Problems solved by technology

[0003] In the prior art, the outer layer of the fire hose used for fire protection is currently commonly used polyester and polyester yarn or polypropylene yarn as the material to form a tubular skeleton. The rubber tube is made of natural rubber and requires a certain thickness and pressure resistance. , wear resistance and other properties, these performance requirements are not only provided by the material itself, most of the existing hoses are coated with corresponding functional coatings on the outer layer, but there is still the problem of poor interface bonding effect, which needs further improvement
In addition, fire hoses are used in special environments, and traditional fire hoses have poor anti-corrosion performance. Due to unstable factors caused by the environment, fire hoses will be corroded to the same degree after long-term use, so , it is very necessary to carry out anti-corrosion processing on the outer layer of the fire hose. At the same time, the fire hose is often used in a high-temperature fire environment, and it also needs to have excellent fire resistance and flame retardancy

Abstract

A paint spraying equipment for a fire hose containing high-binding functional paint, the fire hose includes a rubber inner tube, a fiber skeleton layer, an outer protective layer, and a functional paint layer that are sequentially sleeved on coaxial lines from the inside to the outside , wherein the rubber inner tube is made of rubber / resin composite material; the fiber skeleton layer is made of polyamide fiber / polypropylene fiber / brucite fiber blended braided material; the outer protective layer is made of composite silica powder / magnesium hydroxide / desulfurized rubber Powder-modified and doped EPDM rubber; the functional coating layer adopts commercially available conventional functional coatings or functional paints, and the present invention carries out targeted and rational design of the multi-layer structure material of the rubber inner tube, which greatly improves the safety of the fire hose. Physical and chemical properties, with the corresponding spraying equipment, the binding force of the outer functional coating is significantly improved, and 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 coating spraying equipment for fire-fighting hoses containing high-binding functional coatings. 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 c...
