Insulating material of cable for new energy automobile charging pile and preparation method of insulating material

Abstract

The invention discloses an insulating material of a cable for a new energy automobile charging pile and a preparation method of the insulating material. The generated poly (vinyl salicylate) molecular chain network can be alternately stacked with the hydrotalcite nanosheets, so that the impact resistance of the cable is improved, a compact protection layer can be formed on the surface of the cable, on one hand, optical fibers can be separated from oxygen, the oxidation problem is avoided, on the other hand, a salicylic acid structure contained in a molecular chain of the polyvinyl chloride has a relatively strong ultraviolet absorption effect, cable aging is prevented, the compatibility of the poly (vinyl salicylate) and the polyvinyl chloride is better, and a poly (vinyl salicylate) molecular chain network can also fix the filler, the stability of the filling material in the insulating material of the cable for the new energy automobile charging pile is improved, and the problem of cable breakage is prevented.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an insulating material for cables used in charging piles of new energy vehicles and a preparation method thereof. Background technique [0002] New energy vehicles, also known as alternative fuel vehicles, mainly refer to vehicles that use unconventional vehicle fuels as the power source, integrate advanced technologies in vehicle power control and drive, and form advanced technical principles with new technologies and new structures. The use of new energy vehicles can greatly reduce the use of petroleum energy and reduce exhaust emissions, which is of great significance to environmental protection. With the improvement of people's awareness of environmental protection, the development of new energy vehicles has become a global trend in the future. my country's new energy vehicles have now entered a stage of rapid development, and the use of new energy vehicles will enter the mark...

Problems solved by technology

Many existing fire-resistant cables often use halogen-containing flame retardants. Although these flame retardants can reduce the possibility of fire, they will release toxic substances, which not only pollute the environment, but also easily deposit in the human body, which is harmful to human health. make an impact

And the use of halogen-free flame retardants (such as magnesium hydroxide, aluminum hydroxide), although such flame retardant substances will not release toxic substances, but they are mostly sharp thorns or irregular crystals on the microcosm. When extruded and cooled, it is easy to cause cracks or even cracks in the cable shell, destroying the oxygen barrier layer and increasing safety hazards, especially when the cable is bent and placed, the cracks or cracks will be more serious

[0004] In addition, the charging piles of new energy vehicles are large in size and are generally installed outdoors. The charging pile cables are prone to aging and cracking under the sun's ultraviolet light for a long time, which affects the service life of the cables and increases safety hazards.
