Embodiment Construction

[0015] A flame-retardant polypropylene cable material for urban rail transit, made of the following raw materials (kg): polypropylene 53, polyetherimide 44, brominated polystyrene 25, ultrafine molybdenum powder 16, guaiac Resin 12, epoxy fatty acid methyl ester 11, diethylene glycol dibenzoate 9, sasol wax 4.5, isopropyl myristate 3, stannous stearate 1.5, tris(2,3-dibromopropyl ) Isocyanurate 6, activated calcium carbonate 17, barium stannate 8, dibenzoylmethane 2.5, composite flame retardant 17, antioxidant 11351.5, antioxidant 3301;

[0016] The preparation method of described composite flame retardant is as follows:

[0017] (1) Take palygorskite, attapulgite and barium metaborate according to the ratio of mass ratio 7:4:3, mix uniformly, pulverize, pass through a 150 mesh sieve, and then ball mill at 800r / min for 0.5h;

[0018] (2) Add water and stir the powder obtained by the above ball milling to prepare a suspension with a concentration of 60g / L, and then add a certa...

Abstract

The invention discloses a flame resistant polypropylene cable material for urban rail transport and a preparation method thereof. The flame resistant polypropylene cable material is prepared from the following raw materials, by weight, 42-58 parts of polypropylene, 34-49 parts of polyetherimide, 18-27 parts of brominated polystyrene, 13-19 parts of ultrafine molybdenum powder, 8-14 parts of guaiac resin, 10-15 parts of epoxidized fatty acid methyl esters, 6-12 parts of diethylene glycol dibenzoate, 3-6 parts of Sasol wax, 2-4 parts of isopropyl myristate, 1-2 parts of stannous stearate, 4-8 parts of tri(2,3-dibromopropyl)tricarbimide ester, 15-20 parts of activated calcium carbonate, 5-10 parts of barium stannate, 2-3 parts of dibenzoyl methane, 15-20 parts of a composite flame retardant, 1-2 parts of an antioxidant 1135 and 1-2 parts of an antioxidant 330. The prepared cable material has good flame retardant efficiency and low smoke density, will not generate heavy smoke and harmful, toxic and corrosive gas when burned, is safe and environmentally-friendly, and has characteristics such as excellent physical and mechanical properties, electrical insulation property, fatigue resistance, heat resistance, weather fastness and the like.

Description

technical field [0001] The invention relates to a cable material, in particular to a flame-retardant polypropylene cable material for urban rail transit and a preparation method thereof. Background technique [0002] With the rapid development of the economy, wires and cables have been widely used in the urban rail transit industry. In recent years, electrical fire accidents in urban rail transit have occurred frequently, and the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. When the cable burns, it releases a large amount of smoke and toxic and corrosive gas, which seriously hinders people's safe evacuation and fire fighting work, causing serious loss of life and property. Therefore, it is urgent to change the formula of traditional urban rail transit cable materials and develop a new urban rail transit cable material to improve the flame retardancy of urban rail transit wires and cables.
