Embodiment 1

[0053] A kind of comprehensive accelerator masterbatch, its preparation method comprises the following steps:

[0054] ①, Premix:

[0055] Put 9.5kg of EPDM 4045M and 2kg of EVA resin into the internal mixer for mixing, discharge the glue at 120°C, and harvest the masterbatch;

[0056] ②, Mixing: Put the masterbatch harvested in step ① and accelerator ZBEC 17.5kg, accelerator TBTD 5kg, accelerator CLD 5kg, stearic acid 0.75kg, fatty acid zinc 1.25kg and trehalose 0.5kg into the internal mixer Mixing, debinding at 50-65°C, specifically at 60°C in this example, to obtain the compounded material;

[0057] 3. Open refining: send the mixed material obtained in step 2 into the open mill, adjust the roll distance of the open mill to be 1 mm, perform thin pass operation 2 times, and obtain the film;

[0058] ④, granulation: send the film prepared in step ③ into the granulator for cutting and granulation, turn on the blower to dry, and use a vibrating screen to promote the separation...

Abstract

The invention relates to the technical field of rubber, in particular to comprehensive accelerator masterbatch, a preparation method thereof and a vulcanized rubber product. The comprehensive accelerant masterbatch is prepared from the following components in parts by weight: 35 to 45 parts of an accelerant ZBEC, 10 to 20 parts of an accelerant TBTD, 10 to 20 parts of an accelerant CLD, 23 to 27 parts of a rubber matrix, 1.5 to 2.5 parts of stearic acid, 2.5 to 3.5 parts of fatty acid salt and 1 to 3 parts of trehalose. The accelerant ZBEC, the accelerant TBTD and the accelerant CLD are compounded and then added into the rubber, the ingredient adding procedure is simplified, vulcanization characteristic parameters can be easily adjusted to generate a better rubber vulcanization effect, the comprehensive accelerant masterbatch has the characteristics of high efficiency, low odor, environmental protection and low toxicity, and the finally obtained vulcanized rubber product has better quality.

Description

technical field [0001] The application relates to the field of rubber technology, more specifically, it relates to a comprehensive accelerator masterbatch, its preparation method and vulcanized rubber products. Background technique [0002] Vulcanization accelerators are referred to as accelerators for short. Adding a small amount of accelerators into the rubber compound can greatly promote the reaction between rubber and vulcanizing agent (crosslinking agent), speed up the vulcanization reaction speed, shorten the vulcanization time, and reduce the vulcanization reaction temperature. , Improve or improve the mechanical properties of rubber. As people pay more and more attention to environmental hazards, various industries have stricter requirements on the odor, VOC and toxic and harmful substances of vulcanized rubber products. Among them, the odor of vulcanized rubber products mainly comes from accelerators. [0003] At present, there are mainly two types of accelerators ...
