The present invention relates to a fiber adhesive composition for reinforcing rubber beams. The present invention disclosed in the adhesive composition for rubber reinforcing fiber treatment to pre-treat the synthetic fibers such as aramid using a pre-treatment solution and to apply an adhesive solution to the pre-treated synthetic fibers; The pretreatment solution is classified into primary treatment solution and secondary treatment solution, and adhesive solution is classified into tertiary treatment solution and quaternary treatment solution, and the primary treatment solution is a mixture composition of epoxy, catalyst and water in a predetermined ratio. Isocyanate, catalyst and water are mixed in a predetermined ratio, and the tertiary treatment solution is vinyl pyridine (VP) latex, styrene-butadiene rubber (SBR) latex, resorcinol formaldehyde (RF) The initial condensate, and the quaternary treatment liquid is characterized in that the tertiary treatment liquid and water is diluted by a predetermined weight ratio. As such, by dividing epoxy and isocyanate, respectively, as a pretreatment agent for fibers and diluting water in a mixture of VP latex, SBR latex, and RF initial condensate, there is an advantage in that the adhesion stability of rubber latex is improved while the adhesion amount of rubber latex is small. . |
