Abstract

A new type of amino resin nanocomposite (THPS-OMMT-MDFP) was synthesized from an amino resin (MDFP), tetra-hydroxymethyl phosphonium sulfate (THPS) and modified montmorillonite (OMMT) by an intercalation compounding method. It was characterized by FT-IR, XRD and TG/DTG and applied to the preparation of flame-retardant hide powder and leather. The results of DSC, vertical burning test and the Oxygen Index (OI) showed that the flame-retardant hide powder showed a higher activation energy compared with hide powder and that the flame retardancy and thermostability of the flame-retardant leather had been remarkably improved. As a whole, the results demonstrated that this nanocomposite had good flame-retardant performance and could be widely used in leather.
