COMPARATIVE EVALUATION OF FIRE-PROTECTIVE PROPERTIES OF PHOSPHORUS-CONTAINING FIRE RETARDANTS BASED ON POLYETHYLENETEREPHTHALATE AMINOLYSIS PRODUCTS

The work purpose — receiving and studying of properties and fireproof efficiency fire retardants for wood on the basis of products aminolysis PETF. To compare received results on fireproof efficiency with let out now the industry Ammafon-1. The fire-protective was received from products aminolysis by PETF aliphatic amines. As an aliphatic amines used monoethanolamine (FRC-1), diethanolamine (FRC-2), polyethylenepolyamine systems (FRC-3). In the article the physico-chemical properties of synthesized FRC are given. The preliminary estimate of efficiency of fireproof structures on a method “a fire pipe” showed that application of developed by nitrogenphosphorus-containing fire retardant composition leads to decrease in loss of weight of wood samples when burning. For the purpose of confirmation of preliminary researches of fireproof efficiency of the new structures, carried out the express — the method, carried out fire retardant composition tests on a basis ethanolamines on OTM type installation. The carried-out researches showed that received fireproof structures FRC-1 and FRC-2 at an expense more 100 g
m2 treat the first group of fireproof efficiency.
