Description

Technical Field

[0001] The invention relates to the technical field of fire hoses, and in particular to a surface flame-retardant fire hose and a preparation method thereof. Background Art

[0002] Generally speaking, there will be burning materials flying around at the scene of fire rescue. For the fire hoses commonly used at present, burning materials falling on the surface of the fire hoses can easily cause the surface of the fire hoses to burn, thereby causing damage to the fire hoses and water leakage, which will not only cause the loss of the fire hoses, but also be detrimental to fire rescue.

[0003] In view of the problem that such fire hoses are easily burned by the burning materials at the fire scene, the existing technology generally adopts a method of setting a number of corresponding water holes on the surface of the fire hose, so that the fire hose can leak a part of water to its surface during the water supply process, so as to keep the surface of the fire hose moist, thereby preventing the fire hose from being ignited by the burning materials falling on its surface. However, the problem faced by this method is that since a number of water holes are set on the surface of the fire hose, this will cause the water pressure in the fire hose to decrease, thereby causing the water range to be greatly reduced, which will have a greater impact on fire rescue. Summary of the invention

[0004] The purpose of the present invention is to address the problem that traditional fire hoses are easily burned by combustibles dropped from the fire scene during use in fire rescue, resulting in damage and leakage of the fire hose. However, the current method of arranging water holes on the surface of the fire hose to keep the surface of the water hose moist to prevent the water hose from being ignited by combustibles dropped on its surface, but this method may cause the water pressure in the water hose to decrease, resulting in a significant reduction in the range of water used for fire rescue, which is not conducive to fire rescue. The present invention proposes a surface flame-retardant fire hose, which aims to solve the problem that the existing fire hose is easily burned and damaged by combustibles dropped from the surface during fire rescue. At the same time, there is no need to arrange water holes on the surface of the water hose, which will not reduce the water supply pressure of the water hose and will not cause the range of the water to be reduced.

[0005] To achieve the above object, the present invention is implemented by the following technical solutions:

[0006] The present invention provides a surface flame-retardant fire hose, which comprises a fire hose body and a flame-retardant layer arranged on the surface of the fire hose body;

[0007] The flame retardant layer is formed by coating a flame retardant coating material, and the flame retardant coating material includes the following components in parts by weight: 80 to 120 parts of water-based flame retardant PU, 0.5 to 2.0 parts of a curing agent, and 3.0 to 8.0 parts of a plastic pigment.

[0008] Specifically, in the fire rescue front, there are often cases where burning materials fall on the surface of the fire hose. Traditional fire hoses cannot cope with such burning materials falling on the surface. The burning of the burning materials will cause the hose to leak and fail. On the one hand, this will cause the loss of the fire hose. On the other hand, the burning of the hose will also bring great pressure to the fire rescue. The surface flame-retardant fire hose of the present invention is provided with a flame-retardant layer formed by special materials on its surface. Even if the burning materials fall on the surface of the fire hose, the burning materials cannot burn the fire hose in a short time. Therefore, such situations can be avoided, the economic losses caused by the burning of the hose can be avoided, and the normal use of the hose can be guaranteed, which is conducive to fire rescue.

[0009] Furthermore, a surface flame-retardant fire hose: the flame-retardant coating material also includes 3.0 to 10.0 parts of wear-resistant material.

[0010] Furthermore, a surface flame-retardant fire hose: the flame-retardant coating material also includes 5.0 to 8.0 parts of wear-resistant material.

[0011] Furthermore, a surface flame-retardant fire hose: the wear-resistant material is selected from any one or more of polyethylene fiber, steel fiber, nylon plastic, and wear-resistant rubber.

[0012] Furthermore, a surface flame-retardant fire hose: the flame-retardant coating material includes the following components in parts by weight: 90 to 110 parts of water-based flame-retardant PU, 1.0 to 1.5 parts of a curing agent, and 4.0 to 6.0 parts of a plastic pigment.

[0013] Furthermore, a surface flame-retardant fire hose: the flame-retardant coating material includes the following components in parts by weight: 100 parts of water-based flame-retardant PU, 1.0 parts of curing agent and 5.0 parts of plastic pigment.

[0014] Furthermore, a surface flame-retardant fire hose: the water-based flame-retardant PU is PU6288 produced by Taixing Zhongfang Xingtai New Materials Co., Ltd.

[0015] Furthermore, a surface flame-retardant fire hose: the curing agent is selected from MDI monomer.

[0016] Furthermore, a surface flame-retardant fire hose: the plastic pigment is selected from one or more of blue powder, iron red, titanium nickel yellow, titanium chrome brown, titanium dioxide, zinc oxide, and copper chrome black.

[0017] The present invention also provides a method for preparing a surface flame-retardant fire hose, wherein the flame-retardant coating material is uniformly coated on the surface of the fire hose body, and then dried at 70 to 90° C. to form a flame-retardant layer to obtain a flame-retardant fire hose.

[0018] Beneficial effects of the present invention:

[0019] (1) The surface flame-retardant fire hose provided by the present invention forms a special flame-retardant layer on the surface of the fire hose. Even if the burning objects at the fire scene fall on the surface of the fire hose, the burning objects cannot burn the fire hose in a short time due to the setting of the specially formulated flame-retardant coating material, thereby meeting the use requirements at the fire rescue scene.

[0020] (2) The surface flame-retardant fire hose provided by the present invention, through the optimized design of the flame-retardant coating material, on the one hand, enables the fire hose to have a good flame-retardant effect, and can easily cope with the short-term burning of the burning materials dropped on the surface of the hose at the fire rescue site; on the other hand, the fire hose of the present invention does not need to be provided with water holes on its surface, and the fire hose is prevented from being ignited by the burning materials dropped on its surface by maintaining the surface of the hose moist. Since the fire hose of the present invention does not need to be provided with water holes, it will not cause the water pressure to drop during the water supply process, thereby shortening the range of the rescue water, which is beneficial to the fire rescue work. At the same time, since the fire hose of the present invention does not need to be provided with water holes on the surface of the hose, it can also avoid the loss of water used to maintain the wet part of the surface of the hose and avoid the waste of water resources. This is particularly important in areas where it is difficult to obtain water sources. More water can be reserved for fire rescue, which can directly improve the efficiency of fire rescue, reduce the time of fire extinguishing, and reduce the losses caused by fire.

[0021] (3) The surface flame-retardant fire hose provided by the present invention introduces special wear-resistant materials into the flame-retardant coating material and optimizes the ratio thereof, so that the formed flame-retardant layer has both flame-retardant effect and excellent wear-resistant effect. That is, the surface flame-retardant fire hose of the present invention has a flame-retardant layer that can withstand being dragged on the ground 500 to 900 times without showing obvious wear during the water supply process of the hose.
