Protection of Wood from Burning with Paints on Alkaline Aluminosilicates-Based

Abstract

The aim of the work was to determination the combustibility group of color fire retardant paints for wood. As a result of the fire tests, it was found that the developed compositions of fire-retardant mineral paints on an alkaline aluminosilicate binder in the (Na, K)2O-Al2O3-nSiO2-mH2O system are difficult to combustible and to flammable, and occupy a middle position between G1 and G2 in the combustibility group. As a result of the fire tests, the temperature of the flue gases did not exceed the critical value - above 260 [°C], the weight loss of the samples was in the range from 5.56 to 10.17 [%], and the burning rate did not exceed 0.0026 [kg/(m2s)]. Given the rather high margin of flue gas temperature, further fire tests are planned to be carried out according to EN 13823 in RICE Sweden.
