Abstract

The invention relates to the technical field of degradable materials, in particular to a degradable material and a preparation method thereof. The degradable material is prepared from the following raw materials in parts by weight: 10-20 parts of starch, 10-20 parts of polylactic acid, 1-5 parts of a compatilizer, 1-5 parts of a nucleating agent, 20-40 parts of PBAT resin, 1-3 parts of an inorganic filler, 4-12 parts of modified bamboo fibers, 1-5 parts of deacetylated chitin and 1-5 parts of a degradable additive. According to the degradable material disclosed by the invention, the deacetylated chitin and the modified bamboo fibers are used as antibacterial raw materials, the deacetylated chitin has good antibacterial activity, and meanwhile, the PBAT resin, the degradable additive and the nucleating agent are combined, so the prepared material has antibacterial properties and also has a very good self-degradation effect, and and good flexibility, bending strength and heat resistance; and compared with a pure PBAT material, the degradable material of the invention has the advantages that cost is reduced, no harm is caused to human beings and the environment and wide market prospects and good application value are achieved.

Description

technical field

[0001] The invention relates to the technical field of degradable materials, in particular to a degradable material and a preparation method thereof. Background technique

[0002] With the rapid rise of the Internet and O2O business models, the online food ordering and delivery market is growing day by day. While ordering takeaway online provides people with convenient and fast services, it also produces a large amount of disposable plastic tableware waste. The pollution of takeaway tableware has attracted more and more attention. Only 14% of the plastic packaging in the world is recycled. In addition to the loss in processing, only about 10% are effectively recycled in the end. Takeaway tableware is theoretically recyclable. However, due to its light and thin texture, it is often stained with oil and food residue If it is polluted, its recycling needs to be cleaned and collected. The labor cost required is often higher than the economic value of tableware r...
