“…Addition of PP-g-MAH gives slightly better mechanical properties. Suihkonen et al [14] examined a similar problem. Mg(OH) 2 silanization using 3-aminopropyltriethoxysilane produced unfavorable results: there was an increase in the Young's modulus but a fall in the values of the other mechanical parameters, including by 40% for elongation at break.…”

“…The thermal stability allows it to be combined with epoxy resins [14] in addition to its classical composites with ethylene vinyl acetate (EVA), polypropylene (PP) and polyethylene (PE). However, Mg(OH) 2 has a low efficiency as a flame retardant and the high concentration necessary may impair the mechanical properties of the resulting composite.…”

“…The work examined how the Mg(OH) 2 particle size and surface modifications with silanes affected the flame retardant, thermal and mechanical properties. Even in small quantities Mg(OH) 2 with small particle sizes can achieve similar or superior flame retardant performance compared with mico-sized particles [14].…”

Functional polypropylene composites filled with ultra-fine magnesium hydroxide

Magnesium hydroxide was prepared under controlled conditions from aqueous Mg(NO 3 ) 2 and NaOH solutions. The small, nanoplate-shaped particle size distribution was monomodal from 164 to 459 nm. Functional polypropylene/Mg(OH) 2 and polypropylene/polypropylene 1% maleic anhydride/Mg(OH) 2 composites were prepared containing 10% or 30% Mg(OH) 2 . The composites have a high Young's modulus (twice that of polypropylene) and comparable tensile strength but less ductility. EDX examination of the fractured composite surfaces suggested a homogeneous Mg(OH) 2 distribution for composites produced with the addition of polypropylene grafted with maleic anhydride. The polypropylene/Mg(OH) 2 composites showed good antibacterial activity. The polypropylene/ polypropylene 1% maleic anhydride/Mg(OH) 2 composites were less effective.

To improve fire retardant behavior of bio‐epoxy resin, composites were prepared with three fire retardants (FRs); ammonium polyphosphate, aluminum trihydrate, and magnesium hydroxide. Fractured surfaces of prepared composites were observed with the scanning electron microscope (SEM). Tensile strength and Charpy toughness were evaluated and analyzed statistically using analysis of variance (ANOVA). Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were used to determine the thermal stability. SEM analysis results revealed fractured surfaces were altered with addition of FRs. Adding FRs can be regarded as a decrease in tensile strength and toughness complemented by improved stiffness. ANOVA analysis showed FR/bio‐resin composites have a statistically significant loss in tensile strength, stiffness, elongation, and Charpy toughness. The DSC results showed the glass transition temperature was not affected significantly by adding FRs and ranged from 66 to 69 °C. TGA showed the initial, midway, and maximum decomposition temperatures for composites and their ability to form improved ash yields compared to pure resin. Aluminum trihydrate and Mg(OH)2 had higher T50 suggesting an increase in thermal stability compared to pure bio‐epoxy. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47398.

The effect of using a compatibilizer, such as maleic anhydride grafted polyethylene (PEgMA), on the flame retardancy and mechanical (tensile) properties of HDPE nanocomposites with silane modified Mg(OH)2 was studied. The silane modification of Mg(OH)2 was confirmed by FTIR. Filler dispersion was characterized by scanning electron microscopy in transmission mode (STEM) and the effect of filler on mechanical properties was also evaluated. The flame retardant properties were evaluated by flammability tests (Underwriters Laboratory – UL‐94) and cone calorimeter. The mechanism by which the use of PEgMA compatibilizer improves the flame retardancy of HDPE/Mg(OH)2 was studied. Through the simultaneous TGAIR analysis, it was found that when using PEgMA, the flame retardant properties of HDPE/Mg(OH)2 are modified, due to the generation of volatile compounds in the thermal decomposition.
