摘要

A new eco-friendly strategy to develop highly transparent fire-resistant coatings with intumescent three-source integration is proposed. Once exposed to fire

this coating can respond quickly and puff to form a stable foam-like insulation layer

making it a potential application for protecting wooden materials

particularly on ancient buildings and precious furniture.

Abstract

Wood

a readily available and sustainable natural resource

has found widespread use in construction and furniture. However

its inherent flammability poses a potential fire risk. Although intumescent fire-retardant coatings effectively mitigate this risk

achieving high transparency in such coatings presents a significant challenge. In our approach

we employed a cross-linked network of phytic acid anion and

-[3-(trimethoxysilyl) propyl

]

-trimethylammonium cation to create a transparent "three-in-one" intumescent coating. The collaborative P/N/Si flame-retardant effect markedly improved the intumescent char-forming capability

preventing the wood from rapid decomposition. This resulted in a substantial reduction in heat release (13.9% decrease in THR) and an increased limiting oxygen index (LOI) value of 35.5%. Crucially

the high transparency of the coating ensured minimal impact on the wood's appearance

allowing the natural wood grains to remain clearly visible. This innovative approach provides a straightforward method for developing transparent intumescent flame-retardant coatings suitable for wooden substrates. The potential applications extend to preserving ancient buildings and heritage conservation efforts.
