Insect killing film

Abstract

The invention relates to an insect killing film. The insect killing film is prepared by coating both sides of a plastic film with an insecticide and comprises the following components in parts by weight: 100 parts of polyethylene, 10-20 parts of polycarbonate, 12-15 parts of ethylene-butene polymer, 5-10 parts of polyethylene wax, 2-4 parts of antioxidant, 0.5-1 part of ultraviolet absorber, 5-8 parts of pulullan, 60-80 parts of PBM degradation material, 10-30 parts of lubricating agents and 6-8 parts of composite filler. The film per m<2> is coated with 4-6g of insecticide slurry. The oxygen isolating degradable plastic film provided by the invention has the advantages and beneficial effects that the plastic film can be automatically decomposed under the actions of rich oxygen and microorganisms; the waste films can be completely decomposed and digested by microorganisms in the natural world to finally generate carbon dioxide and water; the oxygen isolating property of the plastic film can be improved by 40% compared with the oxygen isolating properties of LDPE (low density polyethylene) films in the same thickness; a preparation method of the plastic film is simple in process and high in production efficiency, is easy to implement industrially and can be used for producing the plastic film by using a common plastic film blowing machine.

Description

technical field [0001] The invention belongs to the field of plastic film materials, in particular to an insecticidal film. Background technique [0002] Degradable films not only have the functions and characteristics of traditional plastics, but also can be split and degraded in the natural environment through the action of microorganisms in soil and water or ultraviolet rays in sunlight after reaching the end of their service life, and finally re-enter the ecology in a reduced form. environment, back to nature. Domestically developed varieties have covered photodegradation, photobiodegradation, photooxidative biodegradation, high starch content biodegradation, high calcium carbonate filled photooxygen degradation, and full biodegradation. At present, there are many materials in the degradable material market, but they are roughly divided into photothermal degradable plastics and pure biodegradable plastics.

Problems solved by technology

At present, there are many materials in the degradable material market, but they are roughly divided into photothermal degradable plastics and pure biodegradable plastics. However, the existing degradable products only consider one aspect of the degradation environment, and the physical and mechanical properties of the products are The length, etc. cannot meet the actual physical performance requirements of the final product
