Double Hydroxides

Mg-Al-Fe ternary layered double hydroxides (LDHs) were synthesized based on Red mud by a calcination-rehydration method, and characterized using X-ray diffraction (XRD). The flame-retardant properties of EVA/LDHs (EVA, ethylene-vinyl acetate) composites were studied via cone calorimeter test (CCT), smoke density test (SDT), and Thermogravimetric analysis (TGA). The CCTs data indicate that heat release rates (HRR) of EVA/LDHs composites decrease in comparison with that of EVA, EVA/Red mud, EVA/ATH and EVA/MH composites. The SDT results show that LDHs is helpful to smoke suppression. The TGA show that LDHs-containing EVA2 has higher thermal stability at high temperatures than the other samples.

Tga Analysis

The structure, thermal behavior and flame retardant properties of polypropylene (PP) nanocomposites treated with complex flame retardants composed of layered double hydroxides (LDH) and ammonium polyphosphate (APP)/pentaerythritol (PER) intumescent flame retardant systems have been investigated by XRD, TEM, LOI, UL-94, and TGA analysis. The results showed that introduction of LDH nanofillers into the samples can obtain good flame retardant synergistic effects with APP/PER additives at appropriate LDH loadings. Such synergism between LDH and APP/PER in PP matrix can be explained by a proposed condensed phase flame retardant mechanism. And based on this study, different types of modified PP products were developed in a ten-thousand-ton scale to be used for the automobile industries, such as car bumpers and dashboards.
