METHOD FOR PRODUCTION OF RUBBERIZED MATERIALS Russian patent published in 1995 - IPC

FIELD: production of rubberized materials. SUBSTANCE: method for production of rubberized materials includes introduction into adhesive composition based on unsaturated polymer after introduction of ingredients of 0.5-3.0 mas.p. of dioxide of dinitrile of 2.4,6-trimethylbenzene-1,3- dicarboxylic acid per 100 mas.p. of polymer. Composition is applied by spreader to base. Conducted simultaneously is vulcanization at 50-80 C. Possible also is introduction of dioxide of dinitrile 2,4,6- trimethylbenzene-1,3-dicarboxylic acid into adhesive composition in form of 3-5% solution in ethyl acetate. Material characteristics with coatings from SKI-3 and SKD-SRS (50-50): breaking load of strip of rubberized cloth with working area of 50x200 mm of warp 900-950 N, of weft 650-794 N; waterproof; strength of cohesion with cloth in separation, before ageing, 10.5-17.4 N/cm; after ageing; 4.8-11.8 N/cm. EFFECT: higher efficiency. 2 cl, 15 tbl
