Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The cable protection tube according to an embodiment shown in fig. 1 includes an inner mesh tube 10 and a protection outer tube 20 sleeved outside the inner mesh tube 10, wherein the meshes of the inner mesh tube 10 are filled with cured glue 12, and the cured glue 12 glues the inner mesh tube 10 and the protection outer tube 20 together.

The mesh of the inner layer mesh tube 10 of the cable protection tube is filled with the solidified glue 12, the solidified glue 12 glues the inner layer mesh tube 10 and the protection outer tube 20 together, and therefore the bonding force between the inner layer mesh tube 10 and the protection outer tube 20 is improved, and compared with the traditional tube, the bonding force between the inner layer mesh tube 10 and the protection outer tube 20 of the cable protection tube is strong.

Generally, the inner mesh tube 10 may be a woven mesh tube or a crocheted mesh tube.

Specifically, the inner mesh tube 10 may be a conductive mesh tube or an insulating mesh tube.

In one particular embodiment, the inner mesh tube 10 is a conductive mesh tube formed by conductive spun weaving or crocheting.

In this embodiment, the conductive spun yarn is spun yarn coated with a conductive layer on the outer periphery.

Particularly preferably, the conductive spun yarn is tinned copper wire (T1 red copper, copper content is over 99.9%), and in this case, the inner mesh tube 10 is a tinned copper mesh tube.

Specifically, the tinned copper wire has excellent conductivity and oxidation resistance.

In this embodiment, the cable protection tube can be used to manufacture connecting wires or grounding wires with different specifications or extra-high current capacity by utilizing the high conductivity, flexibility and good heat dissipation of the tin-plated copper, and can be used in a diversified manufacturing method to manufacture shielding products with various structures and excellent shielding effectiveness.

After the protective layer is matched, the cable protective tube is coated by functional materials, so that the performances of water resistance, voltage resistance, impact resistance and the like of the product are improved.

In another specific embodiment, the inner mesh tube 10 may be an insulating mesh tube formed by non-conductive spinning weaving or crocheting, and the non-conductive spinning is PET spinning, PA spinning, PP spinning or PE spinning.

In this embodiment, when the non-conductive spun yarn is PET spun yarn, the inner mesh tube 10 is a PET mesh tube. The PET spinning material is as follows: 95 wt% of polyester chips, 4 wt% of JDD modified granulation flame-retardant master batch and 1 wt% of color master batch.

The PET net pipe has ultrahigh temperature resistance, can pass through a 175 ℃/504H test without brittle fracture (the common monofilament net pipe can only pass through 150 ℃/504H)

The PET net pipe has excellent flame retardant performance, and can achieve self-extinguishing when the PET net pipe is away from fire and dropping of non-combustible cotton (common PET monofilament net pipes on the market can achieve self-extinguishing, but dropping of non-combustible cotton).

The PET net pipe has good wear resistance, and the wear resistance times can reach more than 1 ten thousand times by using an ISO6722-1 test method (the number of common monofilaments in the market is 2000-3000 times).

The PET mesh tube has good chemical agent resistance.

The PET net pipe can simultaneously meet the requirements of working in different severe environments, such as high-temperature and high-humidity environments, environments with contact interference, weak-acid environments and the like.

After the protective layer is matched, the cable protective tube is coated by functional materials, so that the performances of water resistance, voltage resistance, impact resistance and the like of the product are improved.

In the present embodiment, the protective outer tube 20 is a thermoplastic protective outer tube.

The protective outer tube 20 is a thermoplastic protective outer tube to facilitate the production of the cable protective tube.

When the cable protection tube is actually produced, the inner layer mesh tube 10 is firstly soaked in glue, and then the inner layer mesh tube 10 soaked in the glue is coated with a thermoplastic protection layer through an extruder.

Specifically, the protective outer tube 20 may be a PVC tube, a silicone tube, a TPE tube, a PE tube, or a hot melt tube.

The glue is used for improving the adhesion of the pipe.

In this embodiment, the glue is a water-soluble glue. In the present embodiment, the water-soluble glue is generally a highly chemically active glue containing no additives containing chemical components such as magnesium, phosphorus, aluminum, and iron, and containing no carbon or a material having a low carbon content as a main component.

Preferably, the water-soluble glue comprises: 20 to 95 parts of main body, 0 to 3 parts of defoaming agent, 0 to 5 parts of additive and 5 to 80 parts of water.

Specifically, the main body is selected from at least one of talc, silica, white latex, and sodium silicate.

Specifically, the additive is selected from at least one of a leveling agent, an emulsifier, a thickener, and a post-crosslinking agent.

Preferably, the cable protection tube may further include a glue layer between the inner mesh tube 10 and the protective outer tube 20, so that the coupling force between the inner mesh tube 10 and the protective outer tube 20 may be further enhanced.

By controlling the extrusion process of the extruder, the glue content of the inner mesh tube 10 soaked with glue can be controlled, when the glue content is low, a glue layer cannot be formed, and when the glue content is high, a glue layer is formed between the inner mesh tube 10 and the protective outer tube 20.
