Oil and low-temperature resistant low-smoke and halogen-free flame retardant cable material for boats, and its preparation method

Abstract

The invention provides an oil and low-temperature resistant low-smoke and halogen-free flame retardant cable material for boats. The cable material is prepared from the following raw materials, by weight, 20-30 parts of polyurethane, 60-80 parts of methyl vinyl silicone rubber, 8-10 parts of acrylonitrile-butadiene rubber, 8-10 parts of magnesium hydroxide, 0.5-1.0 part of butyl stearate, 1-3 parts of barium stearate, 8-12 parts of triglycol dioctate, 4-6 parts of copper oxide, 0.5-1.0 parts of molybdenum trioxide, 30-50 parts of fumed silica, 10-13 parts of modified argil, 0.5-1.0 part of an antioxidant H, 0.1-0.3 parts of an antioxidant AW, 0.5-1.5 parts of a promoter NOBS, 0.2-0.5 parts of a vulcanizing agent DCBP, 8-10 parts of triphenyl phosphate, 12-15 parts of antimony (III) oxide and 6-8 parts of zinc borate hydrate. The cable material has the advantages of excellent flame retardation, very less smoke in combustion, no generation of toxic gases or corrosive gases, good low temperature resistance, good oil resistance, and good abrasion resistance.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a marine oil-resistant, low-temperature, low-smoke, 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 magnesium h...

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.
