Modification of Recycled Melamine-Formaldehyde Plastic on Polypropylene

Abstract:

The modification process of recycled melamine-formaldehyde(MF) plastic on polypropylene(PP) has been studied, and the optimal compounding parameters were obtained by twin extruding system in this paper. The results showed that with increasing of recycled MF plastic in PP, the tensile strength, elongation at break, molding shrinkage and impact strength decreased, the modulus, heat distortion temperature(HDT) and melt flow rate(MFR) increased, which indicates that the addition of recycled MF plastic can improve rigidity, heat resistance, size stability and flowability of PP. More importantly, the oxygen index(OI) of PP was increased with the addition of recycled MF plastic, which indicates that recycled MF plastic can improve the flame-retardant property of PP.
