Abstract
The invention discloses a light-biological double-degradation agricultural film, which comprises the following ingredients in percentage by weight: 81%-86% of plastic materials, 1%-3% of photosensitizer, 0.1%-0.3% of natto bacillus powder, 11%-13% of ore powder and 1%-3% of additive. The light-biological double-degradation agricultural film has the beneficial effects that: the photosensitizer, the natto bacillus powder and the ore powder are added in a polyethylene raw material for producing the agricultural film, so that the chemical structure of the agricultural film on an agricultural land can be changed (molecular weight is decreased) due to the action of natural daylight on the photosensitizer, the material strength is lowered, the phenomena of breakage and crushing occur, and the agricultural film can be quickly and effectively degraded in soil naturally after the natto bacillus powder and the ore powder are in contact with moisture in the soil.
Description
Technical field
The present invention relates to a kind of environmental protection farmland film, more precisely, relate to a kind of photo-degradable and bio-degradable environmental protection farmland film.
Background technology
The farmland film is used for having on the farm crop effect of preserving moisture, being incubated, preventing weeds, raising the output, already by a large amount of being used on the farmland of peasant.
Tradition farmland film is the film of processing with the blowing of high-molecular polythene raw material, and this film is difficult for decomposition, and shortcomings such as what is called " a century is not changed, white pollution " are arranged.
Use the farmland film; As do not reclaim, can admix in the farmland in the period of cultivating, be difficult for characteristics such as decomposition because of it; Get off all the year round and contain a large amount of cumulative plastics films in the soil; The interior water flow of soil is obstructed, influences the growth of crop root part, existing at present a large amount of farmlands can't recultivate because of accumulating a large amount of plastics films all the year round.
Use the farmland film, like manual recovery, spent time and cost of labor are too high.The mode of general recycling is discarded farmland film to be concentrated burn or bury.Produce a large amount of dense smokes, poison gas during burning; Bury and difficult the decomposition, a century is not changed.Traditional processing mode is polluted farmland, and the ruined situation of ploughing is more and more serious.
Summary of the invention
The present invention provides a kind of photo-degradable and bio-degradable environmental protection farmland film in order to solve the problem that exists in the prior art, can have been solved the pollution problem of coml farmland effectively by sunlight and biological degradation simultaneously.
For realizing above-mentioned purpose; Technical scheme of the present invention is: photo-degradable and bio-degradable environmental protection farmland film, compositions in weight percentage is: plastic material 81%～86%, photosensitizers 1%～3%, Bacillus natto powder 0.1%～0.3%, ore powder 11%～13%, auxiliary agent 1%～3%.
Preferably, said plastic material is Vilaterm, Vestolen PP 7052.
Preferably, said photosensitizers is selected from least a in cerium stearate, Zinic stearas, Magnesium Stearate, barium stearate, the Triple Pressed Stearic Acid lanthanum.
Preferably, said ore powder is selected from least a in calcite in powder, marble flour, talcum powder, the blaue fixe.
Preferably, said auxiliary agent is selected from least a in polyethylene wax, the paraffin.
Farmland film of the present invention is caused altered chemical structure (molecular weight and molecular weight) because of photosensitizers by the natural daylight effect, and the strength of materials reduces, and rhegma, fragmentation occur.Because of postactivated the disengaging of Bacillus natto powder contact wetting, effectively make farmland film natural decomposition in soil.Natural ore powder not only can reduce the cost of farmland film greatly, itself has natural cooling styling simultaneously, can make discarded farmland film when reclaiming burning, reduces burning-point, reduces combustion time, and perfect combustion does not more easily produce poisonous dense smoke during burning.If do not reclaim, directly mix meeting because of the Bacillus natto powder in the soil after the water activation disengages, play disintegration because of the existence of ore powder, make broken farmland film accelerate decompsn in soil.Reach the effect of two-way degraded by sunlight and mikrobe.(have only photodegradation, broken discarded farmland film is admixed in the farmland, loses light and just can't decompose, and film fragments still a century is not changed; Have only biological degradation, decomposition rate is fast inadequately, can't meet the time requirement of the phase of ploughing) satisfied the demand on the agricultural effectively, directly solved the farmland pollution problems.Farmland film production cost of the present invention is low, and preparation is simple, adopts traditional maturation process to get final product mass production, recyclable nontoxic, the low carbon emission reduction that recycles, burns.
Embodiment
Fig. 1 shows the synoptic diagram that farmland film of the present invention decomposes.
Fig. 2 shows carbon dioxide generating spirogram of the present invention.
Fig. 3 shows biolysis percentage of the present invention.
Embodiment
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
As shown in Figure 1; When photo bio degradation environment protection farmland film provided by the invention (1) under sunlight (6) irradiation; Because of the effect of photosensitizers (3) makes it broken, after moisture content (7) contacts appropriate time, Bacillus natto powder (4) activation that is evenly distributed in Vilaterm (2) plastic material is disengaged after; Form a large amount of holes (8); Ore powder (5) disintegration thereupon and loses original molecule and is connected and biolytic phenomenon takes place between the plastic material Vilaterm, and then reaches the purpose of using back depleted SEP environmental protection farmland film to decompose fast.
With Vilaterm 820g, mix last film forming after cerium stearate 10g, Bacillus natto powder 3g, calcite in powder 130g, the polyethylene wax 30g fusing.

With Vestolen PP 7052 820g, mix last film forming after Zinic stearas 10g, Bacillus natto powder 3g, marble flour and talcum powder 130g, the paraffin 30g fusing.
Embodiment 3
With Vilaterm and Vestolen PP 7052 mixing 840g, mix last film forming after Magnesium Stearate and barium stearate 13g, Bacillus natto powder 2g, talcum powder 125g, the paraffin 25g fusing.
Embodiment 4
With Vestolen PP 7052 860g, mix last film forming after Zinic stearas 10g, Bacillus natto powder 3g, marble flour and talcum powder 110g, the polyethylene wax 17g fusing.
Farmland film of the present invention adopts Mierocrystalline cellulose as reference material through controlled aerobic composting experiment.According to the standard of GB/T19277-2003,, gather and calculate the amount of carbon dioxide of emitting with the mixed gas of infrared carbon dioxide analyzer continuously measured experiment container outlet.Experiment shows that the artifact rate of decomposition had reached 71.7% in 45 days, (77 days) final biolysis rate 88.9% when experiment finishes.Experiment begins the MV of the amount of carbon dioxide that blank container produces in back 10 days at 50-150mg CO2/g volatile solid.
