Wear-resistant halogen-free flame-retardant cable material

Abstract

The invention provides a wear-resistant halogen-free flame-retardant cable material. The wear-resistant halogen-free flame-retardant cable material is prepared by using the following raw materials, by weight, 30-40 parts of a PVC resin, 20-30 parts of a PVDF resin, 10-20 parts of a PEEK resin, 0.1-0.3 parts of calcium silicate, 2-10 parts of tributyl citrate, 0.2-0.5 parts of nanometer silicon carbide, 30-40 parts of magnesium hydroxide, 10-20 parts of antimonony oxide, 3-5 parts of zinc borate, 1-3 parts of zine stearate, 0.4-1.2 parts of a coupling agent, 5-10 parts of aluminum hypophosphite, 1-2 parts of calcium stearate, 1-2 parts of 4-methylguaiacol, 0.1-0.5 parts of an antioxidant 168, 0.1-1 part of a toner and 8-10 parts of a modification filler. Wear resistant resins and surface wear resisting agents are added, so good mechanical properties of the wear-resistant halogen-free flame-retardant cable material are maintained, and the wear resistance of the cable material is greatly improved.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a wear-resistant halogen-free flame-retardant cable material 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 to ac...

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.
