COMPOSITION RESISTIVE MATERIAL Russian patent published in 1995 - IPC

FIELD: electronic engineering. SUBSTANCE: composition resistive material containing current-conductive phase on the basis of technical carbon, zinc oxide, barite concentrate and binder on the basis of butylrubber with vulcanizing system on the basis of chloroprene rubber, stearin, hexachloro-p-xylene and p-tret.-alkylformaldehyde resin has additionally stabiloil. Binder source is industrial butylrubber and resin p-tert.-alkylphenolformaldehyde resin at the following ratio of components, wt.-% industrial butylrubber 51-55; chloroprene rubber 2.56-2.73; zinc oxide 1.54-1.64; stearin 1.54-1.64; technical carbon 21.17-28.04; barite concentrate 775-8.10; hexachloro-p-xylene 0.22-0.52; p-tert.-alkylphenolformaldehyde resin 5.75-7.10, and stabiloil 1.6-2.1. Composition material provides minimal deviation of temperature heating of total ready article square at the limits 0.4 degree at the temperature ranges 25-40 C and ensures to decrease of ready article cost. EFFECT: enhanced quality of material. 5 tbl
