“…As a result, DAL could undergo intermolecular chemical cross-linking with the unsaturated silicon monomer in the SAE-based composite coating through ion interaction and hydrogen bonding. This cross-linking process promotes the formation of amorphous Si−P−C sols, 59 effectively inhibiting heat transfer and flame propagation.…”

Through the substitution reaction between 9,10dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and sodium lignosulfonate (LS), a novel phosphorus-containing sodium lignosulfonate (DAL) was successfully synthesized via the solvothermal method and used as a multifunctional flame retardant to prepare a novel silicone-acrylic emulsion (SAE) composite Si− P−C coating. The structure of DAL was determined by X-ray diffraction (XRD), attenuated total reflection infrared spectroscopy (ATR-FTIR), X-ray photoelectron spectroscopy (XPS), and nuclear magnetic resonance (solid-state 13 C NMR and 31 P NMR). The results demonstrated that incorporating an appropriate dosage of DAL (0.9 g, 1.5 wt %) into SAE-based composite coatings enhances flame retardancy and reduces heat release and smoke production during burning. The peak heat release rate (p-HRR) decreases from 236.7 to 120.3 kW•m −2 , total smoke production (TSP) decreases by 71.1%, and the flame-retardant index increases from 1.00 to 4.58. Meanwhile, the coating is transformed into a dense and nonflammable vitreous polyphosphate barrier layer during the firing process to prevent heat or mass transfer. Furthermore, the pyrolysis kinetics identify that the 3D Z−L−T model governs the coatings' pyrolysis, and the appropriate DAL makes the pyrolysis E α climb from 300.98 to 331.30 kJ•mol −1 at 358−439 °C. Hence, this study presents a new synthesis method of multifunctional flame retardant DAL, studies the excellent properties and cross-linking mechanism of DAL-doped SAEcomposite Si−P−C coatings, and explores a halogen-free, low-carbon, and clean eco-technology strategy.

“…One major route for silica production is to hydrolyze silicate and condense to precipitate at controlled pH and temperature. This bottom-up procedure in a solution state allows the preparation of nanosilica for rubber reinforcement and also opens a door for the in situ incorporation of lignin . He et al. , studied the assembling process of lignin and silica through a coprecipitation method.…”

“…This bottom-up procedure in a solution state allows the preparation of nanosilica for rubber reinforcement and also opens a door for the in situ incorporation of lignin. 60 He et al 61,62 studied the assembling process of lignin and silica through a coprecipitation method. Silica precipitates at a pH of ∼9, and acts as the template to regulate the precipitation of lignin via the hydrogen-bonding interaction, as the pH is lowered by adding acid.…”

The biomass lignin is the only large-volume renewable feedstock that is composed of aromatics but has been largely underutilized and is sought for valorization as a value-added material. Recent research has highlighted lignin as a promising alternative to traditional petrol-based reinforcements and functional additives for rubber composites. This review summarized the recent advances in the functionalization of lignin for a variety of rubber composites, as well as the compounding techniques for effectively dispersing lignin within the rubber matrix. Significant progress has been achieved in the development of high-performance and advanced functional rubber/lignin composites through carefully designing the structure of lignin-based additives and the optimization of interfacial morphologies. This Review discussed the effect of lignin on composite properties, including mechanical reinforcement, dynamic properties, antiaging performance, and oil resistance, and also the advanced stimuli-responsive performance in detail. A critical analysis for the future development of rubber/lignin composites is presented as concluding remarks.
