Description
Technical field
The invention belongs to Material Field, be specifically related to a kind of plastic color master grain, particularly a kind of Rhizoma Zingiberis Recens mulch film is special
With green master batch of light modulation and preparation method thereof.
Background technology
Rhizoma Zingiberis Recens is the fresh rhizome of Zingiberaceae herbaceos perennial Rhizoma Zingiberis Recens, is that relatively broad farming is planted by China
Thing.Rhizoma Zingiberis Recens have in Chinese medicine and pharmacy dissipate, preventing or arresting vomiting, the effect such as cough-relieving, Ye Shi China food processing simultaneously
With flavoring agent conventional in daily life.
Rhizoma Zingiberis Recens happiness is warm and is weak to high light, and general employing selects hillside fields and slightly cloudy plot to cultivate, but in order to expand
Big cultivated area typically now uses mulch film or the mode of canopy film cultivation.Normal transparent mulch film light transmittance is higher,
During use, mulch film difficulty reclaims.Research shows, changes light transmittance and green transmissive light component, the Ke Yishi of mulch film
Answer the requirement to illumination of the Rhizoma Zingiberis Recens growth promoter, promote Rhizoma Zingiberis Recens growth promoter, improve Ginger Yield.Directly use
Common green color masterbatch adds and produces green mulch film, has the disadvantage in that in the actual plantation application of Rhizoma Zingiberis Recens
One is that film color is easily faded along with use time lengthening, and the later stage is unable to maintain that the growth favourable to Rhizoma Zingiberis Recens growth
Luminous environment；Two is that the different colourities of color have different impacts to the ultimate output of Rhizoma Zingiberis Recens, uses merely green
The increase and decrease of Masterbatch addition cannot meet the Rhizoma Zingiberis Recens demand to transmission light quality, and the improper selection of Masterbatch can be made
Become the underproduction of Rhizoma Zingiberis Recens；After the most existing common green Masterbatch joins mulch film, due to component,
Often result in ground film strength and decline difficulty recovery, and then cause Rhizoma Zingiberis Recens production to be affected by serious.
Summary of the invention
The present invention is directed to many weak points that existing Special mulching film for ginger Masterbatch exists, it is provided that Yi Zhongquan
New Rhizoma Zingiberis Recens mulch film green master batch of special light modulation and preparation method thereof, this Masterbatch with vector resin as substrate,
With the use of the pigment chosen specially and adjuvant, it is thus achieved that a kind of mulch film special color being specifically designed for Rhizoma Zingiberis Recens cultivation
Master batch, utilize that mulching specially used intensity prepared by this Masterbatch is high, be easily recycled, not fugitive color, Rhizoma Zingiberis Recens is provided
The growth promoter of the luminous environment needed for growth and development stage, beneficially Rhizoma Zingiberis Recens, Ginger Yield significantly improve.
The concrete technical scheme of the present invention is:
The green master batch of the special light modulation of a kind of Rhizoma Zingiberis Recens mulch film, it is characterised in that: its key component is calculated as by weight:
Vector resin 60-70 part, viridine green 16-28 part, yellow uitramarine 2-15 part, titanium dioxide 0.5-4
Part, white carbon black 1-5 part, white carbon 0.5-1 part, dispersant 5-10 part；
Wherein said vector resin is one or more in LLDPE, LDPE, mLLDPE, EVA；
Described viridine green is the one in phthalocyanines organic pigment, multi-metal oxygen composite inorganic pigment A
Or two kinds；
Described yellow uitramarine is that organic yellow pigment, Titanium Dioxide Rutile Top grade composite pigment or multi-metal oxygenization are multiple
Close in inorganic pigment B one or both；
Described titanium dioxide is Rutile type titanium dioxide or anatase thpe white powder or its mixture；
Described white carbon black includes powdery white carbon black or polyethylene senior blown film black agglomerate；
Described white carbon is Subnano-class white carbon or nano-scale white carbon black；
Described dispersant is one or more in stearic acid, zinc stearate, Tissuemat E, EVA wax；
Described yellow uitramarine is 1/8-1/2 with the amount ratio of viridine green；
Described phthalocyanines organic pigment is selected from Phthalocyanine Green G or phthalocyanine green K8370 or its mixture；
Described multi-metal oxygen composite inorganic pigment A is green selected from spinel-type multi-metal oxygen composite pigment；
Described organic yellow pigment is selected from diphenyl amine organic yellow G or Fast Yellow G or its mixture；
Titanium Dioxide Rutile Top grade composite pigment is yellow selected from Titanium Dioxide Rutile Top grade composite pigment；
Multi-metal oxygen composite inorganic pigment B is yellow selected from spinel-type multi-metal oxygen composite pigment.
Why use above-mentioned compositional selecting, main reason is that:
The common used material that LLDPE, LDPE, mLLDPE and EVA are mulch film that matrix resin is selected,
Can make an addition in different TPO mulch film, and ensure good dispersibility and functional, select above-mentioned substrate
Resin raw material is easy to get and cost is relatively low.
And the organic green pigment of phthalocyanines, multi-metal oxygen composite inorganic green pigment in the pigment selected by the present invention
Viridine green, organic yellow pigment, Titanium Dioxide Rutile Top grade composite pigment or multi-metal oxygen composite inorganic pigment
It is the pigment that weatherability is higher, not fugitive color under sunshine environment；It addition, viridine green is pressed with yellow uitramarine
Compound according to aforementioned proportion so that the transmitted spectrum of mulch film changes, improve mulch film within the specific limits
Green glow and royal purple light transmission, reduce ultraviolet light transmission, it can be ensured that the need of Rhizoma Zingiberis Recens Seedling Stage interior focusing matter
Ask.
In addition, titanium dioxide in adjuvant and white carbon black advantageously reduce the light transmittance of mulch film, play shelter from heat or light,
The effect of cooling.White carbon is conducive to increasing the mechanical strength of mulch film, it is simple to mulch film reclaims after using.
In the most whole proportioning, total materials of pigment are less than 30 parts, otherwise can reduce this Masterbatch at mulch film
Dispersibility in product and mechanical strength, yellow uitramarine with the optimum proportioning scope of viridine green is
1/8-1/2, if beyond this scope, affecting light intensity and the transmittivity of green light, and finally affect Rhizoma Zingiberis Recens
The photosynthetic rate of Seedling Stage, reduces Ginger Yield.
Additionally, present invention also offers the preparation method of above-mentioned master batch, specifically comprise the following steps that
First by each component dispensing in proportion, mix homogeneously with after use again double screw extruder carry out melted altogether
Mixed pelletize, screw rod each district temperature is 170-200 DEG C, and screw speed is 80-300r/min, is drying to obtain Rhizoma Zingiberis Recens
The green master batch of the special light modulation of mulch film；
Wherein said is blended in mixing 20-40min in banbury, and banburying temperature is 150-200 DEG C.
Use above-mentioned preparation method, first the materials such as vector resin are mixed so that various storerooms
Interaction more tight, the final master batch performance obtained is more preferably.
In sum, use provided by the present invention this be specifically designed for Rhizoma Zingiberis Recens cultivate the special light modulation of mulch film green
Masterbatch, has the advantage that
1. the mulching specially used not fugitive color of preparation；
2. the luminous environment needed for Rhizoma Zingiberis Recens growth and development stage, the beneficially growth promoter of Rhizoma Zingiberis Recens, Ginger Yield are provided
Significantly improve；
3. achieve a film three (homoiothermic, moisturizing, light modulation), minimizing field operating procedure；
4. film-strength is high, be easy to recovery, reduces investment outlay；
5. Rhizoma Zingiberis Recens mulch film special light modulation Masterbatch preparation method is simple and practical, and application prospect is extensive.
