用贝壳废弃物制备砂浆超疏水涂层的试验研究

Experimental Study on Utilization of Shell Waste for Preparation of Superhydrophobic Mortar Coating

摘要: 随着我国贝壳产量的日益增长，贝壳废弃物已经成为沿海城市的环境问题。本论文利用贝壳废弃物与硬脂酸反应，制备了一种超疏水涂层，并对超疏水砂浆试块进行了红外、润湿性、耐腐蚀性能、耐磨损性能、吸水率和自清洁性能测定。结果表明：硬脂酸牢固地键合在贝壳表面，制备的超疏水砂浆试块具有良好的耐磨损性能和自清洁性能。

Abstract: With the increasing production of shells in China, shell waste has become an environmental prob-lem in coastal cities. In this paper, a superhydrophobic coating was prepared by the reaction of shell waste and stearic acid. The infrared spectrum, wettability, corrosion and wear resistance, water absorption and self-cleaning properties of the superhydrophobic mortar specimens were researched. The results show that the stearic acid was firmly bonded on the shell surface, the prepared superhydrophobic mortar specimens has good wear resistance and self-cleaning per-formance.
