In the realm of wood preservation and fire protection, a groundbreaking study led by Irina V. Stepina from the National Research Moscow State University of Civil Engineering has unveiled a significant advancement. Published in the journal ‘Нанотехнологии в строительстве’ (Nanotechnologies in Construction), the research explores the impact of substituting hydroxyl groups with phenyl radicals in boron-nitrogen compounds, revolutionizing the effectiveness of wood preservatives and flame retardants.
The study underscores the critical role of the substituent nature in boron compounds, demonstrating that phenyl-containing boron-nitrogen compounds exhibit superior biocidal activity, thermal stability, and fire protection at remarkably low concentrations. “The introduction of a phenyl radical into boron-nitrogen compounds sharply increases their effectiveness as antiseptics and flame retardants,” Stepina explains. This innovation allows for a fivefold reduction in working concentration without compromising protective properties, a boon for both economic and environmental sustainability.
The implications for the construction and energy sectors are profound. Traditional wood treatments often require high concentrations of chemicals, leading to increased costs and potential environmental impacts. The new findings suggest that phenylborate-based compositions can offer comprehensive protection for lignocellulosic materials while minimizing the impact on the natural structure of the wood. “Low concentrations of phenylborates (5–10%) reduce processing costs,” Stepina notes, highlighting the economic benefits of this approach.
The research employed thermal analysis, fire-retardant effectiveness evaluations, and fungus resistance tests on pine wood samples modified with boron compounds. The results were clear: boron compounds with a phenyl radical showed higher effectiveness against mold and wood-destroying fungi and provided superior fire protection compared to traditional boron-nitrogen compounds with three hydroxyl groups.
This study not only advances our understanding of wood modification but also paves the way for more sustainable and cost-effective solutions in the construction industry. As the demand for eco-friendly and durable building materials grows, the insights from this research could shape future developments in wood preservation and fire protection technologies. The findings suggest that phenylborate-based compositions are optimal for comprehensive protection of lignocellulosic materials, aligning with environmental requirements and offering a sustainable solution for the energy sector.
In summary, the research led by Irina V. Stepina represents a significant step forward in the field of wood modification. By demonstrating the enhanced effectiveness of phenyl-containing boron-nitrogen compounds, the study opens new avenues for innovation in wood preservation and fire protection, with far-reaching implications for the construction and energy industries.
