A TECHNOLOGY OF A NEW, EFFECTIVE INTUMESCENT FIRE RETARDANT SYSTEM, WHICH CONTAINS MODIFIERS IN NANO SCALE HAS BEEN DEVELOPED FOR PROTECTION OF WOOD AND LIGNOCELLULOSIC COMPOSITES AGAINST FIRE. IT IS A FORM OF EFFECTIVE FIRE PROTECTION COATING FOR INTERIOR WOOD AND WOOD DERIVATIVES SURFACES. THE FIRE RETARDANT VARNISH PROVIDES COATINGS, WHICH SWELL AND INCREASE THEIR VOLUME AS THE RESULT OF HEAT OR FLAME AND CREATE A THICK CARBONIZED AND POROUS LAYER. THIS PERFECTLY ISOLATES THE COVERED MATERIAL FROM THE EXCESSIVE RISE OF TEMPERATURE AND OXYGEN PENETRATION AND THUS PROTECTING FLAMMABLE MATERIALS AGAINST THERMAL DECOMPOSITION AND IN CONSEQUENCE AGAINST LOSS OF MECHANICAL PROPERTIES.

1. Application of modifiers in form of nanoparticles significantly improves the fire retardancy and thermal insulation effectiveness of the system. High degree of particle dispersion causes changes in decomposition processes as well as combustion of coating. The time of carbonized layer formation is reduced, also the structure of carbon skeleton improved towards small-cell structure (this allows reducing the amount of system used and by this reducing the costs of protection).

2. It does not change a natural appearance of protected material thanks to transparency of a coating. It does not contain organic solvents and it is water - based. It was developed by waste - free technology.

3. Intumescent system effectively protects wood and different wood derivatives (plywood, particleboard, high and low density fiberboard) in non-flammable degree, at only 250-350 g/m2 of the system applied.

4. The fire retardant and coating formed by this system does not emit toxic substances and poses no threat to the environment nor to human health. This allows for the system application in places permanently occupied by people.

It can be used in different branches of economy, especially in construction industry (roofs, flat roofs, struts, beams, supporting structures, suspended ceilings, etc. in housing, public buildings, warehouses and on factory sites) and transportation. For decorative finishing of materials fire retardant intumescent base coat requires applying transparent, top coat in order to protect it against moisture. An intumescent fire retardant system has been implemented in Poland, and has patent protection in the USA, China and Hong Kong.
