Research Progress of Guanidine Phosphate Flame Retardant Application Technology
Guanidine phosphate has both phosphorus and nitrogen elements,and can form an intumescent flame retardant system in the flame retardant application of cellulose materials,with significant charcoal formation and smoke suppression effect.In this paper,the preparation process and flame retardant mechanism of guanidine phosphate are sorted out,and the process of preparing guanidine phosphate using phosphoric acid and guanidine carbonate is the simplest.At the same time,the flame retardant applications of guanidine phosphate in paper,wood,fabrics and other fields are summarized,and the future research ideas of guanidine phosphate as a flame retardant are proposed.
