VULCANIZED RUBBER STABILIZER BASED ON UNSATURATED RUBBERS (OPTIONS) Russian patent published in 2002 - IPC

FIELD: rubber industry. SUBSTANCE: stabilizer contains 50-70% interaction product of butylphenol mixture (wt %: 2,6-di-t- butylphenol 0.5-2.0, 2,4-di-t-butylphenol 22-75, 2,4,6-tri-t-butylphenol 14-61, mono- and disubstituted butylphenols 10.5-15.0) with hexamethylenetetramine at weight ratio 100:(4-6) and 30-50% mixture of 6-ethoxysubstituted quinolines (wt %: 6-ethoxy-2,2,4-trimethyl-1,2- dihydroquinoline 5-20, 6-ethoxy-2,4-dimethylquinoline 15-20, N-acetyl-6-ethoxy- 2,2,4-trimethyl-1,2-dihydroquinoline 50-55, and resin based on 6-ethoxysubstituted quinolines 5-30). Stabilizer can further contain polymer of 2,2,4- trimethyl-1,2-dihydroquinoline. In this case stabilizer contains 5-25% of this polymer, 50-70% of above-indicated interaction product, and 15-35% of quinoline mixture. EFFECT: increased resistance to scorching of rubber compounds, reduced viscosity of the latter, and increased their plasticity. 2 cl, 4 tbl, 10 ex
