Description

Technical Field

[0001] This utility model relates to the field of PP sheet technology, specifically to a wear-resistant and antistatic PP sheet. Background Technology

[0002] PP sheets, also known as polypropylene sheets, are a semi-crystalline material. They are harder and have a higher melting point than PE. They are non-toxic and odorless, making them one of the most environmentally friendly engineering plastics. However, existing PP sheets are prone to generating static electricity due to friction during use, and cannot release it through their own conduction. They rely on external coatings or environmental humidity, resulting in insufficient reliability. In addition, their surface hardness is low, and long-term friction can easily cause scratches, fuzzing, or damage. Their performance degrades significantly, especially in high-load or rough contact surface scenarios. To solve these problems, a wear-resistant and anti-static PP sheet is needed.

[0003] Existing PP sheets have poor surface abrasion resistance, and are prone to scratches, fuzzing or damage due to long-term friction during use. They also have poor antistatic properties, and are prone to generating static electricity due to friction, which cannot be released through self-conduction and must rely on external coatings or environmental humidity, resulting in insufficient reliability. Therefore, there is an urgent need for a wear-resistant and antistatic PP sheet. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a wear-resistant and antistatic PP sheet to solve the problems of existing PP sheets, which have poor surface wear resistance, are prone to scratches, fuzzing or damage due to long-term friction during use, have poor antistatic performance, are prone to generating static electricity due to friction, and cannot release it through their own conduction, but need to rely on external coatings or environmental humidity, resulting in insufficient reliability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant and antistatic PP sheet, comprising a substrate, a structural groove formed on the inner wall of the substrate, a metal-carbon composite inner layer installed on the outer wall of the substrate, a wear-resistant composite surface layer installed on the outer wall of the metal-carbon composite inner layer, a wear-resistant frame installed on the outer wall of the wear-resistant composite surface layer, and a weight-reducing groove formed on the side wall of the wear-resistant frame.

[0006] Preferably, the structural groove is arranged in the form of an equilateral triangle, and the triangles inside the structural groove are arranged in an array with equal spacing.

[0007] Preferably, the metal-carbon composite inner layer is bonded to the substrate, and the metal-carbon composite inner layer is symmetrically arranged with the central axis of the substrate as the center.

[0008] Preferably, the wear-resistant composite surface layer is tightly bonded to the wear-resistant frame, and the outer peripheral corners of the wear-resistant frame are rounded.

[0009] Preferably, the wear-resistant frame is arranged in a rectangular array with the central axis of the substrate as the center, and the weight-reducing grooves are arranged at equal intervals with the central axis of the side wall of the wear-resistant frame as the center.

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

[0011] 1. This utility model features a substrate, structural grooves, and a metal-carbon composite inner layer. The structural grooves are formed by an array of equilateral triangles arranged at equal intervals. Triangles are the structure with the strongest geometric stability, and the rigid connection between their sides and corners can effectively resist deformation, suppress the overall bending of the substrate, and improve compressive rigidity. Meanwhile, the metal-carbon composite inner layer is made of copper powder, graphene, carbon black, and other materials, which can form a conductive network to conduct internal static electricity and achieve an antistatic effect.

[0012] 2. This utility model features a wear-resistant composite surface layer, a wear-resistant frame, and a weight-reducing groove. The wear-resistant composite surface layer is made of thermosetting resin material, with fillers such as silicon carbide and alumina added inside to further improve its wear resistance. It is used in conjunction with the wear-resistant frame to prevent the edges and corners of the board from being damaged by collisions. The weight-reducing groove reduces the overall weight and is highly practical. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The embodiments of this utility model will be described below based on its overall structure.

[0019] Please see Figures 1-3A wear-resistant and antistatic PP sheet includes a substrate 1. The inner wall of the substrate 1 has a structural groove 2, and the outer wall of the substrate 1 is fitted with a metal-carbon composite inner layer 3. The structural groove 2 is arranged in an equilateral triangle pattern, with the triangles within the structural groove 2 arranged in an equally spaced array. The metal-carbon composite inner layer 3 is bonded to the substrate 1 and is symmetrically arranged around the central axis of the substrate 1. The substrate 1, structural groove 2, and metal-carbon composite inner layer 3 are all connected. The structural groove 2 is formed by an equally spaced array of equilateral triangles. Triangles are the most geometrically stable structure, and the rigid connection of their sides and corners effectively resists deformation, suppressing the overall bending of the substrate 1 and improving compressive stiffness. Simultaneously, the metal-carbon composite inner layer 3 is composed of copper powder, graphene, carbon black, and other materials, forming a conductive network that conducts internal static electricity, achieving an antistatic effect.

[0020] Please see Figures 1-3 A wear-resistant and antistatic PP sheet is disclosed. A wear-resistant composite surface layer 4 is installed on the outer wall of a metal-carbon composite inner layer 3. A wear-resistant frame 5 is installed on the outer wall of the wear-resistant composite surface layer 4. Weight-reducing grooves 6 are provided on the side walls of the wear-resistant frame 5. The wear-resistant composite surface layer 4 and the wear-resistant frame 5 are tightly fitted together, and the outer perimeter corners of the wear-resistant frame 5 are rounded. The wear-resistant frame 5 is arranged in a rectangular array centered on the central axis of the substrate 1. The weight-reducing grooves 6 are evenly spaced centered on the central axis of the side walls of the wear-resistant frame 5. The wear-resistant composite surface layer 4 is made of thermosetting resin material, with fillers such as silicon carbide and alumina added to further enhance its wear resistance. It is used in conjunction with the wear-resistant frame 5 to prevent edge wear and collision. The weight-reducing grooves 6 reduce the overall weight, making it highly practical.

[0021] Working principle: In use, first move the device to the desired position, then tightly attach the wear-resistant frame 5 to the outer wall of the substrate 1 and bond it with adhesive. Meanwhile, the wear-resistant composite surface layer 4 is made of thermosetting resin material, with fillers such as silicon carbide and alumina added inside to further improve wear resistance. When used with the wear-resistant frame 5, it avoids collision and wear on the edges and corners of the board. The weight-reducing groove 6 reduces the overall weight and is highly practical. The structural groove 2 is formed by an array of equilateral triangles with equal spacing. Triangles are the structure with the strongest geometric stability. The rigid connection of its sides and corners can effectively resist deformation, suppress the overall bending of the substrate 1, and improve compressive rigidity. At the same time, the metal carbon composite inner layer 3 is made of copper powder, graphene, carbon black and other materials, which can form a conductive network to conduct internal static electricity and achieve an anti-static effect. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
