Clay minerals as silicone rubber reinforcing agent applied research and development

Clay minerals as a rubber reinforcing agent applications have been reported, but the clay minerals as silicone rubber reinforcing agent is still rare. Silicone rubber in the aerospace, aviation, industrial electronics and other fields have a wide range of applications. Traditional silicon rubber reinforcing agent carbon black is white gas, as a result of high prices (3 to 50,000 yuan / t) so that the silicone rubber products cost much more, if through some physical and chemical processing, using clay minerals (300 ~ 500 yuan / t) for the silicone rubber reinforcement agent, not only can greatly reduce costs, but also to increase the added value of clay minerals for the use of clay minerals to provide a new way. Optional filler Shenyang A-380 gas producing white carbon black (A1), precipitation of white carbon black production in Jiangxi Province (A2) and after separation, purification, pure hours, after the modified ultra-fine clay minerals in the southern Fujian (A3) and the central part of clay Minerals (A4). If the formula Table 1. Curing temperature of 130 ℃, the pressure 14MPa, time 10min.
