Preparation and Mechanical Properties of Foamed Cement Composite Boards Reinforcedwith Fire-retardant Medium Density Fiberboard
A composite board made with fire-retardant medium density fiberboard(FR-MDF) as face layer and foamed cement as core layer was prepared by the authors. The effects of overlayingtechnology and the FR-MDFlayer on mechanical properties of the composite board were evaluated. The results showed that: 1) When density of the core material was 0.38 g/cm3 and polyurethane foam adhesive consumption was 90 g/m2, the bonding strength of the composite board could meet the requirements of DB 21/T 2353-2014; 2) Overlaying with FR-MDF could improve the overall mechanical properties of the board, including edgewise compressive strength, flexural strength and impact strength.
