Method of producing binder for electrodes

专利摘要:
The invention relates to carbon-containing materials, in particular the preparation of a carbon binder for electrodes used in electrochemistry. To increase the quality of the target product with a high content of primary quinoline-insoluble components (molar ratio C: H 3.69-4.06), other carbon-containing components are used. The process is carried out by mixing coal tar pitch (i.e. 60-80 ° C) with oil distillate (formed by coking a solid coal-deck at 950-1150 ° C) at a mass ratio of (1-3) :( 3: 1). The resulting mixture is distilled under a pressure of 0.005-0.12 MPA to obtain a residue with m.p. 90-130 ° C. The latter is mixed with a fraction of coal tar with an average bp. above 350 ° C to obtain a binder with a given softening point. The resulting binder has, for example, t.razm. when the content is not soluble in toluene components 27.3%; insoluble in quinoline - 1.4%, residue after coking according to Conradson - 51.6%, C: H ratio insoluble in quinoline 3.96.
