Abstract
The invention discloses a liquid mulching film made from polyvinyl alcohol, forming agent, film-forming agent, vinyl acetate, lignin, sodium benzoate, osseocolla, cellulose sodium, dodecyldimethyl betaine, potassium humate and water; the producing method comprises the following steps of: firstly, adding water in the raw materials into a reaction tank, then adding the rest raw materials into the reaction tank, stirring while heating, preserving the heat for 90 minutes when the temperature rises to 90 DEG C, and barreling after cooling; and the film forming method comprises the following steps of: spraying 20g of the liquid mulching film per mu, diluting the liquid mulching film with water in a mass ratio of 1:4 during spraying, spraying on the surface of soil to present foam shapes, and air drying in a clear day to form a layer of white film on the surface of the soil 10 minutes after the spraying. The liquid mulching film provided by the invention has simple raw material formula, low cost, a simple production method, obvious film forming effect, low production cost and good heat preservation, moisture preservation and air permeability, and can automatically degrade into an organic fertilizer after about 90 days, thereby being accepted easily by farmers and convenient for popularization and application.
Description
Technical field the invention belongs to the agricultural mulching technical field, relates to a kind of liquid ground film and production thereof and film.
The background technology plastic film mulching cultivation can be incubated soil moisture conservation, is the effective means of the precocious volume increase of farm crop.The wide popularization and application of film-mulching cultivation technique is for developing rapidly of agricultural brought into play enormous function.But present widely used polyethylene solid mulch film is difficult to degraded, has caused huge white pollution.For overcoming this problem, at present both at home and abroad all at degradable ground of research and development membrane technique, for example Japan's development is the Biodegradable mulch of masterbatch with the regenerated cellulose, Germany development be that the photodegradation film of masterbatch and China add two degradative plastic films that treated starch makes or the like with the heat-sensitive resin in regenerated cellulose and heat-sensitive resin, overcome the above-mentioned drawback that existing polyethylene ground film is difficult to degrade effectively.But the production cost of above-mentioned degradable mulch is high especially, and inconvenience is accepted by vast farmers, is difficult to wide popularization and application.In addition, less in view of the area of effective coverage ratio of solid mulch film, the problem that often causes mulch film to waste, the direction that therefore use conveniently, degradable liquid mulch film nuisanceless, that the area of effective coverage ratio is high just becomes the continuous research and development of people.Application number is the patent application of 01130944.X, discloses a kind of multifunctional hydrolyzed mulching liquid and blending process thereof.The hydrolyzed mulching liquid of this patent application technology is made up of polyvinyl alcohol, polyacrylic acid, hydroxypropylated starch, sorbyl alcohol, Magnesium Stearate and urea raw material, employing joins polyvinyl alcohol, polyacrylic acid, hydroxypropylated starch and sorbyl alcohol in the extrusion machine, passes through room temperature and is heated to 130 ℃, 130 ℃, 110 ℃, 110 ℃ and 150 ℃/30-40
Bzr6 temperature sections; Raw material after the extruding is added Magnesium Stearate, urea and ethylene glycol more further be crushed to the fusion flocculation agent; Add quantitative water then in dissolving tank, turn on agitator slowly is sprinkled into flocculation agent and makes.This hydrolyzed mulching raw material type is more, and cost is also than higher; The method of its preparation, program are comparatively loaded down with trivial details, and production efficiency is lower.In addition, the long unconspicuous technical problem of the liquid ground film ubiquity film formation time of present domestic use is sprayed at soil surface and is the water smoke shape.
Summary of the invention the objective of the invention is to solve that there is the production cost height in prior art, the preparation method is loaded down with trivial details, production efficiency is low and the long unconspicuous technical problem of film formation time, provide a kind of liquid ground film and production thereof and film, to overcome the deficiencies in the prior art.
The objective of the invention is to realize with following technical scheme:
One, the raw material of liquid ground film of the present invention composition and quality proportioning thereof are: polyvinyl alcohol 4Kg whipping agent 1Kg membrane-forming agent 2Kg vinyl acetate between to for plastic 0.5Kg xylogen 3Kg Sodium Benzoate 100g gelatine 0.5Kg sodium cellulosate 0.5Kg Varion CDG-K 0.5Kg potassium humate 0.5Kg water 50Kg;
Two, the production method of liquid ground film of the present invention, its production process is as follows:
Earlier the water in the raw material is added in the retort, again all the other raw materials are added, stir, when treating that temperature rises to 90 ℃, be incubated 90 minutes, get final product barrelling after the cooling, promptly get liquid ground film of the present invention while heating;
Three, the film of liquid ground film of the present invention, its operating process is as follows:
Every mu of ground spraying liquid mulch film 20Kg,, during sprinkling, liquid ground film is added water by 1 to 4 mass ratio dilution, be sprayed at the soil surface show bubble by shower nozzle, spray back fine day can form one deck white film at soil surface after air-dry 10 minutes.
Liquid ground film of the present invention be suitable for emerging behind various spring, summer, the autumn proportion of crop planting preincubation, protect fertile, soil moisture conservation.Every mu needs 40 yuan of expenses, reduces by 14 yuan than existing solid plastic mulch film.This liquid ground film raw material is formed advantages of simple, price is low, preparation method technology is simple, film-formation result is obvious, and the liquid ground film cost of being produced is low, is incubated after the use, preserves moisture, good permeability, and can degrade automatically about 90 days, the degraded back becomes the humic fertilizer, is easily accepted by vast farmers, is convenient to large scale application.
Embodiment is got polyvinyl alcohol 4Kg, whipping agent 1Kg, membrane-forming agent 2Kg, vinyl acetate between to for plastic 0.5Kg, xylogen 3Kg, Sodium Benzoate 100g, gelatine 0.5Kg, sodium cellulosate 0.5Kg, Varion CDG-K 0.5Kg, potassium humate 0.5Kg and water 50Kg.
Its production technique concrete operations: earlier the water in the raw material is added in the retort, all the other raw materials are added again, stir while heating, when treating that temperature rises to 90 ℃, be incubated 90 minutes, cooling back barrelling promptly gets liquid ground film.
Its film concrete operations: every mu of ground spraying liquid mulch film 20Kg, during sprinkling, liquid ground film is added water by the dilution of 1 to 4 mass ratio, is sprayed at the soil surface show bubble by shower nozzle in the atomizer of packing into, the spray back can form one deck white film at soil surface after fine air-dry 10 minutes.
The raw material of liquid ground film of the present invention is formed and the quality proportioning is through repeatedly orthogonal test is preferred, and its production and film are through repeatedly parallel test checking.And its raw material to form all be can buy product on the market, be convenient to implement.
