Abstract


In this research, the effects of boric acid (H3BO3) solution on the combustion properties of water based varnish was investigated. For this purpose, water-based varnish which was modified with 5% boric acid at varied amount (10%, 20%, and 30%) was applied on the experiment samples made from scots pine (Pinus sylvestris L.) and beech (Fagus orientalis L.). Afterwards, the combustion properties of the water based varnish was determined according to ASTM-E 69 standard principles.

 During combustion tests, released amount of oxygen (%), carbon monoxide (ppm), nitrogen oxide (ppm) gases, mass loss of the samples (%) and combustion temperature values are determinate. According to the research outcome, when increase the boric acid value in the water based varnish the resistance properties against to fire increases. In addition it may also be suggested that, in the selection of the furniture and decoration parts likely to be exposed to higher temperatures, beech wood is better than pine wood.
