Background technology
Occupy more and more important position in people's lives along with science and technology and industrial expansion, plastics and its product
It sets, while promoting the well-being of mankind, new trouble is also brought to the mankind, most distinct issues are " white pollutions ", various
Plastic film be flooded with each corners of our lives, reason is that plastics are difficult to decompose in the natural environment.
Due to becoming increasingly conspicuous for " white pollution " problem, people begin one's study degradative plastics, and biodegradable plastic is a kind of
Energy conservation and environmental protection new material.Due to containing active group hydroxyl, ester group, the carboxyl etc. being easily decomposed by the microorganisms, when being placed in nature
In environment under certain temperature and damp condition, the effects that due to microorganism, it is easily decomposed into water and carbon dioxide, to
It goes back to nature.
Invention content
For problem mentioned above, a kind of biodegradable plastic of present invention offer and its production method,
