Method & Evidence

AimTo evaluate the effectiveness of magnesium hydroxide (Mg(OH)2) and aluminum hydroxide (Al(OH)3) as non-toxic flame-retardant additives in acrylic-based coatings and to determine the optimal formulation for fire protection.
MethodExperimental testing and comparative analysis
ProcedureAcrylic polymer emulsions were modified with low percentages (2 wt.%) of Mg(OH)2 and Al(OH)3. Flame exposure tests were conducted for 15 and 30 seconds on coated samples. The extent of combustion damage was analyzed to correlate flame-retardant properties with the choice and particle size of the hydroxide additive.

Variables

IVType and particle size of hydroxide additive (Mg(OH)2, Al(OH)3, small vs. large particle size).
DVFlame-retardant behavior (measured by flame stability and thermal insulation, assessed via damage area analysis after flame exposure).
CVAcrylic polymer emulsion type, additive concentration (wt.%), flame exposure time (15 s, 30 s).
