Abstract

The invention discloses a phosphor-nitrogen fire-retardant polyethylene composite material and a preparation method thereof. The material is composed of the following components in percentage by weight: 50% to 80% of polyethylene, 15% to 30% of phosphor-nitrogen fire retardant, 3% to 8% of fire retardant synergist, 1% to 3% of stabilizing agent, 0.5% to 2% of dispersant, 0.1% to 1% of coupling agent, and 0.1% to 1% of antioxidant. The polyethylene composite material is enhanced by adding a phosphor-nitrogen fire retardant, has a good fire retardant performance, reaches a UL94-0 fire-retardant grade, and has the advantages of little smoke, no toxicity, good durability, high thermal stability, and excellent processing property. Moreover the preparation method of the phosphor-nitrogen fire-retardant polyethylene composite material has the advantages of simpleness, practicability, and convenient operation.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a phosphorus-nitrogen flame-retardant polyethylene composite material and a preparation method thereof. Background technique [0002] Polyethylene is a light, non-toxic, thermoplastic material with excellent electrical insulation and chemical corrosion resistance. It is cheap and easy to form and process. It is widely used in electrical appliances, chemicals, food, machinery and other industries, among which it is used in wires Especially in the cable industry. At the same time, polyethylene has the disadvantage of poor flame resistance, and the cables made of it are sometimes easy to burn and cause fires under high temperature, heat generation, discharge and other conditions. Therefore, the flame retardant problem of polyethylene has gradually been paid attention to. In recent years, the call for environmental protection has been increasing. While using flame retarda...
