Abstract

The invention provides a flame-retardant plastic packaging material. The flame-retardant plastic packaging material has a three-layer structure comprising an inner layer, a middle layer and an outer layer, wherein the inner layer is prepared from the following raw materials in parts by weight: 30 to 70 parts of polyethylene, 20 to 50 parts of polylactic acid, 10 to 20 parts of polyhydroxylbutyrate valerate, 8 to 20 parts of a bipolymer of epoxy chloropropane and ethylene oxide and 5 to 15 parts of an epichlorohydrin polymer; the outer layer is prepared from the following raw materials in parts by weight: 20 to 60 parts of polyethylene, 15 to 40 parts of polylactic acid, 8 to 25 parts of polyhydroxylbutyrate valerate and 8 to 25 parts of an ethylene-vinyl acetate copolymer; and the middle layer is prepared from the following raw materials in parts by weight: 30 to 60 parts of polyethylene, 20 to 40 parts of polylactic acid, 10 to 30 parts of polyhydroxylbutyrate valerate, 5 to 20 part of a bipolymer of epoxy chloropropane and ethylene oxide and 5 to 18 parts of an epichlorohydrin polymer. The flame-retardant plastic packaging material has high environment-friendly degradation characteristic and flame-retardant characteristic.

Description

technical field [0001] The invention belongs to the technical field of plastic materials, and in particular relates to a flame-retardant plastic packaging material. Background technique [0002] Polyethylene ((PE) plastic is widely used in chemical industry due to its advantages of low density, high strength, corrosion resistance, non-toxicity, excellent dielectric properties, good chemical stability, corrosion resistance, low price, and easy molding and processing. , food, medicine and other industries. However, because the garbage produced by polyethylene plastic is not easy to be degraded, it will destroy the natural environment in the process of landfill and incineration, causing great harm to the environment, and it is also harmful to the survival of human beings and various creatures. It has caused a serious threat. With the strengthening of human environmental protection awareness, various degradable plastics continue to appear. Under the action of the biological envi...
