Abstract
A liquid-state ground film for improving soil and preventing loss of water and soil contains goudron and/or asphalt, water, cationic surfactant, stabilizer, protecting agent and additive. Its advantages are low cost, and high filming performance and stability.
Description
1, technical field
The present invention relates to a kind of liquid-state mulch film and production method thereof.
2, background technology
In agricultural production process, for make farm crop early emerge, precocious and improve output, experience in the past is a plantation back plastic covering mulch film, to improve ground temperature, keeps humidity, promotes farm crop early to germinate, early emerge, and reaches precocious and improves the purpose of output.But, adopt plastic film, when just going out soil, seedling needs manually plastic film to be pushed aside, but also the GPRS inning does not have the soil moisture conservation effect too early, crosses party and causes seedling death, even in plot, same a kind of crop of same time sowing, its seedling-growing time also is not quite similar, so when adopting plastic film to take a lot of work.In addition, plastic film is difficult for degraded, is difficult for reclaiming, and remains in not only can hinder or influence in the soil and sows next time and cause white pollution, but also can destroy Soil structure, causes crop production reduction.Therefore, CN1116635 etc. propose degradable mulch, and its main raw material is polyvinyl resin, treated starch, photosensitizers, oxygenant etc.Though can reach degradation effect, it costs an arm and a leg, make input cost increase by 2～3 times, consider to be difficult for promoting from economic aspect.
It is a kind of mulching powder material of main raw material that CN1088229 and CN1114327 propose with the polyvinyl alcohol, is sprayed at the face of land after water-soluble at the scene, forms a kind of film, it is characterized in that degradable, has avoided white pollution.
It is raw material that CN1232857 proposes with pitch, add water, cats product palmityl trimethyl ammonium chloride, anion surfactant AES, solubility promoter etc. and make bitumen emulsion, be sprayed on the surface of ploughing behind 5 times of the dilute with waters, form one deck brown or black thin film, play heating the soil moisture conservation effect and can avoid white pollution.But relatively poor because of its selected tensio-active agent emulsifying property, so large usage quantity, cost is higher, be difficult for being accepted by the peasant, and product stability and film-forming properties is poor, and it is difficult to apply.
It is raw material that CN1277228 also proposes with pitch, with cats product or anion surfactant, adds water, starch, stablizer, membrane-forming agent etc. and makes bitumen emulsion.Be sprayed on the surface of ploughing again behind 1～2 times of the dilute with water, form film, replace plastic film.But its product stability is poor, and concentration is low, transportation cost is higher, meets the very easy breakdown of emulsion of hard water during dilution.
3, summary of the invention
The present invention's purpose is in order to overcome above-mentioned shortcoming, to utilize oil by product vacuum residuum and/or pitch to be main raw material, and a kind of with low cost, liquid-state mulch film and production method thereof that concentration is higher are provided.
Liquid-state mulch film of the present invention consists of: (by weight, as follows.)
Residual oil and/or pitch 40%～75% best 51%～73%
Water 24.9%～59% best 26.9%～48.3%
Tensio-active agent 0.1%～1.0% best 0.1%～0.7%
In addition, can also add stablizer, protective material and additive, wherein stablizer add-on (by weight) is: 0.01%～1.0%, best 0.1%～0.8%; The protective material add-on is 0.01%～2.0%, best 0.02%～1.8%; The additive add-on is 0.01%～3.0%, best 0.1%～1.8%.
Wherein vacuum residuum or asphalt source are wider, comprise vacuum residuum and/or the pitch produced with various crude oil and different process; Tensio-active agent is a cationic surfactant, preferably kiber alkyl amine, alkyl diamine and/or alkyl triamine etc.; Stablizer is inorganic salt, as ammonium salt, calcium salt, magnesium salts, molysite etc.; Protective material is W-Gum, Zulkovsky starch, carboxymethyl starch, carboxymethyl cellulose, Natvosol, polyoxyethylene glycol, polymaleic anhydride, polyvinylpyrrolidone etc.; Additive comprises nutrition agent, water-holding agent, Insecticides (tech) ﹠ Herbicides (tech) etc.Nutrition agent comprises that nitrogen, phosphorus, potassium etc. help the various fertilizer of crop growth, as ammoniacal liquor, urea, potassium hydrogen phosphate etc.The product of this patent is sprayed in the surface of ploughing, and fertilizer is penetrated in the soil with water, can save the operation to crop fertilization.Water-holding agent comprises water-soluble high-molecular substances such as poly-acetate propylene, polyacrylic acid, modified polyvinyl acetate, polyacrylamide, polyvinyl alcohol, can play the drought-relief effect to a certain extent.Sterilant is the commercially available prod, as " phenyl-hexachloride ", " 1605 " etc., can kill subterranean pest-insects such as human skeleton in the soil, grub, wireworm.Weedicide is the commercially available prod, as " nitrofen ", " Diuron Tech ", " the anti-department of standing grain ", " agricultural power " etc., can suppress weed growth, saves the weeding operation.
Product performance of the present invention meet the following requirements:
Color brown or black
The outward appearance exquisiteness
Normal viscosity 25～100S
Evaporation residue content＞55Wt%
Residual content＜0.1Wt% on the sieve
Stability in storage (24h)＜1Wt%
Dilution stability (24h)＜1Wt%
Said dilution stability is with after 10 times of the emulsion dilutions, measures by the stability in storage experiment again.
The production method of product of the present invention is: get the residual oil or the pitch of predetermined weight, be heated to 120 ℃～180 ℃, the tensio-active agent that weight is in accordance with regulations weighed up is dissolved in 30 ℃～90 ℃ the water, can make the present invention's product jointly by colloidal mill.Improve its stability and film-forming properties can suitably add stablizer and protective material etc. as need, make it have functions such as nutrition, water conservation, desinsection, weeding as need, then can corresponding adding nutrition agent, water-holding agent, Insecticides (tech) ﹠ Herbicides (tech) etc.
The present invention's product can be used as liquid-state mulch film and soil conditioner, plays to heat soil moisture conservation, improves Soil structure, increases the water stability granule of soil, improves fertilizer efficiency, promotes effects such as farm crop precocity and raising output.Compare with plastic film, have preparation simple, with low cost, easy to use, save man-hour, and under the soil microorganisms effect degradable, avoid the advantages such as white pollution of plastic film.
The present invention's product stability is good, the concentration height, can reduce transportation cost, and 10 times of dilutable waters are breakdown of emulsion not, is not afraid of hard water, and good film-forming property.It is sprayed on the surface of just having sowed, arable land, form one deck brown or black thin film, can not only play the effect of mulch film, avoid white pollution, and main component vacuum residuum wherein or pitch can natural degradation be humic acids under illumination and soil microorganisms effect, ploughing under behind the soil is the fine soil improvement agent, can increase the water stability granule of soil, helps the raising of crop growth and output.This patent product also can play and heat soil moisture conservation, improve functions such as Soil structure except that having the due function of mulch film, simultaneously, also because of the additive types difference, have functions such as weeding, desinsection, water conservation, fertilizer concurrently.
In addition, this patent product also can be used for checking winds and fixing drifting sand, turf plant, prevention soil and water loss, buildings and Irrigation Ditch antiseep etc.
