Wooden materials have been extensively used for
furniture, outdoor and indoor cladding, buildings, terrace, fence, garden
furniture and interior decoration and to decorate the roofline of houses.
However, wood which is used outdoors or in areas exposed to moisture needs to
be protected against wood-destroying organisms and to be shielded from water,
marine pests, fungi, fire and weather conditions. Untreated wood materials have
no resistance to the spread of fire and many buildings which constructed from wood
based materials needs to fire resistance. It is possible that the wooden
material ensures very durable and resistant against physical effects by surface
applications such as wood preservative paint and acrylic resin-based varnish.
The application of fire retardant chemicals can also provide to satisfy
regulatory requirements for wood products.

In this study, titanium dioxide and antimony trioxide
were applied on pine (Pinus sylvestris L.)
solid wood material to determine durability of reaction to fire using by oxygen
index test technique (ASTM D 2863-6) and real fire test. These chemicals were
added to the wood preservative paint which is a commercial product as
concentrations of 2%, 5% and 10% for titanium dioxide and 2% and 5% for
antimony trioxide. The effects on colour change of their surfaces, brightness
and surface roughness measurements, water absorption and thickness swelling of
this wood material were also carried out. The results obtained were analysed
statistically and compared with the related standards. Addition of these
chemicals to used wood preservative paint had a positive impact on the fire
properties of the pine wooden surface.
