COMPARATIVE ANALYSIS OF FIRE PROTECTION CHARACTERISTICS OF TWO TYPES OF COATINGS

Materials from natural raw materials are always of great demand in the sphere of construction, both large-sized structures and the smallest decoration elements. Regardless of the area of use, wood needs to be processed, whether it is protection from excessive heat and possible sources of ignition, protection from biological influences, including natural conditions, or processing in order to give an object aesthetic features, or create interior compositions. Each type of coating – enamel or paint – has a number of individual characteristics. The aim of research is to identify the relationship between the special fire-retardant paint «Pirex», which provides the first fire protection group, and general-purpose wood paint «Luxart» without a certificate of belonging to one or another fire group security. Referring to State Standard R 53292-2009, which is the basis of the research, wood samples were treated with potential fire protection, after which conclusions were presented on the effectiveness of all tests. In addition to examining the difference between fire retardant paint and general purpose paint, the effect of applied agent layers on the fire retardant properties of wood was investigated. The results of the studies carried out allow us to draw conclusions about each method of applying paint and to identify correlation dependences for each paint on the number of coating layers.
