Problems solved by technology

[0002] Among the currently used communication cables, the RG-58 coaxial cable is a commonly used one. Its insulating material is generally foamed polyethylene (FMPE material for short), and it has some shortcomings in use, such as: In terms of temperature resistance, it can generally only reach 80°C; in terms of signal transmission performance, it is easy to attenuate and its mechanical properties are not ideal. Therefore, it is very necessary to improve the product performance of high temperature resistant communication cables.

Embodiment Construction

[0014] Below in conjunction with embodiment and accompanying drawing, the present invention is further narrated: present embodiment is the process of producing RG-58 coaxial cable product of an example, and this product is to implement a model in the wire and cable standard MIL-C-13, and all in the standard The material used is polyethylene (referred to as PE) or foamed polyethylene (referred to as FMPE). Cross-linked foamed polyethylene (referred to as XL-FMPE) material, according to the structure of Figure 2 to produce high temperature resistant coaxial cables, the specific production process is as follows:

[0015] 1. Mixing: The polyethylene with the grade of DGDA6944 and the crosslinking agent with the grade of TA001 are mixed according to the ratio of 98:2, and mixed on the mixer. The mixing temperature is 100°C, the time is 6 minutes, and the rotation speed is 100RPM.

[0016] 2. Granulation: The above homogeneous mixture is directly put into the granulator for extrusio...

Abstract

Technical scheme of the invention is as following: cross linking foamed polyethylene as base material, turning foamed polyethylene over to out, irradiating the turned out insulated core wire under proper dosage through electron gun so as to generate cross linking. Detailed procedures are: selecting PC base material and cross linking agent, extrusion granulating through mixing roll, foaming and turning it over out, irradiation cross linking, preparing shielding layer, and wrapping outer covering. Comparing with current communication cable made from expanded polyethylene with thermal endurance class 80 deg.C , the invention uses cross-linked foamed polyethylene as insulating material with thermal endurance class 105 deg.C, providing features of high withstand voltage, weatherability, mechanical properties, and fine transmission performance.

Description

technical field [0001] The invention relates to a production method of a communication cable and its products, in particular to a high-temperature-resistant coaxial communication cable whose insulating material is cross-linked foamed polyethylene. Background technique [0002] Among the currently used communication cables, the RG-58 coaxial cable is a commonly used one. Its insulating material is generally foamed polyethylene (FMPE material for short), and it has some shortcomings in use, such as: In terms of temperature resistance, it can generally only reach 80°C; in terms of signal transmission performance, it is easy to attenuate and mechanical properties are not ideal. Therefore, it is very necessary to improve the product performance of high temperature resistant communication cables. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention proposes a new technical solution: first find a cross-li...
