A cold-resistant and oil-resistant flame-retardant polyvinyl chloride cable material

Abstract

The invention provides a cold-resistant oil-resistant flame-retardant polyvinyl chloride (PVC) cable material. The cold-resistant oil-resistant flame-retardant PVC cable material is prepared by using the following raw materials, by weight, 50-60 parts of PVC resin powder S-1000, 30-40 parts of PVC resin powder S-1300, 10-15 parts of nitrile butadiene rubber powder, 4-6 parts of a silicone rubber compound, 28-32 parts of dioctyl adipate, 1-2 parts of a calcium-zinc stabilizing agent, 1-3 parts of calcium stearate, 5-8 parts of epoxidized soybean oil, 20-30 parts of ammonium molybdate, 10-20 parts of copper oxide, 1-2 parts of an antioxidant 168, 1-2 parts of an antioxidant 1035, 4-6 parts of stearic acid, 15-18 parts of propylene glycol monomethyl ether acetate, 1-2 parts of aluminum nitride and 15-20 parts of a modification filler. Compared with common flam-retardant PVC cable materials, the cold-resistant oil-resistant flame-retardant PVC cable material has improved cold and oil resistances, and solves a problem of easy precipitation of a cold resistant PVC cable material plasticizer.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a cold-resistant, oil-resistant and flame-retardant polyvinyl chloride 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 f...

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.
