2. Description of the Related Art Conventionally, as a flameproof sheet for preventing such spread of fire, a sheet using a glass cloth has been used. However, for example, when a gaseous substance is burning, there is a disadvantage that the gaseous substance permeates through the weave of the glass cloth and reignites on the sheet surface. Further, since the glass cloth has a melting temperature of about 850 ° C., there is a possibility that a hole or the like may be opened in an application exposed to a high temperature such as a welding spark.

DETAILED DESCRIPTION OF THE INVENTION FIG. 1 is a sectional view of the present invention.
As is apparent from this figure, the flameproof sheet according to the present invention has a structure in which a halogen-free flame-retardant rubber layer 2 is provided on both surfaces of a cloth body 1 made of halogen-free flame-retardant fibers. In this embodiment, the flame-retardant rubber layer 2 is provided on the surface. However, in the present invention, it is sufficient that at least one side is provided, and a plurality of these layers may be laminated.

As the flame retardant added to make the elastomer flame-retardant, for example, a metal hydrate that releases water of crystallization and lowers the combustion temperature to make it flame-retardant is used . As such a metal hydrate, for example, one or more of magnesium hydroxide, aluminum hydroxide and the like can be used. 100 to 500 parts by weight of such a metal hydrate is added to 100 parts by weight of the rubber component . If the amount is less than 100 parts by weight, the flame retardant effect is small, while if it exceeds 500 parts by weight, the processability is reduced.

In addition to the above-mentioned flame retardants, one or more kinds of phosphorus, for example, red phosphorus, yellow phosphorus and the like are added in order to further improve the flame retardancy . Phosphorus is preferably added in a solid phase or a liquid phase, and particularly has a good function in the solid phase. Since the chemical reaction in the decomposition stage is directed to the direction in which carbon is easily formed, carbon monoxide, carbon dioxide, etc. are hardly formed, so this carbon forms a surface film, physically shields oxygen, and prevents the diffusion of combustible gas And prevent carbon vaporization. The above-mentioned phosphorus is added in an amount of 10 to 50 parts by weight. If the amount is less than 10 parts by weight, there is a possibility that it hardly contributes to flame retardancy.
Exceeding the weight parts may cause the physical properties of the rubber to be impaired.

In addition to the metal hydrate or the metal hydrate and phosphorus, one or more of a phosphate compound and a salt thereof are added to further improve the flame retardancy . Examples of the above-mentioned phosphate compound and phosphate include one or more of metaphosphate, polyphosphate, ultraphosphate, hydrogen orthophosphate and the like. Such compounds and salts become glassy and cover the surface,
Physically shut off oxygen. A phosphate compound as described above,
One or more phosphates are added in an amount of 10 to 100 parts by weight.
If the amount is less than 10 parts by weight, the effect of improving the flame retardancy is small, while if it exceeds 100 parts by weight, the effect is not improved.

If it is less than 1.0 mm, sufficient flame resistance may not be obtained. On the other hand, if it exceeds 1.0 mm, flexibility may be lost, weight may increase, and transportability and workability may be impaired.

EXAMPLE On both sides of a glass cloth, an ethylene propylene (EPDM) rubber layer having a flame retardancy by adding 100 parts by weight of magnesium hydroxide and 50 parts by weight of ammonium phosphate to 100 parts by weight of rubber was used. 3 mm was laminated to produce a flameproof sheet.

For comparison, a flameproof sheet in which three layers of glass cloth were laminated and a glass cloth in which chloroprene rubber flame-retardant compounded rubber was laminated on both sides by 0.3 mm, were covered over the gasoline combustion part.

As a result, the flameproof sheet of the present invention was initially fired from the end, but was easily extinguished by pressing it.
No toxic gas or black smoke was generated. On the other hand, those simply laminated with glass cloth seemed to have disappeared at first, but after a while, fired from the cloth surface. Also,
Since a large number of layers are stacked, the weight is large and handling is inconvenient. Further, the flameproof sheet having the chloroprene rubber layer generated black smoke and cracks on the rubber surface, and the surface was ignited after a further lapse of time.
