Soft environment-friendly polyolefin cable material

Abstract

The invention provides a soft environment-friendly polyolefin cable material prepared from the following raw materials in parts by weight: 20-30 parts of a PE resin powder, 40-50 parts of EVA, 10-15 parts of a POE elastomer, 4-5 parts of ACR resin, 20-30 parts of magnesium hydroxide, 20-30 parts of aluminum hydroxide, 10-20 parts of a talcum powder, 4-5 parts of molybdenum trioxide, 2-3 parts of iron oxide, 8-10 parts of tributyl citrate, 1-2 parts of an antioxidant 1010, 20-30 parts of triethyl O-acetylcitrate, 1-2 parts of pentaerythritol, 1-2 parts of melamine cyanurate, 1-2 parts of polytetrafluoroethylene, 1-2 parts of stearic acid, 1-2 parts of paraffin, and 8-10 parts of a modified filler. The cable material has high softness degree and excellent mechanical properties, and can meet use in communication cables, weak electric cables and other industries having higher demands on the cable softness degree.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a soft and environment-friendly polyolefin 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 magnesium hydroxide to polyolefin substrates to achieve flame retardancy. However, t...

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 magnesium 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.
