Problems solved by technology

However, nano zinc oxide is easy to agglomerate, especially after a period of storage, which leads to poor dispersion in the rubber compound.
[0004] In addition, ordinary zinc oxide is a necessary auxiliary agent for the vulcanization system in rubber products. Its filling is relatively high, generally about 5 parts. Detrimental to life and energy consumption

Abstract

The invention relates to a preparation method of a vulcanizing activator taking a metal organic framework material as a carrier. The preparation method comprises the following steps: S1, enabling an alkaline solution to react with an organic carboxylate ligand to prepare a metal organic framework material precursor solution; S2, enabling a zinc salt solution to react with a metal organic frameworkmaterial precursor to generate a zinc metal organic framework compound; S3, washing and filtering the zinc metal organic framework material; S4, introducing a carrier: preparing a zinc metal organicframework compound filter cake into suspension, adding a calcium hydroxide solution, stirring the solution for certain time till calcium hydroxide and the zinc metal organic framework compound react with each other completely, generating a calcium-based organic framework compound and zinc hydroxide, and adsorbing the generated zinc hydroxide by the calcium-based organic framework compound, so as to form a supported zinc hydroxide@ calcium metal organic framework material; S5, filtering and drying a finished product, so as to prepare a micro-nano low-zinc vulcanizing activator. The preparationmethod has the advantages of being simple, convenient, low in energy consumption, easy to control, and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of vulcanization activators, in particular to a method for preparing a vulcanization activator with a metal organic framework material as a carrier. Background technique [0002] Metal-organic framework materials are a coordination polymer that has developed rapidly in the past ten years. It has a three-dimensional pore structure. Generally, metal ions are used as connection points, and organic ligands are supported to form a 3D extension of space. Metal ions and multi-dentate organic ligands Self-assembled into a class of organic-inorganic hybrid porous materials, it has the characteristics of large specific surface area, high porosity, and adjustable structure and properties, making it another important new type of material after zeolites and carbon nanotubes. Porous functional materials are widely used in catalysis, energy storage and separation. The role of metal cations in MOFs is to provide the backbo...
