Description

Technical Field

[0001] The utility model relates to a steel-plastic composite belt, in particular to a flame-retardant steel-plastic composite belt, belonging to the technical field of steel-plastic composite belts. Background Art

[0002] Steel-plastic composite tape is a high-performance composite material consisting of steel tape and plastic. It fully combines the high strength and durability of steel with the excellent corrosion resistance and insulation of plastic. This material is usually used in cable protection, pipeline maintenance, construction engineering and various packaging fields. Steel-plastic composite tape not only has good mechanical properties and anti-aging properties, but also can adapt to various harsh environments, providing long-term and reliable protection solutions for projects.

[0003] However, the flame retardant properties of existing steel-plastic composite tapes may be insufficient, and they may quickly promote combustion in high-temperature environments such as fires, causing the fire to spread faster, increasing the severity and losses of disasters. When used in cable protection and building internal structures, the insufficient flame retardancy of this material may significantly increase the risk of fire safety, threatening not only the lives of personnel, but also the paralysis of the power system, thereby affecting the response time and efficiency of emergency services, causing greater economic losses and social impacts;

[0004] Therefore, a flame retardant steel-plastic composite belt is proposed. Utility Model Content

[0005] In view of this, the utility model provides a flame retardant steel-plastic composite belt to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0006] The technical solution of the utility model is implemented as follows: it includes a steel-plastic composite belt body, the steel-plastic composite belt body includes a base layer, a first functional layer and a second functional layer, the first functional layer includes an aluminum hydroxide coating and a phosphorus coating, and the second functional layer includes an intumescent flame retardant coating and a nanotechnology coating.

[0007] Further preferably, the first functional layer is arranged on the outside of the base layer, and the second functional layer is arranged on the outside of the first functional layer.

[0008] Further preferably, the aluminum hydroxide coating is disposed on the outside of the base layer, and the phosphorus-based coating is disposed on the outside of the aluminum hydroxide coating.

[0009] Further preferably, the intumescent flame retardant coating is disposed on the outside of the phosphorus-based coating, and the nanotechnology coating is disposed on the outside of the intumescent flame retardant coating.

[0010] Further preferably, the thickness of the aluminum hydroxide coating and the phosphorus-based coating are consistent, and are both 1 cm-2 cm.

[0011] Further preferably, the thickness of the intumescent flame retardant coating and the nanotechnology coating are consistent, and are both 1 cm-2 cm.

[0012] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0013] The utility model provides a first functional layer including an aluminum hydroxide coating and a phosphorus coating, wherein the aluminum hydroxide coating generates water by decomposing at high temperature, thereby reducing the temperature of the material surface, and the released water vapor helps to dilute the oxygen in the flame and slow down the combustion rate. In addition, its decomposition product can also form a protective film to improve the heat resistance and flame retardancy of the material, and is suitable for steel-plastic composite belt applications that require a higher flame retardant grade and thermal stability. The phosphorus coating will prompt the material surface to form a dense carbon layer when heated or burned. This carbon layer can effectively isolate the transfer of oxygen and heat and prevent the spread of flames. Since it can form a protective layer on the surface, this coating not only improves the flame retardancy, but also enhances the oxidation resistance of the material itself. In order to improve the performance and stability of the coating, a second functional layer including an intumescent flame retardant coating and a nanotechnology coating is provided. The intumescent flame retardant coating will rapidly expand to form a foamy carbon layer when encountering a fire source. This lightweight protective layer can effectively isolate the contact between heat and oxygen, slow down or even prevent the spread of fire. The formation of the intumescent layer also helps to reduce the smoke and toxic gases produced by combustion, which is crucial to improving the escape and rescue time of personnel. The nanotechnology coating can significantly improve the uniformity of the coating and its adhesion to the substrate. At the same time, nanomaterials can also introduce new flame retardant mechanisms (such as catalytic carbonization, changing the pathway of chemical reactions during combustion, etc.), thereby greatly improving the comprehensive flame retardant properties of the material without increasing the volume and weight.
