Description

Technical Field

[0001] This utility model relates to the technical field of reflective material products, and in particular to a photoluminescent reflective fabric suitable for maritime applications. Background Technology

[0002] With increasing public awareness of safety, reflective materials are finding wider applications, especially in harsh environments like the sea, where their use is crucial for observation and search and rescue missions. Current reflective fabrics primarily utilize glass microspheres for reflection. For example, Chinese utility model patent CN214646584U discloses a light-storing and flame-retardant reflective fabric. This fabric achieves light storage and reflection by creating grooves on the surface of glass microspheres and filling them with light-storing material. However, in this design, the glass microspheres are semi-exposed. Especially in the high-temperature, high-humidity, and high-salt environment at sea, the microspheres are in direct contact with the external environment, making them prone to aging and detachment, leading to brightness reduction and affecting the performance of the reflective fabric. Improvements are needed to address this issue. Summary of the Invention

[0003] This invention addresses the shortcomings of existing reflective fabrics, such as the use of exposed glass microspheres, which makes them unsuitable for high-temperature, high-humidity, and high-salt environments like the sea, thus affecting the warning performance of the reflective fabric. It provides a new type of photoluminescent reflective fabric suitable for maritime applications.

[0004] To solve the above-mentioned technical problems, this utility model achieves this through the following technical solution:

[0005] A photoluminescent reflective fabric suitable for marine applications includes glass microspheres, a lower adhesive layer, a photoluminescent layer, and a base layer. The glass microspheres are bonded to the upper surface of the lower adhesive layer, and the photoluminescent layer is bonded between the lower surface of the lower adhesive layer and the upper surface of the base layer. The fabric also includes a protective layer located above the lower adhesive layer, which covers the glass microspheres. A portion of the protective layer is bonded to the lower adhesive layer and the photoluminescent layer, forming several embossed areas. Reflective areas are formed between adjacent embossed areas.

[0006] By setting embossed areas, different warning shapes can be formed on the photoluminescent reflective cloth, which improves the warning effect of the photoluminescent reflective cloth. The protective layer and the lower adhesive layer can provide all-round shielding and protection for the glass microspheres, which improves the stability of the glass microspheres fixed on the photoluminescent reflective cloth, making the photoluminescent reflective cloth suitable for high temperature, high humidity and high salt environment such as the sea surface.

[0007] Preferably, in the above-described photoluminescent reflective fabric suitable for marine applications, an air layer is formed between the lower surface of the protective layer and the upper surface of the lower adhesive layer, located within the reflective area, and the glass microspheres are located within the air layer.

[0008] An air layer is formed between the protective layer and the lower adhesive layer, above the glass microspheres. When the front of the photoluminescent reflective fabric is compressed, the air layer can rebound the protective layer, preventing the glass microspheres from being squeezed, thus further improving the protection effect of the glass microspheres.

[0009] Preferably, the above-described photoluminescent reflective fabric suitable for marine applications includes a protective layer comprising a surface layer and an upper adhesive layer, wherein the upper adhesive layer is bonded to the lower surface of the surface layer, and the upper adhesive layer and the lower adhesive layer are bonded to each other within the embossed area.

[0010] The protective layer has a double-layer structure, which further improves the protective effect of the protective layer on the glass microspheres. The upper adhesive layer allows the protective layer and the lower adhesive layer to adhere to each other, which further improves the adhesion and stability of the joint of the embossed area.

[0011] Preferably, in the above-described photoluminescent reflective fabric suitable for marine applications, the glass microspheres have a refractive index of 1.93.

[0012] Glass microspheres have a high refractive index, which further improves the reflective effect of the light-gathering reflective fabric.

[0013] Preferably, in the above-described photoluminescent reflective fabric suitable for marine applications, the photoluminescent layer is made of polyurethane, polyester, or acrylic resin, and the surface layer is made of polyurethane or acrylic resin.

[0014] The photoluminescent layer is made of polyurethane, polyester, or acrylic resin, and the surface layer is made of polyurethane or acrylic resin. It has the advantages of strong tear resistance, high temperature resistance, and high flame retardancy, which improves the adaptability of the photoluminescent reflective fabric to the marine environment.

[0015] Preferably, the photoluminescent reflective fabric suitable for marine applications described above has a base material of TC fabric, chemical fiber fabric, or aramid fabric.

[0016] The base material is TC cloth, chemical fiber cloth, or aramid cloth, which has the advantages of being wear-resistant, easy to clean, and wrinkle-resistant.

[0017] Preferably, the above-described photoluminescent reflective fabric suitable for marine applications further includes a composite layer, which is distributed between the photoluminescent layer and the base layer, and the photoluminescent layer and the base layer are bonded together by the composite layer.

[0018] The composite layer strengthens the adhesion between the base layer and the light-gathering layer, improving the stability of the connection between the light-gathering and reflective fabric layers. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-2 The present invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the present invention: Example

[0023] like Figure 1 , Figure 2 As shown, a photoluminescent reflective fabric suitable for marine applications includes glass microspheres 1, a lower adhesive layer 2, a photoluminescent layer 3, and a base layer 4. The glass microspheres 1 are bonded to the upper surface of the lower adhesive layer 2, and the photoluminescent layer 3 is bonded between the lower surface of the lower adhesive layer 2 and the upper surface of the base layer 4. It also includes a protective layer 5 located above the lower adhesive layer 2, which covers the glass microspheres 1. A portion of the protective layer 5 is bonded to the lower adhesive layer 2 and the photoluminescent layer 3, forming several embossed areas 6. Reflective areas 7 are formed between adjacent embossed areas 6.

[0024] Preferably, an air layer 71 is formed between the lower surface of the protective layer 5 and the upper surface of the lower adhesive layer 2, located within the reflective area 7, and the glass microspheres 1 are located within the air layer 71.

[0025] Preferably, the protective layer 5 includes a surface layer 51 and an upper adhesive layer 52. The upper adhesive layer 52 is bonded to the lower surface of the surface layer 51, and the upper adhesive layer 52 and the lower adhesive layer 2 in the embossed area 6 are bonded to each other.

[0026] Preferably, the glass microspheres 1 have a refractive index of 1.93.

[0027] Preferably, the light-gathering layer 3 is made of polyurethane, polyester, or acrylic resin, and the surface layer 51 is made of polyurethane or acrylic resin.

[0028] Preferably, the base layer 4 is made of TC fabric, chemical fiber fabric, or aramid fabric.

[0029] Preferably, a composite layer 8 is also included, which is distributed between the light-gathering layer 3 and the base layer 4, and the light-gathering layer 3 and the base layer 4 are bonded together by the composite layer 8.

[0030] Specifically, such as Figure 2As shown, the surface layer 51, upper adhesive layer 52, lower adhesive layer 2, light-gathering layer 3, composite layer 8, and fabric base layer 4 are placed in a top-to-bottom direction. The upper surface of the lower adhesive layer 2 is coated with a metal layer. The lower half of the glass microspheres 1 is embedded in the lower adhesive layer 2, and the metal layer covers the lower half of the glass microspheres 1. In this embodiment, the metal layer is made of aluminum, and the lower adhesive layer 2, upper adhesive layer 52, and composite layer 8 are made of polyurethane.

[0031] like Figure 1 , Figure 2 As shown, different shapes of embossed areas 6 can be used to obtain warning patterns or logos, thereby improving the warning effect of the photoluminescent reflective fabric. In this embodiment, the embossed area 6 is hexagonal.

[0032] Embossed areas 6 can be obtained through an embossing process. During the embossing operation, the phosphorescent layer 3, the lower adhesive layer 2, and the glass microspheres 1 are placed as a whole at the bottom, while the protective layer 5 is placed as a whole at the top. Simultaneously, the heated embossing roller causes a portion of the upper adhesive layer 52 to bond with the lower adhesive layer 2 and the phosphorescent layer 3, resulting in embossed areas 6 of different shapes. Finally, a composite layer 8 is coated on the lower surface of the phosphorescent layer 3 to bond with the base fabric 4, thereby improving the tear resistance of the phosphorescent reflective fabric and increasing its application range.

[0033] The glass microspheres 1 and photoluminescent particles 31 located in the embossed area are squeezed and move upward toward the adhesive layer 52, thereby distributing a number of glass microspheres 1 and photoluminescent particles 31 in the embossed area 6, making the photoluminescence effect clearly visible on the front of the photoluminescent reflective fabric. The protective layer 5 and the lower adhesive layer 2 located in the non-embossed area 6 are stretched to form an air layer 71 because they are not squeezed. Thus, when the front of the photoluminescent reflective fabric is compressed, the air layer 71 can rebound the protective layer 5, preventing the glass microspheres 1 from being squeezed. At the same time, the protective layer 5, the air layer 71, and the lower adhesive layer 2 can provide all-round protection for the glass microspheres 1, improving the weather resistance of the photoluminescent reflective fabric and making it suitable for high-temperature, high-salt, and high-humidity marine environments.

[0034] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
