Abstract
Completely degraded plastic film, the paper of using in plastic mulching is characterized in that, black pulvis and paper pulp are mixed, and after stirring, gets jelly, obtains the paper mold completely degraded plastic film with paper technology.Completely degraded plastic film is characterized in that, its constituent and weight content ratio are for example following: No. 200 solvent naphtha 78%-88%, phas 2.5%-5%, humic acid 12.5%-20%.This completely degraded plastic film can reduce groundwater evaporation more than 30, and water conservation is effective; Improve underground 30-50 centimetre of soil ground temperature 1-5 degree, the crop growth phase shifts to an earlier date 3-10 days, high insulating effect.
Description
Technical field
The present invention relates to a kind of covering, be specifically related to a kind of completely degraded plastic film and production method thereof.
Background technology
Existing plastic film is difficult to decompose in natural environment, is scattered in soil and the natural environment, has destroyed soil structure, causes the white pollution to soil and environment.
Notification number: CN1277228, the Chinese patent literature of the day for announcing: 2000.12.20 has been announced a kind of " multifunctional degradable black farm mulching ", and its components system comprises chemical fertilizer that pitch, starch, film forming agent, surfactant, stabilizing agent, water, plant growing are required and little fertilizer, agricultural chemicals, weed killer herbicide etc.This mulch film not only has general biology and light degradation function, but also can be according to the Different Crop growth needs, adjust the kind of contents of starch and agricultural chemicals, weed killer herbicide, little fertilizer and the mulch film that content obtains to be fit to Different Crop, this mulch film is owing to adopt this natural black macromolecular material of pitch in addition, improved the performance of the enhancing ground temperature of mulch film greatly, reduced the cost of degradable mulch significantly, solved of the pollution of traditional agricultural mulching well to environment, also has the insect protected weeding simultaneously, prolong the effect and the saving of work and time of fertilizer efficiency, execute the simple advantage of membrane operations.But this invention adopts pitch as important material, when use sprays, need just can dissolve dilution with hot water, and cost is higher, is difficult for promoting.
Summary of the invention
The objective of the invention is seriously polluted at existing plastic film, take a lot of work, deficiency such as time-consuming, effort, a kind of pollution-free, saving of labor be provided, saved time, a kind of completely degraded plastic film in labour-saving and production method thereof.
The objective of the invention is to realize by following technological means: completely degraded plastic film, the paper of using in plastic mulching mixes black pulvis and paper pulp, after stirring, gets jelly, obtains the paper mold completely degraded plastic film with paper technology.
Described black pulvis includes the humic acid of polyvinyl alcohol glue and 10%-15%.
Described humic acid is weathered coal or brown coal.
Completely degraded plastic film is characterized in that, its constituent and weight content ratio are for example following:
No. 200 solvent naphtha 78%-88%, phas 2.5%-5%, humic acid 12.5%-20%.
A kind of production method of completely degraded plastic film, it is characterized in that: with No. 200 solvent naphtha 78%-88%, phas2.5%-5%, humic acid 12.5%-20% is metered in the mixing reactor, in 45 ℃-55 ℃ environment, heat and reacted 18-22 minute, after the stirring, form jelly, be sprayed at then on the common paper and can use.
Described humic acid is weathered coal or brown coal.
Compared with prior art the present invention has following tangible advantage: 1, this completely degraded plastic film can reduce groundwater evaporation more than 30, and water conservation is effective.2, this completely degraded plastic film improves underground 30-50 centimetre of soil ground temperature 1-5 degree, and the crop growth phase shifts to an earlier date 3-10 days, high insulating effect.3, this completely degraded plastic film reduces bulk density of soil 6-10, and soil granular quantity increases more than 10 greater than 0.25.4, volume increase, the Different Crop amount of increase in production is more than 20.5, minimizing reduces the number of times that waters after putting seedling recruitment, overlay film, reduces agricultural chemicals, weed killer herbicide loss, and the crop maturing stage shifts to an earlier date, the quality raising.6, avoided white pollution problems.
Embodiment
The present invention is described in further detail below in conjunction with embodiment:
Completely degraded plastic film, the paper of in plastic mulching, using, differences such as shape, thickness, composition, color large or small,, so long as the paper of associating according to the present invention of in plastic mulching, using, the production method of optimized a kind of completely degraded plastic film: black pulvis and paper pulp are mixed, after stirring, get jelly, obtain the paper mold completely degraded plastic film with paper technology.Described black pulvis includes the humic acid of polyvinyl alcohol glue and 10%-15%.Described humic acid is weathered coal or brown coal.The completely degraded plastic film that this kind of method is produced, cost is low, color is black, and insulation, water conservation is effective, and degradation time is suitable fully, fine popularization.
Completely degraded plastic film is characterized in that, its constituent and weight content ratio are for example following: No. 200 solvent naphtha 78%-88%, phas 2.5%-5%, humic acid 12.5%-20%.Described humic acid is weathered coal or brown coal.A kind of production method of completely degraded plastic film, it is characterized in that: with No. 200 solvent naphtha 78%-88%, phas 2.5%-5%, humic acid 12.5%-20% is metered in the mixing reactor, in 45 ℃-55 ℃ environment, heat and reacted 18-22 minute, after the stirring, form jelly, be sprayed at then on the common paper and can use.
Two kinds of humic acid mulch films of degrading fully that the present invention relates to, in use, the paper mold completely degraded plastic film is covered in soil surface, perhaps being sprayed on the enterprising enforcement of paper uses, can form the pitchy ply of paper, can reduce the soil moisture evaporation, reduce water and soil loss, can reduce groundwater evaporation more than 30, water conservation is effective; No longer need to put seedling after the degraded, will turn to fertilizer, the granule of improving the soil increases permeability, promotes plant growing, without any pollution; The minimizing of this completely degraded plastic film reduces the number of times that waters after putting seedling recruitment, overlay film, reduces agricultural chemicals, weed killer herbicide loss, and the crop maturing stage shifts to an earlier date, the quality raising.This completely degraded plastic film reduces bulk density of soil 6-10, and soil granular quantity increases more than 10 greater than 0.25.
This completely degraded plastic film improves underground 30-50 centimetre of soil ground temperature 1-5 degree, and the crop growth phase shifts to an earlier date 3-10 days, high insulating effect.Volume increase, the Different Crop amount of increase in production is more than 20.Use the experiment effect of this humic acid mulch film of degrading fully: application such as corn, peanut, potato, garlic, vegetables originally degrade fully the humic acid mulch film than control group emerge Zao, strengthen, garlic can pass the winter; The drought resisting of corn heat and moisture preserving promotes growth.
In a word, use this completely degraded plastic film, thoroughly avoided white pollution problems.
