Regulating the Microstructure of Intumescent Flame-Retardant Linear Low-Density Polyethylene/Nylon Six Blends for Simultaneously Improving the Flame Retardancy, Mechanical Properties, and Water Resistance

[Image: see text] A compatibilizer was melt-blended with intumescent flame-retardant linear low-density polyethylene/nylon six blends (LLDPE/PA6/IFR) by different methods, and the effect of microstructure on the flame retardancy, mechanical properties, and water resistance was investigated.

description [Image: see text] A compatibilizer was melt-blended with intumescent flame-retardant linear low-density polyethylene/nylon six blends (LLDPE/PA6/IFR) by different methods, and the effect of microstructure on the flame retardancy, mechanical properties, and water resistance was investigated. Melt-blending compatibilizers with LLDPE/PA6/IFR above the polyamide-6 (PA6) melt temperature formed the microstructure with IFR dispersion in the LLDPE matrix and good interphase adhesion between the PA6 phase and the matrix. Compared with the blends with the lack of compatibilizers, although good interphase adhesion improved the mechanical properties and water resistance, IFR dispersion in the LLDPE matrix reduced the flame retardancy sharply. To obtain the microstructure with IFR dispersion in the PA6 phase and strong interface adhesion of the PA6 phase with a matrix, a novel method in which a compatibilizer was melt-blended with LLDPE/PA6/IFR between the melt temperatures of LLDPE and PA6 was employed. The results showed that the flame retardancy, mechanical properties, and water resistance were improved simultaneously.
