Abstract


Purpose.The aim of this work is to develop a flame retardant and a study of its efficiency: the definition of a group of fireproof efficiency of the tested coatings. Methods. An analytical review of the major groups of flame retardants, increasing the fire resistance of wooden structures, an assessment of their technical characteristics, as well as in accordance with GOST 16363-98 "means flame retardants for wood. Methods for determination of flame retardant properties "defined flame retardant properties developed fire-retardant coating. Results. The authors have developed a flame retardant composition of the intumescent agent (herein-after - OZVS), which forms a "protected" the surface of a thin opaque layer, which prevents the spread of fire and flames on a wooden structure. Selection of the composition was carried out on a "binder - intumescent additive - filler". The basis taken coatings waterglass, since it has such positive characteristics as accessibility, associated with the appearance of liquid glass binding properties - the ability to selfhardening to form artificial silicate stone. Introduction into the liquid glass components such as perlite, graphite epoxy, due to their positive characteristics with respect to the action of high temperature yielded a new flame retardant. The average weight loss of value of 6 samples was 6.875%. OZVS layer thickness is less than 1 mm. According to GOST 16363-98 [2] developed OZVS provides group I of fire-proof efficiency for wood, because the loss of a secure timber in the mass of the test conditions, not more than 9%. Scientific novelty. Given the choice of theoretical assumptions held initial components for the new flame retardant. Practical meaningfulness. It has developed a new non-combustible intumescent composition that allows to convert combustible material to the group and to increase slow-fire building designs.
