Abstract
The utility model discloses a halogen-free environment-friendly non-inflammable light fire-resistant plate for the cable fire protection. A middle layer is formed by repeatedly compositing and pressing a halogen-free inorganic bonding layer and a light thermal insulation material; and a glass fiber cloth layer or an aluminium foil layer is respectively bonded at the upper and the lower surface layers of the middle layer. The fire-resistant plate disclosed by the utility model has the characteristics that magnesium oxide-magnesium sulfate is adopted as the inorganic bonding layer of the composite plate and no halogen is contained and has the advantages of incapability of damp getting or halogenation in dark and moist weather, combustion and fire resistance, environmental friendliness, no toxicity, high strength, long life and the like.
Description
Technical field
The utility model relates to a kind of cable fire-proof flame-retarded light refractory slab, particularly a kind of halogen-free environment-friendly type cable fire-proof flame-retarded light refractory slab and products thereof.
Background technology
The cable fire-proof sheet material of in the market extensive use is to be the inorganic clad plate of binding agent with magnesia-magnesium chloride mostly, has following shortcoming in the application:
1. material contains a large amount of halogens in forming, and can decompose during burning to produce a large amount of irritating hydrogen chloride pernicious gases, causes secondary disaster, and especially the nuclear power station place does not allow to contain halogen especially in using material, has limited use;
2. during wet weather, the halogen of getting damp phenomenon is arranged, metal is corrosive;
3. after the moisture absorption, mechanical strength obviously descends, and affects service life;
4. fire protecting performance is stable not, often has the fire of chance to fire phenomenon, causes fire prevention to be lost efficacy;
5. meet fire and can decompose efflorescence and lose intensity, refer to touch and namely wear.
Therefore, must the cable fire-proof of the Halogen of present use be improved with inorganic clad plate.
The utility model content
Technical problem to be solved in the utility model is that a kind of not halogen-containing halogen-free environment-friendly type cable fire-proof flame-retarded light refractory slab and products thereof will be provided.
In order to solve above technical problem, the utility model provides a kind of halogen-free environment-friendly type cable fire-proof flame-retarded light refractory slab, Halogen inorganic bond layer and light heat-insulating material repeatedly compound suppressing consist of the intermediate layer, at the upper and lower top layer in intermediate layer each adhesive glass fiber layer of cloth or aluminium foil layer.
Described Halogen inorganic bond layer is magnesium oxide-magnesium sulfate inorganic bond layer.
A kind of fire resistant air-duct of utilizing above-mentioned halogen-free environment-friendly type cable fire-proof to make with the flame-retarded light refractory slab, the sheet material of this airduct be Halogen inorganic bond layer and light heat-insulating material repeatedly compound suppressing consist of the intermediate layer, at the upper and lower top layer in intermediate layer each adhesive glass fiber layer of cloth or aluminium foil layer.Described Halogen inorganic bond layer is magnesium oxide-magnesium sulfate inorganic bond layer.
A kind of fire-resistant groove box that utilizes above-mentioned halogen-free environment-friendly type cable fire-proof to make with the flame-retarded light refractory slab, the sheet material of this airduct be Halogen inorganic bond layer and light heat-insulating material repeatedly compound suppressing consist of the intermediate layer, at the upper and lower top layer in intermediate layer each adhesive glass fiber layer of cloth or aluminium foil layer.Described Halogen inorganic bond layer is magnesium oxide-magnesium sulfate inorganic bond layer.
Beneficial functional of the present utility model is:
