Abstract
In recent years, the high-performance aluminum pigments with bright color and optimal alkali resistance have received significant commercial applications. In this respect, the current study proposes a new method of preparing the colored aluminum pigment with excellent alkali resistance. The basis of the sandwich structure is the introduction of the Silica and fluoropolymer layers on the reactive dye. The morphology of the composite layers on the aluminum powder was characterized by scanning electron microscopy. The structure of the colored aluminum pigment was analyzed by Fourier transform infrared spectroscopy, energy dispersive spectroscopy and X-ray photoelectron spectroscopy. Moreover, the hydrogen evolution test was carried out using 5 wt % sodium hydroxide solution to study the alkali resistance. The findings from the study confirm that the colored aluminum pigment demonstrates specific sandwich structure, bright color, acid and alkali resistance and chemical stability.
