Embodiment Construction

[0018] A hydrolysis-resistant cable material for automobiles, made of the following raw materials by weight (kg): EPDM rubber 55, tetrapropylene fluorine rubber 30, rectorite powder 12, C5 hydrogenated petroleum resin 8, tert-butyl peroxide Hydrogen 2.5, basic lead carbonate 2, poly-p-dinitrosobenzene 4, dibutyl sebacate 6, magnesium oxide 2.5, zinc stearate 1.5, disproportionated rosin 4, N-ethyl-p-toluenesulfonamide 3.5, Composite flame retardant 14, spherical silica powder 8, accelerator PPD1.5, accelerator ZBPD1, anti-aging agent 22461;

[0019] The preparation method of described composite flame retardant is as follows:

[0020] (1) Take colemanite, montmorillonite and magnesium molybdate in a mass ratio of 5:2:1, mix them uniformly, pulverize, pass through a 100-mesh sieve, and then ball mill at 550r / min for 1.5h;

[0021] (2) Add water and stir the powder obtained by the above ball milling to prepare a suspension with a concentration of 45g / L, and then add a certain vo...

Abstract

The invention discloses a hydrolysis-resistant cable material for an automobile and a preparation method of the hydrolysis-resistant cable material. The hydrolysis-resistant cable material is prepared from the following raw materials, by weight part: 45-60 of ethylene propylene diene monomer rubber, 22-34 of tetrafluoroethylene-propylene rubber, 9-14 of rectorite powder, 5-10 of C5 hydrogenated petroleum resin, 2-3 of tert-butyl-hydroperoxide, 1.5-2.5 of basic lead carbonate, 3-5 of polyparadinitrosobenzene, 4-8 of dibutyl sebacate, 2-3 of magnesium oxide, 1-2 of zinc stearate, 3-6 of disproportionated rosin, 2.5-4.5 of N-ethyl-p-toluenesulfonamide, 12-17 of a composite flame retardant agent, 5-10 of spherical silicon powder, 1-2 of an accelerant PPD, 1-2 of an accelerant ZBPD, and 1-2 of an antioxidant 2246. The prepared cable material has excellent hydrolysis resistance, so that the electric wires and cables of the automobile can be effectively prevented against hydrolysis. The cable material can maintain excellent properties after continuously used in high pressure and high temperature, and has good electrical insulation property, mechanical strength, corrosion resistance, abrasive resistance, and thermal resistance.

Description

technical field [0001] The invention relates to a cable material, in particular to a hydrolysis-resistant cable material for automobiles and a preparation method thereof. Background technique [0002] With the rapid development of the economy, wires and cables have been widely used in the automotive industry. In recent years, automobile electrical fire accidents 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. At the same time, the automotive cable materials currently on the market generally have the disadvantage of poor hydrolysis resistance, and are prone to performance aging in water for a long time. Therefore, it is urgent to change the formula of traditional automotive ca...
