[0051] Table 1 Example 1 Plastic wood formula

[0052]

[0053] The lubricant in the plastic wood of the present invention uses fatty acid amides, including stearic acid amide, oleic acid amide, and palmitic acid amide.

[0054] (1) Dry the cotton stalk fiber crushed to 40-100 mesh in a drying box at 160°C for 3 hours to completely dehumidify the cotton stalk and remove low molecular volatile matter in the cotton stalk fiber.

[0055] (2) The municipal solid waste is separated by bag breaking and picking and hanging of a two-stage drum screen, as well as further double air chamber multifunctional winnowing machine winnowing to obtain mixed plastics of polyethylene, polypropylene and polyvinyl chloride. Take polyethylene, polypropylene and polyvinyl chloride for washing and crushing, drying and dewatering and granulating to obtain mixed plastic particles, the granulation size is 40-80 mesh.

Abstract

The invention discloses a wood polymer composite prepared by using mixed plastic and cotton stalks in domestic garbage, and a method for preparing the wood polymer composite. The method is suitable for recycling urban domestic garbage. The wood polymer composite consists of the following components in percentage by mass: 35 to 45 percent of polyethylene, 4 to 7 percent of polypropylene, 7 to 12 percent of polrvinyl chloride, 33 to 40 percent of cotton stalk fiber, 5 to 8 percent of compatilizer, 0.2 to 2.4 percent of coupling agent, 0.2 to 0.5 percent of light stabilizer, 0.2 to 0.5 percent of antioxidant, 2.1 to 4.2 percent of lubricant, 1.2 to 2.8 percent of colorant, 0.1 to 0.5 percent of antistatic agent and 0.2 to 0.4 percent of deodorization sterilization preservative, wherein polyethylene, polypropylene and polrvinyl chloride are directly from the urban domestic garbage; and the effect of performing recycling and innocent treatment on the urban domestic garbage can be achieved, white pollution caused by plastic can be reduced, and the construction of environment-friendly society can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of resources, and in particular relates to plastic wood and a method prepared by using mixed plastics and cotton stalks in urban domestic waste. Background technique [0002] With the rapid development of the country's economy, the amount of urban domestic waste has increased sharply, and the problem of waste disposal is imminent. At present, my country's waste treatment mainly adopts landfill, composting and incineration. Landfills are extremely prone to producing CH-rich 4 The landfill gas will cause an explosion, and a large amount of landfill leachate will be produced, which contains heavy metals, toxic and harmful organic chemical pollutants, and a large number of virus and pathogenic bacteria. In the composting method, due to poor classification of garbage, plastic, iron, glass, etc. remain in the raw materials for fertilizer making, making the fertilizer unclean and caus...
