Problems solved by technology

The annual output of phosphogypsum in my country is about 75 million tons. The output of phosphogypsum is large. Phosphogypsum contains arsenic, copper, zinc, iron, manganese, lead, cadmium, mercury and radioactive elements, most of which are insoluble. Solid, the cost of comprehensive utilization is high, and the comprehensive utilization rate is less than 10%
Under the action of atmosphere, sunlight and oxygen, polyethylene will age, discolor, crack, become brittle or pulverized, and lose its mechanical properties

Abstract

The invention discloses a regenerated polyethylene material containing phosphogypsum. The regenerated polyethylene material comprises the following components in parts by mass: 50-70 parts of phosphogypsum; 25-45 parts of polyethylene recycled material; 10-30 parts of artemisia apiacea powder; 4-8 parts of stearic acid; 3-6 parts of methyl cellulose; 2-6 parts of epoxy resin; 0.1-0.3 part of industrial essence; 0.25-0.5 part of Chinese prickly ash; and 3-6 parts of orange peel. The preparation method comprises the following steps: calcining phosphogypsum to remove moisture, and grinding to 100-1300 meshes; screening the polyethylene recycled material, cleaning, spin-drying and pulling into pieces; mixing the phosphogypsum and the polyethylene recycled material, adding water and stirring; adding other raw materials, cutting into particles by a granulator, drawing and cooling by a drawing machine, and finally cutting into particles by the granulator according to requirements to obtain the regenerated polyethylene material containing phosphogypsum. The regenerated polyethylene material containing the phosphogypsumhas the advantages that the material has good strength and heat resistance, meets the technical requirements of regenerated polyethylene materials and is applicable to infrastructure preparation raw materials and has a wide market.

Description

technical field [0001] The invention belongs to the technical field of preparation of recycled polyethylene materials, and in particular relates to a recycled polyethylene material containing phosphogypsum and a preparation method thereof. Background technique [0002] Phosphogypsum is the solid waste generated when sulfuric acid is used to treat phosphate rock in the process of phosphoric acid production, and its main component is calcium sulfate. The annual output of phosphogypsum in my country is about 75 million tons. The output of phosphogypsum is large. Phosphogypsum contains arsenic, copper, zinc, iron, manganese, lead, cadmium, mercury and radioactive elements, most of which are insoluble. Solid, the cost of comprehensive utilization is high, and the comprehensive utilization rate is less than 10%. A large amount of phosphogypsum has been stockpiled for a long time, which not only occupies land, but also contains fluoride, free phosphoric acid, P 2 o 5 Impurities s...
