Background
The plywood is made up by cutting wood segment into single boards or cutting wood Fang Bao into Cheng Baomu, and then using adhesive to glue them to form three-layer or multi-layer plate material, usually using odd-layer single boards, and making the fibre directions of adjacent layers of single boards mutually perpendicular and glue them together. The plywood is one of common materials for furniture, is one of three artificial boards, and can also be used as a material for aircrafts, ships, trains, automobiles, buildings, packaging boxes and the like. A group of veneers are usually glued in mutually perpendicular groups according to the grain direction of the adjacent layers, and the surface plates and the inner plates are usually symmetrically arranged on two sides of the central layer or the core plate.
The existing plywood has the following defects in the manufacturing and using processes:
1) The traditional plywood is only subjected to flame retardant treatment by adopting fireproof paint, so that the flame retardant effect is poor, and the market demand cannot be met;
2) The traditional plywood is formed by using thin wood for gluing, so that the strength is low, the service life of the plywood is low, and the plywood is easy to damage during transportation;
3) The traditional plywood is adhered and connected by using a large amount of adhesive, so that harmful substances in the plywood are seriously volatilized;
4) The traditional plywood is not provided with a sound insulation material, so that the sound insulation effect of the plywood is poor, and the plywood is generally only used for building base materials;
5) The conventional plywood has rough upper and lower surfaces, resulting in poor decorative properties.
Disclosure of Invention
The utility model aims to solve the defects and provide a flame-retardant plywood.
The object of the utility model is achieved by:
the utility model provides a but fire-retardant plywood, includes the core, and the upper and lower two sides of core all have set gradually waterproof layer, fire prevention dope layer, acoustic celotex board and PLASTIC LAMINATED outward along the core, and waterproof layer, fire prevention dope layer, acoustic celotex board and PLASTIC LAMINATED all are fixed through gluing, are equipped with first steel sheet between fire prevention dope layer and the acoustic celotex board, fix through gluing between first steel sheet and fire prevention dope layer and the acoustic celotex board, are equipped with the second steel sheet between acoustic celotex board and the fire-retardant board, fix through gluing between second steel sheet and acoustic celotex board and the fire-retardant board.
In the above description, the core plate, the fireproof plate, the soundproof plate, the first steel sheet, and the second steel sheet are preferably the same in length-width dimension.
In the above description, as a preferable mode, the soundproof plate is provided with a cavity, and the inside of the cavity is filled with fireproof soundproof cotton.
In the above description, as a preferable scheme, the outer side surfaces of the core plate, the sound insulation plate and the fireproof plate are provided with edge seals, and the edge seals are in adhesive connection with the outer side surfaces of the core plate, the sound insulation plate and the fireproof plate.
The beneficial effects of the utility model are as follows: the upper and lower two sides of core all have set gradually waterproof layer, fire prevention dope layer, acoustic celotex board and PLASTIC LAMINATED outward along the core, be equipped with first steel sheet between fire prevention dope layer and the acoustic celotex board, be equipped with the second steel sheet between acoustic celotex board and the PLASTIC LAMINATED, the structure of traditional plywood has been changed in the setting of steel sheet, effectively improve the intensity of plywood, avoid the plywood to appear breaking phenomenon in the use, the PLASTIC LAMINATED replaces traditional plywood outermost veneer, the surface of PLASTIC LAMINATED is smooth, can effectively improve the decorative of plywood, in addition, the PLASTIC LAMINATED has excellent fire resistance, the PLASTIC LAMINATED forms the fire-retardant inoxidizing coating of multichannel through cooperation fire prevention dope layer and steel sheet, can effectively improve the security that the plywood was used.
Drawings
FIG. 1 is a schematic perspective view of an embodiment of the present utility model;
FIG. 2 is a top view of an embodiment of the present utility model;
FIG. 3 is a cross-sectional view of A-A of FIG. 2;
in the figure, the core plate is 1-, the waterproof layer is 2-, the fireproof coating layer is 3-, the first steel sheet is 4-, the sound insulation board is 5-, the fireproof sound insulation cotton is 6-, the second steel sheet is 7-, the fireproof board is 8-and the edge sealing is 9-.
Detailed Description
The utility model is described in further detail below with reference to the drawings and the detailed description.
1-3, a fire-retardant plywood of its implementation, including core 1, core 1 has all set gradually waterproof layer 2, fire prevention dope layer 3, acoustic celotex board 5 and PLASTIC LAMINATED 8 along core 1 outwards in proper order on the upper and lower two sides of core 1, waterproof layer 2, fire prevention dope layer 3, acoustic celotex board 5 and PLASTIC LAMINATED 8 all fix through gluing, PLASTIC LAMINATED 8 replaces traditional plywood outermost veneer, the surface of PLASTIC LAMINATED 8 is smooth, can effectively improve the decorative of plywood, in addition, PLASTIC LAMINATED 8 has excellent fire-retardant properties, PLASTIC LAMINATED 8 can effectively improve the security that the plywood used through cooperation fire prevention dope layer 3 and steel sheet.
