Abstract

The invention discloses a pre-dispersed masterbatch of a scorch-resistant comprehensive accelerator for rubber. The masterbatch comprises the following components in parts by weight: 8-15 parts of a rubber matrix, 50-60 parts of a thiazole accelerator, 10-20 parts of an anti-scorching agent, 9-12 parts of a softener, and 1-3 parts of a processing auxiliary agent. A preparation method comprises the following steps: (1) a mixing step: the thiazole accelerator, the anti-scorching agent, the processing auxiliary agent and the softener are added into a mixer according to a certain ratio, mixing is carried out for about 30 seconds, the rubber matrix is added, and mixing is carried out for 8-12 minutes at 50-65 DEG C; (2) a granulation step: after mixing of materials, the materials are sent into a granulating machine for granulation. The pre-dispersed masterbatch is used for preparing rubber compounds, and has the advantages of easy dispersion, non-pollution, good processability, etc.; and the masterbatch provides good scorch-resisting effects for rubber.

Description

technical field

[0001] The invention relates to a rubber auxiliary agent, in particular to a pre-dispersed masterbatch of an anti-scorch comprehensive accelerator for rubber and a preparation method thereof. Background technique

[0002] In recent years, the rubber product industry has been pursuing high-temperature rapid vulcanization in order to improve production efficiency; in order to achieve this purpose, it is necessary to use an overspeed accelerator, and the corresponding scorch time is relatively short, which makes the rubber easy to scorch and poor in operation safety; At the same time, after the vulcanization begins, the rubber compound of the ultra-speed accelerator loses its activity rapidly, and the breakage of the cross-linking bond cannot be replenished, which causes the vulcanization flat period to be shortened, and vulcanization reduction is easy to occur.
