    • PROBLEM TO BE SOLVED: To provide a composition for producing a binder pitch used for producing carbon articles in which randomly arranged carbon fibers are distributed over the whole bodies, and to provide a method for producing the binder pitch.
      SOLUTION: Carbon fiber bundles may be dispersed into substantially single monofilaments in pitch by stirring a mixture of fibers and pitch at a temperature at which the pitch has a viscosity of about 0.1 to about 5 poise. The resulting fiber pitch binder contains about 0.5 to about 10.0 wt.% carbon fibers substantially dispersed as substantially single monofilaments which are randomly oriented, which may then be used directly as a binder for producing carbon bodies, for example, graphite electrodes, pin stock or specialty graphite articles. This unique binder using an economical amount of carbon fibers has the capacity to increase the strength and reduce the coefficients of thermal expansion of the resulting carbon products in more than one direction.

    • 待解决的问题:提供一种生产用于生产碳素制品的粘合剂沥青组合物,其中随机排列的碳纤维分布在整个机体上,并提供一种生产粘合剂沥青的方法。 解决方案:在沥青具有约0.1至约5泊的粘度的温度下,碳纤维束可以通过在纤维和沥青的混合物之间搅拌而分散在基本上单个单丝中。 所得到的纤维沥青粘合剂含有约0.5至约10.0重量%的碳纤维,其基本上分散为基本上单独的单丝,其随机取向,然后可直接用作生产碳体的粘合剂,例如石墨电极,针料或 特种石墨制品。 使用经济数量的碳纤维的这种独特的粘合剂具有增加强度并降低所得碳产品在多于一个方向上的热膨胀系数的能力。 版权所有(C)2006,JPO&NCIPI
