The waterproof fireproofing composite floor board
Technical field
The utility model relates to a kind of composite floor board, and feature is a kind of composite floor board with waterproof fireproofing function.
Background technology
Huge numbers of families have been come into as a kind of home decoration material in the floor, but wood flooring exists waterproof and dampproof wear-resisting and fire safety problem.Present wood flooring generally is to be compounded with magnesium oxide layer or melamine layer on wood plies, utilizes the water-fast and abrasion resistance of magnesia and melamine to reach the waterproof and the wear-resisting purpose of floor surface.In order to prevent the moisture on ground, also need below compoiste wood floor, lay moisture sealer.Like this, not only construction is inconvenient, and is difficult to guarantee that its seam crossing can not see through moisture, and in addition, floor gap is managed the bad water immersion underfloor that also can make on the floor everywhere, and layer of wood is made moist.In addition, because timber is inflammable, so also there is fire safety problem in wood flooring.
The utility model content
The purpose of this utility model is to provide a kind of composite floor board with waterproof fireproofing function, and this floor is wear-resisting, waterproof, protection against the tide, fire prevention, has solved the problems referred to above that existing wood flooring exists.
In order to achieve the above object, the waterproof fireproofing composite floor board that the utility model relates to is the sandwich construction that bonds together, and is followed successively by by inorganic matter substratum for waterproofing, substrate layer, inorganic matter water-proof antifriction layer and fireprotection layer.
Above-mentioned inorganic matter substratum for waterproofing and inorganic water-proof wearing layer are magnesia or calcium silicates layer, play wear-resisting and waterproof and dampproof effect.
Above-mentioned substrate layer can be plank layer or cement flaggy.The fireprotection layer that plays anti-fire action is the lino that sticks on the inorganic water-proof wearing layer.
The waterproof fireproofing composite floor board that the utility model provides because on substrate layer and below compound magnesia or calcium silicates layer with wear-resisting and water resistance, make this composite floor board have wear-resisting, waterproof, moistureproof advantage, owing to nonflammable lino is arranged, above it so also have fireproof performance.And this underfloor need not lay moistureproof bed course, so installation is convenient.
Description of drawings
Fig. 1 is a waterproof fireproofing composite floor board structure chart of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, waterproof fireproofing composite floor board of the present utility model is made of four-layer structure, bottom magnesia inorganic layer 1 for having waterproof and dampproof performance, it on it plank basic unit 2, above the plank basic unit 2 is the magnesium oxide layer inorganic layer 3 of waterproof antiwear, be fire prevention lino layer 4 topmost, this four-layer structure bonds together.
Above-mentioned magnesia inorganic layer 1 and waterproof antiwear magnesium oxide layer 3 also can replace with the calcium silicates layer, and its plank layer also can be cement wood layer.
This composite floor board is owing to all have a waterproof inorganic layer up and down, thus have fabulous waterproof moisture-proof effect, and fire prevention, easy construction.
