Embodiment Construction

[0028] The preparation method of the indoor environment-friendly flame-retardant blockboard is realized by the following specific steps:

[0029] 1) Saw the twig wood and small-diameter wood, and process them into rectangular wood strips with the same thickness. Dry the rectangular wood strips to a moisture content of 18% to 22%, and dry them at 60-80°C to control the moisture content at 16 % or less; then glue the rectangular wooden strips, and then use the rectangular iron frame as the mold, fully arrange and fill the rectangular wooden strips after gluing into the rectangular iron frame, under the pressure of 1.5MPa, the rectangular iron frame The wooden strips are hot-pressed on four sides and extruded into a semi-finished core board; then the semi-finished core board is scraped with putty to find unevenness, and then dried, and the surface of the semi-finished core board is sanded after the putty is dried to make the above-mentioned core board 3, such as figure 1 As show...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of blockboard preparation, in particular to a method for preparing an indoor environment-friendly flame-retardant blockboard. Background technique [0002] Blockboard has been widely used in interior decoration and high-end furniture production due to its advantages of light weight, high strength, good thermal insulation, beautiful texture, easy processing, and low energy consumption. However, due to the flammability of the blockboard, it is easy to cause the spread of flames in actual use, which has great potential safety hazards. Although the blockboard produced by some manufacturers has certain fireproof performance, its application range in the field of decoration has been greatly limited because some products have changed the texture performance of the blockboard; some products have complicated processing technology and equipment investment. Large, long production cycle, leading to soaring product cost...
