A simple, effective and inexpensive method was proposed to reuse ground tire rubber (GTR) powder by preparing a superhydrophobic surface via a molding process. The obtained superhydrophobic surface was based on low-density polyethylene (LDPE) / ground tire rubber (GTR) thermoplastic elastomers (TPEs) where the styrene-butadiene-styrene block copolymer (SBS) was used as compatibilizer and series sandpapers were used as templates. The mechanical properties, hydrophobic properties, surface morphology and self-cleaning property were investigated systematically. The results showed that both of the mechanical properties and superhydrophobicity could be greatly improved with a certain amount of SBS. The superhydrophobic surface based on molded LDPE/SBS/GTR (weight ratio = 40/15/60) TPE exhibited excellent superhydrophobicity (with a contact angle of 164.6° ± 3.0° and a tilt angle of 4.4° ± 1.9°). Furthermore, abundant tearing microstructure could be found obviously by morphology observation. Optical images indicated the surface possessed of low adhesion force and self-cleaning property.

提出了一种简单、有效且廉价的方法，通过成型工艺制备超疏水表面来重复使用轮胎橡胶 (GTR) 粉末。获得的超疏水表面基于低密度聚乙烯（LDPE）/磨碎的轮胎橡胶（GTR）热塑性弹性体（TPE），其中苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）用作增容剂，系列砂纸用作模板。系统地研究了机械性能、疏水性能、表面形貌和自清洁性能。结果表明，一定量的SBS可以大大提高机械性能和超疏水性。基于模塑 LDPE/SBS/GTR（重量比 = 40/15/60）TPE 的超疏水表面表现出优异的超疏水性（接触角为 164。6° ± 3.0° 和 4.4° ± 1.9° 的倾斜角）。此外，通过形态观察可以明显地发现丰富的撕裂微观结构。光学图像表明表面具有低附着力和自清洁性能。
