Annotation

Intumescence is a result of synergic effect of three components: charring source, char promoter and foaming agent. Phosphoric acid derivatives, are an object of interest of many researches and flame retardants industry potentates. As an intumescence mechanism component, melamine salts combines two out of three key features, char promotion and gasses generation. As part of the work, a complex compound based on a high nitrogen content substance bis(melamine phosphate)copper (II) phosphate (CUMP) was introduced into high-density polyethylene (PE-HD) and subjected to a flammability and smoke emission tests. The influence of a novel intumescent fire retardant (IFR) addition on the properties of polymer was determined by static tensile test, thermogravimetric analysis (TGA), as well as cone calorimetry (CCT) and single-chamber tests. Moreover, microstructure of the materials and char residue after cone calorimetry test were investigated by scanning electron microscope (SEM). The material containing 20 wt% of CUMP were characterized by ability to form a less combustible char layer inhibiting the decomposition process. The results were compared to those for unmodified polyethylene and a polymer containing 20 wt% of ammonium polyphosphate (APP). New IFR compound has an effect on flame retardancy of polyethylene, comparable to or even greater than commonly used ammonium polyphosphate.
