Flame-retardant cable material and preparing method thereof

Abstract

The invention discloses a flame-retardant cable material. The flame-retardant cable material is composed of, by weight, 2-3 parts of pentaerythritol, 6-10 parts of cresyl diphenyl phosphate, 2-4 parts of ammonium polyphosphate, 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 soapstone, 2-3 parts of sp80, 20-30 parts of lactide, 0.2-0.25 part of L-arginine, 3-7 parts of sasol wax, 1.6-2 parts of diisopropylethanolamine and 3-4 parts of quick lime. The cresyl diphenyl phosphate, the ammonium polyphosphate and the like which are added in the cable material have very good flame-retardant features, a better protection effect can be achieved, and the risk of fire disasters is reduced.

Description

Technical field [0001] The invention relates to the technical field of cables, in particular to a flame-retardant cable material and a preparation method thereof. Background technique [0002] Polylactic acid is an environmentally friendly material with good physical properties, biocompatibility and degradability. However, polylactic acid has poor heat resistance, toughness and crystallization properties, which restricts its application. Therefore, polylactic acid modification has always been a hot spot in polylactic acid research. The main modification methods include copolymerization modification, blending modification and blending. Hybrid filler technology, among which blending modification is more commonly used. In recent years, the preparation of polylactic acid / layered silicate nanocomposites to improve the comprehensive performance of polymer materials has become a research hotspot. Soapstone is unique to Xinjiang in China. The layered silicate with a trioctahedral struct...

[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.
