Abstract

The possibility and expediency of evaluating the properties of the flame retardant coatings has been exemplified by the chlorine-containing flame-retardant composition according to the criteria quantitatively characterizing the process of coating intumescence, i.e. intumescence ratio, mass variation, density and porosity of the foamed coke formed as a result of heating the samples. The degree of intumescence and changing in mass of the coating samples have been determined according to the conventional techniques; density and porosity variations of coke have been measured by the computation based on the experiment data. The curves of dependence between the intumescence parameters of coating and the temperature have been derived. The results of the investigation showed that these parameters may be applied as the evaluation criteria for comprising the formulae and further optimization of coatings properties designed to protect building constructions in conditions of extreme heat exposure.
