Abstract
The invention discloses a kind of degradable weeding plastic films.The degradable weeding plastic film includes in parts by weight:70 100 parts of polylactic acid, 40 60 parts of polyethylene, 13 parts of nitrofen, 10 15 parts of paraffin.The degradable weeding plastic film preparation method is to mix raw material in proportion, is heated through finished product machinery, dry high-speed kneading, then blow molding.The content of nitrofen is 40 100mg/m in plastic film prepared by the present invention2.Plastic film produced by the present invention not only has preferable moisturizing, heat insulation function, can also degrade, while having weeding function.Simple production process is suitble to large-scale industrial production.
Description
Technical field
The present invention relates to plastic applications, and in particular to a kind of not only to have degraded but also can be with the plastic film of weeding.
Background technology
Plastic film has the function of moisture-heat preservation, be conducive to crops growth and development and improve crops yield and
Economic benefit.China is populous nation, and the agricultural product amount needed is big, and development and the application of ground membrane technology have been greatly facilitated China's agriculture
The development of industry and the raising of crops product.
At the same time, the extensive application of plastic film also results in a large amount of " white pollution ", and these non-degradable modelings
Material can lead to problems such as soil hardening, poor air permeability, soil fertility decline, and then can influence growth and development and the yield of crops.Cause
This, exploitation environment-friendly type degradable multifunctional plastic mulch is one of the important channel for solving to restrict agricultural sustainable development.
Invention content
(1) the technical issues of solving
In view of the deficiencies of the prior art, it the present invention provides a kind of degradable weeding plastic film, solves at present mostly
The problem of number plastic film cannot degrade, while can be a kind of functional degradation plastic mulch with weeding.
(2) technical solution
To achieve the above object, the present invention provides the following technical solutions：A kind of degradable weeding plastic film.
A kind of raw material of degradable weeding plastic film includes by weight：
Preferably, a kind of degradable weeding plastic film, main preparation process are：Raw material is mixed in proportion, through finished product
Machinery heating, dry high-speed kneading, then blow molding.
Preferably, the content of nitrofen is 40-100mg/m in the plastic film of the preparation2, and use 30-40 days
Afterwards, the content of nitrofen is zero in mulch.
(3) advantageous effect
The present invention provides a kind of degradable weeding plastic films, have following advantageous effect：
(1) not only it can also make preparation with heat and moisture preserving containing a large amount of polylactic acid in present invention process formula
Plastic film has degradation capability, environmental-friendly.
(2) nitrofen is used in present invention process formula, is a kind of herbicidal active component, with making plastics produced by the present invention
Film has weeding function.
(3) simple production process of the present invention is suitble to large-scale industrial production.
Specific implementation mode
Below in conjunction with the embodiment of the present invention, technical solution in the embodiment of the present invention is clearly and completely retouched
It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Embodiment 1
It is prepared by a kind of degradable weeding plastic film, the raw material below degradable weeding plastic film by weight：
It after raw material is mixed in proportion, is heated through finished product machinery, dry high-speed kneading, then blow molding.By this implementation case
Plastic film is tested made from example, and weeding ether content is specifically shown in table 1.
Embodiment 2
It is prepared by a kind of degradable weeding plastic film, the raw material below degradable weeding plastic film by weight：
It after raw material is mixed in proportion, is heated through finished product machinery, dry high-speed kneading, then blow molding.By this implementation case
Plastic film is tested made from example, and weeding ether content is specifically shown in table 1.
Embodiment 3
It is prepared by a kind of degradable weeding plastic film, the raw material below degradable weeding plastic film by weight：
It after raw material is mixed in proportion, is heated through finished product machinery, dry high-speed kneading, then blow molding.By this implementation case
Plastic film is tested made from example, and weeding ether content is specifically shown in table 1.
Embodiment 4
It is prepared by a kind of degradable weeding plastic film, the raw material below degradable weeding plastic film by weight：
It after raw material is mixed in proportion, is heated through finished product machinery, dry high-speed kneading, then blow molding.By this implementation case
Plastic film is tested made from example, and weeding ether content is specifically shown in table 1.
Content (the mg/m of plastic film nitrofen in use prepared by 1 case study on implementation of table2)
The preparation method using plastic film provided by the invention, the plastics of preparation are can be seen that from upper table test result
The content of nitrofen is 40-100mg/m in mulch2, and after using 30-40 days, weeding ether content almost becomes zero in mulch.
Nitrofen is a kind of easy herbicide by adsorption by soil, is gradually reached by adsorption by soil during the use of plastic film
The effect of weeding.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
Claims (3)
1. a kind of degradable weeding plastic film, which is characterized in that a kind of raw material of degradable weeding plastic film is by weight
Amount part, which is counted, includes：
。
2. a kind of degradable weeding plastic film according to claim 1, which is characterized in that include the following steps：It will be former
Material mixes in proportion, is heated through finished product machinery, dry high-speed kneading, then blow molding.
3. a kind of degradable weeding plastic film according to claim 1 or 2, which is characterized in that the modeling of the preparation
Expect that the content of nitrofen in mulch is 40-100mg/m2, and using after 30-40 days, the content of nitrofen is zero in mulch.
