摘要：
In this work, a co-microcapsule of magnesium hydroxide (MH) and red phosphorus (RP) (denoted as M [MH&RP]) was synthesized using 4, 4'-diphenylmethane diisocyanate and melamine via one-step in-situ surface polymerization, which was subsequently introduced into ethylene vinyl acetate copolymer (EVA) as a flame retardant. The results indicate that the core-shell structured co-microcapsule displays increased thermal and thermo-oxidative stability as well as better dispersion in EVA. Flame retardancy of the EVA/M[MH&RP] composite improves significantly in comparison with the EVA/MH/RP composite due to formation of continuous and compact char layer on the surface of the composite. Moreover, this flame-retardant composite exhibits excellent water and acid resistance. The addition of a small amount of multi-walled carbon nanotube (MWCNT) further increases flame retardancy of the EVA/M[MH&RP] composite considerably and the flame-retardant EVA/M[MH&RP]/MWCNT composite has good mechanical flexibility and electrical insulation. This work has provided a simple method to prepare multi-functional flame-retardant EVA composite. (C) 2019 Elsevier Ltd. All rights reserved.
