FIELD: rubber industry. ^ SUBSTANCE: tire-destination rubber compound comprises: (i) mixture of 10-90 wt parts of polydiene or diene/vinylatomatic copolymer with 10-90 wt parts of copolymer of butadiene or butadiene and styrene (alpha-vrthylstyrene) with (meth)acrylic acid methyl ester, beta-hydroxyethyl ester, beta-hydroxypropyl ester, beta-(N,N-dimethylamino)ethyl ester, beta-(N,N-diethylamino)ethyl ester, beta-(N,N-dimethylamino)propyl ester, or beta-(N,N-diethylamino)propyl ester at weight ratio of butadiene/styrene(alpha-methylstyrene)/ester (99.5-40.0):(0-40.0):(0.5-20.0), respectively; (ii) 2-10 wt parts of aminosilane coupler selected from group including beta-aminoethoxytriethoxysilane, reaction product of monoethanolamine with tetraethoxysilane or polyphenylethoxysilane, or polyethoxysiloxane at weight ratio 1:(1-4), or mixture of aminosilane coupler with bis(3-triethoxysilylpropyl)tetrasulfide at weight ratio (1-10): 1; (iii) 5-80 wt parts of silicic acid filler; (iv) 0-80 wt parts of carbon black; and (v) 10-45 wt parts of special-destination additives. ^ EFFECT: improved elasto-viscosity, elastic, and wear-resistant characteristics, and reduced heat buildup. ^ 2 tbl, 34 ex |
