Title:
RUBBER COMPOSITION IMPROVED IN STATIC-CHARGE BUILDUP AND PNEUMATIC TIRE MADE THEREFROM
Document Type and Number:
WIPO Patent Application WO1995031888
Kind Code:
A3
Abstract:
Disclosed are a rubber composition having an improved charging property which comprises 100 parts by weight of rubber component containing diene rubber of 90 parts by weight or more, and a filler of 30 to 120 parts by weight and a nonionic surfactant or phosphoric ester of 0.2 to 8 parts by weight, and a pneumatic tire charactrerized by that the above rubber composition having an improved charging property is used for the tread parts of the pneumatic tire. The typical examples of the nonionic surfactant and phosphoric ester are an adduct of ethylene oxide of 2 to 30 moles to linear, cyclic or branched, and saturated or unsaturated, and monohydric or polyhydric aliphatic alcohol having carbon atoms of 6 to 25, or an adduct of ethylene oxide of 2 to 30 moles to alkylphenol, and the compounds represented by the following formula (V): wherein R<5> represents a linear or branched, and saturated or unsaturated aliphatic hydrocarbon group having carbon atoms of 8 to 25, or an aryl group, and q and r each are an integer satisfying a relation of q + r = 1 to 30.
