Description
Technical field
The present invention relates to agricultural mulching technical field, particularly relate to a kind of shading degradable agricultural film.
Background technology
At present, film-mulching technique is widely popularized in agricultural, be applied to Semen Tritici aestivi, Oryza sativa L., corn and soybean,
In the plantation of the crop such as Sorghum vulgare Pers., Cotton Gossypii, effect of increasing production is obvious, owing to the most a large amount of mulch films used are nondegradable macromolecules
Compound, neither by microbial attack, can not decompose voluntarily.If things go on like this, insoluble dirt will necessarily be brought to descendant
Dye harm.Therefore, research degradable mulch gradually comes into one's own.Starch is the Renewable resource that nature is abundant, its nontoxic nothing
Evil, fully biodegradable, but poor mechanical property and water resistance but limit its application.Its application is restricted.
Starch is a kind of Renewable resource, and not only wide material sources are cheap, and its goods in use have the feature of environmental protection of excellence
Can, can degrade rapidly after discarding, come from nature, back to nature.But, owing to starch is a kind of highly polar crystal material,
Intramolecular also exists substantial amounts of hydrogen bond with intermolecular, and under generic condition, thermoplasticity is poor, it is difficult to machine-shaping, and obtained product
Also exist that mechanical strength is low, poor water resistance and the shortcoming such as wet strength is low, therefore, how to improve the intensity of starch material, toughness and
Water proofing property is a urgent problem of the real substituted for plastic raw material of starch based full-biodegradable material energy.By to starch
Modification, starch granules expands, and structure changes, and degree of crystallinity reduces, and has certain molecular flexibility, and good film-forming property, with
The compatibility of macromolecule resin improves, and is so greatly improved the performance of starch mulch film so that it is range of application is wider.
In " research of hydrophobic modification starch/PVA biodegradable plastic mulch film " literary composition, author is former with corn starch
Material, through carboxymethyl etherification, the double modification of crosslinking, wherein etherification temperature is 74.44 DEG C, the molar ratio of sodium hydroxide/starch
1.85, etherification time 2.33h, concentration of alcohol is 84.65%, cross-linking modified during, use epoxychloropropane as cross-linking agent,
Consumption is 0.05%, and crosslinking time is 1.0h, and sodium hydroxide concentration is 1.5%, then obtains the cross-linking carboxymethyl that thermoplasticity is stronger
Starch, recycles it and is blended with PVA, and through crosslinking, speedup, hydrophobic modification, the mechanical property of film reaches standard-required, water suction
Rate is substantially reduced, but its combination property does not also reach actually used needs, needs its further modification is met various making
By demand, to improve the mechanical performance of starch film, toughness, intensity and other attributes, expand range of application.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of shading degradable agricultural film.

Mix than ml:g1.5-2:1 according to volume mass, be subsequently placed in the thermostat water bath of 70-80 DEG C and be stirred continuously, by epoxy chloropropionate
Alkane is dissolved in appropriate alkaline liquor, all instills in starch milk, react 1-3h, use hydrochloric acid conditioning solution after completion of the reaction in 3-5min
Ph value to 6-7, stand a period of time, washing, sucking filtration, be placed in drying baker at 55 DEG C of dry 4h, prepare cross-linking carboxymethyl and form sediment
Powder；
(3) being added in deionized water by Konjac glucomannan, after being sufficiently stirred for, liter high-temperature is to 60-90 DEG C, stirs 1-2h at such a temperature
Obtain glue, then opacifier, metallic silicon power, polyacrylamide and acrylamide are added to ball milling in ball mill are uniformly dispersed, its
Middle deionized water accounts for the 3-4 times amount of powder body gross weight, then glue and liquid slurry is mixed, and adds acrylic acid methyl ester. at 40-50
Stirring reaction 50-80min at DEG C, reaction is added to drying for standby in vacuum drying oven after terminating；
(4) product prepared by step (2) is configured to the starch milk that concentration is 38-48g/L, adds product prepared by step (3)
Stirring 30-40min at 95-100 DEG C, stirring adds remaining surplus materials and continues stirring 50-60min after terminating, then will mixing
Emulsion is transferred to homogenizer 18000r/min homogenizing 5min, forms uniform film forming liquid, then by film forming liquid in 0.09MPa vacuum
Deaerate under degree 20min, casting film-forming.
Described a kind of shading degradable agricultural film, described alkaline solution is according to mass ratio by sodium hydroxide and sodium chloride
2-3:1 mixes, and is then uniformly mixing to obtain with the deionized water dissolving of gross weight 3-4 times amount.
The invention have the advantage that the present invention utilizes corn starch for raw material, through carboxymethyl etherification, the double modification of crosslinking, make
Obtaining modified corn starch, greatly add the surface group of starch, the chemical bonding effect that intermolecular existence is strong, to flowing
The viscous drag produced increases, and apparent viscosity rises, and hinders rearranging and associating between straight chain molecule in gelatinized corn starch, increases
The water-retaining property of starch low temperature disperse system, greatly reduces retrogradation and gel tendency, and improves light transmittance and reduce parent
Aqueous, meets the crops requirement to illumination, and improves Optimality and the stability of film forming, and polysaccharide has special
Long-chain helical molecular structure, stable chemical nature, filming performance is preferable, and gas barrier property is the most excellent, and moisture barrier property is poor, utilizes chemistry
Reaction makes opacifier and metallic silicon power be coated with mutually, forms effective shading and the effect of reinforcing membrane mechanical performance, and utilizes
Konjac glucomannan makes it have good dispersibility in gelatinized corn starch, does not reunites, and has given play to higher-strength and excellent light-proofness greatly,
The Environmental-protection agricultural mulch film of the improvement of the present invention, has fabulous toughness, effectively improves the degradation property of thin film, to environment without
Evil, plays good light-proofness to the crop being not required to illumination, and ruggedness is good, and the great feature of environmental protection, do not pollute the environment.
