Adhesive and Processing Concepts for Tire Reinforcing Materials

Source

A tire can be considered to be a composite of a reinforcing structure material and rubber compound. The reinforcing materials play a major role in tire performance. Several important contributing characteristics of the reinforcing materials are tensile, modulus, dimensional stability, fatigue, and adhesion under tire operating conditions. For optimum tire performance, adequate adhesion between the reinforcing material and the rubber compound is essential.

Choice of adhesive system(s) is dependent upon the nature of the substrates (fiber and rubber) to be bonded, as well as adhesive properties. Conventional resorcinol-formaldehyde-latex adhesion systems provide required adhesion for rayon, nylon, and fiberglass. Polyester and aramid require the use of reactive chemicals.

Time, temperature, and tension variables are required for processing organic fibers to tailor the fiber properties to a specific end use. Fabric properties such as modulus, shrinkage, and fatigue can be modified by varying processing conditions. Heat setting of the adhesive is also obtained during processing. Therefore, it is imperative that processing conditions be selected to achieve optimum fabric properties as well as adequate adhesion.

Processing and adhesive concepts used for organic fibers are reviewed. Effect of energy and environmental factors on the design and operation of the processing units is also discussed.
