Description
The present invention relates to plastics film, in more detail, is to be carrier with the common plastic film, makes insulation, preserves moisture and have the agricultural mulching and the manufacture method of the fertile function of photodissociation, weeding and Shi Wei.
At present, the mulch film that people know does not have regular photolytic effect, causes the pollution of plastic defect film to the farmland.Japan cannot not be many weed removal mulch film produced of Co., Ltd., do not possess functions such as fertilising.CN86101146A discloses a kind of multifunctional agricultural composite membrane and complex method thereof, but because tackiness agent is a polyethylene emulsion, agricultural chemicals and fertilizer etc. are covered with paint, lacquer, colour wash, etc. on plastics film, form composite membrane, the functional substance of this kind mulch film and tackiness agent can not disposablely change native boundary over to, can not get rid of the pollution of residual film, and need artificial the covering with paint, labour intensity is bigger, and steady quality is not ideal enough.
The objective of the invention is in order to overcome the deficiency of known technology, provide a kind of and can be incubated, preserve moisture and can have weeding, Shi Weifei and regular photolytic multifunctional ground-covering film, and the manufacture method of mechanize.Improve mulch film effect and economic benefit.
The present invention is achieved in that the photodissociation agent is evenly admixed in the plastic raw materials, form female plastics-production and go out to have regular photolytic plastics film, again by water-soluble tackiness agent with weedicide or/and little fertilizer etc., adhere to a surface of mulch film.The coating of application coating machine uses the DM-3 machine to carry out drying, the integral process that formation blowing, spraying, rolling are carried out synchronously.
Surface of functional substance and plastics film is closely linked, reach by water-soluble tackiness agent, usually adopt polyvinyl alcohol or condensed ethandiol true solution best, its consumption be weedicide and little fertile weight sum 2～4% for well, calculation formula is: tackiness agent weight=(weedicide weight+little fertile weight) * 2～4%.Tackiness agent adopts the water-soluble poval true solution, can make that tackiness agent is disposable to change native boundary over to.The consumption of tackiness agent is very few, can cause weedicide and the poor adhesive force of little fertilizer on mulch film, easily comes off; The tackiness agent consumption is too much, and then the mulch film surface is difficult for drying, causes two surfaces of film, all speckles with weedicide and little fertilizer, not only causes waste, has improved cost, and has influenced the multifunctional ground-covering film quality.
Multifunctional ground-covering film is to be decided by the consumption and the adding mode of photodissociation agent in the photodissociation time and the photodissociation effect in field.For improving the photodissociation effect, the photodissociation agent can be added in the Plastic Resin particle uniformly, form female plastics, its content be female plastics 4～8% for well.The photodissociation agent adopts No. 2, photodissociation agent best.The photodissociation agent content was at 4～6% o'clock, and mulch film can photodissociation become 10Cm in 80～100 days
2Little crisp fragment; Content can fragmentate at 6～8% o'clock in 60～80 days in photodissociation.If farm crop require to prolong or shorten tectorial membrane time, the content of photodissociation agent can be lower than 4% or be higher than 6%.
Drag-line selected for use by weedicide or all ear is for well, and the simetryn effect is preferable, and its content is: every square metre of mulch film contains 100～400mg and is advisable.% content is 0.0183～0.0913 drag-line by weight, 0.012～0.06 ear all.The low herbicidal effect of content is poor, and content is too high, then poisoning can occur.Little fertilizer add zinc chloride usually or/and Manganous chloride tetrahydrate or/and borax, its content is that every square metre of mulch film contains 0.1～0.2gZn, 0.1～0.15gMn, 0.02～0.1gB.% content is by weight: 1.44～1.8Zn, 1.75～2.18Mn, 0.5～0.7B.Specifically select way for use, should determine little fertile kind and quantity of adding, contain Zn as native boundary and be lower than 0.5PPM, can on mulch film, press 500g/ mu consumption and add ZnCl according to native boundary result of laboratory test
2
The invention provides two kinds of manufacture method: secondary method technology is that female plastics that will add the photodissociation agent mix with the particle plastics and add blow moulding machine, produce photolytic mocromembrane regularly, use coating machine weedicide, little fertilizer to be coated in a surface of mocromembrane then, through PM-3 machine drying, temperature control is advisable for 60 ℃～70 ℃ again.The integral process method is to add the female plastics and the particle Plastic Resin of photodissociation agent, blow out in the process of tube film through blow moulding machine, use the DM-3 machine weedicide, little fertilizer etc. to be sprayed on a surface of a film, and carry out drying, form the integral process that blowing, spraying, drying, rolling are carried out synchronously.
Effect of the present invention is remarkable, shows that mainly herbicidal effect is good, and the broadleaf weed weeding rate reaches 91～97%, and the monocotyledon weed weeding rate is 97～99%.The effect that is equivalent to artificial spraying's weedicide.Be better than the weed removal mulch film that Japan cannot not many Co., Ltd. produces, Japan only contains the clean 8mg/m of withered grass
2And this mulch film contains the clean 100～400mg/m of withered grass
22. add trace elements such as boron, zinc, manganese respectively, make little fertile film, increasing crop yield 9.1～15% increases 80 jin of peanut folder fruits through test mu, counts 33.60 yuan, as using on 4,800 ten thousand mu of crops at home, can create 29.5 hundred million yuan of benefits.3. photodissociation is respond well, in 60 days to 100 days photodissociation phases, forms fragment, and one touches promptly brokenly, does not twine crop branch stem.4. multifunctional ground-covering film, thickness is 0.007 millimeter, than 0.005 millimeter of former weed removal mulch film attenuate, has reduced material consumption and product cost, and is functional, stores to use function after 1 year and do not subtract.Can be applicable to the covering of farm crop.In addition, all belong to mechanizeding continuous operation, economize merit, laborsaving, also assurance to some extent of quality.The present invention has made marked progress than prior art, does not adopt complex method, does not use oxidic polyethylene, Polyolefin and polyethylene kind emulsion, the photodissociation agent is not mixed in emulsion, does not make by hand and smears, thereby overcome the deficiency of known technology.
Embodiment one: evenly admix in the particle plastics for No. 2 with 0.48g photodissociation agent, be made into the female plastics of 8g, then with polyvinyl resin 82g mixing, blow out mocromembrane in above ratio through blow moulding machine.
Among the aqueous solution 1500g with 1.5% polyvinyl alcohol, adding zinc chloride 150g, Manganous chloride tetrahydrate 200g, borax 250g, drag-line 150g stir into Liniment, with coating machine with the 711g Liniment, be coated on the surface of 4.5Kg mocromembrane, be dried to multifunctional ground-covering film through 60 ℃ of temperature of DM-3 machine again, the complete adhere firmly of this mulch film effective ingredient, quality is good, the effect height.
Embodiment two: with 1% polyvinyl alcohol water solution 1500g, other can be used with embodiment one product, and quality is not good, and effective ingredient has obscission.
Example three: with 1% polyvinyl alcohol water solution 3000g, other is with embodiment one.Because of water content is many, production efficiency is low on the DM-3 machine, and product is qualified.
Embodiment four: mocromembrane 228.6g, and coating 12.8g borax, 3.87g drag-line, all the other are with example one, and mulch film is qualified.
