Bio-humectants based flame retardants for impregnation and coatings treatment of wood substrates – BIOSUOJA
Introduction
Wood's appeal as a construction material faces significant challenges, particularly regarding fire safety compliance. Regulations in numerous countries, including the European Union, have been established to ensure the safety of living environments where wood is used in construction. Addressing these challenges necessitates precise engineering solutions. Due to its inherent combustibility and flammability, wood requires treatment with flame-retardant materials to meet fire resistance standards for building safety. Traditionally, halogens like bromine and chlorine have been utilized for this purpose, despite their environmental toxicity and persistence. Consequently, non-halogen, biobased flame retardants are increasingly replacing halogen-containing counterparts to mitigate environmental harm. One sustainable and effective approach involves applying coatings containing biobased flame-retardant materials to render wood resistant to fire.
Objectives
- Formulation of bio-based coating materials that will demonstrate superior fire retardancy.
- To enhance the fire protection of materials E.g., wood and textile
Approach
- Chemical modification of bio-materials such as cellulose, lignin and other bio-polymer for fire retardance.
- The combination of bio-materials with fire-retardant additives.
- The incorporation of fire-retardant additives into commercial paint.

Conclusions
Biomaterials possess inherent flammability, posing challenges in developing biobased flame retardants. We have created an intumescent flame-retardant coating utilizing biomaterials enriched with phosphorus and nitrogen. This innovation significantly extends the time of ignition compared to commercial fire-retardant paints, while also substantially reducing both total heat release and peak heat release rate.
