Flame-retardance-type fire hose

Abstract

The invention discloses a flame-retardance-type fire hose, and belongs to the technical field of fire fighting equipment. The outer wall of a rubber inner pipe is covered with a nonwoven fabric layer,the outer wall of the nonwoven fabric layer is covered with a soft steel wire layer, and the outer wall of a fireproof paper layer is covered with a high-elasticity waterproof coating layer. The outer wall of the rubber inner pipe is covered with the nonwoven fabric layer, and the outer wall of the nonwoven fabric layer is covered with the soft steel wire layer, wherein soft steel wires have thefunctions of achieving setting protection, and preventing deformation of the fire hose, and besides, the soft steel wires are unlikely to burn, and have a certain flame-retardance effect. A polyesternetwork filament layer is arranged, wherein polyester network filament has excellent elasticity, is not liable to deform, and has an extraordinary flame retardance effect. The fireproof paper layer isarranged, wherein fireproof paper is made of a fire-resistance material or a fireproof material, and the paper which is made of a special material and is not liable to burn has flame-retardance performance, gets carbonized in case of a fire and is incombustible. In the meanwhile, the high-elasticity waterproof coating layer is arranged, and the fireproof paper layer can be protected against erosion of water.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a flame-retardant fire hose. Background technique [0002] The fire hose is a hose used in the fire industry to transport high-pressure water or foam and other flame-retardant liquids. There are metal joints at both ends of the fire hose, which can be connected to another hose to extend the distance or connect to the nozzle. In order to increase the liquid injection pressure, although the traditional fire hose is light in weight and easy to use, it has poor flame retardant effect. When fighting a fire, the outer layer of the fire hose is easy to catch fire; [0003] For this reason, we propose a flame-retardant fire hose. Contents of the invention [0004] The object of the present invention is to provide a flame-retardant fire hose to solve the problems raised in the above-mentioned background technology. [0005] In order to achieve the above object, the pre...
