It relates to a fire protection belt that neutralizes the properties of the soil to obtain the effect of a soil modifier, and a natural mat equipped with a function to secure an access road in case of fire.

Recently, various vehicles for extinguishing forest fires have been developed. In particular, various small fire fighting vehicles with improved mobility are being developed so that they can move quickly to the wildfire area. Such a forest fire extinguishing vehicle is equipped with a fire protection water injection facility, for example, a fire water tank, a fire water pump, and a water spray hose, and enables rapid fire extinguishing by moving quickly on a narrow and sloping road.

However, although such a conventional forest fire extinguishing vehicle has the advantage of excellent mobility, it cannot move on difficult roads and rough terrain, that is, narrow and sloping roads, swamps and mountainous terrain, etc. The disadvantage is pointed out that it is impossible to extinguish a wildfire from a distance.

In order to solve these problems, recently, in consideration of environmental problems, green problems, global warming problems, etc., development of mats using materials with various functionalities, eco-friendliness, green properties, pollution control properties, new materials properties, and waste recyclability, etc. This is a necessary trend.

Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

1 is an exemplary view showing a method of manufacturing a natural mat having a fire protection belt and a function of securing an access road in case of fire according to the present invention. Natural raw materials can be used, and the present invention describes using palm trees, and after collecting the above-mentioned palm trees and splitting the collected palm trees, the insides of the palm trees are removed so that only the skins can be used, and the palm trees are cut using a cutting and crushing device. And when the crushed, cut and crushed material is put into a rotatable foreign material removal container made of a mesh network and the foreign material removal container is rotated, the foreign material is discharged out of the foreign material removal container made of a mesh network and short fibers Only the fibers in the state are left inside the foreign substance removal container.

As described above, after collecting the short fibers made of the fibers of the palm tree, drying and opening the dried short fibers using a carting means so that the short fibers do not become tangled, a natural fiber preparation process (S100) of collecting the short fibers is performed.

After performing the natural fiber preparation process (S100), a short fiber made of natural fiber is impregnated in water mixed with ocher, heated to boil and dyed, followed by a decay prevention process (S200). The reason for performing the anti-corruption process (S200) is to prevent the short fibers made of natural materials from easily decaying and to have the same color as soil, and when the short fibers are impregnated with water mixed with loess, the loess becomes sweet. This is because it is adsorbed into the interior of the fiber, so that the flame retardant effect can also be obtained.

On the other hand, after completion of the anti-corruption process (S200), a surface treatment process (S300) of removing the loess attached to the surface of the fiber while drying the short fibers holding moisture by the anti-corruption process is performed.

The short fibers that have been subjected to the anti-corruption process (S200) and the surface treatment process (S300) have a flame retardant effect and a vivid color. will unfold

The reason for stacking and arranging the mesh net so that it is evenly spread to a certain thickness on a spreading jig made by fixing the mesh network to the support frame using the short fibers that have been subjected to the surface treatment process (S300) as described above, and placing the short fibers on the mesh network for lamination This is because it is easily dried through good wind and also because it is easy to spread the short fibers to form a sheet.

In a state in which the short fibers are neatly stacked on the spreading jig, an adhesive means is sprayed on the short fibers spread on the mesh network, and the operation of stacking the short fibers thereon is repeated several times to make a sheet made of short fibers using a natural material. A sheet forming process (S400) of forming (10) is performed.

The adhesive means used to perform the sheet forming process (S400) may be used by mixing liquid latex or latex and water in a 1:1 ratio. The reason for using the liquid latex for the bonding means is that it is easy to spray and has excellent elasticity because it is a natural material.

In a state in which the short fibers are laminated on the spreading jig as described above, the liquid bonding means is sprayed to adhere the short fibers, and the sprayed bonding means is dried in the sun to dry.

On the other hand, gas emission is produced separately from sheet formation. As for the gas discharge, the gas discharge is used alone or a mixture thereof by adsorbing CO ₂ gas to sheabot, zeolite, and attafolgite.

The sorbot, zeolite, and attapolgite are inorganic substances capable of adsorbing gas. As shown in FIG. 5, carbon dioxide and nitrogen were adsorbed to the zeolite.

As it can be seen that the adsorption rate is different depending on the temperature, in the graph above, a lot of adsorption is performed at 25° C., and as the temperature increases, the adsorbed CO ₂ and nitrogen gas are discharged. At this time, if the starch is coated after adsorbing the gas to the gas discharge, the gas is discharged only when the coating layer 20 made of the starch is destroyed.

Therefore, since the starch is lost when the destructive temperature of the starch is 200° C. or higher, gas is not discharged at a normal temperature, but CO ₂ gas is discharged as the starch is initially extinguished by the fire temperature due to the occurrence of a fire.

Meanwhile, when a fire occurs by further mixing calcium carbonate (CaCo ₃ ) with the gas discharge, CaCO3 → CaO + CO ₂ reacts with high heat to release CO ₂ to extinguish the fire, and then the calcium oxide (CaO) is sprayed water (H ₂ O) reacts to neutralize the acidified soil.

By adsorbing CO ₂ gas to the sorbet, zeolite, and attafolgite, the gas exhaust using either alone or a mixture thereof extinguishes the initial fire, and if the initial fire extinguishing fails, calcium carbonate (CaCo ₃ ) is secondary Extinguish the fire by emitting CO ₂ gas at a temperature of 800℃ or higher.

A coating solution using a gas discharge having the above effects exhibits a non-combustible effect and a fire extinguishing effect, and the coating solution is 20 to 30 parts by weight of kaolinite, 10 to 15 parts by weight of water, 20 to 30 parts by weight of graphite, and 10 ~15 parts by weight and a structure made by mixing 55 to 35 parts by weight of a gas exhaust for discharging CO ₂ gas when the temperature is higher than a certain temperature.

Meanwhile, a coating layer forming process (S500) of forming the coating layer 20 by spraying or applying a coating solution on both sides of the sheet 10 made by performing the sheet forming process is performed.

The present invention having the above structure can extinguish a fire by blocking oxygen by covering the ignited place in case of a fire or forest fire while installing it on a walking path or a hiking path to prevent slipping, etc. If the building is covered in case of an occurrence, it is possible to prevent the fire from moving to the building and the building from being destroyed. In addition, when heated above a certain temperature, CO ₂ gas is emitted to prevent the spread of fire and extinguish the fire _. After discharge, it reacts with water to neutralize the properties of the acidified soil so that the effect of the soil modifier can be obtained.

The natural mat of the present invention as described above is installed with a certain width to prevent the spread of a forest fire to form a fire belt or is used as a fire belt and has a function to secure an access road when a forest fire occurs, and also when a fire occurs in a thick forest. If the building is covered to protect the building from fire, the fire can be transferred to the building and the building can be prevented from being destroyed. In addition, when heated above a certain temperature, CO ₂ gas is emitted to prevent the spread of fire and extinguish the fire. It is a very useful invention, such as neutralizing the properties of the acidified soil by reacting with water after discharging CO ₂ gas, thereby obtaining the effect of a soil modifier.
