TIRE WHICH ROLLING SURFACE CONTAINS EMULSION BUTADIENE-STYRENE RUBBER WITH HIGH CONTENT OF TRANS-LINKS Russian patent published in 2016 - IPC C08L9/06 B60C1/00 C08L7/00 C08L9/00 C08K5/01 C08L91/00 C08L93/00 

FIELD: chemistry.

SUBSTANCE: invention relates to tire rolling surface which contains a rubber composition containing at least: from 35 to 65 phr emulsion butadiene-styrene copolymer "E-SBR" called the first diene elastomer, in which the share of butadiene links of trans-1,4 structure is more than 50 % of the weight of all butadiene links; from 35 to 65 phr polybutadiene (BR) as the second diene elastomer; optionally, from 0 to 30 phr another diene elastomer, referred to as the third diene elastomer; from 90 to 150 phr intensifying inorganic filler; plasticizing system containing: number A: in the interval between 10 and 60 phr, hydrocarbon resin, characterized by the Tg is more than 20 °C; quantity B: in the range between 10 and 60 phr, plasticizer and, liquid at 20 °C, Tg is less than -20 °C; provided that the total amount of plasticizers, a + B is between 50 and 100 phr.

EFFECT: application of emulsion SBR and polybutadiene (BR) in combination with an inorganic filler and plasticizer for tire rolling surface enables to obtain improved adhesion with wet road and improved wear resistance, without deterioration of rolling resistance.
