Embodiment Construction

[0045] The present invention will be further described below in conjunction with accompanying drawing, but not as limiting the present invention:

[0046] A preparation method for producing oxidized polyethylene wax from waste PE plastic agricultural film, comprising the following steps:

[0047] A) Waste PE plastic treatment, including screening, washing, drying, and crushing processes. The specific process is to screen waste PE plastics, select pure white waste PE plastics for washing, drying, and crushing, and use them as raw materials;

[0048] B), the cracking process, the cracking process is a high temperature degradation reaction, which is a chemical reaction,

[0049] Reaction formula: [CH2-CH2] n1 High temperature, no oxygen [CH2-CH2] n2 ,

[0050] n1: unequal molecular weight, n2: ≈1800 molecular weight;

[0051] Including suction, low-temperature release, and high-temperature cracking process; in order to ensure the smooth progress of the cracking process,...

Abstract

The invention discloses a preparation method for producing oxidized polyethlene wax by waste agricultural PE (polyethylene) plastic films. The waste agricultural PE plastic films are subjected to screening, washing, drying, grinding, screening, washing, drying, low-temperature releasing under nitrogen condition, high-temperature pyrolysis, oxidation, spraying and packaging to obtain oxidized polyethlene wax. Performances of products prepared from waste agricultural PE plastic films are uniform with those of products prepared by PE resin pyrolysis oxidation, and some indexes of the products prepared from waste agricultural PE plastic films even exceed those of the products prepared by PE resin pyrolysis oxidation.

Description

technical field [0001] The invention belongs to the technical field of organic materials and relates to the recycling of waste plastics, in particular to a preparation method for producing oxidized polyethylene wax from waste PE plastic agricultural films. Background technique [0002] my country is the country that produces and uses the most agricultural plastic films. Agricultural plastic films are mainly modern agricultural covering materials such as shed film and mulch film, forage film, sunshade net, and insect net. The films used are ordinary polyvinyl chloride film, polyvinyl chloride non-drip film, ordinary polyethylene film, polyethylene non-drip film, polyethylene multifunctional composite film and EVA multifunctional composite film. At present, the annual usage of various shed films in my country is about 1.5 million tons, and the annual renewal demand is about 700,000 tons. Among them, polyethylene film is the largest consumption, and the annual renewal demand i...
