Plastic wood prepared from mixed plastic in domestic garbage and wood powder, and preparation method of plastic wood

Abstract

The invention discloses a plastic wood prepared from mixed plastic in domestic garbage and wood powder, and a preparation method of the plastic wood, which are suitable for reclamation of municipal domestic waste. The plastic wood comprises the components by mass percent: 30-47% of polyethylene, 5-8% of polypropylene, 10-15% of polyvinyl chloride (PVC), 30-35% of wood powder fiber, 3-8% of compatilizer, 0.3-2.4% of coupling agent, 0.3-0.5% of light stabilizer, 0.3-0.5% of antioxidant, 2-4% of lubricating agent, 1-3% of coloring agent, 0.2-0.4% of antistatic agent and 0.2-0.3% of deodorization and sterilization preservative, wherein the polyethylene, the polypropylene and the PVC come from the municipal domestic waste. Therefore, the effect of reclamation and innocent treatment for the municipal domestic waste can be achieved, the white pollution caused by plastic is reduced, and the plastic wood contributes to creating environment-friendly society.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of resources, in particular to plastic wood prepared by using mixed plastic and wood powder in domestic garbage and a method thereof. 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 causing soil po...
