When using the pearl cotton structure for packaging, in order to make the pearl cotton structure fit better with the items, the pearl cotton needs to have good toughness.

[0003] At present, the existing pearl cotton structure lacks a certain toughness structure, and the toughness of the pearl cotton is not high, which leads to the poor plasticity of the pearl cotton. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an EPE coil with a protective coating inside, which effectively solves the problem that the current EPE has low toughness and is prone to tearing.

[0005] To achieve the above object, the utility model provides the following technical solution: a pearl cotton coil with a protective coating inside, comprising a first pearl cotton, an outer protective layer bonded to the top of the first pearl cotton, a second pearl cotton is provided below the first pearl cotton, an inner protective coating is bonded to the bottom of the second pearl cotton, and a reinforcing mechanism is installed between the first pearl cotton and the second pearl cotton;

[0006] The reinforcing mechanism comprises an elastic strip 1 equidistantly located between the first pearl cotton and the second pearl cotton, a reinforcing groove is arranged on the side where the first pearl cotton and the second pearl cotton are close to each other, and both sides of the elastic strip 1 are respectively located in the two reinforcing grooves.

[0007] Preferably, two adjacent elastic strips 1 are symmetrically fixedly connected with each other.

[0008] Preferably, elastic balls are provided at equal distances between two adjacent elastic strips 1, reinforcing rod 1 is fixedly connected between the two elastic strips 1 and the elastic balls, and reinforcing rod 2 is fixedly connected between the first pearl cotton and the second pearl cotton and the elastic balls.

[0009] Preferably, the outer protective layer is a waterproof membrane, and the inner protective coating is made of a polymer-based composite material.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] (1) The utility model connects the first pearl cotton with the second pearl cotton through the cooperation between the elastic strip 1 and the second elastic strip and the reinforcing groove, and improves the strength of the entire pearl cotton through the cooperation between the elastic ball and the reinforcing rod 1 and the second reinforcing rod. At the same time, the elastic strip 1 and the second elastic strip and the elastic ball are elastic, so as to improve the toughness of the entire pearl cotton and avoid tearing;

[0012] (2) The new type achieves a waterproof effect by bonding an outer protective layer on the top of the first pearl cotton, and bonding an inner protective coating on the bottom of the second pearl cotton, and the inner protective coating is made of a polymer-based composite material, thereby facilitating the improvement of the moisture-proof, corrosion-resistant and oxidation-resistant properties of the entire pearl cotton coil.
