Embodiment Construction

[0010] A anti-mold polyethylene sheath material for cables, made of the following raw materials in weight (kg): linear low-density polyethylene 80, chlorosulfonated polyethylene 20, poly-4-methyl-1-pentene 10, Carbon black N66025, turpentine 6, dioctyl terephthalate 8, anilinomethyltriethoxysilane 1.5, methyl p-hydroxybenzoate 4, decabromodiphenyl ether 10, zinc borate 8, aluminum hydroxide 12, Brucite powder 6, tris(2-chloropropyl) phosphate 8, light magnesium oxide 3, tributyl tin chloride 1.5, barium hardate 2, calcium hydroxide 4, oxidized polyethylene wax 3, quartz powder 6. Nano silver 4, composite filler 5;

[0011] The preparation method of the composite filler is as follows: a. Take bentonite, barite, and monazite in a weight ratio of 5:4:3, then add 2% coal powder and 1% activated carbon by weight of bentonite, and mix them uniformly at 560 ° C. Calcined for 3 hours, cooled to room temperature, crushed to a particle size below 15 μm, then added water to beat to make...

Abstract

The invention discloses a moldproof polyethylene sheath material for cables and a preparation method thereof. The moldproof polyethylene sheath material for cables is prepared from the following raw materials in parts by weight: 80-90 parts of linear low density polyethylene, 15-20 parts of chlorosulfonated polyethylene, 10-15 parts of poly(4-methyl-1-pentene), 20-30 parts of carbon black N660, 4-8 parts of turpentine, 5-10 parts of dioctyl terephthalate, 1-2 parts of anilinomethyl triethoxy silane, 3-5 parts of methyl p-hydroxybenzoate, 8-12 parts of decabromodiphenyl oxide, 5-10 parts of zinc borate, 10-15 parts of aluminum hydroxide, 4-8 parts of brucite powder, 5-10 parts of tri(2-chloropropyl)phosphate, 2-4 parts of light magnesium oxide, 1-2 parts of tributyltin chloride, 2-3 parts of barium stearate, 3-6 parts of calcium hydroxide, 3-4 parts of oxidized polyethylene wax, 5-8 parts of quartz powder, 3-5 parts of nano silver and 4-6 parts of composite filler. On the premise that the excellent moldproof function of the sheath material is ensured, the sheath material can effectively inhibit Aspergillus niger, Aspergillus terreus and other molds from growth and reproduction, so that the cable is free from mold invasion, and the service life of the sheath is prolonged.

Description

technical field [0001] The invention relates to a cable sheath material and a preparation method thereof, in particular to an anti-mold polyethylene sheath material for cables and a preparation method thereof. Background technique [0002] The cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and isolating the copper wire from water, air and other media to avoid leakage. In recent years, with the improvement of people's living standards and people's awareness of environmental protection and health, the cable industry has also expanded the demand for anti-mold sheath materials. However, most of the existing flame-retardant polyethylene sheath materials do not have The anti-mold function, or the anti-mold function is not obvious, and cannot meet the needs of users. Contents of the invention [0003] The object of the present invention is to provide an anti-mold polyethy...
