Hierarchical Lamellar Aluminophosphate Materials with Porosity as Ecofriendly Inorganic Adhesive for Wood-Based Boards

Abstract: Aluminophosphate inorganic adhesive (APIA), as a binder for wood-based boards (WBB), is synthesized between Al­(OH)3 and H3PO4 in solution with hydrothermal treatment in this study. Aluminophosphate compounds with hierarchical lamellar structure are observed on the fibers’ surface. The rheological behavior analysis reveals that the viscosity of APIA varied with its P/Al molar ratio [n­(P)/n­(Al)]. P–O–Al bridges are formed during the hydrothermal treatment of the APIA. The amounts of hydrogen bonds are formed … Show more

“…2(c) is the reason why oligomers of aluminophosphates condensed to form orbicular structures and then break to form catenulate structures at this temperature range. 13,34 A sharp peak appeared around 165 C on the PAP-3% curve in Fig. 2(c).…”

“…As a result, P-O-C and Al-O-C covalent bonds may form between PVA and AP. 13,37 The reaction process could be described as presented in Fig. 3 To further investigate the framework of PAP, the 27 Al MAS NMR and 31 P MAS NMR spectra of PAP are presented in Fig.…”

“…Figure 4b shows the digital images of the bamboo bundles after the stain and mildew infections with Al-P at a mass ratio of 1 to 1. The Al-P sol could build a threedimension structure on the surface of bamboo bundles (Chen et al 2018). They form a protective film over its surface to strengthen the natural defense mechanism against damage from mildew.…”

“…Inorganic binders have lots of advantages, such as high temperature resistance, excellent durability, and little harm to the environment [ 20 , 21 ]. For example, aluminophosphate, an inorganic binder, synthesized by the reaction between Al(OH) 3 and H 3 PO 4 , could be taken as adhesives and mixed with wood fibers to prepare wood-based boards, and the wood-based boards show good porosity and high strength, due to the addition of the aluminophosphate [ 22 ]. The phosphate-based adhesive could be also used to improve the strength of concrete [ 23 , 24 ].…”
