Outdoor sun protection cable material and preparation method thereof

Abstract

The invention discloses an outdoor sun protection cable material. The outdoor sun protection cable material is composed of, by weight, 10-18 parts of 2-ethylhexyl epoxystearate, 570-600 parts of polyvinyl chloride, 0.06-0.1 part of sodium iodide, 70-100 parts of soapstone, 2-3 parts of sp80, 2-4 parts of sodium citrate, 20-30 parts of lactide, 0.2-0.25 part of L-arginine, 1-2 parts of molybdenum boride, 0.8-2 parts of magnesium fluoride, 2.1-3 parts of 2-hydroxy-4-n-octyloxybenzophenone, 2-4 parts of inositol hexaphosphoric acid, 17-20 parts of fulvic acid, 12-15 parts of sepiolite powder and 40-50 parts of isopropanol. The cable sheath material is particularly suitable for the outdoor working environment, good in sun protection performance, high in high-temperature resistance, not prone to be stripped and good in ageing resistance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an outdoor sun-resistant cable material and a preparation method thereof. Background technique [0002] Polylactic acid is an environmentally friendly material with good physical properties, biocompatibility and degradability.

[0002] Polylactic acid is an environmentally friendly material with good physical properties, biocompatibility and degradability. However, the heat resistance, toughness and crystallization properties of polylactic acid are poor, which restricts its application. Therefore, the modification of polylactic acid has always been a hot spot in the research of polylactic acid. Miscellaneous filler technology, among which the use of blending modification is more commonly used. In recent years, it has become a research hotspot to improve the comprehensive performance of polymer materials by preparing polylactic acid / layered silicate nanocomposites. Saponite is unique in Xinjiang, my country. The phyllosilicate with three-octahedral structure has attracted much attention because of its excellent surface properties, expansion properties, and cation exchange capacity. In order to improve the interfacial compatibility between saponite and polymers, organic modification of saponite is very important. , due to the increase of the interlayer distance of saponite after organic modification, it is beneficial for the polymer to obtain an intercalation or exfoliation structure, and realize the nano-modification of the polymer material, thereby improving the performance of the polymer. Currently, the most studied saponite Modifiers are mainly alkyl quaternary ammonium salts, while studies on saponite modified by fulvic acid quaternary ammonium salts are rarely reported.
