Problems solved by technology

[0002] At present, mine cables have formed a considerable scale after rapid development, and the production capacity has greatly exceeded the forecasted demand value for this year. Most mine cables are used in harsh underground environments. Most mines are high-temperature, flammable and corrosive. Aluminum hydroxide Because of its characteristics of low smoke or no smoke, permanent flame retardant, non-toxic, no leakage, no migration, low cost, and no pollution to the environment, it conforms to the general trend of flame retardants developing towards environmental protection. It is used in mining cable sheaths The application of aluminum hydroxide is more and more extensive, but when aluminum hydroxide is used, due to the surface chara...

The sheath material is prepared from the following raw materials in parts by weight: 40-50 parts of polyvinyl chloride resin, 30-40 parts of EVA (ethylene-vinyl acetate copolymer) resin, 1-2 parts of triethanolamine, 10-15 parts of modified aluminium hydroxide, 20-30 parts of magnesium hydroxide, 1-2 parts of zinc oxide, 0.5-0.8 part of accelerator TAC, 0.5-1 part of accelerator HVA-2, 1-1.5 parts of triallyl isocyanurate, 0.4-0.6 part of di-tert-butyl peroxide, 1-1.6 parts of light magnesium oxide, 1-3 parts of anti-aging agent A, 0.5-1.5 parts of anti-aging agent 4010NA, 20-30 parts of carbon black N990, 12-16 parts of diatomite and 30-45 parts of calcined clay. The sheath material has good processability, good mechanical properties and excellent flame retardance.

Description

technical field [0001] The invention relates to the technical field of mine cables, in particular to a high-performance mine modified cable sheath material. Background technique [0002] At present, mine cables have formed a considerable scale after rapid development, and the production capacity has greatly exceeded the forecasted demand value for this year. Most mine cables are used in harsh underground environments. Most mines are high-temperature, flammable and corrosive. Aluminum hydroxide Because of its characteristics of low smoke or no smoke, permanent flame retardant, non-toxic, no leakage, no migration, low cost, and no pollution to the environment, it conforms to the general trend of flame retardants developing towards environmental protection. It is used in mining cable sheaths The application of aluminum hydroxide is more and more extensive, but when aluminum hydroxide is used, due to the surface characteristics of the aluminum hydroxide filler, which is hydrophi...
