Description

Fireproof heat insulation plate

Technical Field

The utility model relates to a fire prevention building materials field, more specifically says, it relates to a fire prevention heat insulating board.

Background

When a fire disaster occurs, many people do not enter a relatively safe smokeless or low-temperature place in time to wait for rescue, and are fumigated or killed by high temperature in the first time of the fire disaster, so that the fire disaster is particularly dangerous in a high-rise area, and the escape probability is low. In the prior art, although the fireproof safety door or the partition wall made of fireproof materials is used for blocking open fire and heat radiation for a short time, the fireproof safety door or the partition wall is difficult to resist high temperature of a fire scene for a long time, so once a fire occurs, the time for people to escape is still short.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model aims to provide a fireproof heat insulation board has better separation high temperature's effect.

In order to achieve the above purpose, the utility model provides the following technical scheme:

a fireproof heat insulation plate comprises an inner plate, an inner fireproof layer, a fireproof cotton layer, an outer fireproof layer and a steel plate which are sequentially arranged; the steel sheet is provided with the one-level exhaust hole of equipartition, outer flame retardant coating is provided with the second grade exhaust hole of equipartition, the one-level exhaust hole with the second grade exhaust hole does not communicate with each other.

By the arrangement, the steel plate positioned on the surface can bear the high temperature within one thousand degrees and provides structural support for the fireproof heat insulation plate; the three fireproof structure layers in the fireproof heat insulation plate can effectively separate open fire and heat radiation, so that one side of the inner plate is not influenced by high temperature; the secondary vent holes are arranged to disperse heat accumulated in the outer fireproof layer through a gap between the outer fireproof layer and the steel plate and discharge the heat through the primary vent holes in the steel plate; thereby further slowing down the overheating of the plate and improving the barrier effect on high temperature.

Further setting: and a flame-retardant coating is coated on the surface of the steel plate.

So set up, establish fire-retardant layer through adding, can play the guard action to the steel sheet surface, delay the high temperature to the destruction time of steel sheet.

Further setting: the primary vent hole penetrates through the flame-retardant coating.

So set up to avoid the one-level exhaust hole to be blocked, influence the exhaust radiating effect.

Further setting: the aperture of the primary vent hole is not less than 1 mm, and the interval of the holes is between 20 mm and 30 mm.

Further setting: the aperture of the secondary vent hole is not less than 1 mm, and the interval of the holes is between 20 mm and 30 mm.

Further setting: the outer fire-proof layer and the inner fire-proof layer are both aluminum silicate ceramic fiberboard layers.

So set up, aluminium silicate ceramic fiber board layer has good heat-resisting effect, with the bonding back of asbestos layer, can keep comparatively lasting fire-retardant thermal-insulated effect.

To sum up, the utility model has the advantages of it is following:

1. the fireproof heat insulation plate has a simple structure, is easy to manufacture, and has good heat insulation and flame retardant effects;

2. the fireproof heat insulation board has wide application, can be used for manufacturing fireproof escape equipment such as fireproof doors, fireproof cabinets and the like, and has longer heat insulation effect.
