ADHESIVE COMPOSITION FOR RUBBER AND FIBER, CORD FOR REINFORCING RUBBER AND PRODUCTION OF THE CORD

摘要

PROBLEM TO BE SOLVED: To obtain an adhesive composition for rubber and fiber exhibiting adhesivity to the rubber even in a reduced amount of the adhesive adhered on the fiber, and a cord for reinforcing rubber which holds the characteristic properties of the fiber, which can exhibit a cord property excellent in flexibility, and which has improved adhesivity, that is, excellent adhesive strength drawing power) and excellent adhesion to the rubber on peeling, and improved fatigue resistance, and to provide a method for manufacturing the cord. ;SOLUTION: This adhesive composition for rubber and fiber is obtained by compounding an adhesive matrix component with silicic anhydride. The first treating liquid containing the adhesive composition for rubber and fiber is imparted to twisted fibers, and the fibers are heat-treated. Subsequently, the second treating liquid containing a mixture (RLF) of an early condensate of resorcin and formaldehyde, and a rubber latex is imparted to the treated fibers, and the fibers are subjected to a heat-treatment to obtain the objective cords for rubber reinforcement.;COPYRIGHT: (C)2001,JPO
