Dual functions of bioinspired, water-based, reusable composite as a highly efficient flame retardant and strong adhesive

Synthesis of an efficient phosphorus and triazine ring-containing reactive flame retardant for epoxy resin

“…This was where the P-O-C group in the HOMP broke apart first potentially yielded PO, an irregular substance capable of quenching and terminating a burning. Also, the phosphate derivatives originating from HOMP thermal depolymerization could bond with epoxy resin degradation and facilitate carbon deposition (Knights et al ., 2022; Bhakare et al ., 2023).…”

“…Same time, several peaks around 1,260 cm −1 should be associated with phosphorus groups. Especially combined with the analysis of TGA (Figure 2) and Cone Calorimeter (Figure 3), we believed the decomposition products of HOMP could directly inhibit the combustion of these gaseous combustibles (Knights et al ., 2022; Bhakare et al ., 2023).…”

Renewable micro hydroxyapatite (mHA) extracted from animal bones, and fabricated mHA-Jute-vinyl ester bio-composite as an intumescent green flame retardant material

“…B. et al prepared a sustainable bio-based, reusable, formaldehyde-free strong P@TS/AJ adhesive which exhibited excellent flame-retardancy properties. 34 Bearing in mind the prominent advantages of vinyl ester resin (VER), such as outstanding mechanical properties, cohesiveness, and excellent heat and corrosion resistance, it has been comprehensively exploited in many industrial applications, including composites, adhesives and printed circuit board coatings. Recently, Xu Z. et al have reported a bridge-linked phosphorus-containing flame retardant of 15 wt% PBDOO in VER with a UL-94 V-0 rating and a high LOI value of 31.5%.…”

Biocomposite Foams with Multimodal Cellular Structures Based on Cork Granulates and Microwave Processed Egg White Proteins

“…The possibility of reusing cork by-products for applications in the construction industry has been widely studied [3]. Due to their homogeneous closed cellular structure, they are used for thermal and acoustic insulation in building construction [4][5][6][7] and for the preparation of lightweight wood-based sandwich structures [8]. The mechanical and thermal properties of cork panels depend upon the characteristics of the granulated cork (gradation, density, size, and grain size distribution) and on the type of the binder used, usually based on urethane, melamine, or phenolic resins.…”
