Rubber-to-steel bonding studies using a rubber compound strip adhesive system
An efficient adhesive system consisting of a primer and a solid rubber compound strip was developed for bonding rubbers to steel. The effects of carbon black and phenol formaldehyde (PF) resin contents in the strip compound on the peel strength were determined. The optimum thickness of the rubber strip to attain maximum bond strength was determined. A comparative evaluation of this strip adhesive system with a commercial solution adhesive was done. The effect of bonding temperature an the peel strength, ageing resistance, and salt water resistance of the bonded system was also investigated. The strip compound with optimum properties gives comparable strength when bonded and gives a better storage life than the solution adhesive. This bonding system also uses a smaller amount of solvents and thus should cause less pollution.
