“…Most coatings consist of a combination of film-forming agents and flame retardants (including acid, carbon, and gas sources) [ 28 , 29 ]. Some biomass materials, such as nitrogen [ 30 , 31 ], phosphorus, and sulfur have excellent carbon-forming properties, which can be used in the production and research of intumescent flame retardants [ 32 ]. These biomasses employed in flame retardants can be classified into three categories based on their elemental composition: biomass-based charring agents [ 33 ], biomass-based acid sources [ 34 ], and biomass-based foaming agents [ 35 ].…”

Research and Application of Biomass-Based Wood Flame Retardants: A Review

Wood is widely used as a construction material due to its many advantages, such as good mechanical properties, low production costs, and renewability. However, its flammability limits its use in construction. To solve the problem of wood flammability, the most common method to improve the fire safety of wood is to modify the wood by deep impregnation or surface coating with flame retardants. Therefore, many researchers have found that environmentally friendly and low-cost biomass materials can be used as a source of green flame retardants. Two aspects of biomass-based intumescent flame retardants are summarized in this paper. On the one hand, biomass is used as one of the three sources or as a flame-retardant synergist in combination with other flame retardants, which are called composite biomass intumescent flame retardants. On the other hand, biomass is used alone as a feedstock to produce all-biomass intumescent flame retardants. In addition, the potential of biomass-based materials as an environmentally friendly and low-cost FR source to produce high-performance biomass-based flame retardants with improved technology was also discussed in detail. The development of biomass-based intumescent flame retardants represents a viable and promising approach for the efficient and environmentally friendly production of biomass-based flame retardants.

“…Compared with the above flame retardants, biomass flame retardants have the advantages of renewable, environmentally friendly, low price and vast source. [22][23][24] Among them, Phytic acid (PA), a phosphorous flame retardant of biomass, is mainly stored in plant tissues with a phosphorus content of up to 28%, 25 which is widely used in the field of flame retardancy. Zhang et al 26 prepared hemp fiber reinforced composites for automobile parts by modifying hemp fiber (HF-P) with phytic acid.…”

Ramie composites have been widely used in automobiles, daily necessities, aerospace, ships, cruise lines, etc., but their flame retardant properties are relatively poor, which is difficult to meet the flame retardant performance requirements of composites for rail transit. In order to improve the properties of ramie reinforced composites, flame retardant treatment is necessary. In this paper, phosphorus flame retardant phytic acid (PA) was used to modify ramie fabric, and then the composites were prepared. The flame retardancy and mechanical properties of ramie reinforced composites were investigated. It was found that the flame retardancy of ramie composites was improved after flame retardant modification with phytic acid, but the mechanical properties were decreased. In order to improve the mechanical properties of PA ramie composites, two kinds of layered PA ramie/glass fiber hybrid composites were prepared by replacing part of ramie with glass fiber. The results show that the addition of glass fiber can improve the mechanical properties and flame retardancy of composites.

“…With the concept of green environmental protection gradually becoming the consensus in the world, non-toxic, halogen-free, and DOI: 10.1002/mame.202200586 environmentally friendly flame retardant systems have attracted wide attention. [1,2] Currently, flame retardants in common use usually include intumescent flame retardants (e.g., ammonium polyphosphate and expandable graphite), [3][4][5] bio-based flame retardants (e.g., chitosan, lignin, alginate, and cyclodextrin), [6][7][8] and inorganic flame retardants (e.g., zinc borate and aluminum hydroxide). [9,10] For instance, a biomass melamine phytate has been used as a flame retardant, showing good compatibility with the rigid polyurethane foam (RPUF) matrix, and inhibiting the release of smoke (e.g., aromatic compounds, cyanide and CO), toxic gases and combustible gases (e.g., hydrocarbons and esters).…”

Iron tailings (ITS), as solid decay absolved afterward beneficiation, are adverse to the environment. ITS to prepare zinc‐containing mesoporous silicate (MAO‐Zn) by a calcination‐crystallization method are used. An admixture of ammonium polyphosphate (APP) and MAO‐Zn can solve the problem of poor flame retardancy in rigid polyurethane foam (RPUF), giving them higher thermal stability and lower heat release. The total heat release rate and smoke factor values exhibited by RPUF‐3 are 24.52 MJ m−2 and 234.29 MW m−2 respectively, a decrease of 38.45% and 29.60% respectively compared to pure RPUF. Lower combustible and toxic gas release intensities are in RPUF‐3. Meanwhile, RPUF‐3 possesses enhanced compactness char residue with higher graphitization degree, endowing RPUF‐3 with excellent fire observed performance. This work demonstrates the potential of ITS in the fire retardancy field.
