LATEX, BONDING LIQUID, FIBER MEMBER, AND COMPOSITE MATERIAL COMPRISING FIBER MEMBER AND VULCANIZED RUBBER MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a bonding liquid for forming an adhesive composition layer high in binding capacity and assuring excellent adhesion between a vulcanized rubber member and a fiber member.

SOLUTION: The bonding liquid comprises a nitrile group-containing copolymerized rubber latex, whereinα-,β-ethylenic unsaturated nitrile based monomer units account for 10-30 wt.%, iodine value is not more than 250, Mooney viscosity (ML1+4, 100°C) is 10-120, and the difference between the extrapolated glass transition initiation temperature (Tig) and extrapolated glass transition end temperature (Teg) determined by differential scanning calorimetry is not higher than 15°C, and a resorcinol formaldehyde resin.
