Abstract
The invention discloses a preparation method of a sweet potato starch biodegradable plastic. The method comprises the following steps of: placing sweet potato starch in a reaction kettle and gradually heating, insulating for 1-2 hours and cooling and smashing to obtain a particle sweet potato starch melt; and adding the particle sweet potato starch melt, water, polyethylene glycol, a lubricant and an enhancer into a reaction kettle, heating to 80-90 DEG C, stirring and blending, and casting by a casting machine and drying to obtain the sweet potato starch biodegradable plastic. Through the above manner, the invention provides the preparation method of a sweet potato starch biodegradable plastic. In the preparation process, the melting flowing performance of plastic is increased, and the plastic obtained is better in compatibility and tensile strength. The sweet potato starch biodegradable plastic buried by outdoor soil can be quickly and completely degraded by microorganisms in soil.
Description
Technical field
The present invention relates to field of plastics processing, particularly relate to a kind of preparation method of sweet potato starch class biodegradable plastic.
Background technology
Plastic garbage is also referred to as " white pollution ", and is main because used plastics do not obtain appropriate management and processing, thereby environment is caused negative effect.Plastic garbage can cause visual pollution, the plastic refuse that is scattered in environment can damage the appearance of the city and view, as be scattered in the one time foam tableware of physical environment, railway both sides, rivers and lakes and dance in the air all over the sky or hang the super-thin plastic bag of end of the branch, bring pessimal stimulation all for people's vision.Plastic refuse hard degradation in entering physical environment also can bring long-term more serious environmental problem, so the application of degradable plastic product more and more comes into one's own.But traditional degradable plastic product consistency and tensile strength are very low, bury in soil and can not be degraded very soon, thereby contaminate environment.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of preparation method of sweet potato starch class biodegradable plastic, and the plastics that obtain have consistency and tensile strength preferably.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of preparation method of sweet potato starch class biodegradable plastic is provided, comprises that step is:
(1) sweet potato starch is put in stirring and intensification gradually in reactor, is incubated cooling after 1-2 hour and pulverizes, obtain particulate state sweet potato starch melt;
(2) described sweet potato starch melt, water, polyoxyethylene glycol, lubricant and toughener are joined in reactor, be warming up to 80-90 ℃ of blended under agitation, obtain sweet potato starch class biodegradable plastic by casting machine curtain coating and drying.
In a preferred embodiment of the present invention, described in step (1), holding temperature is 170-190 ℃.
In a preferred embodiment of the present invention, described in step (1), cooling temperature is 30-40 ℃.
In a preferred embodiment of the present invention, described in step (2), the velocity of flow of casting machine is 4-7m/min.
The invention has the beneficial effects as follows: the preparation method of sweet potato starch class biodegradable plastic of the present invention, the melt fluidity of plastics can increase in preparation process, the plastics that obtain have consistency and tensile strength preferably, bury through outdoor soil and can guarantee that described sweet potato starch class biodegradable plastic is by fast and completely degraded of the microorganism in soil.
