Low temperature resistant oil-proof type halogen-free flame retardant cable material

Abstract

The invention relates to a low temperature resistant oil-proof type halogen-free flame retardant cable material, comprising the following raw materials in parts by weight: 100 parts of ethylene-vinyl acetate, 10-15 parts of vinyl resin with polar groups, 29-40 parts of polyether polyurethane resin, 140-170 parts of aluminum hydrate, 15-55 parts of magnesium hydrate, 3-5 parts of antioxidant, 10-15 parts of plasticizer and 4-5 parts of crosslinking agent. The cable material related in the invention is halogen-free, and cannot release toxic gas harmful to human body if burning on ships. The cable material also meets the requirement on flame retarding property of cables on general purpose vessels, and the polymer resin material under the low temperature condition of -40 DEG C still can keep elasticity. Meanwhile, the cable material meets the requirement of the standard IEC (International Electrotechnical Commission) 60092-359 on oil-proof property of cables on ships, and also meets the requirement of the standard NEK(Norsk Electrotecnisk Komite)606 on oil-proof property of marine structures.

Description

Technical field [0001] The invention relates to a cable material, in particular to a low-temperature and oil-resistant vinyl resin cable material. The cable material of the present invention is a halogen-free vinyl resin cable material. The material made of the polymer can be applied to the cable of the ship's hull or oil drilling ship. It still maintains good elasticity at a low temperature of -40°C, and is equipped with marine cables. The required flame-retardant properties and the oil resistance required for offshore structures such as oil drilling, oil drilling ships and oil drilling structures. Background technique [0002] Oil-resistant halogen-free flame-retardant polyolefin materials are currently produced in the domestic market very little. Imported halogen-free flame-retardant and oil-resistant polyolefin materials are expensive, and not many cable manufacturers are used, generally from the Dow Chemical Company and Exxon Mobil Chemical Company. However, the cold resis...

Problems solved by technology

However, for cable sheathing materials, it is very difficult to meet the standards and NEK 606 requirements for oil resistance while having good elasticity when used at a low temperature of -40°C.
