Abstract

The invention discloses a low-smoke halogen-free flame-retardant crack-resistant cable material and a preparation method thereof. The low-smoke halogen-free flame-retardant crack-resistant cable material is prepared from the following raw materials in parts by weight: 65-75 parts of high-density polyethylene, 30-40 parts of ethylene-vinyl acetate copolymer, 7-9 parts of phenyl alkyl sulfonate, 4-6 parts of diethanolamine borate, 3-5 parts of magnesium dimethyl acrylate, 8-10 parts of magnesium hydroxide, 40-50 parts of tolyl diphenyl phosphate, 4-7 parts of 3-aminopropyltriethoxy silane, 7-9 parts of trimethylsilane-base cage-type polysilsesquioxane, 6-8 parts of organic antimony stabilizer, 5-7 parts of p-phenylenediamine, 30-40 parts of nano colemanite, 8-10 parts of Ome mineral fiber, 8-10 parts of hexachlorocyclotriphosphonitrile, 6-8 parts of carnauba wax, 10-12 parts of polyarylether ether nitrile, 7-8 parts of zirconium carbide, 5-8 parts of fibrous plaster, 4-6 parts of calcium hypophosphite and 8-12 parts of high-wear-resistance carbon black. The cable material has the advantages of favorable flame-retardant effect, less fuming and favorable cracking resistance.

Description

technical field [0001] The invention relates to a cable material, in particular to a low-smoke, halogen-free, flame-retardant, crack-resistant cable material and a preparation method thereof. Background technique [0002] In recent years, with the vigorous development of my country's 4G network, urban rail transit, railways, building construction and other projects, the demand for radio frequency cables such as mobile communication radio frequency cables, leaky cables, and railway signal cables has risen sharply, prompting low-smoke and halogen-free resistance The use of fuel cables is growing rapidly. The research and production of low-smoke, halogen-free and flame-retardant cable materials in my country has a history of more than ten years. Although with the continuous improvement of the material technology, the extrusion process of low-smoke, halogen-free, and flame-retardant cable The speed and speed have been greatly improved, but the problem of easy cracking of low-smok...
