Abstract
The invention relates to the use of a high molecular polymer emulsion film as a fruit growth protective film, wherein macromolecular emulsion is synthesized through emulsion polymerization technology, then the macromolecular emulsion is used for dip-coating or spraying the young fruits, thus complete protective film can be formed on the surface of the fruits.
Description
Technical field
The present invention relates to of the application of a kind of high molecular polymer emulsion film as the fruit growing diaphragm.
Technical background
In order to improve the fruit quality, the orchard worker generally adopts the cover bag technique, but has many shortcomings in present China planting fruit trees, as: fruit soluble solids content decline 0.5-1 degree (mouthfeel is poor), bagging time-consuming (labour intensity is big), cost height; Sack is difficult for sealing, and insect very easily enters, and sealing part damage is arranged, influences defectives such as nutrition supply to fruit.
Also occur in the last few years relevant for the patent of improving the fruit bag technology, as application (patent) number be 99110086.7,01102190.X, 03201842,00113849.9 patent.Wherein the first three items patent all is to adopt diverse ways, improves or increase the function of traditional paper bag, does not solve fundamentally that orchard worker's bagging is taken a lot of work, time-consuming problem, and price all is higher than common paper plastic bag; The 4th patent is prepared into Polymer Solution with water soluble polymers such as polyvinyl alcohol, CMC, starch as base-material, young fruit is carried out dip-coating (or spraying), replace the cover bag technique, because film forming matter is not water-fast, need repeatedly spray at fruit growth period, more increased orchard worker's labour intensity and cost input, be difficult to large tracts of land and promote.
Summary of the invention
Technical problem to be solved by this invention is to propose the application of a kind of high molecular polymer emulsion film as the fruit growing diaphragm, solves the time-consuming problem of fruit bag.
The present invention adopts following technical scheme:
The synthetic macromolecule emulsion of emulsion polymerization technology carries out dip-coating to the fruit young fruit or spraying formation diaphragm is about to the application of a kind of high molecular polymer emulsion film as the fruit growing diaphragm with using.
Described emulsion polymerization is acrylic acid ester emulsion, benzene emulsion or vinegar styrene-acrylate core/shell emulsion, promptly utilize vinyl monomers such as acrylic acid and ester class thereof, styrene, vinyl acetate, adopt the polymer emulsion of the synthetic suitable growth of young of different monomers composition and consumption and different operating technology.
Add functional inorganic filling nano titanium oxide, precipitated calcium carbonate, talcum powder or nano silicon in the described emulsion polymerization.
Add nontoxic or low toxicity anti-microbial type agricultural chemicals copper sulphate, sulphur, the agent of sulphur suspensoid, sulphur deflocculant or milk of lime in the described emulsion polymerization.
Good effect of the present invention is as follows: use emulsion polymerization technology synthetic high polymer emulsion, add auxiliary agent (bactericide, bacteriostatic agent, ultraviolet screener etc.) then, with this emulsion fruit is carried out dip-coating and form diaphragm, replace traditional fruit bag technology.Evidence: because the film that this polymer forms is water-fast, fruit trees during growth period only dip-coating has once reduced labour intensity and cost input, and does not reduce the soluble solid content of fruit.By optimizing the polymer monomer prescription, the film that emulsion polymer is formed has the performances such as gas permeability of good ductility, resistance to water, weatherability and appropriateness, helps promoting and the protection fruit growth.In emulsion, introduced inorganic filler, as nano titanium oxide or precipitated calcium carbonate, talcum powder, nano silicon etc., well solved behind the emulsion film forming from clean problem, and make liquid film have functions such as good sterilization, avoidance ultraviolet ray, can also sneak into long-acting nontoxic or low toxicity anti-microbial type agricultural chemicals in the emulsion, more directly prevent that effectively fruit from being corroded by insect.
The specific embodiment
Synthesizing of the emulsion polymerization of suitable fruit growth needs: utilize vinyl monomers such as acrylic acid and ester class thereof, styrene, vinylacetate, adopt the synthetic polymer emulsion that is fit to growth of young of different monomers composition and consumption and different operating technology.Various piece role in the present invention is: synthetic polymer emulsion film forming satisfies the basic demand of fruit growth needs, and promptly liquid film will have performances such as good ductility, gas permeability, resistance to water;
In above-mentioned emulsion, introduce functional inorganic filling and nontoxic or low toxicity anti-microbial type agricultural chemicals (as copper sulphate), be diluted to suitable concentration and get final product.
Add that inorganic filler is given the good self-cleaning net work energy of liquid film, avoided ultraviolet function and sterilization, function such as antibacterial, help good fruit appearance, improve the fruit quality; The introducing of long-acting non-poisonous pesticides has increased the function of polymer liquid film insect protected, desinsection.
The concrete manufacture craft process of macromolecule emulsion
One. synthesizing of macromolecule emulsion
Dairy industry polymerization technique acrylic ester synthesizing emulsion, benzene emulsion or vinegar styrene-acrylate core/shell emulsion routinely.
Two. the introducing of inorganic filler
Under high-speed stirred, surface treated titanium dioxide (or precipitated calcium carbonate, nano silicon, talcum powder etc.) is scattered in the above-mentioned emulsion.
Three. sneaking into of long acting antibiotic agricultural chemicals
Add the milk of lime of suitable dosage and copper sulphate (or sulphur, the agent of sulphur suspensoid, sulphur deflocculant etc.) on demand in the above-mentioned emulsion that obtains, mix and get final product.
With macromolecule latex liquid product of the present invention 5～June to the dip-coating of the operatic circle fruit; emulsion can form complete diaphragm at fruit surface; increase along with fruit; film attenuation but still be kept perfectly; the needs of fruit growth had both been satisfied; prevented disease and pest; effectively avoided ultraviolet light burning again to fruit surface; help improving fruit appearance; improving the fruit quality, is example with the operatic circle, through ripe pears are tested; the pears soluble solid content is with bagging pear is unsuitable, and the operatic circle weight is greater than bagging pear and bagging pear not.
