摘要:
采用动态硫化法制备了高密度聚乙烯(HDPE)/丁苯橡胶(SBR)热塑性硫化胶(TPV),以金相砂纸为模板制得系列具有超疏水性的HDPE/SBR TPV薄膜,研究了模压HDPE/SBR TPV薄膜表面的稳定性及不同规格砂纸对模压HDPE/SBR TPV薄膜疏水性能的影响;构建了一种新型可连续工作的油水分离装置,研究了HDPE/SBR TPV薄膜卷绕物的间隙和抽力对油水分离的影响规律,对HDPE/SBR TPV薄膜表面的微观结构进行了表征,并提出了油水分离机制。结果表明,使用W 14型砂纸模压所得HDPE/SBR TPV薄膜的疏水性能最佳,接触角约为159.2 °,且倾斜角仅约为7.2 °;当油水分离装置中HDPE/SBR TPV薄膜卷绕物的膜间隙为50 μm、相对真空度为3 kPa时,油水分离性能最佳,油水分离效率可达98.53%。
Abstract:
High density polyethylene (HDPE)/styrene-butadiene rubber (SBR) thermoplastic vulcanizates (TPV) were prepared by dynamic vulcanization and metallographic sandpapers were used as the template to prepare a series of molded HDPE/SBR TPV films with super hydrophobicity.The influence of sandpaper type on the hydrophobi-city and the stability of molded HDPE/SBR TPV films were studied systematically.Moreover, a new oil-water separating equipment was constructed which could achieve continuous oil-water operation.The influence of different film gap and relative vacuum degree on the oil-water separation were researched and the microstructure of the surface of the molded HDPE/SBR TPV films was observed and mechanism of oil-water separation behavior was proposed.The result showed that when the metallographic sandpaper with W 14 type was used as template, the water contact angle of the molded HDPE/SBR TPV surface was 159.2 ° and the rolling angle of the molded HDPE/SBR TPV surface was just 7.2 °.When the film gap of the molded HDPE/SBR TPV film in the oil-water separating equipment and the relative vacuum were 50 μm and 3 kPa respectively, the optimal oil-water separating performance could be reached with the separation efficiency of up to 98.52%.
