“…So, it is advantageous for boron-based flame retardants to endow strong charring ability and physical barrier against fire with the treated paper. Moreover, formation of protective layer effectively inhibited the This finding agrees with the other reports [51][52][53][54][55]. Furthermore, the boron-containing layer could effectively the underlying fiber from further combustion, producing the strong the self-extinguishing action of the treated sample (Fig.…”

Paper packaging materials like cardboards are widely used to protect archives which are a major kind of cultural relics. Unfortunately, paper is a combustible material, and thus exploring environment-friendly flame retardant for paper-based archive packaging material plays an important role. Herein, boric acid, borax and disodium octaborate are used to modify the craft paper-based packaging materials for archive conservation to improve fire safety. The modified craft paper exhibits much higher flame retardancy than the pristine one dose based on vertical burning tests, without much influence on mechanical properties such as tensile strength and elongation at break. Thermogravimetric analysis (TGA), scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS) reveal that porous glass structure is formed during the combustion, because thermal decomposition of boric acid, borax and disodium octaborate will produce porous glassy matter as B 2 O 3 . The porous glass covers the paper surface as an insulating layer which retards the further pyrolysis and combustion, resulting in a denser carbon layer. Our study provides a robust way to reduce the fire hazard of the archive packaging material by applying environment-friendly boron-based fire retardants.

“…A modified solution containing boric acid and borax was used to improve the durability and flame retardancy of wood or wood products, and some of the physical and mechanical properties of wood could be improved by varying the proportion of boric acid and borax and the treatment temperatures (Ustaomer and Usta 2012;Palanti et al 2012;Zhang et al 2015;Kol et al 2017;Wu et al 2021). Although boric acid and borax have been used in wood modification for many years, there are only a few reports on its application for improving the flame retardancy of bamboo (Yu et al 2017;Li et al 2020a). To better understand the impact of boric acid and borax on the performance of bamboo, various physical properties, mechanical properties, and decay resistance of bamboo were analyzed in this study.…”

As a renewable biomaterial, bamboo has been widely used in construction and indoor decoration. While the application of bamboo is limited by its low decay resistance and flame retardancy, the combination of modification with boric acid and borax has been found to be effective for improving bamboo flame retardant. In this study, the decay resistance, mechanical properties, and physical properties of bamboo, both before and after treated being with boric acid and borax (in a 1 to 2 ratio), were analyzed to better utilize the modification solution for bamboo. The results showed that in comparison to the untreated bamboo, the treated bamboo had a strong decay resistance, i.e., greater than 80% resistance effectiveness improvement. In addition, the decay resistance and compression strength of the samples showed a considerable increase, i.e., 21%, after the modification. However, the physical properties e.g., the weight gain, equilibrium moisture content, and dimensional stability and bending properties of the bamboo were less affected by the modification method, which could be improved via the combination with another chemical modification agent.
