Abstract

The invention discloses a halogen-free flame-retardant polyethylene material, a preparation method and application thereof. This halogen-free flame-retardant polyethylene material includes the following raw materials in parts by mass: 80-95 parts of LDPE; 5-15 parts of halogen-free phosphate flame retardant; 1-5 parts of nitrogen-based flame retardant; 0.2-0.8 parts of antioxidant parts; 0.1-0.5 parts of diffusing oil; 0.3-0.7 parts of lubricant. At the same time, the preparation method of the halogen-free flame-retardant polyethylene material is also disclosed, and the application of the halogen-free flame-retardant polyethylene material is also disclosed. The halogen-free flame-retardant polyethylene material of the present invention has excellent flame-retardant and mechanical properties, good flexibility of the product, no sticky touch, good resilience, repeated recycling, environmental protection and non-toxicity, and flame-retardant performance reaching UL94 V‑2 , good self-extinguishing property, simple preparation method, low production cost, easy industrialized large-scale production, and suitable for preparing imitation decorations and inner membranes of plugs.

Description

technical field [0001] The invention belongs to the technical field of flame retardant materials, in particular to a halogen-free flame retardant polyethylene material and its preparation method and application. Background technique [0002] Polyethylene (PE) has the advantages of odorless, non-toxic, excellent low temperature resistance, good chemical stability, resistance to most acids and alkalis, low water absorption, and excellent electrical insulation. It is widely used in chemical industry, agriculture, construction and packaging In other fields, especially the artificial PE decoration industry, the demand for polyethylene is increasing and the requirements are becoming stricter. Many products have been upgraded from meeting the requirements of indoor use to meeting the requirements of outdoor use. Polyethylene materials with good weather resistance, no fading, stable flame retardancy, halogen-free and environmental protection are the future development trend. Howeve...
