Abstract

The flame-retardant fireproof paper comprises a fiber layer, an aluminum foil layer and a back glue layer, wherein an adhesive layer which is formed by bonding the fiber layer and the aluminum foil layer to each other is arranged between the fiber layer and the aluminum foil layer. The aluminum foil layer is connected with the back glue layer in a bonding mode through a glue layer arranged in the back glue layer. The back glue layer is a 3M glue layer. The fiber layer is a flexible fiber composite material layer. The flame retardant property can pass 750 ℃ and 850 ℃ tests of a glow wire, and the glow wire extinguishes within 30 seconds after ignition at 850 ℃; and the cost is greatly reduced. The fire-proof paper cost can be reduced while the fire-proof performance of the fire-proof paper is improved.

Description

Flame-retardant fireproof paper

Technical Field

The utility model relates to a heat preservation shock attenuation, fire prevention fire-retardant field.

Background

At present, the fireproof paper on the market is mainly ceramic fiber paper, but the ceramic fiber paper is not uniform, some fireproof paper can pass 750 ℃ glowing filament test, but some fireproof paper can not pass 750 ℃ glowing filament test, and hardly passes 850 ℃ glowing filament test. In addition, the existing ceramic fiber paper is expensive and has high use cost.

SUMMERY OF THE UTILITY MODEL

In view of above situation, in order to solve the problem that above-mentioned technique exists, the utility model provides a fire-retardant fireproof paper, including fibrous layer, aluminium foil layer and gum layer, be equipped with between fibrous layer and the aluminium foil layer with fibrous layer and the mutual complex viscose layer that bonds of aluminium foil layer.

The aluminum foil layer is connected with the back glue layer in a bonding mode through a glue layer arranged in the back glue layer.

The back glue layer is a 3M glue layer.

The fiber layer is a flexible fiber composite material layer.

After the technology provided by the utility model, according to the utility model discloses fire-retardant fireproof paper has following beneficial effect.

1) Tests show that the flame retardant property of the flame-retardant alloy can pass tests of 750 ℃ and 850 ℃ of a glow wire, and the glow wire extinguishes within 30 seconds after ignition at 850 ℃; and the cost is greatly reduced. The fire-proof paper cost can be reduced while the fire-proof performance of the fire-proof paper is improved.

Fig. 1 shows a schematic structural view of a cross section of the flame-retardant fireproof paper according to the present invention.

Detailed Description

Various preferred embodiments of the present invention will be described below with reference to the accompanying drawings. The following description with reference to the accompanying drawings is provided to assist in understanding the exemplary embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to assist understanding, but they are to be construed as merely illustrative. Accordingly, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Also, in order to make the description clearer and simpler, a detailed description of functions and configurations well known in the art will be omitted.

As shown in fig. 1, the flame-retardant fireproof paper comprises a fiber layer 1, an aluminum foil layer 2 and a back glue layer 3, wherein an adhesive layer is arranged between the fiber layer 1 and the aluminum foil layer 2, and the fiber layer 1 and the aluminum foil layer 2 are bonded and compounded with each other.

And the aluminum foil layer 2 and the back glue layer 3 are connected in a bonding manner through a glue layer arranged in the back glue layer 3.

The back glue layer 3 is a 3M glue layer.

The fiber layer 1 is a flexible fiber composite material layer.

According to the application, the flame-retardant fireproof paper is mainly composed of 3 materials, wherein the first layer (the outermost layer) is as follows: special fibers; second layer (intermediate layer): aluminum foil; third layer (innermost layer): 3M glue; the first layer and the second layer are compounded through a gluing process, the third layer and the second layer are adhered to the back of the aluminum foil through the 3M glue, and the novel fireproof paper is formed by the three materials. The flame retardant effect is achieved mainly by the material synthesized by compounding special fibers and aluminum foil, and other materials cannot be synthesized. The special fiber is a flexible fiber composite material.

According to the flame-retardant fireproof paper, through tests, the flame-retardant performance can pass 750 ℃ and 850 ℃ tests of a glow wire, and the glow wire extinguishes within 30 seconds after ignition at 850 ℃; and the cost is greatly reduced. The fire-proof paper cost can be reduced while the fire-proof performance of the fire-proof paper is improved.
