摘要
The key of leather flame retardant technology is the development of flame retardant materials. A novel intumescent flame retardant (IFR), as the flame-retardant intermediate, was firstly synthesized, then a novel nanocomposite was successfully prepared from the IFR and montmorillonite modified by cetyl trimethyl ammonium bromide (CTAB) and collagen. Its structure and properties were characterized by XRD and FT-IR. The flame retardant was added to leather and its effects on flame-retardant properties of leather were studies by vertical burning test, limiting oxygen index (LOI) test and cone calorimeter test, respectively. The thermal stability and morphology of the flame-retardant leather were characterized by TG and SEM. The results showed that the novel nanocomposite has good flame-retardant properties and can enhance the fire retardancy of leather effectively. (C) 2015 Elsevier Ltd. All rights reserved.
