Description

Technical Field

[0001] This invention relates to the field of reinforcing core technology, and in particular to a high-strength and tough reinforcing core and its manufacturing process. Background Technology

[0002] With the rapid development of society, people are becoming increasingly reliant on communication networks and information transmission. Communication networks are developing towards higher capacity and density. Once damaged, they will immediately cause serious economic losses and inconvenience to our lives. Therefore, certain measures should be taken to protect optical cables and improve them to ensure the long-term smooth operation and reliability of communication networks.

[0003] Existing reinforcing cores use composite inner cores to increase tensile and impact resistance. However, this method makes the inner core prone to damage during bending and stretching, and it cannot be repaired, posing a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a high-strength and tough reinforcing core and its manufacturing process. By setting an anti-tensile layer on the inner surface of the coating layer, the tensile strength is increased when bending and stretching, thereby increasing the service life of the reinforcing core. The compressive layer increases the compressive strength when subjected to pressure. The mesh support plate has a certain deformation capacity, which does not affect the bending of the reinforcing core and increases the compressive strength of the reinforcing core.

[0005] The present invention also provides a high-strength and tough reinforcing core as described above, comprising: an inner core, a composite layer disposed on the outer surface of the inner core, an outer layer fixedly connected to the outer surface of the composite layer, a compression-resistant layer fixedly connected to the outer surface of the outer layer, a covering layer disposed on the outer surface of the compression-resistant layer, and a tensile-resistant layer disposed on the inner surface of the covering layer.

[0006] According to the present invention, a high-strength and tough reinforcing core is provided, wherein the inner core is a composite inner core, specifically formed by winding multiple fiber cores.

[0007] According to the present invention, a high-strength and tough reinforcing core is provided, wherein the composite layer comprises: a waterproof layer and an insulating layer, wherein the waterproof layer is located on the outer surface of the insulating layer.

[0008] According to the present invention, a high-strength and tough reinforcing core is provided, wherein the outer layer is made of epoxy resin.

[0009] According to the present invention, a high-strength and tough reinforcing core is provided, wherein the compressive layer is specifically a mesh support plate.

[0010] According to the present invention, a high-strength and tough reinforcing core is provided, wherein the tensile layer is specifically a steel mesh, the steel mesh is located on the inner surface of the covering layer, and the two are fixedly connected.

[0011] A process for preparing a high-strength and tough reinforcing core includes the following steps:

[0012] S1. Inner core preparation: A single fiber core is passed through a winding machine to obtain the inner core;

[0013] S2. Composite layer preparation: Soft rubber is added at the feed point of the extruder, and a waterproof layer is generated on the outer surface of the inner core through the extruder. After the waterproof layer is prepared, the inner core is placed inside another extruder, hard rubber is added, and it is extruded again to generate an insulating layer on the outside of the waterproof layer.

[0014] S3, Outer layer preparation: multiple inner cores are glued together and placed inside an extruder. Epoxy resin raw materials are added to form an outer layer on the outer surface of the multiple inner cores.

[0015] S4. Install the anti-compression layer. The anti-compression layer is installed on the side surface of the outer layer by adhesive bonding and is evenly arranged around the center.

[0016] S5. Prepare the coating layer by attaching a steel mesh to the outer surface of the compression layer and connecting them by welding. Place the whole thing into the inside of the extruder, add rubber particles, and produce the coating layer on the outer surface of the steel mesh.

[0017] According to the high-strength and tough reinforcing core manufacturing process provided by the present invention, the steel mesh in S5 is the tensile layer.
