Water-based liquid for treating glass fiber cord, glass fiber cord for reinforcing rubber and reinforced rubber product

摘要

A water-based liquid for treating a rubber-reinforcing glass fiber cord, which contains as a solid component a composition consisting essentially of: (1) a rubber latex, (2) 10 to 70% by weight of an alkylated chlorosulfonated polyethylene latex, and (3) 5 to 20% by weight of a water-soluble resorcinol-formaldehyde condensate, the amounts of (2) and (3) being based on the total amount of (1) and (2). The liquid can be used to provide a coated glass fiber cord for use in the reinforcement of a rubber. A rubber product reinforced with the coated glass fiber cord has excellent fatigue resistance under heat and a flexing force.
