| 阻燃输送带覆盖胶配方 Formula of cover adhesive for flame retardant conveyer belt 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。 The adhesive for flame retardant conveyor belt should have high mechanical strength, wear resistance, flame resistance and electrostatic conductivity. ①生胶的选择 The selection of the raw glue 生胶的选择主要从覆盖胶的加工工艺性能和物理机械性能这两方面性能要求来考虑。通过添加阻燃剂和炭黑达到难燃和导静电性能要求。 The choice of raw rubber is mainly considered from two aspects: the processing performance and the physical and mechanical properties of the covering rubber. By adding flame retardant and carbon black to achieve the requirements of flame retardant and electrostatic conductivity. ②阻燃体系的选择 Selection of flame retardant system 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。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。氯化石蜡、十溴二苯醚、氢氧化铝、硼酸锌体系虽能有效地抑制无焰燃烧，但对阻止有焰燃烧效果不够显著。因此尼龙分层难燃输送带覆盖胶的难燃体系选择氯化石蜡、十溴二苯醚、三氧化二锑、氢氧化铝和硼酸锌并用体系。 The selection of flammable system is very important for flammable and electrostatic products. Carbon black is a good reinforcing agent in rubber products and can effectively reduce the surface resistance of products. But the use of Tan Hei often produces flameless combustion (Tan Hei), which will have a very negative effect on flameless combustion. Therefore, how to effectively suppress flameless combustion is an important issue in the formulation design for the refractory and electrostatic rubber products using carbon black as a reinforcing agent. The results show that chlorinated paraffin and three oxidation of two antimony can effectively prevent flame combustion but at the same time encourage flameless combustion. Although chlorinated paraffin, 10 bromo diphenyl ether, aluminum hydroxide and zinc borate system can effectively suppress flameless combustion, it is not effective enough to prevent flaming combustion. Therefore, the refractory system of nylon lamination refractory conveyor belt covering adhesive is selected as the system of chlorinated paraffin, dimethyl diphenyl ether, three oxidation two antimony, aluminum hydroxide and zinc borate. |
