polyamide adhesive to attach to rubber and versterkingselement of polyami - and method to give a far - sterkingselement of polyamide to rubber.

摘要

An aqueous alkaline dispersion of a rubbery vinyl pyridine copolymer, trimethylol phenol, and a resorcinol compound, in certain amounts is useful in forming an adhesive for bonding polyamide or nylon cords to rubber compounds or stocks. After dipping the cord in the adhesive dip, the coated cord is heated to dry it and heat cure or heat set the adhesive on the cord. Thereafter, the adhesive containing cord is combined or laminated (calendered) with a curable rubber compound and the resulting assembly is cured. High H-adhesions are obtained with this one-step or single treatment coating dip. It is particularly useful for bonding crystalline polyamides having a large number of aromatic groups in the polymeric structure, e.g., "Fiber B".
