[0002] EPE, namely polyethylene foam, is a new type of environmentally friendly packaging material and a non-crosslinked closed-cell structure.
[0003] When the existing EPE is in use, since it is often used for packaging objects, during the process of packaging, placing and transporting, it is extremely easy to be squeezed. Although the EPE itself has a certain toughness, the directions of squeezing are diverse, and it is not easy for the EPE itself to support pressures from various angles, having certain limitations in support. Moreover, the EPE is prone to deformation due to squeezing, and thus is likely to cause a large extrusion force on the wrapped object, reducing the safety of wrapping the object. Therefore, in order to solve the above problems, a multi-layer EPE is proposed herein. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] The present utility model provides as Figure 1-2A multi-layered pearl cotton as shown includes a pearl cotton main body 1. The pearl cotton main body 1 includes two pearl cotton substrate layers 101, a protection component, and a heat preservation component. The two pearl cotton substrate layers 101 are both fixedly arranged between multiple compression layers 201. The protection component is arranged above the pearl cotton substrate layer 101, and the heat preservation component is arranged below the pearl cotton substrate layer 101. The protection component includes an antistatic layer 102 and a waterproof layer 103. The antistatic layer 102 is fixedly arranged between one of the compression layers 201 and the waterproof layer 103, and the waterproof layer 103 is arranged above one of the compression layers 201. The heat preservation component includes an adhesive layer 104 and a heat preservation layer 105. The adhesive layer 104 is fixedly arranged between the heat preservation layer 105 and the other compression layer 201, and the heat preservation layer 105 is arranged below the other compression layer 201.
[0020] As Figure 1 and Figure 2 shown in, the antistatic layer 102 is an antistatic silver fiber, which can release negative charges and neutralize the positive charges on the surface of the pearl cotton main body 1, thereby reducing the generation of static electricity on the surface of the pearl cotton main body 1, and then effectively improving the antistatic performance of the pearl cotton main body 1, reducing the adhesion of dust on the end face of the pearl cotton main body 1, and improving the cleanliness of the pearl cotton main body 1 during use. The waterproof layer 103 is a polyurethane waterproof coating, which is coated on the surface of the pearl cotton main body 1 to increase the waterproof performance of the pearl cotton main body 1, so that when the pearl cotton main body 1 is used, it can avoid easily generating a humid phenomenon, thereby better protecting the object wrapped by the pearl cotton main body 1 and effectively improving the safety of the pearl cotton main body 1 during use. The adhesive layer 104 is an EPE pearl cotton glue, and the adhesive layer 104 is also evenly coated on the opposite end faces of the antistatic layer 102 and one of the compression layers 201, so that the antistatic layer 102, the compression layer 201, the heat preservation layer 105, and the other compression layer 201 are adhered to each other, effectively strengthening the stability of the connection between the antistatic layer 102, the heat preservation layer 105, and the compression layer 201. The heat preservation layer 105 is glass wool, which has good heat preservation effect and can increase the heat preservation performance of the pearl cotton main body 1. When the pearl cotton main body 1 is used, it can play an excellent heat preservation effect on the object wrapped, expanding the applicable range of the pearl cotton main body 1 and improving the effectiveness and use value of the pearl cotton main body 1.
[0021] A compression structure 2 is arranged inside the pearl cotton main body 1. The compression structure 2 includes multiple compression layers 201 and multiple compression fibers 202. The multiple compression layers 201 are symmetrically arranged inside the pearl cotton main body 1, and the multiple compression fibers 202 are respectively fixedly arranged in the inner cavities of the multiple compression layers 201. The multiple compression fibers 202 are all used for the restoration of the shape of the pearl cotton main body 1 after being compressed.
[0022] As Figure 2As shown in the figure, the compressive layers 201 are respectively arranged at the upper and lower positions of the EPE substrate layer 101, so that the compressive performance inside the EPE main body 1 is relatively uniform. The compressive layer 201 is composed of a plurality of compressive fibers 202. The compressive fiber 202 is any one of polyurethane fibers or diene-based elastic fibers, and has good elastic support performance. The compressive fibers 202 are all in a cross shape, suitable for a variety of stretching and extrusion. When the EPE main body 1 is in use and is in a state of being squeezed or stretched, it can utilize the elastic deformation performance of the compressive fibers 202 to play a certain supporting role, so as to avoid causing a large pressure on the object wrapped by the EPE main body 1, and play an excellent protective role for the object wrapped by the EPE main body 1, improving the protective performance of the EPE main body 1 during use. At the same time, the compressive fibers 202 can utilize the space of the compressive layer 201 to exert a greater degree of elastic deformation, so as to increase the compression range of the EPE main body 1. Furthermore, after the EPE main body 1 is compressed, it can utilize the elastic performance of the compressive fibers 202 to restore its shape, providing effective support for the multiple uses of the EPE main body 1 and improving the reuse rate of the EPE main body 1.
[0023] A limiting structure 3 is arranged on the outer wall of the EPE main body 1. The limiting structure 3 includes a limiting block 301 and a limiting groove 302. The limiting block 301 is fixedly arranged at the top of the EPE main body 1, and the limiting groove 302 is opened at the bottom of the EPE main body 1. The limiting block 301 and the limiting groove 302 are used to limit the connection position between multiple EPE main bodies 1. The limiting structure 3 further includes a positioning block 303 and a positioning groove 304. The positioning block 303 is fixedly arranged on the side of the limiting block 301, and the positioning groove 304 is opened on the side of the inner cavity of the limiting groove 302. The positioning block 303 and the positioning groove 304 are used to limit the position after the limiting block 301 and the limiting groove 302 are connected.
[0024] As Figure 1 and Figure 2As shown in the figure, the limiting block 301 and the limiting groove 302 are respectively arranged at the top and bottom of the EPE main body 1. When multiple EPE main bodies 1 need to be stacked, the limiting block 301 and the limiting groove 302 can be used for position limitation through interpenetrating and fitting, so as to facilitate the connection between multiple EPE main bodies 1, and further facilitate improving the stability and safety of the stacked placement of multiple EPE main bodies 1. The positioning block 303 is any one of elastic rubber or elastic silica gel, and has good elastic deformation performance. When the limiting block 301 penetrates into the inner cavity of the limiting groove 302, the compressed positioning block 303 will generate elastic deformation under extrusion, so as to ensure the interpenetrating connection between the limiting block 301 and the inner cavity of the limiting groove 302. When the limiting block 301 and the inner cavity of the limiting groove 302 are fitted, the positioning block 303 will also penetrate and connect with the inner cavity of the corresponding positioning groove 304, so as to strengthen the firmness of the connection between the limiting block 301 and the limiting groove 302, and further facilitate improving the firmness and safety of the position connection between multiple EPE main bodies 1.
