Abstract
The invention discloses a preparation method of potato starch biodegradable plastic, which comprises the following steps of: mixing and stirring 3-chloro-2-hydroxypropyltrimethylammonium chloride and a sodium hydroxide aqueous solution; spraying the mixture onto potato starch and continuing heating and stirring to obtain a potato starch floccule; mixing the potato starch floccule, cellulose and phthalate for reaction; performing tape casting of the obtained mixed solution onto a polytetrafluoroethylene square disc by a tape casting machine to form a film; and drying to obtain the potato starch biodegradable plastic. According to the preparation method of potato starch biodegradable plastic disclosed by the invention, the preparation technology is simple, the whole production process is non-toxic and harmless, a worker can work in a good working environment, the obtained potato starch biodegradable plastic can be degraded by microorganisms after use, and environmental pollution caused by plastic is effectively reduced.
Description
Technical field
The present invention relates to field of plastics processing, particularly relate to a kind of preparation method of potato starch class biodegradable plastic.
Background technology
Plastics are compared with traditional metal products, have lightweight, corrosion-resistant, moulding is easy, processing elegant in appearance, easy, low cost and other advantages, generally be applied in our life, be indispensable simultaneously.But along with increasing rapidly of plastics output, waste plastic can not in time be processed, thereby causes the pollution of environment more and more serious.The plastic garbage appropriation of land blocks rivers, hinders health, affect view, the growth that harms the crops and HUMAN HEALTH, plastic garbage have become the important factor of polluting human habitat, and therefore the biodegradable plastics goods are used more and more on a large scale now.But traditional biodegradable plastics product producing process is complicated, and preparation process can cause environmental pollution, and Working environment is unfavorable for that the workman's is healthy.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of preparation method of potato starch class biodegradable plastic, and the method preparation technology is simple, and technological process and product are pollution-free.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of preparation method of potato starch class biodegradable plastic is provided, comprises that step is:
(1) with 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride and aqueous sodium hydroxide solution mix and blend, spray mixture on potato starch and continue heated and stirred, obtain the potato starch floss;
(2) with described potato starch floss, Mierocrystalline cellulose and phthalic ester hybrid reaction, the mixing solutions that obtains is by casting machine curtain coating film forming on the polytetrafluoro alkene square plate, and oven dry obtains potato starch class biodegradable plastic.
In a preferred embodiment of the present invention, described in step (1), Heating temperature is 120-130 ℃.
In a preferred embodiment of the present invention, described in step (2), the hybrid reaction temperature is 70-90 ℃.
In a preferred embodiment of the present invention, described in step (2), drying course is to use oven for drying.
The invention has the beneficial effects as follows: the preparation method of potato starch class biodegradable plastic of the present invention, the method preparation technology is simple, whole production process is nontoxic, the workman is worked under good Working environment, the potato starch class biodegradable plastic that obtains can be degraded by microorganisms after use, has effectively reduced the pollution of plastics to environment.
