Embodiment 1

[0051] Table 1 Example 1 WPC formula

[0052]

[0053] Concrete preparation is carried out according to the following steps:

[0054] (1) Dry the wood powder fibers crushed to 40-80 mesh in a drying oven at 150°C for 3 hours, so that the wood powder can completely dehumidify and remove low-molecular-weight volatile substances in the wood powder.

[0055] (2) The municipal solid waste is bag-broken and sorted by two-stage drum sieve, and further air-separated by a double-chamber multifunctional air separator to obtain mixed plastics of polyethylene, polypropylene, and polyvinyl chloride, according to the proportion The polyethylene, polypropylene and polyvinyl chloride are washed and crushed, dried and dehydrated, and granulated to obtain mixed plastic granules with a granulation size of 40-60 mesh.

[0056] (3) In a heating jacket high-speed mixer at a temperature of 150°C, first add wood flour fibers and stir for 5 minutes, then add mixed plastic particles and other addit...

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...
