Implementation principle：
Biology base controllable full-degradable plastics can be divided into starch, polyesters and other classes, the technical program according to raw material point
For starch, starch is abundance, cheap natural macromolecular material, and native starch is that have crystalline texture with inside
Existing for little particle state, molecular structure has two kinds of straight chain and branch.For different plant varieties, the shape of starch granules
The ratio of state, size and amylose and amylopectin content is all different.The grain size of starch granules is mostly 15 ~ 100
µm.The chain compound that the glucose of amylose is combined with α-D-1,4 glycosidic bonds, relative molecular mass are（20~200）
x104.The connection type of each glucose unit removes α-D-1 in amylopectin, and outside 4 glycosidic bonds, there is also α-D-1,6 glycosidic bonds, phases
It is to molecular mass（100~400）x106.The property of the starch and relative molecular mass of starch, branch lengths and straight chain form sediment
Powder is related with the ratio of amylopectin.The starch of high amylose content has preferable machine more suitable for preparing plastics, resulting product
Tool performance.
Native starch is intermolecular, and there are hydrogen bonds, and dissolubility is very poor, hydrophilic but not soluble easily in water, it has highly polar knot
Brilliant property.Since there are strong hydrogen bonding effects between the macromolecule of native starch, it is difficult to direct machine-shaping.To improve its processing technology
Performance makes the method that starch loses crystallization realize generally by the hydrogen bond for opening starch interchain.There are two types of its operating methods,
One is the starch solutions that heating aqueous amount is more than 90%, and starch granules is 60~70oStart to be swollen between C, reaches 90 in temperatureoC
Later starch granules starts to burst apart, and macromolecule interchain hydrogen bond is opened, and generates gelation；Another kind is added under air-tight state
Heat plasticates and squeezes out the starch that water content is less than 28%.
Implementation process：
It then puts raw material into agitating device first to be stirred, the time is 3-5 hours, and comminutor progress is put into after stirring evenly
It is granulated, obtains degradative plastics particle, head temperature is 110-150 DEG C, and then degradative plastics particle is put into coextrusion film blowing machine
Blown film is carried out, the wherein temperature of blown film is 150 DEG C -200 DEG C.
The embodiments of the present invention have been described in detail above, but content is only the preferred embodiment of the present invention,
Should not be construed as limiting the present invention practical range, any changes and modifications in accordance with the scope of the present application,
It should all still fall within the scope of the patent of the present invention.
