An inorganic adhesive mix consisting of MgO, MgCl2, Na2SiO3, Na3PO4 was used to prepare mineral bound particleboard (mbPB) without formaldehyde emission and with excellent fire retardant and smoke suppression properties. The mechanical properties, interior microstructure, fire retardancy and smoke suppression behavior of the mbPB was investigated based on scanning electron microscopy (SEM) and cone calorimetric observations. The results showed that the presence of massive hydrates of the inorganic adhesive covers the mbPB particles, which are r...
