摘要
为探讨无机超细粉在橡胶工业中的应用效果,在丁苯橡胶中进行了填充实验并研究采用超细粉替代垫带胶配方中的炭黑的可行性。实验发现,加入无机超细粉的丁苯橡胶的硬度、拉伸强度、撕裂强度与加入炭黑的相比均比较小,只有扯断伸长率相对比较大,说明无机超细粉只起填充作用;将超细粉用在垫带胶中,当原有的40份炭黑N330用20份的无机超细粉替代时可以满足垫带胶的性能要求,即无机超细粉可以部分替代炭黑N330用于垫带胶中,降低胶料的成本,增加效益,同时达到保护环境的目的。
Superfine inorganic powder with d95 45 μm is produced from high quality coal and a small amount of inorganic substance through a special process. In this study, the application of super- fine inorganic powder in rubber industry is investigated. It is firstly filled in styrene-butadiene rubber （SBR）, then is used in tire flap compound to research the potential of replacement of carbon black. The results showed that some properties （include hardness, tensile strength, tear strength）is relatively lower,while elongation is relatively larger in SBR filled with superfine inorganic powder than that filled with carbon black. This indicates inorganic superfine powder is only an inert filler;when inorgan- ic superfine powder is added in tire flap compound to replace N330, the vulcanizate with 20 phr （parts per hundred rubber）inorganic superfine powder replaced N330 can meet the requirement of tire flap. Therefore,inorganic superfine powder can be partially replaced carbon black to produce tire flap com- pound to lower cost, increase benefit and to protect environment.
