| titleOfInvention | A kind of high tear strength addition type liquid fluorosilicone rubber and preparation method thereof |
| abstract | The invention relates to a high tear strength addition type liquid fluorosilicone rubber and a preparation method thereof. The rubber is formed by mixing two components, A and B, and the A component includes: 40-60 parts of fluorosilicone base rubber I, 37 parts ~54 parts of fluorosilicon base rubber II, 3 to 6 parts of high tear resistance additives, 25 to 30 parts of fumed silica, 1 to 2 parts of platinum catalyst, 1 to 3 parts of heat-resistant additives; component B includes: 40 to 60 parts of fluorosilicone base rubber I, 37 to 54 parts of fluorosilicon base rubber II, 3 to 6 parts of high tear resistance additive, 25 to 30 parts of fumed silica, 6 to 12 parts of fluorosilicon crosslinking agent, 0.1 to 0.5 parts 1 part inhibitor, 1 to 3 parts heat resistant additive. The invention prepares high tear-resistant additives for addition type fluorosilicone rubber, and then makes the three synergistic effects in the form of high and low-viscosity base rubber compounding, and then there is a two-dimension between the side group hydrogen and the main chain silicon-oxygen chain link. The polyfluorosiloxane with the methylsiloxane link structure is used as a crosslinking agent to form crosslinking points with different densities synchronously vulcanized, which greatly improves the tear resistance. |
