Abstract

The present invention relates to a starch base bio-degradable material and its production method of disposable tableware. Its production raw material includes starch, persulfate, hexametaphosphate, dibasic alcohol, titanium dioxide, calcium carbonate, talcum powder, titanate, polyvinyl wax, polybasic acid, polypropylene, high-density polyethylene and linear low-density polyethylene. When it is prepared, firstly 50-70% of starch can be added into high-speed mixing and stirring machine. Then the auxiliary materials are added in turn, through the processes of stirring, starch modification and mixing, discharging to blending channel, the invented product can be obtained. Said invention starch base bio-degradable material and its tableware can be quickly degraded into friendly substance for soil in three months to one year under the condition of microbial environment, and do not result in "white pollution".

Description

field of invention [0001] The invention belongs to the formulation and production process of starch-based biodegradable disposable tableware, in particular to a starch-based biodegradable material and a production method for disposable tableware. Background technique [0002] Disposable plastic tableware has the advantages of light weight, low price, and convenient use, and has become the mainstream product of disposable tableware, which has been popular for decades. While being convenient, it has caused unprecedented "white pollution" disasters. It is a great waste of non-renewable resources to use expensive processing of non-renewable petroleum resources into disposable products with only a few minutes of use value, which undermines the implementation of sustainable development strategies. In order to meet people's requirements for the use of disposable tableware, eliminate the disaster of "white pollution", and use a large amount of renewable agricultural high-yield corn...
