Embodiment 1

[0024] Take 50 kg each of linear polyethylene resin and high-pressure polyethylene resin, 8 kg of silicon dioxide, 1.5 kg of cenonitrile, 1.5 kg of zinc stearate, 1.5 kg of erucamide, 3 kg of sodium lignosulfonate, and blue pigment 8 kg and 30 kg of chlorpyrifos are mixed to prepare insecticide impregnated masterbatch. Then take 6 kg of the above insecticide impregnated masterbatch and 5 kg of white pigment, mix them evenly and place them in the No. In the funnel, open the extruder, and heat up to 130-140 degrees, extrude and blow mold the raw material into a plastic film to obtain an insecticidal film / sheet product of the present invention.

Embodiment 2

[0026] Take 50 kg each of linear polyethylene resin and high-pressure polyethylene resin, 5 kg of silicon dioxide, 1 kg of cenonitrile, 1 kg of zinc stearate, 1 kg of erucamide, 2 kg of sodium lignosulfonate, and 5 kg of yellow pigment kg and 25 kg of lemongrass essential oil are mixed to prepare insecticide impregnated masterbatches. Then take 8 kg of the above insecticide impregnated masterbatch and 6 kg of yellow pigment, mix them evenly and place them in the No. In the funnel, open the extruder, and heat up to 150-160 degrees, extrude and blow mold the raw material into a plastic film to obtain an insecticidal film / sheet product of the present invention.

Embodiment 3

[0028] Take 50 kg each of linear polyethylene resin and high-pressure polyethylene resin, 10 kg of silicon dioxide, 2 kg of cenonitrile, 2 kg of zinc stearate, 2 kg of erucamide, 4 kg of sodium lignosulfonate, and blue pigment 10 kg, 20 kg of chlorpyrifos, and 15 kg of lemongrass essential oil are mixed to prepare insecticide impregnated masterbatch. Then take 4 kg of the above insecticide impregnated masterbatch and 3 kg of white pigment, mix them evenly and place them in the No. In the funnel, open the extruder, and heat up to 120-130 degrees, extrude and blow mold the raw material into a plastic film to obtain an insecticidal film / sheet product of the present invention.

[0029] In the foregoing embodiments, the thickness of the plastic film can be determined according to actual needs, that is, if it is to be made into an insecticidal film, the thickness can be selected between 15-25 microns, and if it is to be made into an insecticidal sheet, the thickness can be thicker.

Abstract

An environment protection type insecticiding film or tablet for preventing and killing pests by attaching it on the plant or fruit is proportionally prepared from linear polyethene resin, high-pressure polyethene resin, insecticide (chloropyrifos or refined lemongrass oil), and pigment. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to an agricultural insecticide and a preparation method thereof, in particular to an environment-friendly insecticidal film / sheet and a preparation method thereof. Background technique [0002] The agricultural insecticides in the prior art are generally in the form of liquid or solid granules, and are sprayed on crops during use to achieve the purpose of killing insects. The problems that this class of insecticides and their use methods exist are: 1, passive pest control, use until finding pests, often has caused losses; Accidents of poisoning due to spraying pesticides occurred; 3. The use efficiency of pesticides is low, and residues remain on plants, vegetables, fruits and in the soil, which seriously pollutes the environment. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly insecticidal film / sheet and a preparation method thereof in order to solve the above-mentio...
