Description

Technical Field

[0001] This utility model relates to the field of silicone heat shrink tubing, specifically to a smooth silicone heat shrink tubing. Background Technology

[0002] Silicone heat shrink tubing is a type of heat shrink sleeve made of silicone material, combining the excellent properties of silicone with the shrinkage characteristics of heat shrink tubing. It tightly wraps around the surface of the object being protected when heated, providing insulation, protection, and sealing. It is widely used in electronics, electrical engineering, aerospace, medical, and other fields. Silicone heat shrink tubing can typically be used continuously in a temperature range of -60℃ to 200℃, and some special products can even withstand higher temperatures.

[0003] Silicone heat shrink tubing is composed of a silicone substrate, heat shrink additives, and reinforcing materials. The silicone heat shrink tubing is placed on the surface of the object to be protected, and then heated using a heat gun, oven, or other heating equipment. This causes the silicone heat shrink tubing to gradually shrink due to the heat, ensuring that the silicone heat shrink tubing tightly wraps around the surface of the protected object without defects such as bubbles or wrinkles.

[0004] When using this silicone heat shrink tubing, the high surface friction coefficient makes it difficult to install or even break when fitting metal or plastic parts due to excessive resistance. Furthermore, existing silicone heat shrink tubing uses a single-layer silicone structure, resulting in a tight fit between the surface and the substrate after heat shrinking. However, disassembly requires external force to peel off the adhesive, which can easily damage the tubing or substrate. Additionally, existing silicone heat shrink tubing uses a slip agent to reduce friction, but the coating is prone to peeling and fails during high-temperature heat shrinking. Another solution uses a double-layer structure, but the poor bonding between the inner and outer layers leads to delamination and cracking after heat shrinking. Moreover, the lack of a coordinated design to address surface friction and tear resistance results in localized stress concentration during heat shrinking, causing uneven deformation and affecting sealing performance. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned defects by providing a silicone slip heat shrink tubing, which consists of an inner silicone base tube, a middle elastic support layer, and an outer slip layer. This solves the technical problems of reduced installation slip and tear resistance, as well as uneven heat shrinkage in the prior art.

[0006] The objective of this utility model is achieved through the following means:

[0007] A silicone slip heat shrink tubing includes an inner silicone base tube, with protrusions uniformly installed on the outer surface of the inner silicone base tube, an intermediate elastic support layer added to the outer surface of the inner silicone base tube, a reinforcing fiber braided layer connected to the outer surface of the intermediate elastic support layer, an outer slip layer added to the outer surface of the reinforcing fiber braided layer, a surface treatment layer connected to the outer surface of the outer slip layer, and a sleeve hole opened at the center of the top end of the inner silicone base tube. After the object to be protected is placed inside the sleeve hole, the tube is heated by a heating device, causing it to shrink and wrap around the surface of the object. The inner silicone base tube, protrusions, middle elastic support layer, reinforcing fiber braided layer, outer slip layer, and surface treatment layer can disperse heat shrinkage stress and maintain low adhesion at high temperatures. It is easy to peel off after heat shrinkage, avoiding adhesion and easy disassembly. At the same time, it can evenly shrink and deform the tube, avoid local stress concentration, and further improve the overall strength and durability of the heat shrink tubing. Especially when subjected to high pressure or tension, it can effectively disperse stress and prevent the heat shrink tubing from breaking. It can also effectively prevent moisture, oil, and other impurities from adhering to the surface of the heat shrink tubing, further improving the cleanliness and service life of the heat shrink tubing.

[0008] Furthermore, the protrusion is generally in a ring-shaped wave pattern, and there are nine sets of protrusions.

[0009] The inner silicone base tube has protrusions that optimize heat shrinkage uniformity.

[0010] Furthermore, the intermediate elastic support layer is composed of an elastic fiber mesh, with silicone particles embedded at the mesh nodes.

[0011] The intermediate elastic support layer disperses thermal shrinkage stress through the synergistic effect of elastic fiber mesh and silicone particles.

[0012] Furthermore, the inner wall of the outer slip layer is uniformly provided with hemispherical protrusions, and the hemispherical protrusions are fitted into the mesh of the elastic fiber web.

[0013] The hemispherical protrusions of the outer slip layer maintain low adhesion at high temperatures and are easy to peel off after heat shrinkage, thus preventing adhesion and facilitating disassembly, and inhibiting interlayer peeling.

[0014] Furthermore, the outer surface of the outer slip layer is provided with micro-protrusion guide patterns.

[0015] The outer slip layer, with its micro-protrusions and flow-guiding patterns, can balance the shrinkage and deformation of the tube body, avoiding localized stress concentration.

[0016] Furthermore, the surface treatment layer is a superhydrophobic coating.

[0017] The superhydrophobic coating has extremely low surface energy, which can effectively prevent moisture, oil and other impurities from adhering to the surface of the heat shrink tubing, further improving the cleanliness and service life of the heat shrink tubing. At the same time, the coating increases the wear resistance and anti-aging performance of the tubing to a certain extent.

[0018] The beneficial effects of this utility model are:

[0019] This solution involves placing the object to be protected inside the sleeve hole, then heating the tube using a heating device. The heated tube shrinks and wraps around the surface of the object. The tube consists of an inner silicone base tube, raised parts, a middle elastic support layer, a reinforcing fiber braided layer, an outer slip layer, and a surface treatment layer. This improves the smoothness of the tube installation, disperses heat shrinkage stress, maintains low adhesion at high temperatures, and is easy to peel off after heat shrinking, preventing adhesion and facilitating disassembly. It also evens out tube shrinkage deformation, preventing localized stress concentration and further improving the overall strength and durability of the heat shrink tubing. Especially under high pressure or tension, it effectively disperses stress, preventing the heat shrink tubing from breaking. Furthermore, it effectively prevents moisture, oil, and other impurities from adhering to the surface of the heat shrink tubing, further improving its cleanliness and service life.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] In this embodiment, refer to Figures 1-6 A specific embodiment of the silicone slip heat shrink tubing includes a tubing body 1, the tubing body 1 including an inner silicone base tube 6, the outer surface of the inner silicone base tube 6 being uniformly provided with protrusions 8, the outer surface of the inner silicone base tube 6 being provided with an intermediate elastic support layer 5, the outer surface of the intermediate elastic support layer 5 being connected with a reinforcing fiber braided layer 4, the outer surface of the reinforcing fiber braided layer 4 being provided with an outer slip layer 3, the outer surface of the outer slip layer 3 being connected with a surface treatment layer 2, and a sleeve hole 7 being opened at the center of the top end of the inner silicone base tube 6. After the object to be protected is placed inside the sleeve hole 7, the tube body 1 is heated by a heating device, causing the tube body 1 to shrink and wrap around the surface of the object to be protected. The inner silicone base tube 6, the protrusions 8, the middle elastic support layer 5, the reinforcing fiber braided layer 4, the outer slip layer 3, and the surface treatment layer 2 can disperse the heat shrinkage stress and maintain low adhesion at high temperatures. After heat shrinkage, it is easy to peel off, avoiding adhesion and easy disassembly. At the same time, it can evenly distribute the shrinkage deformation of the tube body 1, avoid local stress concentration, and further improve the overall strength and durability of the heat shrink tube. Especially when subjected to high pressure or tension, it can effectively disperse stress and prevent the heat shrink tube from breaking. At the same time, it can effectively prevent moisture, oil and other impurities from adhering to the surface of the heat shrink tube, further improving the cleanliness and service life of the heat shrink tube.

[0029] like Figure 5 , Figure 6 As shown, the protrusion 8 is generally in a ring-shaped wave pattern, and there are nine sets of protrusions 8. The inner silicone base tube 6 can optimize the uniformity of heat shrinkage through the protrusions 8.

[0030] like Figure 4 As shown, the intermediate elastic support layer 5 is composed of an elastic fiber mesh, with silicone particles embedded at the mesh nodes. The intermediate elastic support layer 5 disperses thermal shrinkage stress through the synergistic effect of the elastic fiber mesh and silicone particles.

[0031] like Figure 3 As shown, the inner wall of the outer slip layer 3 is uniformly provided with hemispherical protrusions, which are interlocked with the mesh of the elastic fiber network. The hemispherical protrusions of the outer slip layer 3 maintain low adhesion at high temperatures and are easily peeled off after heat shrinkage, thus preventing adhesion and facilitating disassembly, and inhibiting interlayer delamination. The outer surface of the outer slip layer 3 is provided with micro-protrusion guiding patterns. These micro-protrusion guiding patterns help to balance the shrinkage deformation of the tube body 1, preventing localized stress concentration.

[0032] like Figure 1As shown, surface treatment layer 2 is a superhydrophobic coating. The superhydrophobic coating has extremely low surface energy, which can effectively prevent moisture, oil and other impurities from adhering to the surface of the heat shrink tubing, further improving the cleanliness and service life of the heat shrink tubing. At the same time, the coating increases the wear resistance and anti-aging performance of the tubing body 1 to a certain extent.

[0033] The hair curling process of a silicone smooth heat shrink tubing in this embodiment is as follows: After the object to be protected is placed inside the sleeve hole 7, the tubing 1 is heated by a heating device, so that the tubing 1 shrinks and wraps around the surface of the object to be protected.
