Description

Technical Field

[0001] This utility model relates to the technical field of plastic sheets, and in particular to a multi-layer composite PE plastic sheet. Background Technology

[0002] Plastic sheets are sheets made from plastic raw materials, primarily high-molecular polymers (or synthetic resins), and may contain fillers, plasticizers, lubricants, stabilizers, colorants, and other auxiliary materials to improve their performance. Plastic sheets are characterized by high practicality and the ability to be freely shaped. Due to their corrosion resistance, aging resistance, water resistance, moisture resistance, wear resistance, and high strength, plastic sheets are widely used in construction engineering, machinery industry, chemical industry, and other fields. For example, plastic-metal composite panels are suitable for nano- and micro-processing; rigid PVC building panels are commonly used for ceilings and wall panels; polypropylene plastic sheets are suitable for ventilation ducts; polyethylene plastic sheets are used for welding and medical devices; and ABS plastic sheets are suitable for various industrial and civil applications.

[0003] After extensive searching, a Chinese patent announcement number CN208566146U was found, which discloses a decorative structure for a plastic sheet, including a plastic sheet with a hardening coating. The hardening coating is a mixed coating of hardening, anti-glare, and anti-fingerprint properties. The plastic sheet can be any one of PC, PMMA, PET, ABS, PVC, or fiberglass board. The decorative structure also includes a first bottom layer, a second bottom layer, and a third bottom layer. The hardening coating, the plastic sheet, the first bottom layer, the second bottom layer, and the third bottom layer are stacked from top to bottom. The first bottom layer is a digital printing inkjet layer, the second bottom layer is a pearl ink screen printing layer, and the third bottom layer is a screen-printed cover layer.

[0004] In summary, in existing plastic sheets, the sheets are generally installed together by interlocking structures, but the stability during installation is relatively poor.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a multi-layer composite PE plastic sheet, which would have greater industrial application value. Utility Model Content

[0017] By means of the above solution, this utility model has at least the following advantages:

[0018] This utility model features a structure in which a first splicing block, a second splicing block, and a connecting rod are installed together. This structure is simple to install and can improve the firmness of the plate installation.
