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

FIELD: machine building.

SUBSTANCE: invention discloses a bus, the rolling surface of which contains a rubber composition containing at least the following: from 40 to 100 phr emulsion butadiene-styrene copolymer "E-SBR", called first diene elastomer, in which the share of butadiene links structure TRANS-1.4 is more than 50 % of the weight of all butadiene links; optionally, from 0 up to 60 phr another diene elastomer, called second diene elastomer; from 90 to 150 phr intensifying inorganic filler; plasticizing system containing: number A: between 10 and 60 phr, hydrocarbon resin with Tg higher than 20 °C; b: between 10 and 60 phr, plasticizer, 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: using this emulsion SBR in combination with high content of inorganic filler and plasticizer for tire rolling surface allows obtaining improved adhesion with wet road without deterioration of the rolling resistance.
