Low-smoke stable cable material and preparing method thereof

Abstract

The invention discloses a low-smoke stable cable material. The material comprises, by weight, 3-4 parts of methyl tin mercaptide, 1-2 parts of solydimethyl siloxane, 4-7 parts of polyethyleneimine, 6-9 parts of ethylparaben, 570-600 parts of polyvinyl chloride, 17-20 parts of fulvic acid, 3-5 parts of calcium hydrophosphate, 0.06-0.1 part of sodium iodide, 80-100 parts of isopropanol, 70-100 parts of soapstone, 2-3 parts of sp80, 0.8-2 parts of epoxy chloropropane, 20-30 parts of lactide, 0.2-0.25 part of L-arginine, 1-2 parts of sodium mercaptobenzothiazole, 3-4 parts of lanolin, 1-2 parts of polyoxyethylene castor oil and 3-5 parts of chlorinated paraffin. According to the cable sheath material, the polyvinyl chloride modified by the methyl tin mercaptide is adopted so that the stability of a finished product can be well improved. The finished material is good in high and low temperature resistance, high in flame redardance and high in safety, and can effectively reduce fire risks.

[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.
