Description
Technical field
This utility model is related to a kind of inorganic cut-off fire prevention extruded sheet.
Background technology
XPS (extruded polystyrene) extruded sheet is exactly extrusion moulding type polystyrene heat insulating board.It is with poly-
Styrene resin is that raw material adds other supplementary materials and poly- inclusion, mixes injecting catalyst simultaneously by heating, then extrusion molding
Extrusion molding and the rigid foam plate that manufactures.Its scientific name is extrusion molding polystyrene polyfoam for heat insulation (abbreviation XPS),
XPS extruded sheets have perfect closed honeycomb structure, and this structure allows XPS extruded sheets that there is extremely low water absorption (hardly to inhale
Water), low thermal conductivity coefficient, high pressure resistance, ageing resistance (normal using almost without degradation and decomposition phenomenon).
An existing utility model, its Publication No.：204645286 U of CN, the utility model disclose a kind of XPS extrusion moldings
Plate, the upper and lower surface of extruded sheet is fluted and concave point.The XPS extrusion moldings plate surface of the utility model produces concave-convex effect, favourable viscous
Patch, which, is carried in more than 0.25MPa significantly with the tensile bond strength of adhesive and decorative mortar, water-fast and freeze-thawing resistant intensity
The high cohesion of system, increases reliability.But its fire protecting performance grade highest can only be improved by above-mentioned XPS extruded sheets
To B1 levels.

Description of the drawings
Fig. 1 is the structural representation of fire prevention isolation channel of the present utility model；
Fig. 2 is the structural representation of fireproof agent of the present utility model；
Fig. 3 is another kind of structural representation of this utility model fire prevention isolation channel.
Specific embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in Figure 1 and Figure 2, a kind of inorganic cut-off fire prevention extruded sheet, which includes plate body 1, and the two sides of plate body 1 has a plurality of
Crisscross fire prevention isolation channel 2, preferably：Isolation channel 2 of preventing fires per bar is square groove or wedge-shaped slot.It is a plurality of fire prevention isolation channel 2 it
Between spacing be 16 to 19 centimetres, specifically, it is a plurality of fire prevention isolation channel 2 between spacing can for 17 centimetres, 17.8 centimetres,
18.5 centimetres, 18.6 centimetres etc., preferably in 17.5 cms；Per bar, the depth of fire prevention isolation channel 2 is 3 to 4 centimetres, fire prevention
Fireproof agent 3 is provided with isolation channel 2, best fireproof agent 3 is gypsum mortar, HBCD or cement mortar；The fireproof agent
Concordant with plate body 1 to become an overall structure, the overall structure is coated with the cement layer of 4-6cm.
Further：Plate body 1 is set to cuboid structure, its a length of 90 to 130cm, a width of 30 to 70cm, it is thick for 3 to
