. Although people have been studying it continuously in order to improve its reinforcing effect and other properties, Especially to improve the wear resistance of tire tread rubber, but there is still no major progress. During the processing of many polymer materials such as rubber and plastics, multiple material systems with very different surface energies are involved. In this way, in the process of mixing, the compatibility of various materials is not good, which affects the dispersion performance, and then It will affect the mechanical properties of materi...
