Adhering textile materials to rubber

摘要

Rubber is adhered to textile material (cotton, rayon or nylon) by applying trimeric methyleneaminoacetonitrile and either 1,5-naphthalene diol or a meta disubstituted benzene in which each of the substituents is a -OH, -NH2 or -OCOCH3 radical and heating to condense the resin. The rubber may be natural rubber, polybutadiene, polyisoprene, butadiene-styrene rubber or nitrile rubber. The adhesive ingredients may be applied directly to the textile, compounded in the rubber stock or incorporated in the latex solutioning bath in an amount of 0,5 to 8 parts (total) per 100 of rubber. Other compounding ingredients may be added to the rubber and the whole mass cured. The cords may be solutioned in a conventional bath. Rayon cords are dipped in a bath consisting of butadiene-vinyl pyridine latex (20 parts) butadiene-styrene latex (80 parts) partially reacted resorcinol/formaldehyde resin (8 parts), ammonia (0,5 parts) and formaldehyde (2 parts) at a concentration of 15-20% solids. The bath for nylon cords consists of butadiene-vinyl pyridine latex (100 parts), partially reacted resorcinol (formaldehyde resin (15 parts), ammonia (0,9 parts) and formaldehyde (4,25 parts) in a 15-20% solids concentration.ALSO:Textile materials comprising cotton, rayon or nylon are adhered to rubber (natural or synthetic) by applying trimeric methyleneaminoaceto-nitrile and either 1,5-naphthalenediol or a meta-disubstituted benzene in which each of the substituents is a -OH, -NH2 or -OCOCH3 group. The adhesive ingredients may be applied directly to the textile, compounded in the rubber stock or incorporated in a latex solutioning bath. Rayon cords are dipped in a bath comprising butadiene/vinyl pyridine latex, butadiene/styrene latex, partially reacted resorcinol/formaldehyde resin, ammonia and formaldehyde. Nylon cords are dipped in a bath comprising butadiene/vinyl pyridine latex, partially reacted resorcinol/formaldehyde resin, ammonia and formaldehyde.
