The study of efficiency of fire-proof coatings for foam polystyrene

Foam polystyrene is a heat-insulating polymer material which is widely used in construction of economy class low-rise buildings (summer and garden cottages, pavilions, makeshift barracks, etc.). A disadvantage of foam polystyrene is its high flammability. Previously conducted research showed that foam polystyrene is an easily flammable building material. Therefore, development of fire-proof coatings which provide a decrease of foam polystyrene’s ignitable characteristics, preservation of its heat-insulating properties and which do not significantly increase the material’s cost is still a topical issue. The method of surface application of fire-proof coatings, which is the most cheap and available method, is considered in the article as one of the methods for ignitability reduction. Non-flammable fire-resistant coatings for foam polystyrene are studied in the article. The more efficient fire-proof compositions are selected in the result of experiments.
