Problems solved by technology

The sheath materials used in the existing modified cable sheaths can only improve the cold resistance performance, or can only improve the flexibility performance alone, and cannot meet the two needs of cold protection and flexibility at the same time.

Embodiment 1

[0040] 1. Rubber sheath flexible cable sheath material for wind power generation, based on 100kg of low-temperature resistant chloroprene rubber, anti-aging agent (ODA 6kg), softener (DOP 15kg), reinforcing filler (active reinforcing agent 50kg), coupling agent (SI-692kg) and vulcanizing agent (zinc oxide).

[0041] 2. The preparation method is:

[0042] 1) In order to ensure uniform mixing, a multi-stage mixing process is adopted. The first stage internal mixer uses low-speed mixing, the mixing temperature does not exceed 100°C, and the mixing time is about 12 to 14 minutes.

[0043] 2) The vulcanizing agent is added in the second stage, the amount of vulcanizing agent added is 5.5kg, the internal mixer is mixed at a low speed, the mixing temperature does not exceed 90°C, and the mixing time is about 2.5 to 4 minutes.

[0044] 3) In order to ensure the smooth surface of the extrusion sheath, the above compounded materials must be parked for 24 hours before extrusion, and the...

Abstract

The invention relates to a cable shield material and a preparation method, in particular to a rubber jacketed flexible cable shield material for wind generation and a preparation method thereof. The rubber jacketed flexible cable shield material for wind generation contains chloroprene rubber, anti-aging agent, a softening agent, a reinforced filler, a coupling agent and a vulcanizator. The rubber jacketed flexible cable shield material for wind generation meets the requirement of resistance on the low temperature of 40 DEG C below zero and 2000-time twisting of H07RN-F and H07BRN4-F type wind energy cables, has the good properties of inflaming resistance, weather resistance, oil resistance, ozone resistance, chemical corrosion resistance, wearing resistance, shock resistance, water prevention, ultraviolet prevention and the like, and ensures that cables can be normally and safely used at low temperature in the open air.

Description

technical field [0001] The invention relates to a cable sheathing material and a preparation method thereof, in particular to a rubber-sheathed flexible cable sheathing material for wind power generation and a preparation method thereof. Background technique [0002] Due to its energy-saving and environmental protection properties, wind energy resources are increasingly used in many fields including wind power generation. However, there are still some defects in the cables used for wind power generation at present. For example, the currently widely used wind energy cables are polymer crystalline materials with plastic properties such as polyethylene or polyurethane, which leads to aging and brittleness due to the low temperature environment in nature when the wind energy cables are continuously used outdoors , cracking and other problems, and at the same time, after being corroded under acid and alkali conditions, it is easy to cause a significant decrease in physical and m...
