Problems solved by technology

Different operating environments have different requirements on the structure, material and performance of the Ethernet outer sheath, such as field equipment, field operations, etc., which have high requirements on the wear resistance of the Ethernet outer sheath, in order to prevent Long-term field operations lead to wear and tear of the outer sheath of the Ethernet, which eventually leads to unstable signal transmission
[0003] However, the existing Ethernet anti-wear protection layer not only needs to have good wear resistance, but also meet safety performance such as flame retardancy. However, when conventional flame retardants are added, the compatibility of materials often occurs. Embrittlement and wear-resistant conditions

Abstract

The invention relates to an Ethernet line, and discloses an Ethernet anti-wear protection layer and a preparation method. The method comprises the following steps that (1) polyvinylidene fluoride, a carbon nanotube and silicon dioxide are subjected to primary mixing in a high-speed mixer; (2) a composite flame retardant is added into the high-speed mixer to be subjected to secondary mixing with afirst mixture; (3) a compatible toughening agent and a second mixture are continuously mixed, a temperature of the material is made to increase to 95-115 DEG C, and discharging and cooling are conducted; and (4) a cooled mixed material is fed into a twin-screw extruder for melt co-extrusion. The Ethernet anti-wear protection layer not only has good wear resistance, but also has good flame retarding performance.

Description

technical field [0001] The invention relates to an Ethernet cable, in particular to an Ethernet anti-wear protection layer. Background technique [0002] Industrial Ethernet technology is derived from Ethernet technology, but there are great differences and differences between it and ordinary Ethernet technology. Industrial Ethernet technology itself has been adjusted in terms of adaptability, and at the same time combined with the needs of industrial production safety and stability, corresponding control application functions have been added, and corresponding solutions that meet the needs of specific industrial application sites have been proposed.
