Example Embodiment

[0047] Attached figure 1 It is a schematic diagram of the preparation method of the halogen-free flame-retardant polyethylene material of the present invention. Reference figure 1 To illustrate the preparation methods of the flame-retardant polyethylene materials of Examples 1 to 3 and Comparative Examples 3 to 4 include the following steps:

[0048] 1) Put the LDPE into a high-speed mixer (500r / min) according to the mass ratio in Table 1, cover the drum, turn on the stirring, add a proportion of diffusion oil from the oil filling port on the drum lid, stir for 1 min, and set the temperature to 50℃ ;

[0049] 2) Add the nitrogen-based flame retardant, antioxidant, and lubricant in proportion to the mixture obtained in step 1), stir for 2 minutes, and add the uniformly mixed materials from the main feed to the twin-screw extruder;

[0050] 3) The halogen-free phosphate ester flame retardant is added into the twin-screw extruder from the refueling port between the 4 to 5 sections of...

Abstract

The invention discloses a halogen-free flame-retardant polyethylene material and preparation method and application thereof. The halogen-free flame-retardant polyethylene material is prepared from, bymass, 80-95 parts of LDPE, 5-15 parts of a halogen-free phosphate ester flame retardant, 1-5 parts of a nitrogen flame retardant, 0.2-0.8 part of an antioxidant, 0.1-0.5 part of diffusion oil and 0.3-0.7 part of a lubricant. The invention also discloses the preparation method of the halogen-free flame-retardant polyethylene material, and also discloses the application of the halogen-free flame-retardant polyethylene material. The halogen-free flame-retardant polyethylene material has the advantages that the flame-retardant and mechanical properties are excellent, the flexibility of a workpiece is good, the material does not prick the hand when touched by hand, the rebound resilience is good, the material can be recycled, environmentally friendly and nontoxic, the flame resistance can reach UL94 V-2, the self-extinguishment is good, the preparation method is simple, the production cost is low, industrial large-scale production is easy, and the material is suitable for preparing simulation decorations and plug inner membranes.

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...
