ABSTRACT

The effect of basalt powder (BP) as a waste filler on the properties of polyurea (PUA) has been investigated. The BP was added into a two-component quick-setting polymeric matrix and formed by spray forming. The characterisation of the composites manufactured using waste inorganic particulate filler was performed using mechanical testing (static tensile test and hardness measurement), thermomechanical analysis (Vicat softening temperature – VST and dynamic thermomechanical analysis – DMA) and thermogravimetric analysis (TGA). Properties of the pure PUA and PUA-composites were discussed in reference to structural analysis proceeded by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The addition of BP into PUA allows improving the overall performance of spray-formed material properties. Composite filled with 20 wt-% of the BP showed the most beneficial set of mechanical properties with simultaneously improved thermomechanical and thermal properties.

摘要

研究了玄武岩粉（BP）作为废填料对聚脲（PUA）性能的影响。将BP添加到两组分速凝聚合物基体中，并通过喷雾成型形成。使用机械测试（静态拉伸测试和硬度测量），热机械分析（维卡软化温度– VST和动态热机械分析– DMA）和热重分析（TGA）对使用废无机颗粒填料制造的复合材料进行表征。参照通过扫描电子显微镜（SEM）和傅里叶变换红外光谱（FTIR）进行的结构分析，讨论了纯PUA和PUA复合材料的性能。在PUA中添加BP可以改善喷涂材料性能的整体性能。
