FIELD: chemistry.SUBSTANCE: invention relates to rubber mixtures which are especially suitable for tyre treads. The rubber moulding composition for making tyre treads contains a halobutyl elastomer, at least one additional elastomer, mineral filler and at least a three-component mixed system of modifiers which contains silane, phosphine and an additive which contains at least one hydroxyl group and a functional group which contains a basic amine, the modified being added in an amount which provides a) ultimate elongation of samples of at least about 300%; b) tangent ? at 0°C greater than 0.36; c) tangent ? at 60°C less than 0.120; d) abrasion volume loss (DIN) less than 165 mm; e) breaking strength greater than 13.0 MPa. A method of preparing said mixtures is also disclosed.EFFECT: mixtures are especially suitable for tyre treads and exhibit improved processing characteristics, traction force, rolling resistance and wear resistance.16 cl, 6 dwg, 48 ex |
