Description
TECHNICAL FIELD

[0002] Insulating sheet refers to the sheet material with thin thickness that can prevent current from passing through. According to the different materials, the insulating sheet can be divided into various types, such as organic insulating sheet, inorganic insulating sheet and composite insulating sheet. Insulating sheet is an important material, which is widely used in electrical, electronic, mechanical and chemical fields. Insulating sheet can be used as insulating material for electronic equipment such as motor, transformer, switch, socket and cable, to ensure the safe operation of the equipment. Insulating sheet can be used for containers for storing and transporting chemicals such as chemical reactors, gas storage tanks, storage tanks and conveying pipelines, to prevent chemical leakage and corrosion. Insulating sheet can be used to manufacture mechanical seals, gaskets, bearing gaskets, soundproof materials and other mechanical equipment to improve the performance of the equipment.
[0003] Common insulating sheet is usually composed of base layer, coating layer and reinforcing structure. The base layer is usually composed of multiple layers of materials, and the base layer can be divided into upper layer, middle layer and lower layer, which can provide high strength and stable insulation performance. The coating layer is coated on the surface of the insulating sheet with one or more layers of coating with specific functions, such as anti-static coating, flame-retardant coating, etc., which not only provides additional protection, but also prevents the insulating sheet from being eroded by external environment, such as moisture, corrosion, etc. The reinforcing structure adds fibers, grids or other reinforcing materials to improve the mechanical strength and tear resistance of the insulating sheet.
[0004] Although the multi-layer structure of the conventional insulating material has higher insulation effect and mechanical strength, the multi-layer structure design causes the side edges of the insulating sheet to be easily worn or rolled off, thereby affecting the overall performance, leading to performance decline in high temperature, oxidation, wear and other environments, ultimately affecting the safety of electrical equipment. Therefore, a high-strength heat-resistant and wear-resistant insulating sheet is proposed. SUMMARY

The mounting groove 4 cooperates with the limiting buckle 5 to realize the limiting connection between the nylon wear-resistant edge 2 and the functional sheet layer 1. During work, the nylon wear-resistant edge 2 is pasted on the side of the functional sheet layer 1. At this time, the mounting grooves 4 on the upper surface and the lower surface of the nylon wear-resistant edge 2 clamp the four corners of the functional sheet layer 1. Then, the limiting buckle 5 is buckled in the mounting groove 4, so that the four corners of the functional sheet layer 1 are penetrated and effectively realize the limiting clamping effect, avoiding the occurrence of foot lifting between layers, and further avoiding the displacement and falling of the structure.
