Abstract

Purpose.  Development of fire protection composition and study of its properties: definition of fire protection group of the proposed coating.  Methodology.  In the course of the research, an analytical review of the main groups  of fire retardants, which increase the fire resistance of wooden construction constructions, gave an assessment of their technical characteristics, as well as in accordance with DSTU B V.1.1-4-98  "Fire  protection.  Building  constructions.  Test  methods  for  fire  resistance.  General  requirements  "defines  the  fire-protective properties of the developed fire protection coating. Findings. The authors developed a composition of flame retardant coating that forms on the  surface,  which  "protects"  a  thin  non-transparent  layer  that  prevents  inflammation  and  spread  of  flame  on  a  wooden  structure.  The selection of composition of fire protection composition was carried out according to the scheme "compound  -  the additive that is flowing  -the filler". The basis of the coating is liquid glass, because it has such positive characteristics as accessibility, due to the manifestation of liquid glass adhesive properties  -  the ability to spontaneous hardening with the formation of artificial silica. An increase in the content of fillers can increase the use interval of the composition to 900-9200С, and the maximum temperature at which provides the swelling of the coating  540-6800С.  According  to  studies,  the  highest  fire-retardant  coating  efficiency  is  achieved  with  content  in  the  composition  of asbestos-cement waste from 15.0 to 22.5%, aluminum-calcium slag from 7.5 to 10.0%. An increase in the content of fillers and technical drill for a rational area reduces the heat-shielding ability of the coating and reduces the fire-retardant effectiveness of the coating. Adding to the flame retardant composition sulfite-alcoholic membrane greatly improves the adhesion of the coating from the protected surface, which also  affects  the  fire-protective  ability  of  the  coating,  it  grows  to  76.0-81.0  minutes.  Originality.  Taking  into  account  the  theoretical preconditions, the choice of output components for a new fire protection composition has been carried out.  Practical value.  A new nonflammable spillway structure is developed,  which allows the transfer of combustible  materials into a  group of heavier  and increase  fire resistance of building structures. On the developed fireproof composition the Ukrainian patent for utility model was obtained.
