“…Our multi-year experimental research dedicated to the protection and cellulose tissue from fire showed, that the process of impregnation of cellulose-containing raw materials includes the stage of filling the capillary space of sapwood and also the pores of cellular walls at heat-ing, when the solution gets to the amorphous part and then to crystal part of polysaccharides, and the interaction of impregnating solution with polysaccharides and lignin. [12][13][14][15][16] The incorporation of impregnating solution into the structure of the wood substantially changes the process of degradation of the polymer, properties and the yield of obtained carbon residue. Derivatograms of the wood impregnated with different compositions were recorded in order to study the process of carbonization and pore-forming of carbon, the correlations between the compositions of inhibitors, change of the weight at heating, preservation of different elements and the yield of carbon residue were established.…”

Single-stage process of obtaining active carbon by thermal processing of plant raw materials (mixture of different types of wood sawdust), impregnated with the mixture of phosphoric acid, urea and nitric acid salts has been developed. Active influence of impregnates on the process of carbonization and formation of carbon residue has been formed. It is established that carbon residue obtained in the interval of heating 20 • C-(500 • C-700 • C), possesses high sorption activity to the vapors of organic compounds and has ion-exchange capacity. It has been showed that the value of carton residue depending on the impregnate used in the wood increases compared to the yield of non-treated initial raw materials by 3.1 times at 600 • C and by 4.2 times at 700 • C.

“…In recent years, the basic understanding and development of essential knowledge have led to the combined use of phosphorus compounds with minerals, giving rise to flame-retardant coatings to be used for wood applications [28][29][30][31][32]. The use of flame retardants leads to the alteration of polymers' decomposition route aiming at the reduction of combustible volatiles' concentration by promoting char formation.…”

Novel Hybrid Organic–Inorganic Polymeric Coatings Containing Phosphonium or Acidic Groups for Improving Flame Retardancy of Wood

et al. 2023

Flame-retardant polymeric coatings with high limiting oxygen index (LOI) were prepared by combining inorganic mineral huntite (H5) and polymeric additives synthesized in the present work into a polymeric formulation. In order to improve the dispersion of the Mg- (and Ca)-based H5 particles, additives containing phosphonium and acidic groups were employed to homogenize the inorganic fillers into the polymer matrix. Specific blend combinations of the commercial matrix Ecrovin® LV 340 eco with huntite and the additives poly(benzyltriphenylphosphonium-co-4-styrene sulfonic acid) P(SSH-co-SSBTPB60) and poly(hexadecyltributylphosphonium-co-4-styrene sulfonic acid) P(SSH-co-SSTBHDPB80), combining acidic and phosphonium groups, led to LOI values of 34.5% and 33.5%, respectively. The novel flame-retardant polymeric coatings inhibited the combustion of the coated wood substrates, which is attributed to the combination of acidic groups that promote the dispersion of inorganic filler in the polymer matrix and phosphonium groups that support the increase in LOI values.
