Abstract
The invention relates to a degradable plastic masterbatch and a preparation method thereof. The method comprises the following steps: polyolefin resin, starch, polyethylene wax, and zinc stearate, mixing the above materials, and performing extrusion cutting on a mixture to obtain the plastic masterbatch. The plastic masterbatch has the advantages that the plastic masterbatch has low burning point, after combustion, the residue forms carbonized powder, black smoke and toxic gas cannot be generated during a combustion process, and after being buried, the plastic masterbatch is subjected to automatic decomposition. The plastic masterbatch has the advantages that appearance is colorless and odorless, the plastic masterbatch has good intermiscibility, and is a good environmental-protection material.
Description
Technical field
The present invention relates to Phthalates field, particularly relate to a kind of degradation plastic masterbatch and manufacture method.
Background technology
Contemporary society, scientific and technological level is the most flourishing, social life forward judicial convenience, high-speeding development.In order to comply with public demand, disposable foam plastics lunch box, tableware, plastic bag etc. start to frequently enter daily life.
Current widely used Phthalates is photolysis plastic, and therefore, photodegradable plastics goods (such as bury native part, field filled by rubbish) photosensitizer under no light condition cannot induce degraded or because photosensitizer is by shortcomings such as high implant parcel make degradation effect poor.
Summary of the invention
For the problems of the prior art and defect, the present invention provides a kind of degradation plastic masterbatch and manufacture method.
A kind of degradation plastic masterbatch and manufacture method that the present invention provides have employed following technical scheme:
A kind of degradation plastic masterbatch, according to suitably very than mixing granule including vistanex, starch, Tissuemat E, zinc stearate etc..
Preferably, in above-mentioned degradation plastic masterbatch, vistanex is polyisobutylene.
Preferably, in above-mentioned degradation plastic masterbatch, starch is Semen Maydis composite powder.
Preferably, the present invention provides the manufacture method of a kind of degradation plastic masterbatch, including:
Step one: vistanex, starch, Tissuemat E, zinc stearate are respectively respectively put into high-speed mixer mixture according to appropriate percentage ratio.
Step 2: function mixing material good for mixture is put into equidirectional parallel double-screw extruder, and heated, extruding cuts into degradation plastic masterbatch.
The invention has the beneficial effects as follows that burning-point is low, after burning, residue is formed in carbonization powdery, combustion process and will not produce black smoke and toxic gas, and can the advantage of automatic classifying after burying.

Fig. 1 show degradation plastic masterbatch manufacturing process block chart of the present invention.
Label declaration:
1, vistanex；2, starch；3, Tissuemat E；4, zinc stearate；5, degradation plastic masterbatch.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, but is not intended as the foundation limiting the present invention.
Fig. 1 is a kind of degradation plastic masterbatch manufacturing process block chart.Degradable plastics mother material of the present invention, mainly comprises: vistanex 1, starch 2, zinc stearate 3, Tissuemat E 4, and heated, extruding cutting forms.
Concrete, the constituent vistanex 1 of described degradable masterbatch is polyisobutylene.
Further, the constituent starch of described degradable masterbatch is Semen Maydis composite powder.
Further, in the manufacture method of a kind of degradation plastic masterbatch of the explanation present invention, its work flow is as described below:
Step one: first the zinc stearate 4 of the Tissuemat E 3,1% ~ 5% of the starch 2,5% ~ 10% of vistanex 1,34% ~ 50% that percentage by weight is 35% ~ 53% is respectively put into high-speed mixer mixture, setting high-speed mixer rotating speed is optimal between 845 ~ 1100 circle/point (r/min).
Step 2: function mixing material good for above-mentioned mixture being put into equidirectional parallel double-screw extruder group, is heated between 150 ~ 165 degrees Celsius, extruding cuts into degradation plastic masterbatch.Wherein, it is optimal between particle diameter 1 ~ 2 millimeter (mm), length 1 ~ 4 millimeter (mm).This degradation plastic masterbatch has that burning-point is low, environmental protection, colorless and odorless, and degradable advantage.
Being described in detail embodiment provided by the present invention above, principle and the embodiment of the present invention are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method and the core concept thereof of the present invention.It should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to the present invention is carried out some improvement and modification, these improve and modify in the protection domain also falling into the claims in the present invention.
