Problems solved by technology
[0003] 1. It takes a long time for veneer immersion in conventional production, and the flame retardant is recycled after immersion, which will cause waste of flame retardant in the whole process, thus increasing the overall manufacturing cost;
[0004] 2. The plywood used in conventional production is usually assembled in the whole layer, and the flame retardant part required by the flame retardant plywood is only the surface layer and corner position of the board, thus causing serious waste

Embodiment Construction
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0027] see Figure 1 to Figure 3 , the present invention provides a technical solution: a method for preparing flame-retardant and fire-resistant multi-layer plywood. In the preparation method, a liquid immersion device for flame-retardant and fire-resistant multi-layer plywood is used. The device includes a liquid immersion table 1, a liquid immersion The liquid immersion tank 2 provided on the upper end of the table 1 is hinged with the platen set 3 on the s...

The invention discloses a method for preparing flame-retardant and fire-resistant multi-layer plywood. In the preparation method, a liquid-immersing device for flame-retardant and fire-resistant multi-layer plywood is used. The pressure plate group hinged on the side of the liquid tank and the immersion tank, the invention discloses a preparation method of flame-retardant and fire-proof multi-layer plywood, the method includes the following steps: Step 1: veneer sorting; Step 2: Equipment cleaning; Step 3 Step 4: vacuuming; Step 5: liquid injection; Step 6, heat preservation; Step 7, separation and depressurization; Step 8: glue coating and assembly; Step 9: pressing plate forming; , improve the efficiency of immersion liquid, and reduce the loss of flame retardant, thus saving production cost; through the sandwich arrangement of flame retardant board, flame retardant frame and core board, the immersion area required for the single board is greatly increased Reduced, thus greatly saving production costs.
Description
technical field [0001] The invention relates to the technical field of plywood preparation, in particular to a method for preparing flame-retardant and fireproof multi-layer plywood. Background technique [0002] Plywood is a three-layer or multi-layer board-shaped material made of wood sections that are peeled into veneers or sliced into thin wood, and then glued with adhesives. Plywood is one of the commonly used materials for furniture, and it is the three largest wood-based panels One, plywood can improve the utilization rate of wood, which is a main way to save wood. In order to further improve the performance of the plywood, the veneer of the plywood is subjected to flame-retardant treatment, so that the plywood has flame-retardant and fire-resistant properties, and this plywood is a flame-retardant and fire-resistant plywood. The main preparation method of flame-retardant plywood in the prior art is through flame-retardant treatment of the veneer, and then each ply...
