Abstract
The invention discloses a black liquid state environment-friendly multifunctional mulching film which comprises the following components in percentage by weight: 20-40wt% of high concentration organic wastewater, 0-30wt% of humic acid, 3-15wt% of a polymerization film-forming agent, 30-70wt% of water, 1-3wt% of a crosslinking agent, 0-20wt% of a stabilizer and 0-20wt% of a land additive. The degradable liquid state mulching film produced by using humic acid and paper making black liquid as raw materials has double effects: temperature increase, soil moisture conservation and seedling prevention, and stronger adhesive capacity. The mulching film can bind soil particles to ideal aggregates.
Description
Technical field
The present invention relates to-kind of biodegradated polymer materal field, especially provide-kind of a kind of black liquid state environment protection multifunctional mulch film.
Background technology
Utilize the plastic film cultivation technique be this century well-known ten multi-form agriculture technology it-.Use mulch film and can satisfy farm crop at the needs of aspects such as insulation, soil moisture conservation, frost protection, maintenance fertility, thus plastic film be the main application of plastics on agricultural it-.
Early 1950s, Japan applies plastic mulching cultivation technology the earliest, and China introduced this technology in 1978 from Japan, and from the eighties, the mulch film usage quantity is in rising trend in fluctuation.Plastic film is-kind add oxidation inhibitor, anti UV agent and the high-molecular hydrocarbons made by polyethylene, have that molecular weight is big, the characteristics of stable performance, and be difficult to degraded under field conditions (factors), can be remaining 200～400 years in soil.
At present, China uses mainly is that (0.006～0.004mm, even 0.005～0.003mm) is difficult to recycling after low, the easy fragmentation of this ground film toughness, the use to the following ultra-thin mulch film of 0.012mm, discard in soil for years on end causing soil and the serious white pollution of environment.Can say so, in fact present high yield is to be based upon on the basis of sacrificing Soil capabilities-mode of production of kind of predation formula, and it is infinite to leave a legacy of trouble.At present, China's agricultural continues high-efficient development and faces huge crisis, as problems such as drought and water shortage, desertification of land, environmental pollutions, is badly in need of new technology, product innovation change traditional planting technology.And liquid-state mulch film is easy to use, should be acute strong, with low cost, and non-environmental-pollution.Therefore, such Products Development can become people's concern-individual focus undoubtedly with application.
Summary of the invention
Technical problem to be solved by this invention is: a kind of black liquid state environment protection multifunctional mulch film is provided.
The technical solution used in the present invention is:
A kind of black liquid state environment protection multifunctional mulch film comprises following component: organic wastewater with high concentration 20-40wt.%, humic acid 0-30wt.%, aggregate into film 3-15wt.%, water 30-70wt.%, linking agent 1-3wt.%, stablizer 0-20wt.% and soil additive 0-20wt.%.
Preferred scheme is, liquid agricultural film by weight by organic wastewater with high concentration 30wt.%, humic acid 10wt.%, water 40wt.%, aggregate into film 7wt.%, linking agent 2wt.%, stablizer 3wt.% and soil additive 8wt.%.
Preferred scheme is that described organic wastewater with high concentration is black liquid, marine alga waste liquid, molasses waste liquid, vinasse waste liquid or starch waste liquor etc.
Preferred scheme is that described soil additive is fertilizer and/or weedicide.
Preferred scheme is that described linking agent is the mixture (the two amount ratio 1: 2) of formaldehyde and sodium polyphosphate.
Preferred scheme is, described stablizer is in dibasic lead stearate, Zinic stearas, stearic acid pot, lead stearate, calcium stearate, the barium stearate-kind or the mixture of two or more arbitrary proportions.
Preferred scheme is, described aggregate into film be in glycerol, starch, polyvinyl alcohol, polyoxyethylene glycol, three light methylpropanes and the polypropylene phthalein amine-kind or the mixture of two or more arbitrary proportions.
Multi-functional environment-protection mulch film of the present invention has the following advantages:
(1) be the degradable liquid-state mulch film of raw material production with humic acids and black liquid, it has double effects, and the effect that heats, preserves soil moisture, keeps a full stand of seedings of existing plastic film also has stronger adhesive capacity, grogs can be coupled to desirable coacervate.
(2) adopt straw to degenerate and be decomposed into humic acids, thoroughly solved black liquid and plastic film to the pollution of soil and environment; Have again simultaneously and collect agricultural chemicals, fertilizer and plastic sheeting for farm use in the characteristics of-body, with after turn over and be pressed into soil, can become soil improvement agent.
(3) field sprays and makes film, and cost is extremely low, and saving of work and time is simple to operate, and is strong to the topography and geomorphology adaptive faculty.
When (4) farm crop or grass are emerged, without artificial seedling setting, can emerge naturally, save great amount of manpower and material resources.
Embodiment
Specifically describe below by the present invention of embodiment.
The humic acid multifunctional degradable black liquid-state mulch film is with brown coal, weathered coal or peat black liquid, marine alga waste liquid, molasses waste liquid, wine brewing waste liquid or starch waste liquor to be carried out modification, black liquor as the extractant of humic acids, is produced the needed fertilizer of soil again simultaneously.
Concrete making method is: at first be liquid raw material under the dissemination of emulsifying agent, and aggregate into film and other auxiliary agents-work forming suspension liquid.
Under 110～80 ℃ of temperature, there is the cross-linking polymerization of control to generate product.The-stage raw material adds portions additive, and blending dispersion forms suspension liquid, begins to produce cross-linking polymerization; Divide three sections at different positions additive to be added in the crosslinking reaction liquid and to control speed of response; The continuous circulation of the repeatedly suitable proportion by step of reaction, control crosslinking polymerization degree.
