The invention discloses a locomotive
cracking resistant cable material and a preparation method thereof. The locomotive
cracking resistant cable material is prepared from the following raw materials in parts by weight: 78-94 parts of LLDPE, 20-30 parts of PPTA, 22-28 parts of
basalt fibre, 15-20 parts of ATBC, 18-24 parts of a composite
flame retardant, 4-6 parts of
trimethylolpropane glyceryl cocoate, 3-5 parts of dodecanoic acid, 3-4 parts of
dibutyltin dilaurate, 2-3 parts of PDOP, 2-3 parts of
aluminium hydroxy distearate, 13-17 parts of
potassium titanate whisker, 10-15 parts of
cork powder, 2-3 parts of
resorcinol monobenzoate and 1-2 parts of
nickel dibutyldithiocarbamate. The cable material is excellent in
crack resistance, cannot easily crack under the long-term actions of low temperature and
impact force, and the like, and is high in
mechanical strength, better in electrical insulating property and
flame retardant property, organically integrates the electrical insulating property,
flame retardant property, mechanical performance and
cracking resistance, and is easy to manufacture, wide in material selecting range, lower in cost and good in use performance.
