Viscoelastic polyurethane (VEPUR) foams with increased thermal resistance are presented in this article. VEPUR foams were manufactured with the use of various types of flame retardant additives and keratin fibers. The structure of the modified foams was determined by spectrophotometric-(FTIR), thermal-(DSC), and thermogravimetric (TGA) analyses as well as by scanning electron microscopy (SEM). We also assessed the fire resistance, hardness, and comfort coefficient (SAG factor). It was found that the use of keratin filler and flame retardant additives changed the foams’ structure and properties as well as their burning behavior. The highest fire resistance was achieved for foams containing keratin and expanding graphite, for which the reduction in heat release rate (HRR) compared to VEPUR foams reached 75%.

This article presents studies of fire resistance in the treatment of expanded vermiculite, which depends on the size of the dispersed particles and the orientation of the granules, their moisture and temperature. It has been studied that one of the interesting and important in practice properties of vermiculite is its ability to swell and turn into a lightweight effective material for imparting fire resistance. The properties and compositions of vermiculite from the Tebinbulak deposit are studied, from which a flame-retardant suspension is prepared for processing textile materials based on vermiculite dissolved in orthophosphoric acid and alkali in an aqueous medium. When modifying materials with developed flame-retardant suspensions, it is possible to obtain fire-resistant textile materials that meet the requirements of GOST for fire resistance, smoke generation and other physical and mechanical properties.

Protective Performance

To develop industrial and firefighter thermal protection cloth, 12 base fabrics were prepared from a combination of several types of sample, and their thermal performances were evaluated. Thermal performance comprises flame retardant capability, radiant protective performance, and thermal protective performance. Thermal protection performance has been assessed in accordance with ISO 15025, ISO 9151, ISO 6942, and ISO 17492. In this study, however, thermal protective performance was assessed only in accordance with ISO 15025. The results showed that Samples 1-6 satisfied the fire resistance criteria, whereas Samples 7-12 did not satisfy the fire resistance criteria. Additional thermal performance tests need to be conducted in follow-up studies.

Poly Acrylamide

Poly(acrylamide-acrylic acid) (P(AM-co-AA)) was synthesized via the copolymerization of acrylamide and acrylic acid and well characterized by Fourier transform infrared spectroscopy. Afterward, the obtained P(AM-co-AA) was blended with flame retardants to prepare transparent flame-retardant hydrogel applied in the fireproof glass. The influence of poly(acrylamide-acrylic acid) on fire resistance and anti-aging properties of the transparent flame-retardant hydrogels were studied by assorted analysis methods. The optical transparency analysis shows that the light transmittance of the transparent flame-retardant hydrogel gradually decreases with the decreasing mass ratio of acrylamide to acrylic acid in P(AM-co-AA). Heat insulation testing shows that the heat insulation performance of fireproof glass applying the transparent flame-retardant hydrogel firstly decreases and then increases with decreasing mass ratio of acrylamide to acrylic acid in P(AM-co-AA). When the mass ratio of acrylamide to acrylic acid is 1:2, the obtained P(AM-co-AA) endows the resulting flame-retardant hydrogel applied in fireproof glass with the lowest light transmittance of 81.3% and lowest backside temperature of 131.4 °C at 60 min among the samples, which is attributed to the formation of a more dense and expanded char to prevent the heat transfer during combustion, as supported by the digital photos of char residues. The results of TG analysis indicate that P(AM-co-AA) imparts high thermal stability to the resulting hydrogels due to the hydrogen bonds between carboxyl and amide groups. The accelerated aging test shows that the transparent flame-retardant hydrogel containing P(AM-co-AA) is less affected by aging conditions. Especially, when the mass ratio of acrylamide to acrylic acid in P(AM-co-AA) is 4:1, the resulting transparent flame-retardant hydrogel shows a light transmittance of 82.9% and backside temperature of 173.1 °C at 60 min after 7 aging cycles, exhibiting the best comprehensive properties among the samples.
