Abstract
The invention relates to preparation of a raw material for producing a biodegradable mulch film, in particular to a biological degradation accelerating agent which comprises the following components in percentage by weight: 12-12.5% of sodium dithiocarbamate, 18.5-22% of diethylamine, 10-12% of acetone, 5-8% of carbon disulfide, 15-18% of iron chloride, 12-14% of nickel chloride and 28-30% of water. The invention has the advantages that polyethylene molecule branched chains can be increased to enable the mulch film to be swallowed by microbes in the set time to form CO2, H2O and humus which are finally and thoroughly degraded by biologies; biodegradable mulch films capable of meeting different climate and soil environments in various regions and requirements of different crops in the period of preservation of heat and soil moisture can be manufactured, and the mulch films can be degraded in the designed life without influencing the planting of crops of the next season; and the invention builds a good foundation for producing the biodegradable mulch films.
Description
[technical field]
The present invention relates to technical field of biological material, relate to and produce the preparation of Biodegradable mulch with raw material, specifically, is a kind of biological degradation accelerating agent of producing adjustable Biodegradable mulch.
[background technology]
Agricultural mulching is the agriculture important production means after seed, chemical fertilizer, agricultural chemicals.Mulch film has the good soil moisture conservation effect that heats, and can significantly improve the output of farm crop.But,, cause the mulch film fragment to remain in the soil in a large number along with the common plastic film of extensive use.Along with the accumulation of mulch film fragment, a large amount of residual ground film destroys Soil structure, cause soil compaction, permeability variation, soil fertility to descend, have a strong impact on growing and output of farm crop, make crop production reduction.If every mu of residual mulch film in ground surpasses 22kg, farm crop are with the underproduction 25%; If every mu of residual mulch film in ground surpasses 50kg, the soil can't be cultivated, and will cause desertification, and they constitute serious threat to the Sustainable development of agricultural.
Be normal farming of solution farm crop and the contradiction between protection environment and the arable land, market presses for degradable agricultural mulching, especially the every mu of residual reclamation area, Xinjiang of 35kg and the Northwest of China of surpassing of arable land plastic film.In areas such as the extremely strict Japan of environmental requirement, Europe, North Americas, regulatable degradative plastic film all there is urgent demand.
The manufacturing technology that photodegradation, oxidative degradation, several kinds of degradative plastic films of biological degradation are arranged at present.But, because mulch film need satisfy the different insulation of different crops, the requirement of soil moisture conservation phase in the totally different weather in various places, edatope, and can degrade on time, can not shift to an earlier date, can not postpone.So degradative plastic film must be according to the requirement design degraded life-span of various places weather, edatope and different crops insulation soil moisture conservation phase, this has the technical requirements of high accuracy controlling degradation cycle to mulch film manufacturers.Because technical difficulty is big, production cost is higher, rarely has the degradative plastic film product of success so far on the market.
Because biological degradation control technique difficulty is big, production cost is higher, rarely has the market-oriented product of successfully realizing the biodegradation rate accuracy controlling so far.Therefore, produce suitable various places weather and edatope, satisfy the mulch film that the different crops insulation soil moisture conservation phase requires, need the technology of research ability accuracy controlling ground membrane degradation, development can be regulated and control the biodegradable biological degradation accelerating agent of mulch film.
[summary of the invention]
The object of the present invention is to provide and a kind ofly can regulate and control the biodegradable biological degradation accelerating agent of mulch film, can satisfy the totally different weather in various places and have the Biodegradable mulch that the different insulation soil moisture conservation phases requires with edatope and different crops so that produce.
For realizing above purpose, the technical scheme that the present invention takes is:
A kind of biological degradation accelerating agent, the weight percent of its component is:
Sulfo-amido sodium formiate: 12～12.5%;
DIETHANOL AMINE: 18～22%;
Acetone: 9～12%;
Dithiocarbonic anhydride: 4～8%;
Iron protochloride: 15～18%;
Nickelous chloride: 10～12%;
Water: 28～30%.
Described water is 30～40 ℃ zero(ppm) water.
The positively effect of biological degradation accelerating agent of the present invention is:
(1) increases Vilaterm molecule side chain, realize and to be engulfed by mikrobe in the time of setting, to make the goods film, and then form CO
2, H
2O and living weight (soil ulmin).
(2) c h bond and C-C key on the Vilaterm macromolecular chain are cut off under the attack of radical rapidly; Form Kettenreaktion continuously; The goods molecular weight sharply descends; Greatly to expose end group as much as possible, make it become the good sources of carbon of mikrobe, finally thoroughly degraded by biology.
(3) can produce the Biodegradable mulch that satisfies the totally different weather in all parts of the world, edatope and different crops insulation soil moisture conservation phase requirement; Make mulch film in life, begin degraded; Neither shift to an earlier date, also do not postpone, do not influence next crop planting in season.
[embodiment]
In the practical implementation of biological degradation accelerating agent of the present invention, prior art capable of using is taked the production of preparing burden of above-mentioned component, and the source of its raw material can be:
Sulfo-amido sodium formiate can adopt the product of Intel chemistry (Inter-chemical) company;
The product that DIETHANOL AMINE can adopt Shanghai Ling Er chemical industry ltd to produce;
The product that acetone can adopt Nanjing Chemistry Reagent Co., Ltd. to produce;
The product that dithiocarbonic anhydride, iron(ic)chloride, nickelous chloride can adopt Shanghai chemical reagent group to produce;
Water should adopt 30～40 ℃ zero(ppm) water.
Country's synthetic resins and plastic quality supervision and inspection center are 63 ℃ to the mulch film that adopts biological degradation accelerating agent of the present invention to process in the uv irradiation temperature, and intensity is 1000uw/cm
