“…[ 26–28 ] However, the fire resistance of pristine starch materials is not high enough for practical requirements; it is usually necessary to combine starch with other flame retardants to meet the practical application via synergistic effects. [ 29,30 ] To promote the mechanical performance of starch aerogels and endow them fire‐resistance simultaneously, borax was adopted based on the following consideration.…”

To achieve ecofriendly aerogels with high mechanics and fire resistance, naturally‐occurring pea starch was employed as the major substrate, and starch‐based composite aerogels were fabricated by freeze–drying method. The corresponding hydrogels were obtained through successive gelatinization/dissolution of pea starch and polyvinyl alcohol (PVA), formation of precursor hydrogels via cyclic freeze–thawing, followed by treatment with borax aqueous solution. Borax treatment not only results in aerogels with high mechanics, but also endows the aerogels flame‐retardant property. The final aerogels show high compression‐resistance, with a maximum specific compressive modulus achieved at ~44 MPa and the yield strength 665 kPa, owing to the formation of a multi‐crosslinked hybrid network. The maximum limiting oxygen index (LOI) of the aerogels exceeds 34. The peak heat release rate, the heat release capacity, and the total heat release decrease 74.5%, 76.2%, and 73.8% after borax treatment. Moreover, the obtained aerogels demonstrate good thermal stability and thermal insulation. The good performance is conducive for practical application.

“…Another limitation of the aqueous solutions is their poor adherence to and a potential run-off from the vertical surfaces, which can be solved by adding thickening, or gel-forming, agents such as sodium bentonite, or starch, mixed with clays [11]. Starch was also selected as a main component of FR systems in several other studies due to its good adhesion to the wood surfaces [12][13][14][15][16][17]. In addition, starch is a bio-based polymeric component derived from renewable and widely available biomass resources; it can be easily and cheaply extracted from unwanted residues such as food or agricultural waste (e.g., potato peels or corn cobs) [18].…”

The present paper reports the preliminary results relating to the development, subsequent application, and testing of environmentally benign starch-based formulations for passive fire protection of wood substrates. This study evaluated the effectiveness of starch colloid coatings applied onto the wood surface with a view to improving its performance when exposed to the external heat flux (35 kW/m2) during cone calorimetric tests. The formulations were prepared from aqueous colloid solutions of either starch alone, or in combination with inorganic salts, such as: sodium carbonate, Na2CO3, potassium carbonate, K2CO3, and diammonium hydrogen phosphate, (NH4)2HPO4. The fire performance of Taeda pine wood samples, where their top surfaces were treated with these formulations, was compared with the control sample. The thermal and combustion characteristics of the tested samples were determined with the aid of thermo-gravimetric analysis (TGA), bomb and cone calorimetric techniques, and a steady state tube furnace coupled to an FT-IR spectrometer. A significant boost of fire protection was observed when starch formulations with added inorganic salts were applied onto the wood surfaces, compared with the control sample. For example, the presence of K2CO3 in starch colloid solutions resulted in a notable delay of the ignition and exhibited a reduction in the heat release parameters in comparison with the untreated wood substrate.
