Abstract
The invention provides an agricultural insect resistant degradable plastic film. The agricultural insect resistant degradable plastic film is prepared by coating both sides of a plastic film with an insecticide and comprises the following components in parts by weight: 40-60 parts of corn starch, 100 parts of low density polyethylene (LDPE), 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, 4.5-6.5 parts of cedar oil 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 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
The invention belongs to plastic film material field, especially a kind of agricultural pest-resistant degradable plastic film.
Background technology
Degradable films not only had the function of conventional plastic and characteristic, but also can after reaching work-ing life, by the microbial process in soil and water or by the ultraviolet effect in sunlight, division degraded in physical environment, finally reenter in ecotope with reduction form, go back to nature.The kind of domestic research and development has contained photodegradation, light-ecological film, photoxidation biological degradation, the biological degradation of high-content of starch type, high carbon acid calcium filled-type photooxidation droping, complete biodegradable etc.There is a lot of material in current degradation material market, but be roughly divided into photo-thermal degradative plastics and pure biodegradable plastic, but existing degradation products just thinks of the aspect of environment of degrading, and the practical physical characteristics demand of the finished product can not be met to the physical and mechanical properties of product and tensile property, elongation at break etc.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of agricultural pest-resistant degradable plastic film of one with more superior tensile property and elongation at break is provided.
The technical scheme that the present invention realizes object is:
A kind of agricultural pest-resistant degradable plastic film, it adopts to obtain at the double-coated insecticide of plastics film; Its component and parts by weight are:
Every square metre of film applies insecticide slurry 4-6g.
And described insecticide slurry is obtained by the raw material blending of following weight parts: polyvinyl alcohol 65-75 part, Chinese medicine deinsectization extract 3-5 part, linking agent TAIC 1-2 part, clorafin 0.3-0.5 part, alcohol ether glucoside 0.3-0.5 part;
And described oxidation inhibitor is antioxidant 1010 or irgasfos 168.
And described UV light absorber is salol or ultraviolet absorbent UV-531.
And described polyethylene wax adopts PE520.
And described Chinese medicine deinsectization extract is obtained by the raw material of following weight parts: safflower 1-2 part, Radix Sophorae Tonkinensis 2-4 part, Golden Larch Bark 1-2 part, tuber of stemona 3-5 part, root of langdu 1-2 part, Shrubalthea Flower 1-3 part, pyrethrum 1-2 part.
And described compounded mix is obtained by the raw material of following weight parts: rhombspar 6-8 part, shell 1-2 part, potassium felspar sand 5-7 part, methyl acrylate 0.1-0.2 part, polyoxyethylene nonylphenol ether 0.1-0.2 part, capsicum seed oil 0.3-0.5 part, magnesium hydroxide 3-6 part.
Advantage of the present invention and beneficial effect are:
1, oxygen barrier provided by the invention and degradable plastic film can automatic classifyings under the effect of oxygen enrichment and microorganism, film after discarded can by the degradable digestion of occurring in nature microorganism, final generation carbonic acid gas and water, can improve 40% compared with the ldpe film oxygen barrier performance of same thickness.Preparation method's technique of the present invention is simple, production efficiency is high, industrializing implementation is easy, available common plastics inflation film manufacturing machine is produced.
2, after the present invention lays, by means of even action insecticide is dissolved on ground of rainwater, the order of deinsectization is reached.Pyrethrum is the feverfew that a kind of existing higher economic worth has again ornamental value, and its root, stem, leaf, flower etc. all contain poisonous insect element material, can be used to the raw material extracting pyrethrin, in order to prepare various sterilant.
