Flame-retardant polyethylene resin and preparation method thereof

The invention discloses flame-retardant polyethylene resin and a preparation method thereof. The flame-retardant polyethylene resin is prepared from the following raw materials in percentage by weight: 6 to 15 parts of composite flame retardant master batch, 0.1 to 1 part of composite deodorant master batch, 0.5 to 5 parts of flexibilizer, 0.1 to 2 parts of processing aid, 0.5 to 5 parts of dispersant, 20 to 60 parts of low-density polyethylene and 20 to 60 parts of linear low-density polyethylene. The polyethylene resin prepared by adopting the proportion and the method disclosed by the invention can meet the B1-grade flame-retardant requirement, has no peculiar smell, can maintain various physical properties of the polyethylene resin, and can enlarge the application range of the polyethylene resin. 本发明公开了一种阻燃型聚乙烯树脂及其制备方法，所述阻燃型聚乙烯树脂包括以下重量百分比原料：复合阻燃剂母粒6-15份、复合除味剂母粒0.1-1份、增韧剂0.5-5份、加工助剂0.1-2份、分散剂0.5-5份、低密度聚乙烯20-60份及线性低密度聚乙烯20-60份。采用本发明的配比及方法制备的聚乙烯树脂能够达到B1级阻燃要求、无任何异味，且能保持聚乙烯树脂的各项物理性能，能够扩大聚乙烯树脂的应用范围。
