Abstract
Description
technical field
[0001] The invention relates to a rubber additive, in particular to a pre-dispersed masterbatch of an environmental protection comprehensive accelerator for automobile sealing strips and a preparation method thereof. Background technique
[0002] In order to improve the vulcanization efficiency and good physical properties of the rubber compound in the production of automotive sealing strips, it is generally necessary to use an accelerator system with high reactivity and high dosage. The commonly used accelerator system is based on derivatives of thiuram and dithiocarbamate. However, such products can form carcinogenic nitrosamines during the vulcanization process, and increase the possibility of scorching and frosting of the rubber, and the automobile sealing strips made of them have a strong smell.
[0003] At the same time, this traditional powder accelerator produces a lot of dust during the mixing and vulcanization process and is difficult to uniformly d...
