研究了轮胎橡胶粉 (GTR) 粉末的表面改性，以增强其对丁腈橡胶 (NBR) 硫化橡胶的粘合力。 GTR粉末的疏水表面通过大气压介质阻挡放电(DBD)转变为亲水表面。处理10秒以上后，水接触角从116°显着下降至0°。衰减全反射傅立叶变换红外光谱 (ATR-FTIR) 研究揭示了 GTR 粉末表面上 3298 和 1640 cm -1 处的峰强度增加，分别对应于 O―H 和 C=C。 X射线光电子能谱（XPS）分析进一步证实了常压等离子体处理后GTR粉末表面存在含氧极性官能团。改性 GTR 填充的 NBR 硫化胶的拉伸强度和撕裂强度得到改善，这归因于改性 GTR 和 NBR 基质之间增强的界面相互作用。 © 2009 Wiley periodicals, Inc.

The surface modification of ground tire rubber (GTR) powder to enhance its adhesion to nitrile rubber (NBR) vulcanizates was investigated. The hydrophobic surface of GTR powder has been transformed to a hydrophilic one through atmospheric pressure dielectric barrier discharge (DBD). The water contact angle dropped markedly from 116 to 0° after being treated for more than 10 s. Attenuated total reflectance Fourier transform infrared spectral (ATR-FTIR) studies revealed the increase in peak intensity at 3298 and 1640 cm -1 that correspond to O―H and C=C, respectively, on the surface of the GTR powder. The X-ray photoelectron spectroscopic (XPS) analysis further confirmed the presence of oxygen containing polar functional groups on the surface of the GTR powder after atmospheric plasma treatment. The improvement in tensile strength and tear strength was observed for the modified GTR-filled NBR vulcanizates, which is attributed to the enhanced interfacial interaction between modified GTR and NBR matrix. © 2009 Wiley Periodicals, Inc.
