[0025] To better understand the purpose, structure, and function of this utility model, a high-temperature resistant silicone sleeve of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] like Figure 1-3As shown, this utility model discloses a high-temperature resistant silicone sleeve, comprising an inner tube 3 made of nitrile rubber. Nitrile rubber is produced by low-temperature emulsion polymerization of butadiene and acrylonitrile, exhibiting good oil resistance (good resistance to fuel oil, lubricating oil, and aromatic solvents), excellent heat resistance, weather resistance, and chemical stability, superior ozone resistance, and high compression set resistance. Nitrile rubber also possesses high strength, high tear resistance, and excellent abrasion resistance. Furthermore, it exhibits good water resistance, airtightness, and excellent adhesion. A middle tube 2 is sleeved outside the inner tube 3, and an outer tube 1 is sleeved outside the middle tube 2. The outer tube 1 is made of neoprene rubber, exhibiting excellent resistance to ozone, ultraviolet radiation, weathering, and aging, with superior aging resistance, ultraviolet radiation resistance, low-temperature resistance, and abrasion resistance. Multiple slots 4 arranged in a circular array are provided on the outer surface of the middle tube 2 and the outer surface of the inner tube 3. Multiple locking strips 5 are provided on the inner wall of the outer tube 1 and the inner wall of the middle tube 2, which correspond one-to-one with the slots 4. The size of the locking strips 5 matches the size of the slots 4. Through the cooperation between the locking strips 5 and the slots 4, the middle tube 2, outer tube 1 and inner tube 3 are effectively limited, so that the middle tube 2, outer tube 1 and inner tube 3 will not slide freely between them, thus ensuring the stability of the structure.

[0027] The central tube 2 consists of a fiber tensile layer 6, a fabric winding layer 7, and a conductive copper wire layer 8, arranged sequentially from the inside out. To ensure the silicone sleeve can withstand the tensile forces during use, a mesh-structured polyester fabric is selected as the tensile skeleton layer, with a total of three layers wound around it. This fabric has high strength and elastic recovery capability, with the same fiber strength in both the longitudinal and transverse directions, making it sturdy and durable. The longitudinal fibers meet the requirements for longitudinal tensile strength. The selected polyester mesh fabric features high strength, good elasticity, strong corrosion resistance, good heat resistance, and good abrasion resistance. Furthermore, a flame-retardant structure is provided within the fabric wrapping layer 7. The flame-retardant structure includes flame-retardant strips 9 and flame-retardant cotton 10. A cavity is provided within the fabric wrapping layer 7, and the flame-retardant strips 9 are distributed in a circumferential array within the cavity. Flame-retardant cotton 10 is filled between each pair of adjacent flame-retardant strips 9. The inner cavity of the flame-retardant strips 9 is filled with flame-retardant powder. Through the cooperation between the flame-retardant strips 9 and the flame-retardant cotton 10, the flame-retardant performance of the silicone sleeve is greatly improved, giving the silicone sleeve good fireproof and heat insulation functions and strong safety.

[0028] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model.
