摘要：Oriented strand board (OSB) is widely used due to its unique texture and bonding strength, making the study of transparent fireproof coatings that preserve its aesthetic qualities both theoretically and practically significant. The transparent properties of vinyl acetate-ethylene copolymer emulsion (VAE emulsion) after curing, combined with traditional intumescent flame retardants, enable effective flame retardation of OSB boards. Inspired by this, different metal synergistic components (diethyl aluminum hypophosphite and magnesium hydroxide; aluminum sulfate and magnesium sulfate) compounding intumescent flame retardants (IFR: ammonium polyphosphate, melamine and pentaerythritol) were incorporated to enhance the flame retardancy and smoke suppression of VAE emulsion coating. The results show that, compared to fire retardant coatings with only the addition of IFR, the incorporation of Si-Mg-Al (Na2OnSiO2/MgSO4/Al2(SO4)3) synergists resulted in an approximately 7.3% reduction in peak heat release rate and an approximately 31% reduction in peak smoke release rate. Additionally, the total smoke production per unit area also significantly decreased. This work presents a novel approach for producing intumescent fire retardant coatings with enhanced fire resistance and smoke suppression properties.
