Abstract
The invention discloses a mulching film capable of expelling insects and a manufacturing technique thereof. The mulching film is composed of the following raw materials in parts by weight: 40-46 parts of degradable master batch, 25-30 parts of linear low density polyethylene, 25-30 parts of carbon black master batch, 10-15 parts of fluorescent powder and 0.5-1 part of liquid paraffin. The mulching film is treated by insect sex pheromones, wherein the insect sex pheromones are compounds for controlling insect male/female attraction behaviors, are sensitive and specific, and have the advantages of long action range and high attractiveness; and thus, the treated mulching film has the function of attracting female insects to lay eggs, and the eggs laid on the mulching film can not become adults, thereby reducing the quantity of pests. Since fluorescent powder is added into the mulching film, the mulching film can emit light at night so as to attract phototactic insects in the distance to come over and receive the influence of the insect sex hormones, thereby reducing the quantity of pests in a wide range. The method for attracting and killing pests does not contact plants or agricultural products, and is more economical and convenient than large-area spraying of pheromones. The mulching film is gradually photodegraded in the use process, can not pollute the soil, and thus, is environment-friendly and convenient.
Description
Technical field
The present invention relates to plastics film manufacture field, be specifically related to a kind of insect-repelling mulching film and manufacture craft thereof.
Background technology
Membrane covering is a kind of agriculture cultivation technology, have and heat, water conservation, fertilizer conservation, improve soil physico-chemical property, increase soil fertility, suppress weed growth, alleviate the effect of disease, the function reducing humidity is also had when continuous rainfall, thus promotion vine growth and development, early flowering result, the effects such as increase yield, minimizing labor cost, the use of old place film is more and more universal, but, current mulch film, to alleviate the dynamics in disease less, disinfest and mainly still sprays insecticide, very not environmentally.Invention describes a kind of insect-repelling mulching film and manufacture craft thereof, mulch film insect sex pheromone is processed, insect sex pheromone is the compound that regulation and control insect male and female attract behavior, not only sensitivity but also single-minded, operating distance is far away, incentive is strong, therefore the mulch film after process is provided with the function that temptation female insects is laid eggs, the worm's ovum produced on mulch film cannot become adult, its progeny size is significantly reduced, thus minimizing number of pest, and in mulch film, with the addition of fluorescent material, light can be sent at night, the light insect that becomes at a distance is attracted to come to accept the impact of insects hormone, thus the number of pest improved in environment on a large scale, this method insect-killing trapping does not contact plant and agricultural-food, there is no the sorrow of pesticide residue, and compare big area and spray pheromone and more save conveniently.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of insect-repelling mulching film and manufacture craft thereof.
The technical problem that the present invention solves can realize by the following technical solutions: a kind of insect-repelling mulching film, be made up of following raw material: degradation master batch 40-46 part, linear low density polyethylene 25-30 part, black masterbatch 25-30 part, fluorescent material 10-15 part, whiteruss 0.5-1 part.
A manufacture craft for insect-repelling mulching film, comprises following processing step:
(1) according to formula, the degradation master batch in allocation sheet, linear low density polyethylene, black masterbatch, fluorescent material and whiteruss mixed, heat at 120-205 DEG C, plastify;
(2) carry out extruder grain with twin screw extruder to the mixture after plasticizing, extrusion temperature is divided into 3 districts, and first district's temperature is 150 DEG C, and second district's temperature is 160 DEG C, and the 3rd district's temperature is 180 DEG C;
(3) after twin-screw extruder, the raw material single-screw extrusion machine after extruding is carried out blowfilm shaping, during blown film, charge temperature is 75 DEG C, and compression plasticization temperature is 95 ~ 115 DEG C, and blow-up ratio is 1:3, and pulling speed is 4m/min, and length-to-diameter ratio is 1:50;
(4) after shaping, film is cooled, cooled film is placed in insect pheromone after soaking 3-5 days and takes out, obtain insect-repelling mulching film finished product.
Preferably, described insect pheromone is insect sex pheromone.
Beneficial effect is: the present invention is a kind of insect-repelling mulching film and manufacture craft thereof, mulch film insect sex pheromone is processed, insect sex pheromone is the compound that regulation and control insect male and female attract behavior, not only sensitivity but also single-minded, operating distance is far away, incentive is strong, therefore the mulch film after process is provided with the function that temptation female insects is laid eggs, the worm's ovum produced on mulch film cannot become adult, its progeny size is significantly reduced, thus minimizing number of pest, and in mulch film, with the addition of fluorescent material, light can be sent at night, the light insect that becomes at a distance is attracted to come to accept the impact of insects hormone, thus the number of pest improved in environment on a large scale, this method insect-killing trapping does not contact plant and agricultural-food, there is no the sorrow of pesticide residue, and compare big area and spray pheromone and more save conveniently, and add degradation master batch in mulch film, mulch film can be made in use gradually by photodegradation, can not contaminated soil, environment friendly convenient.
Embodiment
The following detailed description of the preferred embodiment of the present invention.
The embodiment of a kind of insect-repelling mulching film of the present invention and manufacture craft thereof: a kind of insect-repelling mulching film, be made up of following raw material: degradation master batch 40-46 part, linear low density polyethylene 25-30 part, black masterbatch 25-30 part, fluorescent material 10-15 part, whiteruss 0.5-1 part.
A kind of manufacture craft of insect-repelling mulching film, comprise following processing step: the degradation master batch in allocation sheet, linear low density polyethylene, black masterbatch, fluorescent material and whiteruss mix according to formula by (1), heat at 120-205 DEG C, plastify; (2) carry out extruder grain with twin screw extruder to the mixture after plasticizing, extrusion temperature is divided into 3 districts, and first district's temperature is 150 DEG C, and second district's temperature is 160 DEG C, and the 3rd district's temperature is 180 DEG C; (3) after twin-screw extruder, the raw material single-screw extrusion machine after extruding is carried out blowfilm shaping, during blown film, charge temperature is 75 DEG C, and compression plasticization temperature is 95 ~ 115 DEG C, and blow-up ratio is 1:3, and pulling speed is 4m/min, and length-to-diameter ratio is 1:50; (4) after shaping, film is cooled, cooled film is placed in insect pheromone after soaking 3-5 days and takes out, obtain insect-repelling mulching film finished product.Described insect pheromone is insect sex pheromone.
