摘要: Abstract A study of the mechanism gluing between plasma-modified styrene–butadiene elastomer (SBS) surfaces and polyurethane (PU) adhesives is presented in this paper. The plasma treatment was carried out employing low-pressure O2 generated by an RF discharge (13.56 MHz). FTIR–ATR spectroscopy peel tests were utilized to characterize SBS before after treatment. It found that hydroxyl groups are mainly created on surface their concentration reveals very good linear correlation with strength SBS–PU joints. grafting phenyl isocyanate (analog PU curing agent) into plasma-treated also investigated. process performed at 353 K, temperature which adhesive-bonded joints made. shown all react forming carbamate bonds. results obtained work strongly confirm conception adhesion chemical bonding PU.
