Title:
RUBBER COMPOSITION FOR HOSE, TRANSMISSION OIL PIPELINE FOR MOTOR VEHICLE, AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/149303
Kind Code:
A1
Abstract:
A purpose of the present invention is to provide a rubber composition for hoses which, only through primary crosslinking, can form cured objects excellent in terms of hardness and elongation at break. This rubber composition for hoses comprises a carboxyl-containing terpolymer having constituent units of ethylene, of a (meth)acrylic acid ester, and of a carboxylated monomer, hexamethylenediamine carbamate, diazabicycloundecene, carbon black, and a plasticizer, wherein the carbon black is contained in an amount of 77-87 parts by mass per 100 parts by mass of the terpolymer. The present invention further relates to a transmission oil pipeline for motor vehicles which is formed from the rubber composition for hoses and a method for producing the transmission oil pipeline for motor vehicles.
