Day by day in short supply along with petroleum resources, the aggravation gradually of white pollution and Greenhouse effect, the bioabsorbable polymer material being raw material with renewable biomass resource becomes the focus of current Material Field development.Bioabsorbable polymer material is the environmentally friendly novel material of a class, main is raw material with plant, obtained as PHA (PHA) by Microbe synthesis, poly(lactic acid) (PIA) etc. is then by the chemosynthesis and obtaining again of Microbe synthesis monomer.PHBV (PHBV) is the one in PHA, it is the multipolymer of 3-hydroxybutyrate ester and 3-hydroxyl valerate, there is the characteristic such as good biological degradability, biocompatibility and Bioabsorbable, longer bio-absorbable cycle, therefore can be applicable to the fields such as such as medical material (suture, nail), thin-film material (mulch film, shopping bag, compost bag), disposable product (pen, tableware), wrapping material (particularly food product pack).
Such as, the Chinese patent that publication number is CN101508791B, publication date is 2012.10.03, application people is Xing Jinxiang discloses " a kind of production method of biodegradable plastic film ", specifically provide a kind of method using Ecoflex and PHBV to produce biodegradable plastic film, 5 ~ 50%PHBV polyhydroxybutyrate valeric acid copolyesters and 50 ~ 95%Ecoflex aliphatic aromatic atactic polyester are mixed, the more additional CaCO accounting for said mixture gross weight 5%
3this invention has following beneficial effect: its technique is simple, easy handling, the film produced is under the effect of soil microorganisms, water, carbonic acid gas and organism can be resolved into completely, pollution-free, can be widely used in agricultural mulching, packing bag (food product pack, industrial packaging) etc., be a kind of environmentfriendly products of green.But, there is certain defect in this film: when being applied to wrapping material, and its performance in thermotolerance and toughness is undesirable, reduces its range of application.
Summary of the invention:
The present invention will separate the preparation method that technology book is originally to provide a kind of wrapping material PHBV composite membrane, and the composite membrane prepared has good thermotolerance and toughness, can be applied to multiple occasion.
For separating this above-mentioned technology book, technical scheme of the present invention is:
A preparation method for wrapping material PHBV composite membrane, comprises the following steps:
(1) superfine grinding after serpentine ball mill ball milling is obtained serpentine powder, sodium stearate is dissolved in deionized water and mixes obtained modification liquid, serpentine powder is added modification liquid, be placed in water bath with thermostatic control to stir 30 minutes, take out, filter, being placed in loft drier dries to constant weight, obtains modification snake stone flour;
(2) added by the PHBV of 80-90 weight part in twin-roll plastic mixing mill and plastify 2 minutes, the modification snake stone flour of 2-6 weight part and the compatilizer of 4 weight parts are added successively twin-roll plastic mixing mill and continue plasticizing 8 minutes, thin-pass 8 times, obtains compound;
(3) compound and the compatilizer of 4 weight parts, the PTFE of 4-8 weight part to be added in Banbury mixer melt blending 12 minutes, move to twin screw extruder extruding pelletization, obtain pellet, pellet is used cast film machine casting film-forming, obtain wrapping material PHBV composite membrane.
Preferably, in step of the present invention (1), the particle diameter of serpentine powder is 3 μm.
Preferably, in step of the present invention (1), the weight ratio of serpentine powder and sodium stearate is 20:1.
Preferably, in step of the present invention (1), the temperature of water bath with thermostatic control is 80 DEG C.
Preferably, in step of the present invention (1), the temperature of loft drier is 80 DEG C.
Preferably, in step of the present invention (2), the temperature of plasticizing is 140 DEG C.
Preferably, in step of the present invention (2), compatilizer is epoxy soybean oil.
Preferably, in step of the present invention (3), the temperature of melt blending is 170 DEG C, and rotating speed is 60rpm.
Preferably, in step of the present invention (4), the extrusion temperature of twin screw extruder is 180-205 DEG C, and rotating speed is 800rpm.
