[0003] For example, the Chinese utility model patent with announcement number CN212124451U discloses a PE tarpaulin with multi-layer thermal insulation and moisture-proof functions. The PE tarpaulin with multi-layer thermal insulation and moisture-proof functions comprises a PE base fabric, wherein a first reinforcing layer and a second reinforcing layer are fixedly connected to the upper and lower end surfaces of the PE base fabric, respectively, and a thermal insulation layer is provided in the first reinforcing layer and the second reinforcing layer. The upper end of the first reinforcing layer is fixedly connected to a first waterproof layer, the upper end of the first waterproof layer is fixedly connected to a first sunshade layer, the lower end of the second reinforcing layer is fixedly connected to a second waterproof layer, and the lower end of the second waterproof layer is fixedly connected to a second sunshade layer. The PE tarpaulin with multi-layer thermal insulation and moisture-proof functions described in the utility model is connected by using the PE base fabric as the connection basis, and arranging the first reinforcing layer, the first waterproof layer, the first sunshade layer and the second reinforcing layer, the second waterproof layer and the second sunshade layer on the upper and lower parts of the PE base fabric respectively, so as to perform two-way thermal insulation and moisture-proofing on the PE base fabric, thereby improving the thermal insulation and moisture-proof effect.

[0004] When laying a PE tarpaulin, a rope is usually used to pass through the lock hole of the tarpaulin and then tighten it. However, during the tightening process, the rope is prone to slip back, causing the tarpaulin to sag. As a result, the tarpaulin swings greatly under the action of wind, making it unstable to use and causing some inconvenience. Therefore, a waterproof PE tarpaulin with a hydrophobic layer is proposed to solve the above problem. Utility Model Content
