Abstract

The invention relates to the application field of industries such as tires and rubber products, in particular to a rubber composition using a low-zinc metal-organic framework material as an active agent, the rubber composition comprises pure rubber, white carbon black, carbon black, a rubber active agent and a silane coupling agent, the rubber active agent adopts a low-zinc MOFs material to replace zinc oxide, and the silane coupling agent is a silane coupling agent. The low-zinc MOFs material is a low-zinc metal-organic framework material with organic carboxylate as a core and nano-zinc oxide as a shell, the zinc content of the low-zinc MOFs material is lower than 50%, and the white carbon black, the rubber activator and the silane coupling agent are added into pure rubber together for mixing. According to the method, the dispersity of the white carbon black is improved, the silanization reaction degree is improved, meanwhile, flocculation of the white carbon black can be reduced, and the scorching time is prolonged. Furthermore, the zinc content in the rubber composition is also reduced, and a low-zinc formula is developed, so that the pollution of the tire rubber composition to the environment is reduced.

Description

technical field [0001] The invention relates to the application fields of industries such as tires and rubber products, in particular to a rubber composition using a low-zinc metal-organic framework material as an active agent. Background technique [0002] In the tire industry, activators, like vulcanizing agents and accelerators, are one of the most critical additives in the tire rubber vulcanization system. Zinc oxide has been used in rubber activators for tires for more than 100 years, but it has not been replaced by a more economical and suitable new vulcanization activator. With the continuous and rapid development of the automobile and tire rubber processing industry, the non-renewable use characteristics of zinc oxide as a rubber active agent, and the gradual reduction of zinc ore resources, one of the non-ferrous heavy metals, make it possible to study new active agents in tire rubber compositions. The application in the field becomes more and more important. [0...
