“…Flame retardant coating is an application of lignin coating that is recently getting attention in the nonwoven and textile fields (Reti et al 2009;Jiao and Wu 2013;Łukawski et al 2020). An intumescent flame-retardant (IFR) coating protects the fabrics by forming an intumescent charred layer, and this layer prevents the heat transfer and combustion of nonwoven fabrics (Fu et al 2017;Lopez-Cuesta 2017).…”

While lignin has been gaining wide research interest for a variety of applications across many industries, relatively little work has been published on its applications in nonwovens. Consequently, this article offers an overview of the underlying principles and both the present and future applications of lignin within the nonwoven industry. Due to the distinct structure of lignin, processing, fiber production, composites with polymers, dye dispersant, and fire-retardant applications are all unique opportunities for lignin application in nonwovens discussed in this review. Conventional nonwoven processing techniques, such as electrospinning, have been reported to successfully produce lignin-based nonwovens, specifically lignin/polymer composite nonwovens. This account points to pivotal polymer matrix/lignin composite compatibility issues that define various processing technologies. However, lignin use is not limited to incorporation within nonwoven fibers mats and is currently used in dye dispersion with the potential of phase out petroleum-based dye dispersants. Finally, the high phenolic content of lignin endows it with fire-retardant and antimicrobial properties, among others, that present additional opportunities for lignin in the nonwoven industry. Throughout this review, an effort is made to outline the advantages and challenges of using lignin as a green and sustainable ingredient for the production of nonwoven materials.

Intumescent paints are specially formulated reactive coatings designed to swell or expand into thick foamed char upon exposure to heat, protecting the substrates against fire by insulation and providing a protective barrier to heat and mass transfer. The present review describes some recent work related to the development of intumescent fire protective coating that is suitable for the protection of non-flammable substrates, such as structural steel, against fire. The key factors in the intumescent formulations, binders, flame retardants, fillers, modifiers, nano-dimensional additives, and weathering that affect the properties and performance of intumescent coatings are described. An attempt has also been made to describe different fire protection methods and testing characterizations involved in the fire protection of structural steel using intumescent fire-resistant coatings.

“…In recent years, with the lack of petroleum resources and the enhancement of people’s awareness of environmental protection, biomass carbon sources have gradually emerged [16,17,18]. Therefore, we reported the preparation of flame-retardant microspheres (K-CM/APP) by covering APP with the k-carrageenan (KC) wall.…”

In this article, the intumescent flame-retardant microsphere (KC-IFR) was prepared by inverse emulsion polymerizations, with the use of k-carrageenan (KC) as carbon source, ammonium polyphosphate (APP) as acid source, and melamine (MEL) as gas source. Meanwhile, benzoic acid functionalized graphene (BFG) was synthetized as a synergist. A “four-source flame-retardant system” (KC-IFR/BFG) was constructed with KC-IFR and BFG. KC-IFR/BFG was blended with waterborne epoxy resin (EP) to prepare flame-retardant coatings. The effects of different ratios of KC-IFR and BFG on the flame-retardant properties of EP were investigated. The results showed that the limiting oxygen index (LOI) values increased from 19.7% for the waterborne epoxy resin to 28.7% for the EP1 with 20 wt% KC-IFR. The addition of BFG further improved the LOI values of the composites. The LOI value reached 29.8% for the EP5 sample with 18 wt% KC-IFR and 2 wt% BFG and meanwhile, UL-94 test reached the V-0 level. In addition, the peak heat release (pHRR) and smoke release rate (SPR) of EP5 decreased by 63.5% and 65.4% comparing with EP0, respectively. This indicated the good flame-retardant and smoke suppression property of EP composites coating.
