Description

Technical Field

[0001] This utility model relates to the field of pearl cotton technology, specifically a flame-retardant and waterproof pearl cotton structure. Background Technology

[0002] Pearl cotton, also known as EPE pearl cotton, is a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles generated by the physical foaming of low-density polyethylene resin. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat insulation, good plasticity, high toughness, recyclability, environmental protection, and strong impact resistance. It also has good chemical resistance, making it an ideal choice for packaging materials.

[0003] Existing EPE foam can only withstand temperatures up to around 120℃; above this temperature, it melts and decomposes. Furthermore, current EPE foam is typically a single layer, making it susceptible to burning through at high temperatures, thus failing to effectively protect the packaged goods. Therefore, we propose a flame-retardant and waterproof EPE foam structure. Utility Model Content

[0004] To address the shortcomings of existing pearl cotton in resisting high temperatures, this invention provides a flame-retardant and waterproof pearl cotton structure, which features a heat insulation layer and a fire-retardant layer between two layers of pearl cotton. The heat insulation layer and the fire-retardant layer can effectively block high temperatures, thereby protecting the packaged items and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a flame-retardant and waterproof pearl cotton structure is designed, including a first pearl cotton layer and a second pearl cotton layer. This application also includes an intermediate layer, which includes a heat insulation layer. Fire-resistant layers are respectively provided on both sides of the heat insulation layer. A tensile layer is provided on the surface of at least one fire-resistant layer. The tensile layer is a mesh cloth or a metal mesh. The intermediate layer is located between the first pearl cotton layer and the second pearl cotton layer, and the first pearl cotton layer and the second pearl cotton layer are respectively connected to the fire-resistant layer.

[0006] Preferably, the fire-retardant layer is a metal foil or a flame-retardant coating disposed on the surface of the heat insulation layer.

[0007] Preferably, the heat insulation layer is fireproof cloth or fireproof cotton.

[0008] Preferably, both the first and second pearl cotton layers have a flame-retardant coating.

[0009] Preferably, the surfaces of the first and second pearl cotton layers are further provided with a hydrophobic coating, which is located on the surface of the flame-retardant coating.

[0010] Compared with the prior art, the flame-retardant and waterproof pearl cotton structure proposed in this application has a first pearl cotton layer, an intermediate layer and a second pearl cotton layer. It has a multi-layer structure, which improves its heat insulation performance and protection performance for goods. Most importantly, when the outermost pearl cotton melts at high temperature, the fire-retardant layer and heat insulation layer in the intermediate layer can effectively prevent the high temperature from being transmitted to the innermost pearl cotton, thereby protecting the goods from the effects of temperature.

[0014] 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.

[0015] Please see Figures 1 to 2 This utility model provides a technical solution: a flame-retardant and waterproof pearl cotton structure, including a first pearl cotton layer 1 and a second pearl cotton layer 5, both of which are pearl cotton, and an intermediate layer is provided between the first pearl cotton layer 1 and the second pearl cotton layer 5, which is used for waterproofing and flame retardancy.

[0016] The specific flame-retardant process is as follows: Figure 2 As indicated by the middle arrow, assuming the external heat source is located outside the first pearl cotton layer 1, the packaged item must be located on the second pearl cotton layer 5. The heat emitted by the heat source will be directly transferred to the surface of the first pearl cotton layer 1. Pearl cotton has a temperature tolerance between -50℃ and 120℃, so it has a certain high-temperature resistance. When the temperature exceeds the maximum temperature tolerance of pearl cotton, it begins to decompose, and the high temperature at this time will directly affect the intermediate layer. Therefore, the intermediate layer proposed in this application must not only have a flame-retardant effect but also have the function of heat insulation to protect the item located on the second pearl cotton layer 5.

[0017] like Figure 1 As shown, the intermediate layer specifically includes a heat insulation layer 3, and fire-resistant layers 2 are provided on both sides of the heat insulation layer 3.

[0018] The insulation layer 3 is made of fireproof cloth or fireproof cotton. Examples of fireproof cloth include high-silica fireproof cloth, fiberglass-coated flame-retardant cloth, silicone fabric, and SM fireproof cloth. Examples of fireproof cotton include aluminum silicate fireproof cotton, calcium silicate fireproof cotton, ceramic fiber fireproof cotton, silicon carbide fiber fireproof cotton, and asbestos. In practical applications, the choice between fireproof cloth and fireproof cotton depends on the specific circumstances. Fireproof cloth has slightly poorer insulation properties, while fireproof cotton can block higher temperatures.

[0019] The fire-retardant layer 2 is a metal foil or a flame-retardant coating. Metal foils include copper foil and aluminum foil, while flame-retardant coatings include aerogel flame-retardant layers or acrylic flame-retardant conformal coatings. For example... Figure 2 As shown, after the temperature melts the outermost first pearl cotton layer 1, its temperature directly acts on the fire-resistant layer 2. Since the fire-resistant layer 2 consists of two layers, with a heat insulation layer 3 separating them, the fire-resistant layer 2, which directly faces the high temperature, can prevent the high temperature from being transferred to the heat insulation layer 3. At the same time, the heat insulation layer 3 can further prevent heat from being transferred to the fire-resistant layer 2, which is further away from the high temperature. Therefore, when the heat is transferred to the second pearl cotton layer 5, the temperature will be greatly reduced. In practical applications, the protected goods are located on one side of the second pearl cotton layer 5. The above structure protects the second pearl cotton layer 5 from the high temperature to the greatest extent, thereby protecting the goods located on one side of the second pearl cotton layer 5.

[0020] Since high temperatures can cause materials to deform, a tensile layer 4 is provided on the surface of at least one fire-resistant layer 2 to prevent material deformation. The tensile layer 4 is a mesh or metal mesh, and the mesh can be a fiberglass mesh. When the tensile layer 4 is a single layer, it is placed on the surface of the fire-resistant layer 2 away from the high temperature, so as to avoid direct baking by the high temperature. When the fire-resistant layer 2 is subjected to high temperature, the heat insulation layer 3 and the fire-resistant layer 2 can prevent deformation under the support of the mesh, thus improving the deformation resistance effect.

[0021] In actual use, the first pearl cotton layer 1, the second pearl cotton layer 5 and the intermediate layer, as well as the fire-resistant layer 2, the heat insulation layer 3 and the tensile layer 4 in the intermediate layer are bonded together with glue to connect multiple structures into a whole.

[0022] Furthermore, in order to further improve the flame retardancy, a flame retardant coating is provided on the surface of both the first pearl cotton layer 1 and the second pearl cotton layer 5. This flame retardant coating can directly contact the heat source, thereby protecting the outermost pearl cotton layer.

[0023] Furthermore, it should be noted that the pearl cotton layer itself is impermeable to water, and the first pearl cotton layer 1, the second pearl cotton layer 5 and the intermediate layer are tightly connected, so external moisture will not enter its interior. However, in order to stick water droplets on the surface, a hydrophobic coating is also provided on the surface of the first pearl cotton layer 1 and the second pearl cotton layer 5. The hydrophobic coating is located on the surface of the flame retardant coating, which can prevent water droplets from sticking to the surface of the pearl cotton.
