Problems solved by technology

[0004] It is worth noting that ZBEC is in the form of white powder. If it is added directly during mixing, there will be problems of uneven dispersion and dust pollution during the rubber mixing process, and the feeding speed is slow and the mixing time is long, which will affect the rubber production efficiency and quality

Abstract

The invention discloses an environment-friendly accelerator ZBEC pre-dispersed master batch and a preparation method thereof. The environment-friendly accelerator ZEBC pre-dispersed master batch comprises, by weight, 69-72 parts of dibenzyldithiocarbamic acid, zinc salt, 14-20 parts of rubber matrix, 8-13 parts of industrial mineral oil and 2-5 parts of saturated fatty acid zinc salt. The preparation method of the environment-friendly accelerator ZBEC pre-dispersed master batch is simple and easy to operate; according to the preparation method, mixing time for subsequent procedures of preparing the master batch is reduced effectively, the accelerator ZBEC pre-dispersed master batch prepared by the method maintains original activity of ZBEC effectively and is free of caking at room temperature, is convenient to weigh and easy to blend for mixing and has good flow characteristic after being blended with rubber; feeding time is accelerated while dust flying is avoided and skin allergy to operators is avoided, and utilization rate of raw materials is high; the master batch disperses uniformly in rubber products after blending and mixing and thus production efficiency and quality of the rubber products are guaranteed. The environment-friendly accelerator ZBEC pre-dispersed master batch has great significance in promoting sustainable development of rubber manufacturing and has wide industrial prospect.

Description

technical field [0001] The invention relates to the technical field of rubber additives and their preparation, in particular to an environment-friendly accelerator ZBEC pre-dispersed masterbatch and a preparation method thereof. Background technique [0002] The vulcanization accelerator ZBEC (zinc dibenzyl dithiocarbamate) belongs to the super speed accelerator. The name of similar products at home and abroad is VulkacitZBEC (Bayer). ZBEC is a new type of environmentally friendly secondary aminothiocarbamate vulcanization accelerator. It will not produce carcinogenic nitrosamines during use. The vulcanization activity temperature is low and the operation is relatively safe. It is an excellent activity of thiazole accelerators. It can be used to replace PZ, EZ, ZDBC, TMTM, etc., and can be used as the main accelerator or secondary accelerator of natural rubber, styrene-butadiene rubber, butyl rubber, EPDM rubber, natural latex and synthetic latex. Of all the dithiocarbamat...
