Preparation process of electric cable anti-formic acid protective sleeve

Abstract

The invention relates to the technical field of an electric cable and particularly relates to a preparation process of an electric cable anti-formic acid protective sleeve. A cable, an inner sheath, ashielding layer and an outer sheath are included, wherein the inner sheath covers a surface of the cable, an outer side of the inner sheath is extruded with the shielding layer, and the shielding layer is coated with the outer sheath. The preparation process is advantaged in that addition of stabilizer to the inner sheath can effectively improve anti-aging, anti-UV and anti-moisture resistance ofthe sheaths, nonivamide is a non-toxic, harmless and environmentally friendly substance, the substance has a strong spicy taste and is very irritating, which can effectively prevent mice and ants from biting, the shielding layer achieves the ant-repellent function by the odor, moreover, an ant-repellent drug layer includes mint and cactus, the cactus can have the slow release effect, the cable ismade to have the long-term odor repellency function, the outer sheath prevents the cable from being attacked by termites, normal operation of a power system is guaranteed, moreover, environmental pollution due to use of drugs acting on the termites is avoided, and the environment is further protected.

Description

technical field [0001] The invention relates to the field of fifth-generation mobile communication technology, in particular to a preparation process of a formic acid-resistant protective sleeve for a power cable. Background technique [0002] The application fields of cables are very wide, and the uses are also very large. They are mainly used in power systems, information transmission systems, mechanical equipment, instrumentation systems, etc. However, termite activities are frequent in nature, and damage to cables will cause serious harm to power and communication systems, and even cause major economic losses and casualties, especially in southern regions, mainly in Guangdong Province, where termite activities very frequently. [0003] In the past, cables were mainly protected against rodents and ants with drugs, but the disadvantage is that it pollutes the surrounding environment, and the rodents have strong adaptability. When they come into contact with the drugs, the...

However, termite activities are frequent in nature, and damage to cables will cause serious harm to power and communication systems, and even cause major economic losses and casualties, especially in southern regions, mainly in Guangdong Province, where termite activities very frequently

[0003] In the past, cables were mainly protected against rodents and ants with drugs, but the disadvantage is that it pollutes the surrounding environment, and the rodents have strong adaptability. When they come into contact with the drugs, they will gradually develop drug resistance, causing the cables to lose their ability to prevent rats and ants from gnawing. and formic acid corrosion function
