Abstract

The invention provides a congelation-resistant cable insulating coating. The congelation-resistant cable insulating coating consists of modified epoxy resin, an aluminium nitride mixture, a coupling agent, a curing agent and a curing accelerator, wherein the epoxy resin is modified by a highly-fluorinated special organic silicon material (hydroxyl-terminated polymethyl 17-fluorine decyl siloxane), and the low-surface energy property of the fluorine element is utilized, so that the hydrophilic property of the epoxy material is changed, and the modified epoxy base material with high hydrophobicity is obtained; and the modification is performed by inorganic rigid grain aluminium nitride filler with multiple grain diameters, and the coupling agent is utilized, so that the binding property of the aluminium nitride grain-the coupling agent-the resin interface is stable, the toughening effect is good, and the heat conduction ability of the modified epoxy resin is greatly improved by the high heat conductivity of the aluminium nitride grains after filling.

Description

technical field [0001] The invention relates to a cable insulating coating, in particular to an anti-freezing cable insulating coating, which belongs to the technical field of cable materials. Background technique [0002] With the rapid development of my country's economy, energy demand will continue to increase, which has higher requirements for my country's power transmission and distribution industry. For power transmission, especially for long-distance transmission, cables are still the main transmission mode. Therefore, the stability of the cable system will directly affect the transmission capacity and transmission efficiency. Due to long-term exposure to the natural environment, transmission cables have high requirements for their insulation and weather stability. Especially in areas with harsh natural conditions, the weather resistance of cables is particularly important. The most prominent performance is that the safe operation of power and communication network...
