Product introduction and application
The product has a specific sulfur chain distribution, and its appearance improves the processing defects of tetrathionosilane used in white carbon black-rubber system in the past, improves the productivity of rubber processing industry, and has the potential to replace tetrathionosilane. In the past, polysulfide compounds were easily desulphurized to form free sulfur in the high temperature mixing process higher than 150ºC. The appearance of free sulfur made the high temperature mixing process produce vulcanization effect, resulting in gelation of the rubber mixing system, reducing the rheology of the system, and seriously leading to the decline of processing performance. However, if the mixing temperature is too low, it will lead to incomplete reaction between the silyl alcohol group and the silane coupling agent on the surface of white carbon black, resulting in insufficient reinforcement effect, and the dispersion of white carbon black in rubber is not good, and the silyl alcohol group on the surface of white carbon black reacts with the silane coupling agent to produce ethanol can not be completely evaporated, and the remaining ethanol will form bubbles during the extrusion process. Therefore, in the past, when the silane coupling agent was used to reinforce white carbon black, it had to be mixed in multiple steps at 150 ° C, which inevitably reduced productivity. The appearance of disulfide silane coupling agent completely avoids the above deficiencies. The specific distribution characteristics of the sulfur chain ensure the high temperature stability of the product, and avoid the formation of free sulfur in the process of high temperature mixing. It ensures that the silane coupling agent and white carbon black can fully react at temperatures above 150 ° C, and at the same time complete uniform dispersion in the rubber without affecting the processing performance. In this way, the production efficiency of the processing process is greatly improved, and the rubber product has excellent low heat generation and wear resistance properties. The excellent physical and chemical properties and processing properties of the product not only improve the physical properties of the rubber product, but also reduce the production cost of the rubber product.
