Description

Technical Field

[0001] This utility model relates to the technical field of polyurethane hoses, and in particular to a novel corrosion-resistant and oxidation-resistant polyurethane hose. Background Technology

[0002] In existing technologies, polyurethane hoses are widely used in liquid and gas transmission systems due to their excellent flexibility and chemical resistance. However, with the increasing complexity and harshness of industrial environments, traditional polyurethane hoses are gradually revealing their limitations in certain specific applications. For example, in industries such as chemical, petroleum, and food processing, hoses not only need to withstand high-temperature and high-pressure working environments, but also need to cope with the erosion of various corrosive media and oxidizing substances, which places higher demands on the material properties and structural design of the hoses.

[0003] While traditional polyurethane hoses offer some resistance to chemical corrosion, their inner layer material is prone to degradation when exposed to highly corrosive media or high-temperature environments for extended periods. This degradation leads to decreased hose performance and even leaks. Furthermore, traditional hoses suffer from insufficient mechanical strength, particularly in applications involving frequent bending and stretching. These hoses are susceptible to fatigue-induced breakage or deformation, compromising system stability and safety. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a novel corrosion-resistant and oxidation-resistant polyurethane hose with good stability and high safety.

[0005] This utility model discloses a novel corrosion-resistant and oxidation-resistant polyurethane flexible hose, comprising:

[0006] The inner layer is made of polymer material and has chemical stability and temperature resistance.

[0007] The intermediate layer, which wraps around the inner layer, contains a reinforcing fiber web structure to provide mechanical strength and flexibility;

[0008] The outer layer, which wraps around the middle layer, is a corrosion-resistant and oxidation-resistant coating, giving the entire hose excellent corrosion and oxidation resistance.

[0009] A protective coating is applied to the outer wall, and the protective coating is made of highly weather-resistant materials.

[0010] Furthermore, the inner, middle, and outer layers are tightly bonded together through chemical bonding or thermal fusion.

[0011] Preferably, the inner layer polymer material is selected from a variety of combinations of polyether polyurethane and polyester polyurethane to optimize the flexibility and durability of the hose.

[0012] Furthermore, the reinforcing fiber mesh structure is woven from glass fiber, aramid fiber, and carbon fiber to improve the hose's pressure resistance and abrasion resistance.

[0013] Preferably, the outer anti-corrosion and anti-oxidation coating contains nano-sized metal oxide particles, which are uniformly dispersed in the outer matrix, giving the hose surface excellent protective properties.

[0014] Furthermore, the nanoscale metal oxide particles are preferably selected from a combination of titanium dioxide, zinc oxide, and aluminum oxide.

[0015] Preferably, the protective coating is applied to the outer wall by spraying, and the protective coating material is selected from a variety of combinations of epoxy resin, fluorocarbon polymer, and siloxane resin.

[0016] Furthermore, the outer surface is marked with information including product model, production date, manufacturer information, and safety instructions for use, to facilitate user identification and correct use.

[0017] This design incorporates a novel corrosion- and oxidation-resistant polyurethane hose: The inner layer is made of a high-molecular material, possessing chemical stability and temperature resistance, ensuring excellent performance even when materials flow through it. The middle layer, encasing the inner layer, contains a reinforcing fiber mesh structure, providing not only mechanical strength but also excellent flexibility, making the hose resistant to breakage or deformation during bending and stretching, suitable for various complex applications. The outer layer, encasing the middle layer, is a corrosion- and oxidation-resistant coating, giving the entire hose excellent corrosion and oxidation resistance, effectively extending its service life, reducing maintenance costs, and ensuring long-term reliability. A protective coating applied to the outer wall, made of highly weather-resistant materials, further enhances the hose's resistance to ultraviolet radiation, chemical corrosion, and other environmental factors, ensuring superior performance and durability even outdoors or in harsh environments.

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] This utility model relates to a novel corrosion-resistant and oxidation-resistant polyurethane hose, such as... Figures 1 to 4 As shown, it includes:

[0025] Inner layer 1 is made of polymer material and has chemical stability and temperature resistance.

[0026] Intermediate layer 2, which wraps around the outer layer 1, contains a reinforcing fiber web structure to provide mechanical strength and flexibility;

[0027] The outer layer 3 is wrapped around the middle layer 2. The outer layer 3 is an anti-corrosion and anti-oxidation coating, which gives the entire hose excellent anti-corrosion and anti-oxidation capabilities.

[0028] Protective coating 4 is applied to the outer wall of outer layer 3. Protective coating 4 is made of highly weather-resistant material.

[0029] The inner layer 1 is made of a high-polymer material, possessing chemical stability and temperature resistance, ensuring that the hose maintains excellent working performance when raw materials flow through it. The middle layer 2 wraps around the inner layer 1 and includes a reinforcing fiber mesh structure, which not only provides mechanical strength but also gives the hose good flexibility, making it less prone to breakage or deformation during bending and stretching, suitable for various complex application scenarios. The outer layer 3 wraps around the middle layer 2 and is an anti-corrosion and anti-oxidation coating, giving the entire hose excellent anti-corrosion and anti-oxidation capabilities, effectively extending the service life of the hose, reducing maintenance costs, and ensuring long-term reliability. The protective coating 4 is applied to the outer wall of the outer layer 3 and uses highly weather-resistant materials, further enhancing the hose's ability to resist ultraviolet rays, chemical corrosion, and other environmental factors, ensuring that the hose exhibits excellent performance and durability even outdoors or in harsh environments.

[0030] As a preferred option, such as Figures 1 to 4 As shown, the inner layer 1, the middle layer 2, and the outer layer 3 are tightly bonded together by chemical bonding or thermal fusion.

[0031] This tight bonding method ensures seamless connection between layers, avoiding delamination or peeling, thus greatly enhancing the overall structural stability and durability of the hose. Chemical bonding or thermal fusion not only improves the bonding strength between the layers but also effectively prevents moisture, chemicals, and other harmful substances from penetrating into the interlayer, further enhancing the hose's corrosion and oxidation resistance. In addition, the tight bonding allows the hose to evenly transmit loads when subjected to mechanical stresses such as internal and external pressure, bending, and tension, reducing the risk of breakage due to stress concentration and extending the hose's service life.

[0032] As a preferred option, such as Figures 1 to 4 As shown, the polymer material of the inner layer 1 is selected from a variety of combinations of polyether polyurethane and polyester polyurethane to optimize the flexibility and durability of the hose.

[0033] This material selection optimizes the flexibility and durability of the hose. Polyether polyurethane has excellent hydrolysis resistance and low-temperature flexibility, allowing the hose to maintain good physical properties in humid or cold environments, and is not prone to embrittlement or aging. Polyester polyurethane, on the other hand, provides higher mechanical strength and abrasion resistance, making it particularly suitable for applications subject to high pressure or abrasion. By selecting one of these two materials or using them in combination, the characteristics of the hose can be flexibly adjusted according to specific application requirements, ensuring optimal performance under different working conditions. In addition, both polyether and polyester polyurethane have good chemical stability and temperature resistance, further enhancing the overall performance of the hose, extending its service life, and reducing maintenance costs.

[0034] As a preferred option, such as Figures 1 to 4 As shown, the reinforcing fiber mesh structure is woven from glass fiber, aramid fiber and carbon fiber, and is used to improve the pressure resistance and abrasion resistance of the hose.

[0035] This selection significantly enhances the hose's pressure resistance and abrasion resistance. Glass fiber provides excellent mechanical strength and heat resistance, allowing the hose to maintain stable physical properties even under high pressure and high temperature conditions. Aramid fiber, known for its high strength and lightweight characteristics, not only enhances the hose's tensile strength but also gives it better flexibility and fatigue resistance, making it particularly suitable for applications requiring frequent bending and stretching. Carbon fiber possesses extremely high rigidity and corrosion resistance, further improving the hose's durability and environmental adaptability, especially performing exceptionally well under conditions of severe chemical corrosion and mechanical wear. By selecting one of these three fibers or combining them in weaving, the characteristics of the reinforcing fiber web structure can be flexibly adjusted according to specific application requirements, ensuring that the hose exhibits optimal pressure resistance and abrasion resistance under different working conditions.

[0036] As a preferred option, such as Figures 1 to 4As shown, the anti-corrosion and anti-oxidation coating of the outer layer 3 contains nano-sized metal oxide particles, which are uniformly dispersed in the matrix of the outer layer 3, giving the hose surface excellent protective properties.

[0037] The nanoscale metal oxide particles are preferably selected from a combination of titanium dioxide, zinc oxide, and aluminum oxide;

[0038] These nanoscale metal oxide particles significantly enhance the coating's corrosion and oxidation resistance. By forming a dense protective barrier at the microscopic level, they effectively block the penetration of moisture, oxygen, and other corrosive media, thereby extending the service life of the hose and reducing maintenance requirements. The uniform dispersion of the particles ensures the consistency and stability of the coating performance, avoiding corrosion spots or weakened areas caused by insufficient local protection. In particular, titanium dioxide has highly efficient photocatalytic activity, which can decompose organic pollutants and give the coating a self-cleaning function. Zinc oxide provides good ultraviolet absorption capacity, protecting the hose from ultraviolet damage, while aluminum oxide enhances the coating's hardness and wear resistance, further improving the hose's durability and environmental adaptability.

[0039] As a preferred option, such as Figures 1 to 4 As shown, the protective coating 4 is applied to the outer layer 3 wall by spraying, and the material of the protective coating 4 is selected from a combination of epoxy resin, fluorocarbon polymer, and siloxane resin.

[0040] This design significantly enhances the hose's weather resistance and protective performance. The spraying method ensures that the protective coating 4 can evenly cover the surface of the outer layer 3, forming a continuous and non-porous protective film that effectively prevents external environmental factors from affecting the hose. Epoxy resin provides excellent adhesion and chemical stability, allowing the protective coating to adhere firmly to the outer layer 3 and not easily peel off or be damaged. Fluorocarbon polymers are known for their excellent UV resistance and chemical corrosion resistance, giving the hose a long outdoor service life and stable physical properties. Siloxane resin not only has good flexibility and temperature resistance, but also enhances the coating's waterproof and anti-fouling capabilities, ensuring that the hose remains clean and functional in humid or dusty environments. By selecting a combination of these three materials, the hose is ensured to exhibit excellent weather resistance and durability under various complex working conditions.

[0041] As a preferred option, such as Figures 1 to 4 As shown, the outer layer 3 surface is marked with information including product model, production date, manufacturer information, and safety instructions for use, to facilitate user identification and correct use;

[0042] This design significantly enhances user convenience. Clear product model identification helps users quickly confirm hose specifications, ensuring accurate selection and replacement. The production date marking allows users to understand when the product was manufactured, aiding in assessing hose lifespan and performance status for proper maintenance and replacement. Manufacturer information provides traceability, enhancing user trust in product quality and facilitating after-sales service and support. Safety instructions provide necessary operating guidelines and precautions, preventing safety hazards or performance degradation due to misuse. This labeling information not only simplifies the user identification process and improves efficiency but also enhances product transparency and reliability, playing a crucial role in promoting correct use and extending hose lifespan.

[0043] This utility model discloses a novel corrosion-resistant and oxidation-resistant polyurethane hose. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0044] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
