Problems solved by technology

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 disadvantages of poor wear resistance and impact resistance, resulting in short service life and unable to meet market demand. Therefore, it is urgent to change the formula of traditional automotive cable materials and develop a new automotive cable. materials to improve the wear resistance and impact resistance of automotive wires and cables

Embodiment Construction

[0018] A wear-resistant and impact-resistant cable material for automobiles, made of the following weight (kg) raw materials: nylon 6668, ultra-high molecular weight polyethylene 36, styrene-acrylonitrile-acrylate ternary block copolymer 18, polyethylene glycol Neopentyl glycol diacid 22, natural corundum 18, colloidal graphite powder 12, cobalt 2-ethylhexanoate 2.5, magnesium hypophosphite 4, Fischer-Tropsch wax 6, tetraoctyl pyromellitic acid 14, three (dodecyl) Mercaptan) antimony 3, composite flame retardant 18, antioxidant 10761.5, antioxidant 50571;

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

[0020] (1) Take colemanite, montmorillonite and magnesium molybdate in a ratio of 4:3:1 by mass, mix uniformly, pulverize, pass through an 80-mesh sieve, and then ball mill at 500r / min for 2h;

[0021] (2) Add water and stir the powder obtained by the above ball milling to prepare a suspension with a concentration of 40g / L, and then add a...

Abstract

The invention discloses a wear-resistant impact-resistant cable material for automobiles and a preparation method thereof. The cable material is prepared from the following raw materials, by weight, 56-74 parts of nylon 66, 32-44 parts of ultra-high molecular weight polyethylene, 14-22 parts of a styrene-acrylonitrile-acrylate ternary block copolymer, 18-24 parts of poly(neopentyl glycol adipate), 16-22 parts of natural emery, 10-15 parts of aquadag powder, 2-3 parts of cobalt 2-ethylhexanoate, 3-5 parts of magnesium hypophosphate, 4-7 parts of Fischer-tropsch wax, 12-16 parts of Tetraoctyl Pyromellitate, 3-4 parts of antimony tri(n-dodecanethiol), 15-20 parts of a composite flame retardant, 1-2 parts of an antioxidant 1076 and 1-2 parts of an antioxidant 5057. The prepared cable material has superior comprehensive physical properties, high mechanical strength and excellent abrasive resistance and impact resistance, is used to greatly prolong service life of a cable, and meets use requirements of automobile wires and cables.

Description

technical field [0001] The invention relates to a cable material, in particular to a wear-resistant and impact-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 disadvantages of poor wear resistance and impact resistance, resulting in short service life and unable to meet market demand. Therefore, it is urgent to change the...
