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.
