Problems solved by technology

Typical non-metallic materials include nylon and imitation nylon. Nylon has high hardness, good toughness and surface smoothness, and has a good effect of preventing rodents, insects and ants. However, its manufacturing process is troublesome and its manufacturing cost is relatively high. There are fewer applications in industrial use
The chemical control method is to add a certain amount of repellent or repellant to the material to achieve the effect of preventing rodents, insects and ants. However, many repellents are prohibited due to toxicity or serious environmental pollution.
Among the existing wire and cable products, wires and cables are prone to aging and deformation or even rupture under high temperature environment, which will also cause leakage and other incidents

Description

technical field [0001] The invention belongs to the field of cable material preparation, and in particular relates to a method for preparing an insect-proof, high-temperature-resistant, flame-retardant cable. Background technique [0002] At present, wire and cable products have been widely used in electric power, construction, communication, manufacturing and other industries. However, because mice and insects need to grind their teeth, wires and cables are usually bitten by mice and insects; Accidents happen. Existing methods for preventing insects and termites include physical control and chemical control. Among them, physical control mainly uses the hardness, toughness and surface smoothness of the material to achieve the effect of preventing rodents, insects and ants. Typical non-metallic materials include nylon and imitation nylon. Nylon has high hardness, good toughness and surface smoothness, and has a good effect of preventing rodents, insects and ants. However, ...
