Principle:
Biology base controllable full-degradable plastics can be divided into starch, polyesters and other classes according to raw material point；
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 straight chain and two kinds of branch.For different plant varieties, the shape of starch granules The ratio of state, size and amylose and amylopectin content is all different.The partial size of starch granules is mostly in 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 (100-400) x10 to molecular mass6.The property of starch and relative molecular mass, branch lengths and the straight chain of starch 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, generally by the hydrogen bond for opening starch interchain, the method for making starch lose crystallization is realized.There are two types of its operating methods, One is the starch solution that heating aqueous amount is greater than 90%, starch granules starts to be swollen between 60~70 DEG C, reaches 90 in temperature Starch granules starts to burst apart after DEG C, and macromolecule interchain hydrogen bond is opened, and generates gelation；Another kind is added under air-tight state Heat plasticates and squeezes out starch of the water content less than 28%.
Polylactic acid (PLA) is also referred to as polylactide, belongs to polyester family, and structural formula is (- O-CHCH3-CO-) n.
The most important two kinds of polymerizations of polylactic acid are direct polymerization method and ring-opening polymerisation method.Direct polymerization method is typical Polycondensation reaction.Using the activity of lactic acid, by heating, dehydration condensation occurs between lactic acid molecules, obtains polylactic acid.It is directly poly- Legal simple production process, production cost is low, is not required to the intermediate of reaction to be separated.But the molecular weight of polylactic acid is lower, molecule Measure distributed more widely, performance is poor.Lactide ring-opening polymerisation method produces polylactic acid using two-step method.It is cyclized and is made by acid by dehydrating lactic first Then polylactic acid is made by refined lactide ring-opening polymerisation again in lactide.Polylactic acid physical force made from ring-opening polymerisation method Better performances are learned, the production cost of the method is higher than direct polymerization method.
The degradation of polylactic acid is divided into simple hydrolysis (acid-base catalysis) and enzymatic hydrolysis degradation.The principal degradation side of polylactic acid Formula is bulk erosion.Hydrophobic polymer becomes low relative molecular weight, water by the hydrolysis of labile bond on main chain (C-O key) Then soluble molecule and monomer are further degraded to water and carbon dioxide under the action of enzyme.The degradation of polylactic acid right and wrong first The hydrolysis of crystalline region, followed by crystalline region.Hydrolysis can because carboxyl there are due to accelerate.There are autocatalysis inside polylactic acid, Inside degradation speed specific surface it is fast.When degrading beginning, the hydrolysis of ester bond is isotropic in matrix.In degradation process In, carboxyl end group is to having hydrolyzed catalytic action.With the progress of degradation, carboxyl end group amount increases, and degradation rate is accelerated.
Water flea acute toxicity test
1. test is summarized
Water flea acute toxicity test compares test with degradation compost and standard compost, and detection contains degradation oxidative biological drop Solve toxic effect of the degradation compost to water flea of plastics.Degradation oxidized-biodegradable plastic usually contains respectively after biodegrade Kind metabolite, the undegraded complete product in part and inorganic matter.
The toxicity of degradation compost can be measured with survival rate of the water flea in degradation compost and standard compost.
2. test specification
This test uses OECD chemicals test rule #202 " water flea class biological activity test and the breeding examination of OECD It tests ".
3. test procedure
(1) compost eluate 1 part of compost and 4 parts of water heats 2 hours through 60 DEG C, is made.By the coefficient of dilution of this liquid It is set to 4 ×.
(2) diluted concentration determine the test coefficient of dilution be 4 ×, 8 ×, 16 ×, 32 ×, 64 × dilution.
(3) it is packed into 20ml diluent liquid in test tube, is put into 5 water fleas, 4 repetitions of each test.
(4) test temperature is 18~22 DEG C.It is protected from light.
The survival rate of water flea is detected after (5) 24 hours.If water flea is in heaven or recumbency bottom, do not lived in 10 second observation period It is dynamic, also think in heaven.
(6) if in the fresh water of standard, the death rate of water flea is more than 10%, and test is invalid.It need to test again.
Diluted concentration determines the result of trial test are as follows:
Standard fresh water: survival rate 100%
Standard compost 4 ×: survival rate 30%
Standard compost 8 ×: survival rate 70%
Standard compost 16 ×: survival rate 100%
Standard compost 32 ×: survival rate 100%
Standard compost 64 ×: survival rate 100%
Test diluted concentration be selected as 4 ×~20 ×.Such as 4 ×, 8 ×, 12 ×, 16 ×, 20 ×.Test liquid is matched System such as table 25, test carry out 24 hours.
According to test result, show that various degradation compost dilutions do not have significant adverse effect to the survival rate of water flea. When the survival rate of the degradation compost dilution that diluted concentration is 4X and 8X, water flea is greater than corresponding standard compost dilution.
The embodiments of the present invention have been described in detail above, but content is only the preferred embodiment of the present invention, It should not be considered as limiting the scope of the invention, any changes and modifications in accordance with the scope of the present application, It should still be within the scope of the patent of the present invention.
