Photoluminescent Material for Protective and Decorative Coatings of Building Constructions and Elements of Evacuation Systems

The results of experimental studies of photometric properties of photoluminescent material (PLM) for protective and decorative coatings and elements of evacuation systems obtained on the basis of a structured aqueous solution of high-modulus potassium silicate and photoluminophore (PL) are presented. Electron microscopic, energy dispersive X-ray and granulometric analysis of the structure, elemental chemical composition and size distribution of PL particles were determined. A mathematical model of the dependence of the initial luminance of the photoluminescent material on the mass concentration of the PL, the color temperature of the artificial light source and the illumination time is constructed by the method of orthogonal central composite planning. According to the criteria of the Student and Fischer, an assessment of the statistical significance and adequacy of the mathematical model was performed, which allows determining the rational values of prescription and technical factors in the manufacture and operation of PLM with a luminescence brightness of up to 1800 mcd/m² after 10 min and up to 600 mcd/m² after 60 min after the cessation of illumination, with an afterglow duration of more than 10 h.
