A novel intumescent flame retardant low-density polyethylene (LDPE) composite was prepared based on bamboo fiber (BF) and silica-gel microencapsulated ammonium polyphosphate (MCAPP). The synergistic effects between BF and MCAPP on the flame retardant and thermal properties of flame retardant LDPE composites were investigated. The results show that the flame retardant properties of LDPE composites are influenced by the weight ratio of BF and MCAPP. The higher content of MCAPP, the better flame retardant property can be obtained. When the ratio of BF/MCAPP is 1:1, the flame retardant LDPE composite shows excellent flame retardant properties.

A char forming agent (CFA) and silica-gel microencapsulated ammonium polyphosphate (Si-MCAPP) were selected to form novel intumescent flame retardant system to prepare flame retardant polypropylene (PP) composites, and then the influences of nanoporous nickel phosphates (NiP) on the thermal and flame retardant properties of flame retardant PP composites were studied by the real time FTIR (RTFTIR) spectra, limited oxygen index (LOI) test, and the scanning electron microscopy. RTFTIR shows the addition of NiP can improve the thermal stability of flame retardant PP composites. LOI test shows LOI value is increased with the increase of the content of NiP, and the optimized concentration of NiP is 1.0%. Furthermore, smoke toxicity of the novel flame retardant PP composites was studied by mice experiment. The upper limit of the no death smoke concentration of the composite is 12.37 mg/L.
