| 阻燃输送带覆盖胶应同时具备机械强度高，耐磨耗，难燃且导静电特性。 对于难燃且导静电制品，难燃体系的选择非常重要。炭黑在橡胶制品中即是很好的补强剂又能有效地降低制品表面电阻。 Flame retardant conveyor belt cover adhesive should have high mechanical strength, wear resistance, flame retardant and static conductivity characteristics at the same time. The choice of flame retardant system is very important for non-flammable and electrostatic products. Carbon black is not only a good reinforcing agent in rubber products, but also can effectively reduce the surface resistance of products. 但是炭黑的使用往往使制品产生无焰燃烧（炭黑），对阻止制品无焰燃烧将产生极为不利的影响。因此，对于使用炭黑作补强剂的难燃且导静电的橡胶制品，如何有效地抑制无焰燃烧是配方设计中着重考虑的问题。结果表明，氯化石蜡和三氧化二锑并用能有效地阻止有焰燃烧，但同时助长了无焰燃烧。 However, the use of carbon black often makes products produce flameless combustion (carbon black), which will have a very negative impact on preventing products from flameless combustion. Therefore, how to effectively suppress flameless combustion is a key issue in formulation design for flame retardant and static conductive rubber products using carbon black as reinforcing agent. The results show that the combination of chlorinated paraffin and antimony trioxide can effectively prevent flameless combustion, but at the same time promote flameless combustion. |
