Study on the synthesis of melamine cyanurate by continuous crystal seed cycling method
In this study,a nitrogen-sulfur synergistic and efficient melamine benzene sulfonate(MBSA)was syn-thesised and its structure and properties were characterised using Fourier transform infrared spectroscopy and ther-mogravimetric analyser.The MBSA was added into polyamide 6(PA6),and the flame retardancy and processabili-ty of MBSA/PA6 composites were evaluated by UL-94 rating and melt index.The results show that MBSA has ex-cellent thermal stability and its decomposition temperature is significantly higher than the processing temperature of PA6,making it suitable for processing applications at high temperatures.The MBSA/PA6 composites achieved UL-94 V0 rating at 8％MBSA addition.In addition,the addition of MBSA significantly increased the melt index of the composites and improved their processability for industrial production and moulding.This study reveals the great potential of MBSA as a flame retardant additive for PA6,which provides new ways and strategies to improve the performance and application of polyamide-based composites.
