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 polyesters, polylactic acid（PLA）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 relatively low, molecule Measure distributed more widely, poor performance.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）It degrades with enzymatic hydrolysis.The principal degradation side of polylactic acid Formula is bulk erosion.Hydrophobic polymer passes through labile bond on main chain（C-O keys）Hydrolysis become low relative molecular weight, water 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, end carboxyl is to having hydrolyzed catalytic action.With the progress of degradation, end carboxyl amount increases, and degradation rate is accelerated.
Implementation process：
First by raw material according to configuring by weight：Including 15-60 parts of polylactic acid, poly terephthalic acid-adipic acid fourth two 40-85 parts of alcohol ester, 0.1-0.5 parts of reactive assistant, 0.1-0.5 parts of antioxidant, 0.1-0.5 parts of lubricant, ultraviolet absorber 0.1-0.5 parts and 0.1-0.5 parts of light stabilizer.
Then raw material is dried, puts agitating device after drying into and is stirred, the time is 3-5 hours, is stirred evenly After be put into comminutor and be granulated, obtain degradative plastics particle, head temperature is 110-150 DEG C, then by degradative plastics particle It is put into coextrusion film blowing machine and carries out blown film, wherein the temperature of blown film is 150 DEG C -200 DEG C, is sprayed again on packaging film after blowfilm shaping Last layer antimicrobial coating is applied, antiseptic includes 2-6 parts of cedar wood oil, 4-8 parts of chitosan, 10-20 parts of nano cupric oxide, nano oxygen Change 15-25 parts of silver, 30-50 parts of poly (hexamethylene) hydrochloride, 2,4,4 '-three 2-4 parts of chloro- 2 '-dihydroxy diphenyl ethers.
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.
