POLYMERIC COMPOSITION OF FRICTION PURPOSE Russian patent published in 1995 - IPC

FIELD: polymeric materials. SUBSTANCE: polymeric composition has, mas. p. : butadiene-containing rubber 100; phenolformaldehyde resin 25.0-58.8; sulfuric vulcanizing group 22.2-82.0; alumina 17.3-50.9; mineral filler 68.2-177.6; carbon-containing filler 20.6-88.3; cellulose 10.0-57.2; flax boon and/or milled and thermic treated at 150-200 C for 30-90 min cereal straw 15.0-71.4, and cement 100-229. Linear wear for sample pair (material of contra-body is gray cast iron, at 110 ± 10 C, slipping rate is 7.0-7.5 m/s, specific loading is 27 H/сm², test period is 2 h, friction moment is 11.6 ± 1 H x m) is 0.02-0.03 mm, friction coefficient is 0.50-0.54. Sample mass increase (at 20 C for 4 h) in distilled water is 0.8%, in car oil АСП-10У is 0.7-0.8%. Polymeric composition is used in car break of drum type. EFFECT: improved ecology, enhanced quality of composition. 2 tbl
