Abstract

The invention discloses an erbium-based multi-ligand vulcanization accelerator for rubber and a preparation method thereof. A rare earth element in the synthesis is erbium which contains 4 ligands, wherein a ligand 1 and a ligand 2 are accelerant groups with a good vulcanization accelerating effect; a ligand 3 is citric acid which can form strong coordination with the rare earth element; a ligand 4 is triethanolamine which can improve the solubility of the accelerator in rubber materials. The preparation method is simple, convenient and feasible, does not need inert gas shielding, is moderate in conditions of the preparation process, and generates no harmful gas. The multi-ligand rare earth vulcanization accelerator has good solubility in rubber,is long in vulcanization and scorching time and excellent in flatness of vulcanization curve, and is non-toxic, odorless and pollution-free. The accelerator can be applied to high performance tire and other rubber products instead of the conventional frequently-used blending system of zinc oxide, stearic acid and an accelerator.

Description

technical field

[0001] The invention relates to a synthesis method of an erbium-based multi-ligand vulcanization accelerator and research on its vulcanization acceleration effect. This accelerator does not need zinc oxide and stearic acid as an activator, and has the advantages of saving the feeding process, clean and pollution-free, good vulcanization flatness, and easy to uniformly disperse in rubber. The rubber composite material prepared by using this accelerator has the advantages of Good performance uniformity. Background technique

[0002] The vulcanization system of rubber is a complete vulcanization system composed of accelerators, activators, and vulcanizing agents. Among them, the accelerator is a chemical substance that can shorten the vulcanization time, lower the vulcanization temperature, reduce the amount of vulcanizing agent, and improve and improve the physical and mechanical properties and chemical stability of the vulcanized rubber. Just because acceler...
