An aqueous composition comprising an alkaline rubbery vinyl pyridine latex, a water dispersible or soluble epoxide and a polyfunctional amine can be used to treat a polyamide reinforcing element, e.g. a poly(p-phenylene terephthalamide) cord, to increase the adhesion of the cord to rubber. Further improvements in adhesion can be obtained if the cord before treatment with the aqueous composition is exposed to a cold gas plasma of air, N₂, He, Ne or Ar or mixture thereof at up to about 300 watts of power for a few seconds to several minutes to improve its adhesion to rubber.
由碱性橡胶乙烯基吡啶胶乳、水分散或可溶环氧化物和多官能胺组成的水性组合物可用于处理聚酰胺补强元件,例如聚对苯二甲酰对苯二胺帘线,以增加帘线与橡胶的粘合力。如果在使用水性组合物处理帘线之前,将其暴露于空气、N₂、He、Ne 或 Ar 或其混合物组成的冷气体等离子体中,以高达约 300 瓦的功率持续数秒至数分钟,以改善其与橡胶的粘附性,则可进一步改善粘附性。
