AI Technical Summary
Traditional PE waterproof coils are easily damaged when subjected to external impact pressure, resulting in poor waterproofing effect and affecting their service life.
A PE waterproof coil structure including a PE film layer, a base layer, an elastic cotton layer, a metal film layer, a braided mesh layer, a heat insulation layer and a fire-proof layer was designed. When the coil is impacted, the impact force is uniformly applied to the metal film layer through the braided mesh layer, combining the anti-compression bending of the metal film layer and the elastic deformation buffer of the elastic cotton layer to prevent the coil from being easily damaged at the metal film layer.
Through this structural design, the coil can maintain the integrity of the PE film after impact, significantly improve its mechanical strength, ensure waterproofing effect, and extend its service life. In addition, the added friction and divider lines further enhance the bonding strength and fire-resistant isolation performance.

[0006] By setting the above structure, when the coil where the PE film layer is located is subjected to external impact pressure as a whole, the impact force will first be pressed on the woven mesh layer. Due to the mesh characteristics of the woven mesh layer, the pressure at the woven mesh layer will be more evenly applied to the metal film layer. Combined with the metal film layer having certain metal compression bending and impact resistance and the elastic deformation buffering of the elastic cotton layer, the coil is not easily damaged at the metal film layer, which helps to ensure the integrity of the PE film layer after the impact, so that it has better mechanical strength, thereby ensuring the waterproof effect of the coil, thereby helping to ensure the long service life of the coil.
[0007] As a preferred implementation, a first friction pattern is provided on the metal film layer.
[0008] As a preferred implementation, the fireproof layer is provided with separation lines.
[0009] As a preferred implementation, the lower surface of the base layer is a bonding surface.
[0010] As a preferred implementation, a second friction pattern is provided on the bonding surface.
[0011] As a preferred implementation, the elastic cotton layer is mainly made of rock wool.
[0012] By providing the first friction pattern and the second friction pattern, the bonding area between the metal film layer and the bonding surface can be increased during bonding, which helps to make the bonding between the metal film layer and the bonding surface more firmly. By providing the dividing line pattern, the dividing line pattern can strengthen the fire isolation effect on the fireproof layer through the wire groove. By providing the main body of the elastic cotton layer with rock wool material, the coil has flame retardancy while having certain thermal insulation performance, which helps to ensure the overall waterproof and fireproof performance of the coil.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The utility model provides a metal film layer. When the coil where the PE film layer is located is subjected to external impact pressure as a whole, the impact force will first be pressed on the woven mesh layer.
