Description

Fireproof flame-retardant composite floor

Technical Field

The utility model relates to a floor, in particular to laminate flooring with fire prevention fire-retardant characteristic.

Background

A fire of a railway subway and light rail vehicle is a disaster burning phenomenon which loses control in time and space. In light rail vehicles, solid materials are generally used for generating fire, and at present, wood flame-retardant plywood which consists of a surface layer and a core material is adopted as a floor of a light rail train. The surface layer is a birch and cork combined laminated board, and the core material is a sound insulation layer. The disadvantages are that: although the floor is subjected to special fireproof treatment, the floor is made of wood materials and can be quickly burnt when a fire disaster happens. Due to the addition of a large amount of flame retardant, the flame-retardant plywood can release toxic gases such as CO, HCN, NO2 and the like during burning, and is very harmful to human bodies. The adhesive used by the plywood is urea-formaldehyde resin, unreacted formaldehyde or formaldehyde which does not correspondingly form methylene in the adhesive is remained in the board layer, and free formaldehyde can be continuously diffused out in the storage and use processes of the plywood, so that the plywood has great harm to human bodies.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1 to 3, the fire-retardant composite floor provided by this embodiment includes a plurality of floor units, and the entire floor is formed by splicing the plurality of floor units.

The structure of each floor unit is the same, the floor unit comprises an outer base plate 1 with a cavity 2, the section of the outer base plate 1 is rectangular, and a fireproof and flame-retardant core material 3 is arranged in the cavity 2. In this embodiment, install a plurality of fossil fragments 8 in outer base plate 1, a plurality of fossil fragments 8 extend along floor length direction, and a plurality of fossil fragments 8 parallel arrangement each other, and the last inner wall of fossil fragments 8 and outer base plate 1 and lower inner wall are connected through the welded mode, separate into a plurality of spaces that extend along length direction with the cavity in outer base plate 1, all install core 3 in every space. Outer base plate 1 adopts the aluminium alloy or forms by aluminum plate concatenation welding, and fossil fragments 8 adopt foamed aluminum plate or aluminum plate, when guaranteeing floor intensity, are favorable to alleviateing the weight on floor.

In this embodiment, the core material 3 includes, in order from top to bottom, a foaming layer 4, a charring core layer 5 and an inorganic plate layer 6, and more preferably, a metal layer 7 is further disposed between the charring core layer 5 and the inorganic plate layer 6, wherein the foaming layer 4 is made of a PVC wood-plastic base material, and the metal layer 7 is made of a foamed aluminum plate or an aluminum plate.
