Description
Technical field:
The present invention relates to plastic sheeting production technical field, be specifically related to a kind of phosphate ester starch-soybean protein copolymerization thin film and preparation method thereof。
Background technology:
Flourish along with plastics industry, the environmental pollution that waste plastic film rubbish brings also is on the rise, and white pollution becomes the environmental problem attracted attention in the whole world。Therefore, people have to go into overdrive to develop biological degredation plastic thin film, administers plastic refuse to the brought pollution problem of environment。
Starch is a kind of abundance, cheap natural macromolecular material, also it is a kind of inexhaustible Renewable resource, it can be biodegradable in a variety of environmental conditions, final catabolite carbon dioxide and water can pass through the photosynthesis recirculation of plant, and environment will not cause any pollution。But containing great amount of hydroxy group on starch molecular chain, it is easy in strand and form hydrogen bond outside strand, therefore indissoluble, infusibility, and poor water resistance, one meets water or long-term storage easily absorbs moisture in humid air, affects its stability。
Summary of the invention:
The technical problem to be solved is in that to provide that a kind of technique is simple, production cost is low and environment amenable phosphate ester starch-soybean protein copolymerization thin film and preparation method thereof。
The technical problem to be solved adopts following technical scheme to realize:
Phosphate ester starch-soybean protein copolymerization thin film, it is characterised in that: its composition specifically includes that
Phosphate ester starch-soybean protein copolymerization thin film preparation process, it is characterised in that: specifically include following steps:
Step 1: water and disodium hydrogen phosphate are put in agitator tank by proportioning, 60 DEG C it are warming up under being stirred continuously, disodium phosphate soln is completely dissolved, add after corn starch and disodium phosphate soln being sufficiently mixed by proportioning in reactor, material stirs intensification 70-80 DEG C in the reactor, when discharge reduction to less than 20%, it is warming up to 150-200 DEG C, starch and disodium hydrogen phosphate is made to react, when the viscosity of material is more than 50Pa s, terminate reaction, cooling discharge, obtain phosphate ester starch。
Step 2: aqueous solution, lime water and soybean protein are mixed；
Step 3: the mixed solvent in step 2 is joined in bottle with the phosphate ester starch in step 1, stirring, 5-9 hour；
Step 4: heat up again, adds pentachlorophenol, waterglass, thiourea, carbon tetrachloride, and heated and stirred, heating-up temperature is 190 DEG C, duration 10 minutes；；
Step 5: then with preparing mother raw material degradable after double screw extruder extrusion, water-cooled, cutting, namely obtain aimed thin film goods through inflation film manufacturing machine blown film after。
The invention has the beneficial effects as follows: starch source of the present invention is abundant, cheap, environmentally friendly；And the plastic sheeting intensity prepared is high, production cost is low, biodegradable, can effectively alleviate white pollution problems。
Detailed description of the invention:
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with specific embodiment, the present invention is expanded on further。
Specific embodiment: phosphate ester starch-soybean protein copolymerization thin film, its composition specifically includes that disodium hydrogen phosphate 15 parts, corn starch 100 parts, soybean protein 100 parts, Oleum Terebinthinae 5 parts, 50% sodium hydrate aqueous solution 15 parts, lime water 40 parts, waterglass 30 parts, thiourea 2 parts, carbon tetrachloride 1 part, pentachlorophenol 2 parts, 200 parts of water。
Phosphate ester starch-soybean protein copolymerization thin film preparation process, specifically includes following steps:
Step 1: water and disodium hydrogen phosphate are put in agitator tank by proportioning, 60 DEG C it are warming up under being stirred continuously, disodium phosphate soln is completely dissolved, add after corn starch and disodium phosphate soln being sufficiently mixed by proportioning in reactor, material stirs intensification 70-80 DEG C in the reactor, when discharge reduction to less than 20%, it is warming up to 150-200 DEG C, starch and disodium hydrogen phosphate is made to react, when the viscosity of material is more than 50Pa s, terminate reaction, cooling discharge, obtain phosphate ester starch。
Step 2: aqueous solution, lime water and soybean protein are mixed；
Step 3: the mixed solvent in step 2 is joined in bottle with the phosphate ester starch in step 1, stirring, 5-9 hour；
Step 4: heat up again, adds pentachlorophenol, waterglass, thiourea, carbon tetrachloride, and heated and stirred, heating-up temperature is 190 DEG C, duration 10 minutes；；
Step 5: then with preparing mother raw material degradable after double screw extruder extrusion, water-cooled, cutting, namely obtain aimed thin film goods through inflation film manufacturing machine blown film after。
Phosphate ester starch prepared by embodiment-soybean protein copolymerization thin film carries out the test of mechanical property, water resistance and degradation property, and method of testing and result are as follows:
Measure hot strength and the elongation at break of thin film according to GB/T13022-1991, measure the water absorption rate of thin film according to GB/T1034-2008。
Soil buries degradation experiment: take an exsiccator, lay the thick earth of 10cm wherein, regulating water activity is 15%, film is cut into 5cm × 2cm size, dries to constant weight at 90 DEG C, then evenly spaced be buried in the earth, thin film is taken out every 5d, use distilled water flushing surface, then dry to constant weight at 90 DEG C, calculate its weight-loss ratio。
| Test event | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| Hot strength (MPa) | 40.12 | 35.17 | 38.34 |
| Elongation at break (%) | 120.78 | 138.31 | 150.45 |
| Water absorption (%) | 20% | 21% | 24% |
| Degradation time (moon) | 4.8 | 4.7 | 4.5 |
As can be seen from the above table, preferably, water absorption is suitable, and can be completely degraded at room temperature 5 months for the thin film mechanical performance that the present invention prepares, and is far superior to degradation time 9-15 month of common degradable film, thus reducing the pollution to environment。
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described。Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention。Claimed scope is defined by appending claims and equivalent thereof。
