DAP - 12-18

boric acid - 4-8

promoterami organic material - 2-4

water - the rest

An example implementation of the invention, a composition is prepared by mixing diammoniumphosphate, boric acid, and water, followed by the introduction prosteradlo organic material - decabromodiphenylethane and put on the protected surface by conventional spray. Test for Flammability, smoke generation and toxicity carried out in accordance with GOST 12.1.044-89 "Pozarovzryvobezopasnost substances and materials. The range of indicators and methods of their determination".

Options% ratio of components in the composition and its properties are shown in table the crystals of synthetic and cellulose fibers, as well as for fire protection of wood. Moreover, in addition to the resulting protection of fire-retardant materials they have reduced toxicity.
