Due to the hydrophilic nature of the aluminophosphate (AP) adhesives, their application in the wood-based board (WBB) industries is rarely considered. Herein, the AP adhesives with reduced graphene oxide (AP@rGO) were developed for the construction of hydrophobic surface, mainly for the improvement of the water resistance of AP-based WBB interface as well as their mechanical properties and fire resistance. Results indicated that there is an excellent interfacial adhesion between the AP@rGO and fibers, making the APW@rGO achieved a high dry bonding strength of 2.77 MPa. Utilizing the advantages of rGO network with outstanding water resistance, the WBB engineered the comparable wet bonding strength as high as 1.65 MPa, meeting the minimum requirement of the plywood standard stated in GB/T9846.3–2004. Also, AP@rGO exhibited an excellent fire resistance properties and smoke suppression ability. Benefiting from these remarkable results, the AP@rGO could be broadly developed for practical applications in related wood-based products.

用还原的氧化石墨烯在磷酸铝胶粘剂中构建疏水界面,以改善人造板的性能

由于铝磷酸盐(AP)胶粘剂的亲水性,很少考虑将其用于木板(WBB)行业。在本文中,具有降低的氧化石墨烯(AP @该AP粘合剂ř GO)为疏水性表面的结构被开发,主要用于基于AP-WBB接口以及它们的机械性能和耐火性的耐水性的提高。结果表明,存在AP @之间的优异界面粘合性- [R GO和纤维,使得APW @ - [R GO达到2.77兆帕的高干燥的接合强度。利用r的优势GO防水网具有出色的防水性,WBB设计的可比湿粘合强度高达1.65 MPa,符合GB / T9846.3–2004中胶合板标准的最低要求。此外,AP @ r GO还具有出色的耐火性能和抑烟能力。得益于这些非凡的成果,AP @ r GO可以广泛开发用于相关木基产品的实际应用。
