Abstract

PURPOSE: The titled composition, prepared by incorporating a specific carbon black and an extender oil with a rubber containing natural rubber, styrene- butadiene copolymeric rubber (SBR) and polybutadiene rubber (BR), having improved damping ability on snowy and wet road surfaces and improved abrasion resistance, and useful for large-sized cars.
CONSTITUTION: 45W60pts.wt. carbon black having an iodine absorption ≥80mg/l and a dibutyl phthalate absorption ≥70ml/100g and 5W15pts.wt. extender oil containing 20wt% or more, preferably 50wt% or more, oil having a pour point ≤-10°C and the rest having a pour point ≤10°C are incorporated with 100 pts.wt. rubber containing 50W90pts.wt. natural rubber and/or polyisobutylene rubber, 5W30pts.wt. styrene-butadiene copolymeric rubber (SBR) with a styrene content ≤20wt% and 5W45pts.wt. polybutadiene (BR) with a cis 1,4-bond content ≥95wt%. An oil containing more paraffinic compounds than aromatic compounds is useful as the extender oil.
