Abstract
本发明涉及一种具有驱虫功能的塑料农用薄膜母粒的制备方法，它是以驱虫剂(4～5%的氟虫隆、2～3%的乙虫脒、2～3%的双甲脒)、1.4～1.8%的PE蜡、36～42%的硅酸钙、0.6～0.8%的硅烷偶联剂、44～50%的EVA和0.8～1.2%的紫外光吸收剂UV531为材料，经包覆分散、偶联处理、密炼塑化、挤出切粒加工而成。该塑料农用薄膜母粒以3～4%的比例添加到LDPE树脂中，通过吹塑制成厚度50～80μm薄膜，用于农田覆盖种植蔬菜瓜果类作物。由于薄膜中驱虫剂的缓慢释放，与覆盖同等厚度的LDPE薄膜相比，可有效地驱逐飞虫、叶蝉、卷叶虫、菜青虫、食心虫、红蜘蛛等害虫、达到不用或少用农药的目的，大幅度减少作物中农药残留量，有利于改善和提高作物的营养品质，促进作物早产增收。
The invention relates to a method for preparing a plastic agricultural film masterbatch with an insect repellent function, which is based on an insect repellent (4-5% of fibendron, 2-3% of ethiamiprid, 2-3% of bismuth Formamidine), 1.4-1.8% PE wax, 36-42% calcium silicate, 0.6-0.8% silane coupling agent, 44-50% EVA and 0.8-1.2% ultraviolet absorber UV531 as materials , processed by coating and dispersing, coupling treatment, banburying and plasticizing, extrusion and pelletizing. The plastic agricultural film masterbatch is added to LDPE resin at a ratio of 3 to 4%, and is blown into a film with a thickness of 50 to 80 μm, which is used for covering and planting vegetables and fruits on farmland. Due to the slow release of the insect repellant in the film, compared with the LDPE film covering the same thickness, it can effectively expel flying insects, leafhoppers, leaf rollers, cabbage caterpillars, heart worms, red spiders and other pests, achieving no or less use of pesticides The purpose is to greatly reduce the amount of pesticide residues in crops, which is conducive to improving and improving the nutritional quality of crops, and promoting premature production and income of crops.
Description
Technical field
The present invention relates to the preparation method of functional plastic film master batch, is a kind of preparation method with agglomerate of plastic agricultural film of function for expelling pests specifically.
Background technology
For a long time, insect pest is a great problem that influences crop yield always, vegetable melon and fruit class crop especially, and insect pest is more and more serious.Someone did statistics, and insect pest influences the crop yield of vegetable melon and fruit class and reaches 40-70%.For avoiding and solve the insect pest problem, the plantation family was once adopted traditional light to draw worm and is catched and killed or burn and contain aromatic hydrocarbon spirea expulsion winged insect, but the scope and the effect of expulsion insect pest are limited.And the insect of a large amount of danger to vegetables melon or fruit type crops such as tortrix moth, cabbage caterpillar, heart-eating worm, aphid, scale insect, red spider, traditional method is difficult to expulsion, mainly by spraying chemical pesticide insect pest is killed.China's agricultural chemicals year usage quantity is 80～1,000,000 tons, wherein uses the chemical pesticide aspect farm crop to account for 70%, and long-term and a large amount of use chemical pesticide has not only caused environmental pollution, and is seriously endangering the health of human body.Show according to the investigation of agricultural plant protection department; in vegetable melon and fruit class crop-planting, used the plantation family of riskiest pesticide to reach 30%; the plantation family was used chemical pesticide one time in general per 7～10 days; in harvesting time in last week, also used chemical pesticide usually; cause the pesticide residue on the vegetable melon and fruit too high, directly influenced the healthy of human consumer.For this reason, how to change existing insect-repelling method and insecticide-applying way, avoid or reduce agricultural chemicals being sprayed directly on the farm crop surface, the environmental pollution that the minimizing chemical pesticide causes has caused researchist's concern.Retrieve a large amount of patent documentations and the research paper of publishing, do not find as yet to carry out the anthelmintic relevant report by functional agricultural film.
Summary of the invention
In order to overcome present use plastic agricultural film planting vegetable melon or fruit type crops, can't adopt effective insect-repelling method, and have to farm crop are used the defective that a large amount of chemical pesticides aspect exists, the invention provides a kind of the interpolation in the plastic agricultural film course of processing through coating disperses, coupling processing, internal mixing and plasticizing, extrude the technical scheme of the agglomerate of plastic agricultural film that pelletizing processes with function for expelling pests, its technical characterictic is: with wormer (flufenoxuron, acetamiprid, amitraz), PE wax, Calucium Silicate powder, silane coupling agent, EVA and ultraviolet absorbers UV531 are material, disperse through coating, coupling processing, internal mixing and plasticizing, extrude pelletizing and be processed into agglomerate of plastic agricultural film.This master batch adds in the LDPE resin with 3～4% ratio, makes thickness 50～80um film by blow molding process, is used for farmland mulching plant vegetable melon and fruit class crop.Because the slow release of wormer in the film, compare with the ldpe film that covers condition of equivalent thickness, can expel insects such as winged insect, leafhopper, tortrix moth, cabbage caterpillar, heart-eating worm, red spider effectively, reach the purpose that uses no or little agricultural chemicals, avoid agricultural chemicals directly to contact with vegetable melon and fruit, reduce pesticide residue in the crop, help improving the nutritional quality of crop, promote the crop premature labor to increase income.
For realizing that the concrete technical scheme that the object of the invention adopted is:
The EVA of material VA content 15～18%, flufenoxuron, acetamiprid, amitraz, molecular weight are 500～800 PE wax, particle diameter is the Calucium Silicate powder of 1～5um, silane coupling agent, ultraviolet absorbers UV531.
Prescription EVA 44～50%, flufenoxuron 4～5%, acetamiprid 2～3%, amitraz 2～3%, PE wax 1.4～1.8%, Calucium Silicate powder 36～42%, silane coupling agent 0.6～0.8%, ultraviolet absorbers UV531 0.8～1.2%.
The preparation method places stirrer with flufenoxuron, acetamiprid, amitraz by formula rate, adds PE wax, control rotating speed 200r.p.m, and 72 ± 1 ℃ of temperature coat and disperse to become raw material I after 10 minutes and place Banbury mixer; Calucium Silicate powder is placed kneader, control rotating speed 500r.p.m, 105 ± 1 ℃ of temperature, mediate and add silane coupling agent after 20 minutes, coupling processing becomes raw material II and places Banbury mixer to mix with raw material I after 8 minutes, add EVA and ultraviolet absorbers UV531 again, 128 ± 2 ℃ of control Banbury mixer temperature, internal mixing and plasticizing 10 minutes; After twin screw extruder, the control barrel temperature: 125～128 ℃ in I district, 130～133 ℃ in II district, 135～138 ℃ in III district, 130～133 ℃ in IV district, 122～125 ℃ of die heads are extruded pelletizing and are formed the agglomerate of plastic agricultural film with function for expelling pests.
The master batch of the present invention's preparation adds in the LDPE resin with 3～4% ratio, makes thickness 50～80um film by blowing, and the result shows: master batch relative density: 1.2 ± 0.1g/cm
3, melt flow rate (MFR): 3～5g/10min, water content≤0.2%; The film visible light transmissivity: 83～88%, film infrared line transmitance: 30～45%, film stretching intensity 〉=12Mpa, film elongation at break 〉=300%, deworming rates 〉=90%, expelling parasite timeliness 60～80 days.
The invention has the beneficial effects as follows and adopt that three kinds of flufenoxurons, acetamiprid, amitraz are composite to be wormer, thereby improved expelling parasite scope and deworming rates; Employing EVA is a vector resin, and Calucium Silicate powder is a heat preserving agent, and (7～11um) transmitances have improved the heat-insulating property of film to reduce the film middle infrared (Mid-IR) significantly; Add ultraviolet absorbers UV531, improved the weather-resistant property of film; Adopt and coat dispersion, coupling processing technology and internal mixing and plasticizing, twin screw expressing technique, thereby improved the dispersing uniformity of wormer and Calucium Silicate powder, improve resin dedicated melt fluidity and processing characteristics, satisfy process for processing requirement of expelling parasite insulation film made and service requirements.
