The invention discloses a method for manufacturing an indoor environmentally-friendly
flame retardant blockboard. The method comprises the following steps of: manufacturing
brush wood and small-
diameter wood into rectangular battens with the same thickness; arraying and bonding the rectangular battens to form coreboards through
extrusion and surface sanding; obtaining poplar laminated
veneer lumbers and fully immersing the poplar laminated
veneer lumbers in the solution of water base
flame retardant agents at the concentration of 20 percent for
flame retardant treatment;
drying the treated poplar laminated
veneer lumbers and gluing on one side; covering the glued poplar laminated veneer lumbers on two side surfaces of the coreboard, and then performing cold pressing,
hot pressing and sanding treatment; gluing and bonding poplar rotary
cut skins on the two side surfaces of the sanded plates, and then performing
ageing, the cold pressing, repairing, the
hot pressing and
polishing; and finally trimming the four sides of the polished plates and repairing cracks caused by trimming to obtain the finished flame retardant blockboard. The blockboard manufactured by the method has a good flame retardant property and a small number of influences on texture properties; moreover, the method has the advantages of simplicity, easy application, short production period, high efficiency and low cost.
