Title:
ADHESIVE COMPOSITION FOR ORGANIC FIBER CORDS, ORGANIC FIBER CORD-RUBBER COMPOSITE BODY, AND TIRE
Document Type and Number:
WIPO Patent Application WO/2021/220989
Kind Code:
A1
Abstract:
The present invention provides an adhesive composition for organic fiber cords, said adhesive composition being technologically characterized by containing (A) a synthetic rubber latex comprising an unsaturated diene, (B) gelatin and (C) an aqueous compound having a (thermally dissociative blocked) isocyanate group, and by not containing resorcin and formaldehyde. This adhesive composition for organic fiber cords enables the achievement of effects such as: (1) the environmental load is low since resorcin and formaldehyde are not used; (2) in a process where an organic fiber cord is covered with this adhesive composition for organic fiber cords and is subsequently dried and thermally cured, adhesion of this adhesive composition for organic fiber cords to a roll and the like is suppressed, thereby enabling the achievement of good workability; and (3) good adhesion is achieved between an organic fiber cord and a covering rubber composition.
