Abstract

The invention relates to a fire hose containing a high-binding-force functional coating and the coating spraying equipment. The fire hose comprises a rubber inner pipe, a fiber framework layer, an external protective layer and a functional coating layer which are coaxially sleeved from inside to outside in sequence, wherein the rubber inner pipe is made of a rubber/resin composite material; the fiber framework layer is made of a woven material formed by blending polyamide fibers, polypropylene fibers and brucite fibers; the external protective layer adopts composite silica micropowder/magnesium hydroxide/desulfurized rubber powder modified and doped ethylene propylene diene monomer rubber; and the functional coating layer adopts conventional functional coating or functional paint sold in the market. The fire hose containing a high-binding-force functional coating and the coating spraying equipment carry out targeted reasonable design on the multilayer structure material of the rubber inner pipe, greatly improve the physical and chemical properties of the fire hose, and obviously improve the bonding force of the coating on the outer layer by matching with corresponding coating spraying equipment, so that the comprehensive performance is more excellent.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting hose containing high-binding functional paint and paint spraying equipment. Background technique [0002] Fire-fighting equipment refers to equipment used for fire extinguishing, fire prevention and fire accidents, and equipment for professional fire extinguishing. A fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. A traditional fire hose is lined with rubber and wrapped with a linen braid on the outside. Advanced fire hoses are made of polymeric materials such as polyurethane. There are metal joints at both ends of the fire hose, which can be connected to another rubber hose, polyurethane hose, PVC fire hose, etc. to extend the distance or connect to a nozzle to increase the liquid injection pressure. [0003] In the prior art, the outer layer of the fire hose used for fire protection is current...
