Description

Technical Field

[0001] This utility model relates to the field of foam board technology, specifically to a PS foam board with ultra-low density. Background Technology

[0002] PS foam board is a product made from polystyrene granules through secondary foaming. Many people are not very familiar with it, but basically 90% of people have used it. Fast food boxes in daily life are mostly made from PS foam sheets through a second molding process. The only difference between PS foam board and domestic KT board is that PS foam board does not have a lamination. In the advertising and packaging industries, it is also called pearl board. However, existing PS foam boards have relatively low structural strength and poor density.

[0003] Therefore, in view of this, we studied and improved the existing structure to propose a PS foam board with ultra-low density effect. Utility Model Content

[0004] The purpose of this invention is to provide a PS foam board with ultra-low density to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PS foam board with ultra-low density effect, comprising a foam board body, wherein a casting cavity is formed on the upper surface and the lower surface of the foam board body, and a cavity is provided inside the foam board body, and a composite board is provided inside the cavity. Several elastic plates are fixedly connected to the outer surface of the composite board, and the composite board is designed with several triangular holes, which are combined to form a honeycomb shape.

[0006] Preferably, the inner surface of the casting cavity is fixedly connected with a plurality of reinforcing ribs, and the reinforcing ribs form a triangular structure.

[0007] Preferably, the reinforcing rib has a through-hole, and the through-hole is evenly distributed on the surface of the reinforcing rib.

[0008] Preferably, the front surface of the foam board body has an injection port on the upper side, and there are two injection ports, which are symmetrically designed.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model, through the setting of foam board body, casting cavity, composite board and elastic board, the composite board is made of ultra-low density board, the elastic board can improve the impact resistance and deformation capability of the foam board body. When the foam board body is subjected to external impact or compression, the elastic board can improve the recovery capability, preventing the foam board body from being unable to return to its original position after being subjected to external force, causing irreversible damage and affecting appearance and performance;

[0011] 2. By setting up reinforcing ribs, flow holes, and injection ports, the reinforcing ribs can achieve the original structural strength as much as possible after the casting cavity is opened. Cement mortar is poured into the interior of the foam board body through the injection port to achieve higher structural strength. At the same time, the triangular structure formed by the reinforcing ribs can further enhance the structural strength. Attached Figure Description

[0017] 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.

[0018] like Figures 1-4 As shown, a PS foam board with ultra-low density effect includes a foam board body 1. A casting cavity 2 is opened on the upper surface and the lower surface of the foam board body 1. A cavity is provided inside the foam board body 1, and a composite board 3 is provided inside the cavity. Several elastic plates 4 are fixedly connected to the outer surface of the composite board 3. The composite board 3 is designed with several triangular holes, and the triangles are combined to form a honeycomb shape.

[0019] By adopting the above technical solution, the composite board 3 is made of ultra-low density board, and the elastic board 4 can improve the impact resistance and deformation capability of the foam board body 1. When the foam board body 1 is subjected to external impact or compression, the elastic board 4 can improve the recovery capability, preventing the foam board body 1 from being unable to return to its original position after being subjected to external force, causing irreversible damage and affecting appearance and performance.

[0020] like Figures 1-2 As shown, several reinforcing ribs 5 are fixedly connected to the inner surface of the casting cavity 2, and the reinforcing ribs 5 form a triangular structure.

[0021] Furthermore, the interior of the reinforcing rib 5 is provided with a flow hole 6, and the flow holes 6 are evenly distributed on the surface of the reinforcing rib 5.

[0022] Furthermore, an injection port 7 is provided on the upper side of the front surface of the foam board body 1, and there are two injection ports 7, which are symmetrically designed.

[0023] Working principle: When using this PS foam board with ultra-low density effect, firstly, the composite board 3 is made of ultra-low density board. The elastic board 4 can improve the impact resistance and deformation ability of the foam board body 1. When the foam board body 1 is subjected to external impact or compression, the elastic board 4 can improve the restoring ability and prevent the foam board body 1 from failing to return to its original position after being subjected to external force. The reinforcing rib 5 can achieve the original structural strength as much as possible after opening the pouring cavity 2. Cement mortar is poured into the interior of the foam board body 1 through the injection port 7 to achieve higher structural strength. At the same time, the triangular structure formed by the reinforcing rib 5 can also further enhance the structural strength. This is the working principle of the PS foam board with ultra-low density effect.
