Embodiment Construction

[0013] Low-smoke halogen-free flame-retardant cable compound is made of raw materials with the following weight (kg):

[0014] Polyethylene 40, EVA20, magnesium hydroxide 45, nano-silicon carbide 5, nano-aluminum nitride powder 0.3, hydrotalcite 5, zinc molybdate 2, ethylene-octene copolymer grafted maleic anhydride 3, tricresyl phosphate 0.6 , calcium stearate 1, stearic acid 0.6, ultraviolet absorber UV-5310.3, modified filler 9,

[0015] Preparation:

[0016] Weigh each component raw material according to the formula ratio, stir the weighed component raw materials evenly in a high-speed mixer, and then banbury in a banbury mixer at a temperature range of 135-175°C, extrude with a twin-screw, and grind the surface eagerly Granulating, feeding by cyclone separator, screening by vibrating screen and then packaging, the finished cable material is obtained.

[0017] Wherein, the modified filler is prepared by the following method:

[0018] Calcinate the attapulgite at 550°C f...

Abstract

The invention provides a low-smoke halogen-free flame-retardant cable material. The low-smoke halogen-free flame-retardant cable material is prepared from the following raw materials in parts by weight: 30-40 parts of polyethylene, 20-30 parts of EVA (ethylene-vinyl acetate), 40-60 parts of magnesium hydroxide, 5-6 parts of nanometer silicon carbide, 0.2-0.4 part of nanometer nitriding aluminum powder, 4-6 parts of hydrotalcite, 2-3 parts of zinc molybdate, 2-4 parts of ethylene-octene copolymer grafted maleic anhydride, 0.1-1 part of tricresyl phosphate, 1-2 parts of calcium stearate, 0.5-1.0 part of stearic acid, 0.2-0.4 part of ultraviolet absorbent UV-531 and 8-10 parts of modified filler. The cable material provided by the invention has excellent flame resistance and incombustibility, generates little smoke during burning, does not generate poisonous gases and corrosive gases and meanwhile has good low temperature resistance, oil resistance and ultraviolet light resistance.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to low-smoke, halogen-free, flame-retardant cable materials. Background technique [0002] With the rapid development of the global economy and the enhancement of human awareness of environmental protection, the requirements for the quality and performance of wires and cables in various fields are getting higher and higher, and there are more and more fires caused by the aging of wires and cables. How to reduce the fire Low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or aluminum hydroxide to polyolefin substrates to achieve flame retardancy. However, the...
