Anticorrosion termite-insect-resistant power cable material and preparation method thereof

Abstract

The invention discloses an anticorrosion termite-insect-resistant power cable material. The power cable material is prepared by adopting the following raw materials in parts by weight: 94 to 96 parts of high-density polyethylene, 15 to 17 parts of decabromodiphenyl ether, 7 to 9 parts of antimonous oxide, 2 to 3 parts of metallocene polyethylene, 2 to 3 parts of nano magnesium hydroxide, 4 to 5 parts of cyclohexane, 0.2 to 0.3 part of gamma-aminopropyltriethoxysilane, 1.5 to 2 parts of antioxidant 1024, 1 to 2 parts of methylparaben, 4 to 6 parts of glass fibers, 0.2 to 0.3 part of permethrin, 2 to 3 parts of garlic powder, 10 to 12 parts of diatomite, 0.8 to 1 part of palmitoleic acid lauryl ester, 4 to 6 parts of clarified limewater, 3 to 4 parts of coumarone and 7 to 9 parts of natural rubber. Components such as permethrin, garlic powder, clarified limewater and the like are added and are synergistic, so that the power cable material has an insecticidal function, resists insects and termites, resists corrosion and ensures that a laid cable is prevented from being damaged by insects and termites. The component formula is a halogen-free flame-retardant anticorrosion formula and harmless to the environment, the mechanical performance is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a corrosion-resistant, insect-resistant and ant-resistant power cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose plastic with a wide range of uses. According to the amount of plasticizer added, it can be made into rigid, semi-rigid and soft products, and can also be modified by blending with other polymers. , made into a wide variety of products with different properties, the amount is very large, it is one of the world's top five general-purpose plastics. The global demand for PVC resin ranks the top three along with polyethylene and polypropylene, while its consumption in China has risen to the first place. Polyvinyl chloride itself is also an intrinsically flame-retardant material, with a high oxygen index and a good flame-retardant effect, but pure PVC is a rigid segment, which begins to de...

Problems solved by technology

[0004] At the same time, the common low-smoke halogen-free cables on the market do not have the function of preventing insect pests, and the cables with anti-insect corrosion are mostly PVC insulation and sheath.

Although polyvinyl chloride anti-termite cables have a certain anti-termite effect, the material has certain pollution to the environment and does not have high flame retardancy
