Preferably, the first middle plate and the second middle plate are symmetrically tiled up and down on the surface of the core plate, and the core plate is integrally coated by the first middle plate and the second middle plate, so that the structural stability of the core plate is greatly improved.

Preferably, the salt-resistant and corrosion-resistant layer is an alpha-methyl styrene coating, so that the salt corrosion resistance of the surface of the plywood is greatly improved, and the service life of the plywood is prolonged.

Preferably, the flame-retardant insulating layer is PUR heat insulation cotton, has good flame-retardant and heat-insulating properties, and can effectively avoid the condition that the plywood is burnt due to high temperature.

Preferably, the wear-resistant moisture-proof layer is a modified asphalt board, the high-strength polypropylene fiber base cloth is used as a carrier, asphalt permeates into all fine spaces of fibers, the wear resistance of the cement layer at the bottom of the house is improved, and moisture at the bottom is prevented from permeating into the plywood board.

Preferably, the cross-section of filling the groove is the U shape structure, be equipped with antibacterial filling layer in the filling groove, antibacterial filling layer is nanometer silver ion filling layer, has good antibiotic bacteriostatic ability, avoids the glued wood board to use the inside condition that produces the worm-eaten for a long time.

Compared with the prior art, the beneficial effects of the utility model are that:

through the salt-resistant layer structure that resists who sets up on the panel, avoid having the meal of salt nature at family's eating process and drop to the panel and cause the condition that the panel received salt erosion, through the fire-retardant insulating layer that sets up, can preset at family's house cement ground and lay the electric wire, effectively avoid the electric wire short circuit and cause the plywood to receive the condition of high temperature combustion.

In addition, through the antibacterial filling layer structure of the symmetrical formula that sets up, improved the holistic antibiotic antibacterial of plywood, avoid the plywood to use the inside condition that produces the worm-eaten for a long time, moreover, the wear-resisting dampproof course that sets up has improved the wear-resisting moisture resistance in bottom of plywood.

Drawings

FIG. 1 is a sectional view of the whole structure of the present invention;

fig. 2 illustrates the present invention.

In the figure: 1 core plate, 2 first middle plates, 3 second middle plates, 31 filling grooves, 32 bacteriostatic filling layers, 4 panels, 5 salt and corrosion resistant layers, 6 bottom plates, 7 flame-retardant insulating layers and 8 wear-resistant moisture-proof layers.

Detailed Description

Referring to fig. 1 and 2, a fireproof plywood comprises a core board 1, a first middle board 2 and a second middle board 3, the first middle board 2 and the second middle board 3 are respectively glued on the upper surface and the lower surface of the core board 1, a panel 4 is glued on the upper end of the first middle board 2, a salt corrosion resistant layer 5 is glued on the upper end surface of the panel 4, a bottom board 6 is glued on the lower end of the second middle board 3, a flame-retardant insulating layer 7 is glued on the lower end of the bottom board 6, the flame-retardant insulating layer 7 is PUR heat insulation cotton, a wear-resistant moisture-proof layer 8 is glued on the lower end surface of the flame-retardant insulating layer 7, the wear-resistant moisture-proof layer 8 is a modified asphalt board, the modified asphalt board takes high-strength polypropylene fiber base cloth as a carrier, asphalt permeates into all fine spaces of fibers, the wear resistance of a cement layer on the bottom of a house is improved, and moisture on the bottom is prevented from permeating into the plywood.
