Radiation protection weather-resistant flame-retardant cable jacket material and preparation method thereof

Abstract

The invention discloses a radiation protection weather-resistant flame-retardant cable jacket material and a preparation method thereof. The radiation protection weather-resistant flame-retardant cable jacket material is prepared from the following raw materials in parts by weight: 60 to 70 parts of compound resin, 7 to 11 parts of radiation protection additives, 4 to 6 parts of rare-earth oxide,1 to 3 parts of titanium dioxide, 3 to 5 parts of heat-expansion graphite, 7 to 9 parts of compound flame-retardant agent, 6 to 8 parts of coupling agent, 4 to 8 parts of mixed fibers, 7 to 9 parts ofprocessing aids, 2 to 4 parts of heat stabilizer, 1 to 3 parts of zinc stearate, 2 to 4 parts of calcium carbonate, and 5 to 9 parts of filler. The radiation protection weather-resistant flame-retardant cable jacket material has good radiation protection performance, good mechanical characteristics, corrosion resistance, antioxidant performance and high temperature resistance, and good weather resistance and flame-retardant performance; and meanwhile, the preparation method is low-cost, the raw materials are easy to obtain, a process is distinctive, and good application prospect and high practical value are achieved.

Description

[0001] technical field [0002] The invention relates to the technical field of wire and cable manufacturing, in particular to a radiation-proof, weather-resistant, flame-retardant cable sheath material and a preparation method thereof. Background technique [0003] Large-scale military enterprises and enterprises shoulder the task of scientific research and modernization of national high-tech equipment, and most of the cables they need are high-temperature-resistant and light-weight fluorine-containing plastic products. In special fields such as military industry and nuclear power, due to the extremely harsh working environment, photovoltaic power plants need to use special cables with high temperature resistance and radiation protection. [0004] At the same time, the cable insulation material is an important part of the cable. It not only plays the role of insulation, but also plays the role of heat insulation and anti-corrosion. Once the insulation layer of the outer ...

Problems solved by technology

[0004] At the same time, the cable insulation material is an important part of the cable. It not only plays the role of insulation, but also plays the role of heat insulation and anti-corrosion. Once the insulation layer of the outer layer of the metal core is damaged, it will be greatly reduced. Cable performance

At present, cable insulation materials are difficult to meet the actual needs in terms of radiation protection

[0005] At present, the radiation protection material market is highly competitive, and traditional radiation protection materials have problems such as poor anti-interference performance, high production cost, narrow use range, high density, and easy corrosion, which will be limited in practical applications. In addition to radiation protection, it also needs to have the characteristics of easy processing, chemical corrosion resistance, high temperature resistance, fatigue resistance, and good chemical stability.
