Scope of application:
Ol-7 has a specific sulfur chain distribution, which improves the processing defects of tethiosilane applied in the silica black-rubber system in the past, improves the productivity of rubber processing industry, and has the potential to replace tethiosilane. 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 mixture system, reducing the rheological property of the system, and seriously leading to the decline of processing performance. But mixing temperature is too low, will cause the silanol groups on the surface of the silica and silane coupling agent was not completely, the reinforcing effect is not enough, also the dispersion of white carbon black in rubber is not good, and the surface of the silica silanol groups react with silane coupling agent to produce ethanol could not be completely evaporated, the rest of the ethanol in the extrusion process to form bubbles. Therefore, in the past, when silane coupling agents were used to strengthen silica, they had to be mixed in several steps at 150 ° C, which inevitably reduced productivity. The appearance of dithiosilane coupling agent completely avoids the above deficiencies. Its specific sulfur chain distribution characteristics ensure the stability of the product at a certain high temperature, avoid the formation of free sulfur from polythiosilane desulfurization in the process of high temperature mixing; This ensures that the silane coupling agent and silica can fully react at temperatures higher than 150 ° C and achieve uniform dispersion in the rubber at the same time without affecting the processing performance. In this way, the production efficiency of the processing process is greatly improved, and the rubber products have excellent properties such as low heat generation and wear resistance. The excellent physical and chemical properties and processing properties of the product not only improve the physical properties of rubber products, but also reduce the production cost of the rubber products.
