Abstract
The invention discloses a starch based degradable environmentally-friendly material. The environmentally-friendly material comprises the following components, by weight, 50-60 parts of sweet potato starch, 20-25 parts of polypropylene glycol, 10-15 parts of maltose, 10-15 parts of salad oil, 2.0-3.5 parts of a degradation control agent, 5-10 parts of polycaprolactone polyhydroxybutyrate, and 3-5 parts of chitin and chitosan alcohol. The environmentally-friendly material disclosed in the invention has the advantages of good mechanical strength, strong plasticity and wide uses, and can be used for manufacturing disposable tableware and disposable wrapping materials.
Description
Technical field
The present invention relates to a kind of
CanStarch-based degradable environment-friendly materials for the manufacture of disposable tableware and disposable packaging.
Background technology
Although one time foam tableware brings convenience for people's life, but it has but caused serious white pollution to environment, this foaming plastic tableware will can be degraded through supreme a century decades in soil, as its burn processing is produced again obnoxious flavour, brought serious infringement for people's living environment.Foaming plastic tableware can produce toxin under the temperature of 60 degree, serious infringement people healthy.Although some starch-based degrading materials that occur had in recent years solved the white pollution problems that expanded plastic causes, these degradable materials are because bad mechanical strength, poor plasticity, thereby can not use widely.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of intensity high, the powder base degradable environment-friendly materials that plasticity-is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of starch-based degradable environment-friendly materials are comprised of the composition of following parts by weight:
Sweet potato starch 50-60 part, POLYPROPYLENE GLYCOL 20-25 part, maltose 10-15 part, salad oil 10-15 part, Degradation Control agent 2.0-3.5 part, poly-own endoenzyme and poly butyric ester 5-10 part, chitin chitosan alcohol 3-5 part.
Preferably,
The invention has the beneficial effects as follows: physical strength is good, plasticity-is strong, of many uses,
CanFor the manufacture of disposable tableware and disposable packaging, and environmental protection.
