Embodiment Construction

[0016] A flame-retardant polypropylene cable material, which is made from the following raw materials in parts by weight (kg): chlorinated polyethylene 100, isotactic polypropylene 20, magnesium stearate 2, aluminum hydroxide 15, magnesium hydroxide 4. Dibutyl maleate 2, calcium oxide 1.9, zinc oxide 1, zinc stearate 0.6, phthalic acid polyester 0.3, epoxy soybean oil 2, barium sulfate 2, modified dolomite powder 70, Methyltrimethoxysilane 1.72, antioxidant DLTP 1.8;

[0017] Modified dolomite powder is made from the following raw materials in parts by weight:

[0018] Dolomite 25, heavy calcium carbonate 2, steel slag 2, antioxidant 2246 0.5, zinc oxide 2, chlorinated paraffin 1, zinc borate 6, toluene diphenyl phosphate 3.5, aluminum hydroxide 10;

[0019] The preparation method is to mix dolomite, heavy calcium carbonate, and steel slag, and then calcinate at 830°C for 3.5 hours, then take it out, add an appropriate amount of water to grind it together with aluminum hyd...

Abstract

The invention discloses a flame-retardant polypropylene cable material. The flame-retardant polypropylene cable material is prepared from 100-110 weight parts of chlorinated polyethylene, 10-20 weight parts of isotactic polypropylene, 1-2 weight parts of magnesium stearate, 10-15 weight parts of aluminum hydroxide, 2-4 weight parts of magnesium hydroxide, 1-2 weight parts of dibutyl maleate, 1.5-3 weight parts of calcium oxide, 0.8-1 weight part of zinc oxide, 0.4-0.6 weight parts of zinc stearate, 0.3-0.5 weight parts of phthalic polyester, 1-2 weight parts of epoxidized soybean oil, 1-2 weight parts of barium sulfate, 60-70 weight parts of modified dolomite powder, 1-2 weight parts of methyltrimethoxysilane and 1.4-3 weight parts of an anti-oxidant DLTP.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a flame-retardant polypropylene cable material. Background technique [0002] Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of only 0.90--"0.91g / m3. It is one of the lightest types of all plastics. It is particularly stable to water. The water absorption rate in water is only 0.01%, and the molecular weight is about 80,000-150,000. The formability is good, but due to the large shrinkage rate (1%~2.5%), thick-walled products are easy to sag, and some dimensional accuracy is high Parts, it is difficult to meet the requirements, the product surface gloss is good, easy to color. [0003] Special resins for wire and cable include cable insulation materials and cable sheath materials, and the raw materials used are mainly polyethylene and polyvinyl chloride. [0004] Polyethylene is a crystalline thermoplastic resin. Their chem...
