Abstract

The invention discloses a starch-base biological environment-friendly material which is characterized by comprising the following components in parts by weight: 30-40 parts of sweet potato starch, 25-30 parts of oil seed straw powder, 20-30 parts of Carpesium abrotanoides straw powder, 11-16 parts of polypropylene glycol, 21-30 parts of gardenia flower wood dust powder, 15-20 parts of clove wood dust powder, 2-6 parts of tributyl phosphate, 30-50 parts of hydroxy cellulose solution, 2-9 parts of talcum powder and 3-5 parts of chitin chitosan alcohol. The environment-friendly material has the advantages of favorable mechanical strength, high plasticity and wide application range, and can be used for manufacturing disposable tableware and disposable packing materials.

Description

technical field [0001] The invention relates to a starch-based bio-environmental protection material. Background technique [0002] Although disposable foamed plastic tableware brings convenience to people's lives, it has caused serious white pollution to the environment. This kind of foamed tableware will take decades to hundreds of years to degrade in the soil, such as burning it The processing produces harmful gas again, which has brought serious damage to people's living environment. Foam tableware will produce toxins at a temperature of 60 degrees, which seriously damages people's health. Although some starch-based degradable materials that have appeared in recent years have solved the problem of white pollution caused by foamed plastics, these degradable materials cannot be widely used due to their poor mechanical strength and poor plasticity. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a powder-based degrada...
