Abstract

The present application belongs to the technical field of protective clothing, and provides a risk-avoiding clothing with nickel-plated magnetized hollow glass microsphere armor pieces. The core of the risk-avoiding clothing is an armor piece covered by an outer layer, which is composed of upper and lower interlayers, a core layer and a bonding agent. The interlayers are made of aluminum foil composite glass steel material, the core layer is made of nickel-plated magnetized hollow glass microsphere composite foam material, and the bonding agent is made of high-strength epoxy resin. The armor piece is formed by VARI (vacuum assisted resin infusion molding technology) process, and is used after being processed into a specific specification. The fully-covered armor piece can provide comprehensive protection for the wearer and reduce the impact on the flexibility of the wearer. The use of the nickel-plated magnetized hollow glass microsphere technology in the composite foam material improves the strength of the single microsphere. The surface of the microsphere has the same magnetism after being magnetized, which can reduce the aggregation or close distance of the microspheres during stirring with the resin, thereby further improving the strength of the composite foam material.

Description

Technical Field

[0001] This invention belongs to the technical field of protective clothing, and relates to a protective suit with nickel-plated magnetized hollow glass microsphere armor plates. Background Technology

[0002] The ocean contains abundant and diverse resources and covers 71% of the Earth's surface. Against the backdrop of rapid technological development, increasing demand for resources, and more frequent global trade, the concept of marine platforms is evolving rapidly, and activities at sea are increasing. However, this also brings more safety hazards.

[0003] Generally, offshore platforms carry large quantities of fossil fuels and complex electrical equipment. Due to the harsh marine environment, they are prone to accidents such as short circuits and equipment malfunctions, which can lead to various uncontrollable fires. Typical examples include fossil fuel and natural gas extraction platforms and ships transporting flammable and explosive materials, which are highly susceptible to explosions and large-scale fires when exposed to a source of ignition. Furthermore, offshore platforms are typically far from land, making rescue difficult. Personnel falling into the water may face various unforeseen circumstances such as unconsciousness and exhaustion, all posing a significant threat to the lives of those working at sea. Therefore, at present, there is an urgent need for a safety suit that can simultaneously provide buoyancy, fire protection, and a certain degree of impact resistance to protect people's lives in the face of dangers such as drowning, fire, and explosions.

[0004] Patent CN202110270316.2 by Ma Zhe et al. of Dalian University of Technology describes a fire-resistant and buoyant marine work suit based on HGM / ER, which utilizes epoxy resin and hollow glass microspheres to create a foam material that simultaneously provides buoyancy and fire resistance. The higher the filling rate of the hollow glass microspheres, the lighter the overall composite material. However, currently, the strength of hollow glass microspheres is relatively lower than that of epoxy resin. Increasing the filling rate of hollow glass microspheres leads to a decrease in the overall strength of the composite material. Furthermore, in the process of mixing epoxy resin and hollow glass microspheres, it is difficult to fully stir the hollow glass microspheres to ensure their uniform distribution within the resin. The aggregation and adhesion of the hollow glass microspheres further reduces the strength of the composite foam material.

[0005] Secondly, the composite foam material is a rigid material and lacks flexibility. It cannot be bent like common fabrics and rubber products. Therefore, its application in emergency suits requires a modular approach. Regarding the division and design of modules, traditional ordinary life jackets are only vest-style, used for emergency purposes, and have no special requirements. They abandon the flexibility required for human movement and are simply divided into several large modules. In the paper "Protective Performance and Research Progress of Explosion-Proof Clothing" by Wang Huiling et al. of Nantong University [J]. Textile Report, 2016, (05): 33-37, the protective performance of explosion-proof clothing and special clothing such as police and military uniforms are divided into modules for the protection of key parts such as chest, elbow, shoulder, and groin. The protection effect of other parts is relatively poor. The joints are relatively stiff, the weight is large, and the flexibility is not enough. Wearing and moving are inconvenient, which may delay the escape process and self-rescue after falling into the water, thus threatening the safety of personnel. Summary of the Invention

[0006] To overcome the shortcomings of the aforementioned technologies, this invention proposes a protective suit using nickel-plated magnetized hollow glass microsphere armor plates. Hollow glass microspheres are relatively weaker than resin materials. By plating a layer of metallic nickel onto the outer surface of the hollow glass microspheres, their compressive strength can be improved, thereby enhancing the overall strength of the composite foam material. Therefore, the filling rate of the hollow glass microspheres can be further increased in the design, reducing the density of the composite foam material. Secondly, the nickel-plated hollow glass microspheres are magnetized, creating a certain repulsive force between different nickel-plated magnetized hollow glass microspheres. This reduces the aggregation and close adhesion of the hollow glass microspheres during mixing with the epoxy resin material, resulting in a more uniform overall distribution and improved strength of the composite foam material. Finally, the composite foam material module is designed as a fish-scale biomimetic armor plate with a sandwich structure. The armor plates are designed to be of appropriate size and uniform specifications, and their structure is designed to be stacked and arranged according to biomimetic principles. They are fixed to the outer surface of the protective suit using metal chains and aramid threads, ensuring that the overall protective suit does not hinder normal movement of the wearer.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A protective suit featuring nickel-plated magnetized hollow glass microsphere armor plates is disclosed. The suit comprises an outer armor plate layer 1 (composed of multiple stacked armor plates with identical structures), an aerogel cotton middle layer 2, and a sandwich mesh nylon inner layer 3. The aerogel cotton middle layer possesses certain heat insulation, flame retardant, and impact resistance properties, while the sandwich mesh nylon inner layer is soft and comfortable, improving the feel of the suit against the body and cushioning impact forces through its elastic deformation.

[0009] Each armor plate is a circular structure (a thin circular sheet protruding from the center of the upper and lower surfaces, with the upper and lower surfaces cut at a certain angle), including an upper layer 4, a middle core layer 5, a lower layer 6, and an adhesive 7. The upper and lower layers and the middle core layer 5 are fixed together by the adhesive 7. The edges of the upper layer 4 and the lower layer 6 are beveled at an angle of α. All armor plates are fixed to the aerogel cotton middle layer 2 by the beveled edges of the lower layer 6. Adjacent armor plates are stacked by the beveled edges, and finally, the armor plates are stacked on the surface of the aerogel cotton middle layer 2 in a scale-like manner. Details are as follows:

[0010] The upper layer 4 of each single armor plate has a through-hole 8 on its right side, a through-hole 9 on its left side, and a through-hole 10 on its right side. Adjacent overlapping armor plates are connected by a ring-shaped thin metal chain 11, allowing them to stack according to biomimetic principles. Each armor plate is secured to the aerogel cotton middle layer 2 with a high-strength aramid thread 12. Specifically, the upper layer 4 of each single armor plate has a through-hole 8 on its right side, the lower layer 6 has a through-hole 9 on its left side, and a through-hole 10 on its right side. The inclined surface of the lower layer 6 of the armor plate, where it contacts the aerogel cotton middle layer 2, is sewn onto the aerogel cotton middle layer 2 through the through-hole 10 via a high-strength aramid thread 12, similar to a button. Adjacent overlapping armor plates are connected by a ring-shaped thin metal chain 11 passing through the first hole 8 on the right side of one armor plate and the second hole 9 on the left side of another armor plate to form a ring, so that there is a certain relative space for movement between adjacent armor plates to meet the normal activity needs of the wearer.

[0011] The core of the armor plate's surface layer 1 is a nickel-plated magnetized hollow glass microsphere composite material. The upper sandwich layer 4 and lower sandwich layer 6 are made of aluminum foil composite fiberglass, and the middle core layer 5 is also made of nickel-plated magnetized hollow glass microsphere composite material. A high-strength adhesive matrix is ​​filled into the upper and lower sandwich layers and the core layer using a VARI (vacuum-assisted resin infusion molding) process to obtain a high-strength composite armor plate.

[0012] Furthermore, the high-strength adhesive is an epoxy resin with an added curing agent.

[0013] Furthermore, the thickness of the aerogel cotton middle layer 2 is 6mm, the thickness of the sandwich mesh nylon inner layer 3 is 4mm, the arc diameter of the armor plate is 6cm, the equivalent thickness is 2cm, the equivalent thickness ratio of the upper and lower interlayers to the middle core layer 5 is 1:3, the diameter to thickness ratio of the armor plate is 1:3, the inclined angle of the upper interlayer 4 and lower interlayer 6 of the armor plate is 20°, that is, the inclined angle of the armor plate during installation is 20°, and the coverage angle (the coverage angle refers to the central angle formed by the intersection of the two circular planes of the armor plate and the center of the armor plate) is 56° for laying.

[0014] Furthermore, the specific preparation method of the nickel-plated magnetized hollow glass microsphere composite material is as follows: after surface pretreatment and activation treatment of the hollow glass microspheres, they are immersed in nickel ion electrolyte to form a nickel film. Then, they are cleaned to remove residual activator and electrolyte on the surface. Finally, the nickel-plated hollow glass microspheres are placed in a stable strong magnetic field for magnetization. After the preparation is completed, they are thoroughly stirred with resin, a curing agent is added, and the composite foam material is cured to form a composite foam material, which is then cut into the shape of the middle core layer 5 of the armor plate.

[0015] The beneficial effects of this invention are:

[0016] 1) Using nickel-plated magnetic hollow glass microspheres can improve the compressive strength of individual hollow glass microspheres, make their distribution in the resin more uniform, reduce aggregation and adhesion, and improve the overall strength of the composite material. It is preliminarily estimated that a 2cm thick composite foam material can withstand a high-speed fragment of 1.1g at 1600m / s generated by an explosion.

[0017] 2) While meeting the strength requirements, the filling rate of nickel-plated magnetic hollow glass microspheres can be further increased to 40-60%, reducing the overall density of the composite foam material to 0.3-0.5 g / cm³. 3 Composite foam materials of the same volume are lighter and can provide greater buoyancy.

[0018] 3) The protective armor made of composite foam material has excellent impact resistance and buoyancy performance, as well as low thermal inertia. Combined with the upper and lower composite aluminum foil interlayer and the aerogel cotton middle layer, it can effectively resist the transfer of heat to the human body in a fire or explosion.

[0019] 4) The armor plates are designed in the shape of small bionic fish scales and are stacked in a special way to provide comprehensive protection. At the same time, the adjacent armor plates are connected by rings, and the armor plates and aerogel cotton are constrained and fixed with high-strength aramid fibers, which can ensure that the armor plates have a certain degree of mobility to meet the rotation needs of normal human activities.

[0027] The specific embodiments of the present invention will be described in detail below with reference to the technical solutions and accompanying drawings.

[0028] A type of protective suit featuring nickel-plated magnetized hollow glass microsphere armor plates, the specific design of which is as follows: Figure 1 As shown, the garment's fabric layers consist of an outer layer of armor plates (1), a 6mm aerogel cotton middle layer (2), and a 4mm thick sandwich mesh nylon inner layer (3).

[0029] The surface armor plate is mainly composed of upper and lower layers and a core. The core is a middle core 5 of a nickel-plated magnetized hollow glass microsphere composite material. The upper layer 4 and the lower layer 6 are made of aluminum foil composite fiberglass material. The VARI (vacuum-assisted resin injection molding technology) process is used to fill the upper and lower layers and the core layer with a high-strength adhesive matrix to obtain a high-strength composite material armor plate.

[0030] The manufacturing process of nickel-plated magnetized hollow glass microspheres is as follows: First, the hollow glass microspheres undergo simple pretreatment. Due to their extremely small size, only a simple cleaning is required to remove dirt. Then, after the microspheres are dried, an activator is sprayed evenly while turning them over to improve the adhesion between the nickel layer and the surface of the glass microspheres. Next, the hollow glass microspheres are immersed in an electrolyte of nickel sulfate or nickel-plating sulfate for electrodeposition, forming a nickel film on their surface. The nickel-plated hollow glass microspheres are then cleaned to remove any residual activator and electrolyte. Subsequently, the dried nickel-plated hollow glass microspheres are placed in a stable, strong magnetic field for magnetization, ensuring that the magnetic poles on the surface of the microspheres are identical and have a certain repulsive force. Finally, the nickel-plated magnetic hollow glass microspheres and epoxy resin are stirred evenly at a filling rate of 40-60% to produce a product with a density of 0.3-0.5 g / cm³. 3 The composite foam material was cut into the shape of the armor plate sandwich layer 5.

[0031] The armor plates are stacked in the following manner, drawing inspiration from biomimicry and referencing a scale-like stacking pattern. Parameters such as the central angle, arc, central protrusion, and edge thickness of the armor plates are determined through mathematical derivation. This yields the planar and elevational positional relationships between adjacent scales, thus establishing the three-dimensional positional coordinate expression for the entire protective gear. The positional coordinates of other armor plates in the armor system are recursively derived from the coordinates of individual armor plates. In this example, each armor plate is a circular structure (a thin circular sheet with a central protrusion on both the upper and lower surfaces, cut at a certain angle), comprising an upper layer 4, a middle core layer 5, a lower layer 6, and an adhesive 7. The upper and lower layers are fixed to the middle core layer 5 via the adhesive 7. The edges of the upper layer 4 and lower layer 6 are inclined surfaces with an angle of α. All armor plates are fixed to the aerogel cotton middle layer 2 via the inclined surfaces of the lower layer 6. Adjacent armor plates are stacked using these inclined surfaces, ultimately forming a scale-like stack on the surface of the aerogel cotton middle layer 2. The specific structural parameters are as follows: the diameter of the armor plate arc is 6cm, the horizontal projection length of the upper and lower sandwich edges is a = 10mm, the upper surface width is b = 40mm, the thickness is d = 3.6mm, the inclination angle of the edge slope is α = 20°, and the thickness of the composite material sandwich core is c = 15mm.

[0032] The aerogel cotton middle layer 2 has a thickness of 6mm, the sandwich mesh nylon inner layer 3 has a thickness of 4mm, the arc diameter of the armor plate is 6cm, the equivalent thickness is 2cm, the equivalent thickness ratio of the upper and lower interlayers to the middle core layer 5 is 1:3, the diameter to thickness ratio of the armor plate is 1:3, the inclined angle of the upper interlayer 4 and lower interlayer 6 of the armor plate is 20°, that is, the inclined angle of the armor plate during installation is 20°, and the coverage angle (the coverage angle refers to the central angle formed by the intersection of the two circular planes of the armor plate and the center of the armor plate) is 56° for laying.

[0033] The upper layer 4 of the single armor plate has a through hole 8 on its right side, and the lower layer 6 has a through hole 9 on its left side and a through hole 10 on its right side. The inclined surface of the lower layer 6 on the right side, which contacts the aerogel cotton middle layer 2, is sewn onto the aerogel cotton middle layer 2 through the through hole 10 via a high-strength aramid thread 12, similar to a button. Adjacent overlapping armor plates are connected by a ring-shaped thin metal chain 11 passing through the first hole 8 on the right side of one armor plate and the second hole 9 on the left side of another armor plate, forming a ring. This provides a certain amount of relative movement space between adjacent armor plates, meeting the normal activity needs of the wearer.

[0034] The above-described embodiments are merely illustrative of the implementation methods of the present invention, but should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
