Abstract

The rubber crumbs produced by the explosive circular destruction of worn-out automobile tires were studied. The crumbs showed high hydrophilicity. Their surface was analyzed by X-ray photoelectron spectroscopy. C, O, S, Zn, and Si were detected on the surface, and their chemical states were determined. The same chemical composition in the rubber crumb surface prepared by the explosive grinding of tires, as well as nanoglobules covering the crumb surface, was revealed. The appearance of polar groups on the crumb surface explains its high hydrophilicity and good compatibility with polymer matrices.

摘要

研究了废旧汽车轮胎爆炸粉碎产生的橡胶碎屑。这些碎屑表现出很高的亲水性。通过 X 射线光电子能谱分析了它们的表面，检测到了 C、O、S、Zn 和 Si，并确定了它们的化学状态。在轮胎爆炸粉碎制备的橡胶碎屑表面以及覆盖碎屑表面的纳米球中，都发现了相同的化学组成。碎屑表面出现的极性基团解释了其高亲水性和与聚合物基体的良好相容性。
