Abstract
The invention discloses the master batch of a kind of photodegradable plastics particle, including following material: polyethylene, photodegradable aid, light stabilizer, lubricant.Compared with prior art, the mechanical property of the plastic film for agricultural use prepared by master batch presses GB 4,455 2006 standard detection to the present invention, its hot strength vertical, horizontal >=14MPa, elongation at break vertical, horizontal >=300%, angle tear strength vertical, horizontal >=55KN/m.The light transmission of this film is good, and Cotton Gossypii plays a part volume increase, and after the induction period of 60 days, the degradative phase of 150 days, its thin film relic is less than 4 × 4cm2。
Description
Technical field
The invention belongs to a kind of degradable plastic masterbatch, particularly belong to the photodegradable plastics master batch containing polyethylene.
Background technology
Agricultural mulching can play soil moisture conservation, insulation, weeding, parasite killing four kinds effect, can increase substantially the yield of crops.
The master batch of tradition agricultural mulching is polyethylene, and this material has the physical property of excellence.But the degradation time of this plastic sheeting
Long, it is widely used and can cause serious " white pollution ".The main path solving plastic sheeting " white pollution " at present is exploitation
Degradable agricultural film, current degradable agricultural film, its light transmission is poor, causes the underproduction of Cotton Gossypii, and through the induction period of 60 days,
The degradative phase of 150 days, its relic is more than 4 × 4cm2, it is impossible to meet actual needs.
Summary of the invention:
The technical problem to be solved is to provide a kind of induction period through 60 days, after the degradative phase of 150 days, its
Relic is less than 4 × 4cm2Plastic master batch.
The present invention solves the technical scheme of technical problem: the master batch of a kind of photodegradable plastics particle, including following thing
Matter and weight portion:
Described photodegradable aid is ferric dialky dithiocarbamatc.
Described light stabilizer is 3-ketone-4-azepine-5a-androstane-17b-carboxylic acid.
Described lubricant is zinc stearate；
Described polyethylene includes that the line style of high density polyethylene (HDPE) that concentration expressed in percentage by weight is 60-75% and 25-40% is low
Density polyethylene；
After utilizing prior art to carry out blending extrusion polyethylene, photodegradable aid, light stabilizer, lubricant, make master batch.
The present invention, by selecting specific light stabilizer, makes the thin film made keep original power in the induction period of 60 days
Learn performance, and in the degradative phase of 150 days, strengthen the degradation capability of ferric dialky dithiocarbamatc, finally make thin film residual
Sheet is less than 4 × 4cm2。
The present invention is compared with present technology, and the mechanical property of the plastic film for agricultural use prepared by master batch presses the inspection of GB4455-2006 standard
Survey, its hot strength vertical, horizontal >=14MPa, elongation at break vertical, horizontal >=300%, angle tear strength vertical, horizontal >=
55KN/m.The light transmission of this film is good, and Cotton Gossypii plays a part volume increase, and through the induction period of 60 days, the degradative phase of 150 days
After, its thin film relic is less than 4 × 4cm2。
Detailed description of the invention
Below by embodiment, the present invention is specifically described, it is necessary to it is pointed out here that be that following example are served only for
The present invention is further described, it is impossible to be interpreted as limiting the scope of the invention, the person skilled in the art in this field
According to the invention described above content, the present invention is made some nonessential improvement and adjustment, still fall within scope.

Ethylene；
Embodiment 4:
In addition to being not added with photodegradable aid, light stabilizer, remaining is same as in Example 1.
Embodiment 5:
In addition to being not added with light stabilizer, remaining is same as in Example 1.
By the master batch made by embodiment 1,2,3,4,5, by prior art, being blow molded into plastic film for agricultural use, its mechanical property is pressed
GB 4455-2006 standard detection, its hot strength vertical, horizontal >=14MPa, elongation at break vertical, horizontal >=300%, right angle tears
Resistance to spalling vertical, horizontal >=55KN/m.
By the blown plastic film for agricultural use of embodiment 1,2,3,4,5, cover on the cotton field in Xinjiang, the Cotton Gossypii of embodiment 1,2,3
The high 8-10% of Yield compari@embodiment 4, the output of cotton of embodiment 5 is lower than embodiment 4 by 7%.Through the induction periods of 60 days and 150
