Abstract
Description
Technical Field
[0001] This invention belongs to the field of thin film technology, and in particular relates to a self-healing composite microcapsule film. Background Technology
[0002] A thin film is a layer of material with a relatively small thickness, typically ranging from a few nanometers to a few micrometers. Thin film technology has wide applications in modern science and industry, involving multiple fields, including physics, chemistry, materials science, and engineering.
[0003] Self-healing microcapsule films are innovative materials that combine self-healing capabilities with microcapsule technology. By embedding microcapsules within a matrix material, these films can automatically repair damaged areas when subjected to mechanical damage, external environmental stimuli, or wear, thereby extending the film's lifespan and maintaining its original performance.
[0004] The repair effect of self-healing microcapsule films is usually effective for certain types of damage, such as small cracks or scratches; for larger-scale damage or under high stress conditions, the repair effect of microcapsules may not be sufficient; since self-healing microcapsule films need to maintain toughness, the overall strength of the film is affected.
[0005] To address the aforementioned issues, this application proposes a self-healing composite microcapsule film. Utility Model Content
[0006] The purpose of this invention is to provide a self-healing composite microcapsule film that solves the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This invention relates to a self-healing composite microcapsule film, comprising a base membrane located at the bottom of the body, and further comprising: a composite frame formed at the upper end of the base membrane and along its periphery, the composite frame being a glass fiber and polyethylene molded component; pressure-resistant particles located inside the composite frame and formed on the base membrane, the pressure-resistant particles being evenly staggered in a semi-circular shape; and a microcapsule layer composed of multiple layers located inside and above the composite frame, which, through the outer composite frame and the inner pressure-resistant particles, serves to block large-area pressure and simultaneously form support within the microcapsule layer.
[0009] Furthermore, the microcapsule layers are, from bottom to top, a bottom layer, a middle layer, and a top layer, and the particle size of the self-healing composite microcapsules in the middle layer is larger than that of the microcapsules in the bottom and middle layers.
[0010] Furthermore, the bottom layer is formed on the upper end of the base film and located inside the composite frame, and the thickness of the bottom layer is less than the height of the pressure-resistant particles.
[0011] Furthermore, the middle layer is formed on top of the bottom layer and inside the composite frame, and the bottom at least partially covers the pressure-resistant particles.
[0012] Furthermore, the top layer is formed on the upper surface of the middle layer and the composite frame, and the length and width of the top layer are greater than those of the bottom layer and the middle layer.
[0013] Furthermore, a protective layer located on top of the main body is attached to the top layer.
[0014] Furthermore, the pressure-resistant granules are polypropylene molded components.
[0015] This utility model has the following beneficial effects:
[0016] The bottom and top layers of this invention are composed of small-diameter self-healing microcapsules, while the middle layer is composed of large-diameter self-healing microcapsules. The bottom and top layers encapsulate the top layer while ensuring the flatness of the microcapsule layer. The top layer can withstand damage from smaller pressures. When the pressure increases, the indentation will be deeper, at which point the middle layer will break, achieving a more complete repair effect.
[0017] This invention provides structural reinforcement to the film by setting a composite frame around the film and placing the bottom and middle layers inside. At the same time, pressure-resistant particles located on the base film are set inside the composite frame. Both the composite frame and the pressure-resistant particles provide protection to the microcapsule layer, preventing large-area pressure from causing the entire microcapsule layer to fail.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0031] Please see Figure 1-7 As shown, this utility model is a self-healing composite microcapsule film, including a base membrane 1 located at the bottom of the body, and further including: a composite frame 2 formed at the upper end of the base membrane 1 and along its periphery, the composite frame 2 being a glass fiber and polyethylene molded component; pressure-resistant particles 3 located inside the composite frame 2 and formed on the base membrane 1, the pressure-resistant particles 3 being evenly staggered in a semi-circular shape; and a microcapsule layer 4 composed of multiple layers located inside and above the composite frame 2, which, through the outer composite frame 2 and the inner pressure-resistant particles 3, serves to block large-area pressure, while simultaneously forming support within the microcapsule layer 4.
[0032] Among them, the microcapsule layer 4 consists of a bottom layer 41, a middle layer 42, and a top layer 43 from bottom to top. The self-healing composite microcapsule particle size in the middle layer 42 is larger than that in the bottom layer 41 and the middle layer 42. In this embodiment, through the layered arrangement of the microcapsule layer 4 and the support formed by the composite frame 2 and the pressure-resistant particles 3, the microcapsule layer 4 can more flexibly and reliably cope with different usage environment requirements and ensure the self-healing effect.
[0033] The bottom layer 41 is formed on the upper end of the base film 1 and located inside the composite frame 2. The thickness of the bottom layer 41 is less than the height of the pressure-resistant particles 3. In this embodiment, even if the inner side of the composite frame 2 is subjected to large area pressure, the pressure-resistant particles 3 can protect the bottom layer 41 and prevent the entire microcapsule layer 4 from being damaged. Even the middle layer 42 and the top layer 43 can still achieve self-repair effect by relying on the bottom layer 41, and the adaptation effect will be better.
[0034] The middle layer 42 is formed on the top of the bottom layer 41 and located inside the composite frame 2, and at least part of the bottom covers the pressure-resistant particles 3. In this embodiment, the middle layer 42 is the main repair layer. When the pressure is reached, it works simultaneously with the top layer 43, and can withstand large pressure indentations and can automatically repair itself.
[0035] The top layer 43 is formed on the upper surface of the middle layer 42 and the composite frame 2. The length and width of the top layer 43 are greater than those of the bottom layer 41 and the middle layer 42. In this embodiment, the top layer 43 is the highest priority repair layer and can self-repair small scratches, avoiding the complete failure of the self-repair function of this part due to light single indentation.
[0036] The top layer 43 is fitted with a protective layer 5 located on the top of the main body. In this embodiment, the protective layer 5 can be made of corrosion-resistant and wear-resistant materials, and also has functions such as anti-oxidation.
[0037] Among them, the pressure-resistant particle 3 is a polypropylene molding component. In this embodiment, polypropylene can ensure strength while ensuring transparency, thereby forming a front support inside the composite frame 2.
[0038] Understandably, by setting up multiple layers of microcapsules and then using composite frames and pressure-resistant particles to form internal and external support, the layering of microcapsule layers can be repaired layer by layer according to different pressures, thus increasing durability. The support of composite frames and pressure-resistant particles protects the microcapsule layers while ensuring the film properties, preventing large-area pressure from causing the entire microcapsule layer to fail, thus increasing flexibility.
[0039] A specific application of this embodiment is as follows: the base membrane 1 is made of polymer material, the composite frame 2 is formed of fiber and polymer material, and the pressure-resistant particles 3 are made of polypropylene material. They are solidified in the inner side of the composite frame 2 by dripping and located on the base membrane 1. A uniform small-particle-size self-healing microcapsule bottom layer 41 is filled between the base membrane 1 and the composite frame 2. The pressure-resistant particles 3 are at least partially covered by the bottom layer 41. After the bottom layer 41 is formed, a middle layer 42 composed of large-particle self-healing microcapsules is filled between its upper end and the inner side of the composite frame 2. The top height of the middle layer 42 is similar to that of the top of the composite frame 2. Then, a top layer 43 composed of small-particle-size particles is formed on the top surface of the middle layer 42 and the top surface of the composite frame 2. The top of the top layer 43 is kept flat. Then, a protective layer 5 is bonded to the flat top layer 43.
