MODERN APPROACH TO THE PREVENTION OF COMBUSTION OF WOOD AND IT PRODUCTS

Abstract

The paper investigates the fire protection of cellulose-containing materials (wood, plywood, fiberboard) used at various facilities. The solutions are based on the development of the scientific basis for the fire and biological protection of these materials using salt flame retardants, a cationic polymer antiseptic, and polyampholytic silicone substances, namely the use of the fire and biological protection compound "DSA-1" in the surface impregnation of wood makes it fire and biological resistant. The use of the fire retardant mixture "DSA-2" for wood processing using the hot-cold bath impregnation method and plywood by autoclave method allows to obtain fire retardant materials with G2, B1, RP-1, D2, T2 indicators, as well as samples of fire retardant heat and sound insulation wood fiber boards, which are classified as refractory materials. From the fire safety point of view, this allows them to be used in construction, at facilities with a large number of people, on evacuation routes, for wall and ceiling decoration and for filling in suspended ceilings in corridors, halls and foyers, on railways, etc. Additional treatment of fire-retardant wood and plywood with Silol hydrophobization compound can extend its service life by more than 5 years and allow it to be used outside facilities.The results of thermal engineering tests of fireproof heat and sound insulation wood fiber boards showed that they meet the requirements in terms of thermal conductivity.
