Example Embodiment

[0021] An anti-corrosion and anti-aging cable material, which is composed of the following parts by weight:

[0022] Polyvinyl alcohol 3, sodium diacetate 1, calcium propionate 3, 2,6 di-tert-butyl p-cresol 2, benzotriazole 10, polyvinyl chloride 570, yellow humic acid 17, sodium iodide 0.06, iso Propanol 40, soapstone 70, sp802, lactide 20, L arginine 0.2, and butyl benzyl phthalate 14.

[0023] A method for preparing the anti-corrosion and anti-aging cable material includes the following steps:

[0024] (1) Adding yellow humic acid to 2 times 25% ammonia water, keeping the temperature at 150°C for 50 minutes to obtain yellow humic acid amide;

[0025] (2) Mix yellow humic acid amide, 2,6 di-tert-butyl-p-cresol and sodium iodide, add to isopropanol, react at 70°C for 20 hours, distill under reduced pressure to remove isopropanol, and freeze Dry to obtain yellow humic acid quaternary ammonium salt;

[0026] (3) Add calcium propionate to 6 times water, stir evenly, add sodium diacetate...

Abstract

The invention discloses an anti-corrosion and anti-aging cable material. The cable material comprises, by weight, 3-6 parts of polyvinyl alcohol, 1-2 parts of sodium diacetate, 3-4 parts of calcium propionate, 2-4 parts of 2,6-ditertbutyl-4 methylphenol, 10-14 parts of benzotriazole, 570-600 parts of polyvinyl chloride, 17-20 parts of fulvic acid, 0.06-0.1 part of sodium iodide, 40-50 parts of isopropanol, 70-100 parts of saponite, 2-3 parts of sp802, 20-30 parts of lactide, 0.2-0.25 part of L-arginine and 14-20 parts of butyl benzyl phthalate. The added sodium diacetate and calcium propionate of the cable material have excellent anti-microbial and anti-corrosion performance, and therefore the cable material is applicable to humid and dark working environments and other poor working environments and is long in service life.
