Novel low-smoke zero halogen flame-retardant cable material

Abstract

The invention discloses a novel low-smoke zero halogen flame-retardant cable material which comprises the following raw materials in parts by weight: 30-50 parts of EVA resin, 30-60 parts of silane coupling agent modified magnesium hydrate fire retardant, 5-6 parts of nanometer silicon carbide, 0.2-0.4 parts of nanometer aluminum nitride powder, 1-2 parts of cross-linking agents, 1-2 parts of calcium stearate, 0.5-1.0 part of stearic acid, 0.2-0.4 part of ultraviolet light absorber UV-531, 8-15 parts of smoke suppression agents, 20-40 parts of compatilizer, 1-4 parts of antioxygen, 7-10 parts of processing agents, 3-6 parts of antioxygen and 1-3 parts of termite resistances. The novel low-smoke zero halogen flame-retardant cable material has excellent fire resistance and non-delay flammability; during a burning process, the smoke volume is less, no toxic gas is generated and no corrosive gas is generated; the low temperature resistance and the uvioresistant property are excellent.

Description

technical field [0001] The invention relates to the technical field of cable production materials, in particular to a novel low-smoke halogen-free flame-retardant cable material. 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...

Problems solved by technology

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 addition of a large amount of inorganic materials affects the physical and mechanical properties and processing performance of the cable material. Its softness, poor weather resistance, oil resistance, and low temperature resistance at room temperature are not very good.
