Cable material for outdoor charging piles and preparation method thereof

Abstract

The invention discloses a cable material for outdoor charging piles and a preparation method thereof. The material is made of the following raw materials in parts by weight: 20-25 parts of low-density polyethylene, 45-55 parts of mixed thermoplastic phenolic resin, TPU thermoplastic 15-20 parts of elastomer, 0.2-0.4 parts of nano-aluminum nitride powder, 1-2 parts of cross-linking agent, 1-2 parts of calcium stearate, 1-2 parts of stearic acid, UV-531 0.2- 0.4 parts, 3-5 parts of light stabilizer, 20-40 parts of compatibilizer, 7-10 parts of processing aid, 3-6 parts of antioxidant, 1-3 parts of anti-termite agent, appropriate amount of deionized water. The invention has excellent flame retardancy and non-flammability; when burning, the amount of smoke is very small, no toxic gas is produced, no corrosive gas is produced, and at the same time it has good low temperature resistance and ultraviolet resistance, and is very suitable for electric piles Use cable materials.

Description

technical field [0001] The invention relates to the technical field of cable production materials, in particular to a cable material for an outdoor charging pile and a preparation method thereof. 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...

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; charging pile cables are due to Its specific use environment leads to relatively stringent requirements for outer covering materials
