Problems solved by technology

These wastes are difficult to degrade and rot in the natural environment or garbage dumps, and they are large in quantity, scattered, difficult to recycle, and seriously polluted
At present, foreign countries generally adopt three methods of landfill, incineration and recycling to deal with plastic waste. However, landfill treatment has long-term harm to limited land resources, and incineration treatment will produce a large amount of harmful gases. The utilization method not only requires the collection and sorting of plastics, but also is not economically cost-effective, and it is difficult to promote for a while. In order to solve the problem of plastic waste disposal, degradable plastic products have attracted widespread attention due to their ideal environmental adaptability.

Abstract

The invention relates to a plastic waste degradation treatment agent and a preparation method thereof, belonging to the technical field of plastic waste treatment. In the present invention, polyhydroxy nanocellulose is firstly used as a raw material, mixed with sodium silicate, added with hydrochloric acid, reacted and filtered to obtain a filter residue, and then the filter residue is reacted at a high temperature to obtain a degradation agent matrix, and then the mussel mucin liquid and the degradation agent matrix are mixed After mixing, add catechol oxidase under alkaline conditions to obtain a modified degradation agent matrix, and finally mix and react the modified degradation agent base with ferric chloride and coal powder, filter, and dry to obtain a plastic waste degradation treatment agent ,with broadly application foreground.

Description

technical field [0001] The invention relates to a plastic waste degradation treatment agent and a preparation method thereof, belonging to the technical field of plastic waste treatment. Background technique [0002] At present, the world's total plastic output has exceeded 150 million tons, and it has become the four pillar materials alongside steel, wood, and cement. However, with the increasing use of plastics, the white pollution caused by waste plastics has become a worldwide public hazard. The global "white pollution" problem has become increasingly prominent. These wastes are difficult to degrade and rot in the natural environment or garbage dumps, and they are large in quantity, scattered, difficult to recycle, and seriously polluted. At present, foreign countries generally adopt three methods of landfill, incineration and recycling to deal with plastic waste. However, landfill treatment has long-term harm to limited land resources, and incineration treatment will ...
