Description
Technical field
The utility model relates to cable laying mounting technique fields, and in particular to the fire barrier in a kind of cable trough.
Background technique
With the development of urbanization process, it is mainly used to want the cable of equipment power supply increasingly common, in order to protect cable
Outside being not directly exposed to, cable trough is usually set, for placing cable.It is general in cable trough to place high-voltage electricity simultaneously in practice
Cable, low-voltage cable and communicaton and signal cable, cable usually use the flammable plastic wraps such as polyethylene, polyvinyl chloride, cross 280 DEG C
After will fuel, occur electrical fire calamity;High-tension cable, low-voltage cable are separately prevented, signal cable generation interference close to each other requires
Each cable is opened in barrier.
Existing fire barrier plays the role of certain fire-retardant fireproof in practice, but since intensity is low, prevents flame
Penetration capacity is insufficient, and heat insulation is not good enough;Toughness is very poor, is actually being laid in operation, it is obvious that chance turning has interface gap
The problem of, flameproof effect reduces, and installing and dismounting is cumbersome, needs to expend a large amount of manpower and material resources;It can not be by different function
Cable is effectively spaced apart, and is resulted in greater loss once breaking down and being easy to bring disaster to adjacent cable.
Summary of the invention
Aiming at the deficiencies in the prior art, the utility model provides a kind of good flame retardation effect, toughness strong anti-fire screen
Plate.
For above-mentioned purpose, technical solutions of the utility model are as follows:
A kind of fire barrier in cable trough, it is fire-retardant resistance to including polyurethane hard bubble sandwiched layer, the high tenacity for wrapping up laminboard layer
There is corrosion-inhibiting coating on high-temperature material and one or more layers outermost fire resistance fibre cloth, fire resistance fibre cloth surface.
The polyurethane hard bubble sandwiched layer is with a thickness of 1.5cm.
The high tenacity flame-resistant high-temperature-resistant material is fire-resistant engineering plastics, with a thickness of 1cm.
The fire resistance fibre cloth is ceramic fiber cloth.
The corrosion-inhibiting coating is epoxy-phenol resin paint, and thickness is not less than 1mm.
The flame retardant property of the fire barrier is not less than V0 grades.
It is made up of above-mentioned fire barrier material for the fire barrier in cable trough, with the connection being mounted in cable trough
Support assorted uses.
Further, the fire barrier is in U-shape, and the bottom edge of U-shaped fire barrier is connected with connecting bracket.
Further, the connecting bracket is integral type modular rack and can mutually connect side by side, the fire prevention
Partition is arranged using modular construction and with the guide rail card slot matching in the connecting bracket.
The utility model has the advantages that the utility model is pressed from both sides using ceramic fiber cloth, high tenacity flame-resistant high-temperature-resistant material and hard polyurethane foam
The compoiste adhering stratiform structure that sandwich layer is constituted,
(1) ceramic fiber cloth is stablized with high temeperature chemistry property, 1200 DEG C or more the sustainable uses of high temperature, thermal coefficient pole
Small, acid and alkali-resistance excellent anti-corrosion performance, aluminum-resistant zinc etc. is confused molten metal attack ability, has anti-oxidant, high-intensitive, high tenacity etc.
Advantage.
(2) polyurethane hard bubble sandwiched layer is used, the laminboard layer thermal coefficient is low, fire prevention, fire-retardant, high temperature resistant, its softening
Point can reach 250 DEG C or more, even if laminboard layer can also form carbon in its foam surface in burning, can be effectively prevented fire
Flame sprawling.
(3) using epoxy-phenol resin paint adhesive force is strong, salt spray resistance, alkali resistance is excellent, matching is good, corrosion resistance is strong.
Cable bearer and fire barrier become batch production product, avoid conventional on-site cutting and welding and install, letter
Change site workload, improves construction efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, the polyurethane hard bubble sandwiched layer of 1-, 2- fire-resistant engineering plastics, 3- ceramic fiber cloth, 4- epoxy-phenol resin paint.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Refering to Figure 1, being the preferred embodiment of the fire barrier in a kind of cable trough of the utility model, including poly- ammonia
The hard bubble sandwiched layer 1 of ester, the fire-resistant engineering plastics 2 for wrapping up laminboard layer 1 and outermost three layers of ceramic fiber cloth 3, ceramic fiber cloth 3
There is epoxy-phenol resin paint 4 on surface.
Various sizes can be made in above-mentioned fire barrier according to standard, and thickness is within 3cm, wherein polyurethane hard bubble sandwiched layer
1 with a thickness of 1.5cm, fire-resistant engineering plastics 2 with a thickness of 1cm, the thickness of epoxy-phenol resin paint is not less than 1mm.
It when concrete application, is made up of above-mentioned fire barrier material for the fire barrier in cable trough, and is mounted on electricity
Connecting bracket in cable slot is used cooperatively, and fire barrier is in U-shape, and the bottom edge of U-shaped fire barrier is connected with connecting bracket, described
