Preparation and characterization of PMMA/flaky aluminum composite particle in the presence of MPS

Abstract In order to enhance corrosion resistance of aluminum pigments, PMMA/flaky aluminum composite particle was prepared in the presence of MPS by means of in situ emulsion polymerization of MMA. It was found that the PC and CE could attain 9.1% and 45.5%, respectively at the conditions of m(MPS)/m(Al) = 20%, time = 20 h, and temperature = 55 °C in the process of coupling. As for the in situ emulsion polymerization, there were obvious increases in both PG and GE when PC was increased from 0 to 1.2% or more, showing that more PMMA had been formed on the surface of aluminum in the presence of MPS. PG and GE reached the highest value of 20.5% and 54.1%, respectively when CCTAB was 0.94 mmol/L (a little higher than CMC). The analysis of FT-IR and EDS indicated that PMMA/flaky aluminum composite particle had been successfully prepared, and evolved hydrogen detection showed that corrosion resistance of aluminum pigments had been remarkably improved in the presence of MPS.
