Abstract
The invention discloses a ful- degradable liquid mulch film, taking renewable and cheap natural macromolecule humic acid, lignin and waste slag as main raw material, containing no artificial macromolecule monomer in burdening. The product is characterized by good thermal insulating, and water retention function, low cost, environment- friendly, and adjustable degradating time about 30-120 days according to different requirement. The invention is characterized in that: it effectively overcomes problem of hard degradation for normal plastic mulch film, and it can fully degrade under natural environment, and the final product is soil humic acid fertilizer and carbon dioxide and there is no harm component residual.
Description
Technical field
The present invention relates to a kind of all-degradable liquid mulch film and preparation method thereof.
Background technology
The cultivated area that is fit to membrane covering according to data China of the Ministry of Agriculture is 5.5 hundred million mu, since nineteen ninety-four annually approximately increases with 1,000 ten thousand mu speedup.
Utilizing the plastic film cultivation technique is one of well-known ten multi-form agriculture technology in this century.Using mulch film and can satisfy needs such as farm crop insulation, soil moisture conservation, frost protection, maintenance fertility, is one of plastics main application on agricultural.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 presents ascendant trend in fluctuation.Area coverage in 1981 only is 0.17 * 104hm
2.1988 year reaches 2.33 * 106hm
2, be 1.37 * 103 times of area coverage in 1981; Nineteen ninety-five reaches 6.49 * 106hm
2. be 3.82 * 103 times of area coverage in 1981; Reached 11.7 * 106hm in 2002
2, be 6.88 * 10 of area coverage in 1981
3Doubly, rate of growth is very fast.The application of plastic mulching cultivation technology has increased substantially crop yield, has promoted China's Agricultural Development, and therefore the use of plastic film is called as " White Revolution " in the agriculture production.
But, a large amount of at present plastic films that use on the China market, the overwhelming majority is the non-degradable plastics, be a kind of by polystyrene foamed, polyethylene, polypropylene, add oxidation inhibitor, uvioresistant and the high-molecular hydrocarbons (polyethylene) made, have stable performance, molecular weight reaches more than 20,000.Have only molecular weight to be reduced to below 2000, could be utilized, become water and other organic matter, and this process is difficult to degraded under field conditions (factors) by the Institute of Micro-biology in the physical environment, can be remaining 200～400 years in scholar's earth.
China's plastic film mainly uses the following ultra-thin mulch film (0.006～0.004mm. even 0.005～0.003mm) of 0.012mm at present, low, the easy fragmentation of this ground film toughness, use back are difficult to recycling, discard in soil for years on end causing to soil and serious " white pollution " of environment.
Can say so, in fact present high yield is a kind of mode of production of robbing formula that is based upon on the basis of sacrificing Soil capabilities, and it is infinite to leave a legacy of trouble.
" white pollution " that plastics cause now become a problem that influences whole world ecotope, caused the great attention of national governments.Cross legislation as South Africa, Americanologist, ban use of poorly soluble plastics bag.Simultaneously, forbid producing poorly soluble food package box and plastic tank.
Therefore, my department be that main raw material is made with extra care " all-degradable liquid mulch film " environmental protection patented technology project that forms with humic acids etc., arises at the historic moment.
