Abstract
The invention provides ecological-degradation plastic mulch in various specifications, which is produced through adding nanometer ecological-degradation plastic master batch in mulch production, and a production technology for preparing the same. The proportion of the nanometer ecological-degradation plastic master batch added in the ecological-degradation plastic mulch is 0.01-50 by weight percentage; other main components of the ecological-degradation plastic mulch comprise one or more of low-density polyethylene, high-density polyethylene, linear low-density polyethylene and polypropylene, and the proportion thereof is 50-99.99 by weight percentage. The preparation method of the invention is simple and flexible; the ecological-degradation plastic mulch has good usability, can be completely degraded, and can effectively solve the mulch pollution problem in the current agricultural production.
Description
Technical field
The present invention relates to a kind of ecological-degradation plastic mulch that can in physical environment, degrade and prepare the production technique that this kind ecological-degradation plastic mulch is adopted.
Background technology
China is a large agricultural country and populous nation, and agricultural problem is the grand strategy problem that is related to national economy.Mulch film is one of important substance data of agriculture prodn, and the ground Application of membrane has greatly promoted the raising of farm output and benefit, has driven the change of agriculture prodn mode and developing by leaps and bounds of agricultural productive force.China is a plastic film mulching cultivation big country; By 2005; China's membrane covering area has reached 1,350 ten thousand hectares; The mulch film usage quantity reaches 1,200,000 tons, and mulch film uses and to have covered that Xinjiang, Shandong, Shanxi, the Inner Mongol, Heilungkiang, Shaanxi, Gansu etc. high and coldly cool, 40 multiple kinds of crops of arid and semiarid zone, and presents the situation of sustainable growth.
But common agricultural mulching adopts nondegradable polyvinylidene film, so has brought many environmental problems, is not only an important source of white pollution, also the sustainable use of ploughing has been brought great threat.
In order to develop the environment-friend substitution product of non-degradable mulch film, extensively carried out the research of degradable mulch both at home and abroad.Existing degradable mulch mainly comprises: starch addition type degradative plastic film, photodegradation film, plant fiber mulch etc.Wherein, the intensity of starch addition type degradative plastic film, stretchiness, light transmission are all relatively poor, and degradation time is difficult to control, exist not to the rupture of membranes phase with regard to broken problem and the problem of not exclusively degrading of degrading; Photodegradation film receives weather effect bigger, is difficult for degraded in the time of unglazed or cloudy; Paper mulch film or numb mulch film exist that intensity is low, wind resistance rain ability, broken, the problem of suitable mechanical shop film that is prone to.Therefore, existing degradative plastic film product ubiquity defective is difficult to accepted extensively by the peasant.
Summary of the invention
The objective of the invention is to overcome the defective that above-mentioned several kinds of degradative plastic films exist; Combine its advantage simultaneously; Provide a kind of factors such as light, heat and mikrobe of can in physical environment, utilizing that the ecological-degradation plastic mulch of degraded fully takes place; It has good use properties, and can environmentally friendlyization after discarding.
To achieve these goals; Contriver of the present invention has carried out a large amount of intensive researchs; The result finds that through in the mulch film production process, adding certain amount of nano ecological-degradation plastic masterbatch, ratio is 0.01-50 (weight percentage); Be aided with corresponding complete processing simultaneously, just can produce the ecological-degradation plastic mulch that to degrade in nature (for example conditions such as sunlight, heating, mikrobe) lining.
Therefore one aspect of the present invention provides a kind of ecological-degradation plastic mulch that can be used for ecological degraded.
Another aspect of the present invention is the complete processing of above-mentioned ecological-degradation plastic mulch.

Embodiment
The invention provides a kind of ecological-degradation plastic mulch that under multiple envrionment conditionss such as light, heat and mikrobe, has degradation function; This mulch film be by in new LDPE (film grade), high density polyethylene(HDPE), linear low density polyethylene, the Vestolen PP 7052 one or more as staple, ratio is 50-99.99 (weight percentage); The nano ecological degradable plastics mother material is as the degraded added ingredients, and ratio is 0.01-50 (weight percentage).
With the mentioned component uniform mixing, be made into ecological-degradation plastic mulch through operations such as blowings again.
Under the nature environment, the degraded of molecule aspect will take place in the component of polymer in the ecological-degradation plastic mulch, and finally changed into carbonic acid gas, water and soil ulmin by the mikrobe utilization.
Embodiment 1
Component and consumption (weight percentage)
Linear low density polyethylene resin (grand celebration DFDA7042) 99
Nano ecological degradative plastics master batch (the prosperous big strong EBP-PE-M in Shandong) 1
By above-mentioned prescription various raw materials are weighed, and place impeller (Shantou City, Guangdong Province be full of the YD-GH-100A/DZ of Electric Applicance Co., Ltd) to stir 1-3 minute.Through uniform mixing; Compound is inserted (SJ-17000 of Ruian Jinda Package Machinery Co., Ltd.) in the hopper of extruding inflation film manufacturing machine; 5 heating zones are distinguished 190,195,200,200,205 degrees centigrade of design temperatures; Extrusion-blown modling becomes even tubular film (film thickness be 0.006-0.2mm all can) then, through the ecological-degradation plastic mulch that cuts, operation such as bundling is processed all size.
The ecological-degradation plastic mulch Performance Detection:
Prepare the ecological-degradation plastic mulch that thickness is 0.008mm by embodiment 1 said method, its mechanical property increases than the common plastics mulch film of stack pile.
Shown in Fig. 1-3 is the result who the ecological-degradation plastic mulch according to embodiment 1 preparation is carried out the culture of cotton field experiment.Fig. 1 is the photo according to the firm virgin state of having laid of ecological-degradation plastic mulch of embodiment 1 preparation.Ecological-degradation plastic mulch is consistent at aspect such as laying time, method and corresponding farming operation and field management and traditional mulch film, and its soil moisture conservation, to heat effect obvious.Fig. 2 is the photo of ecological-degradation plastic mulch field experiment in the time of 40 days according to embodiment 1 preparation.Ecological-degradation plastic mulch is preceding at cotton artificially applying fertilizer rupture of membranes timing node (about 60 days after the covering), and its use properties and traditional mulch film are consistent, for growing of crop provides the adapt circumstance condition.Fig. 3 is the photo of ecological-degradation plastic mulch field experiment in the time of 60 days according to embodiment 1 preparation.When cotton growth reached 2 months approximately, mulch film had been accomplished the provide protection to cotton.Ecological-degradation plastic mulch begins to degrade, and can guarantee the airiness and the permeable sponginess of cotton root system, and then promotes the good growth of cotton root system.And the non-degradable of traditional mulch film had both intercepted the water-permeable and air permeable property of cotton, needed peasant's manpower rupture of membranes again, had increased peasant burden.
Fig. 4 is a common ground film (A) and according to the comparing result of ecological-degradation plastic mulch (B) after the liquid fungus culture of embodiment 1 preparation.After the liquid fungus culture, thalline has begun growth in the culturing bottle of ecological-degradation plastic mulch, and the part thalline has formed cotton-shaped being wrapped on the plastics, explains that fungi can effectively utilize ecological-degradation plastic mulch, and short its degraded; Common plastics can't be utilized by fungi, so the thalline in the culturing bottle is not grown.
