Description
Technical field
The present invention relates to technical field of polymer materials, more specifically, it relates to a kind of degradable bubble bags material and
Preparation method.
Background technique
With the accelerating rhythm of life, social life forward direction is convenient, hygienization develops.Bubble bags pack product continually
Into daily life.The appearance of these easy to use, cheap packaging materials brings all to people's lives
It is mostly convenient.But these packaging materials cause white pollution after use, form environmental hazard.Wherein, polyethylene conduct is most heavy
The plastic raw materials wanted, product are widely used in the fields such as bubble bags and other packaging materials.However it asks the pollution of environment
Topic also highlights therewith.Therefore polyethylene is modified so that it becomes degradable materials reduce the load generated to environment, tool
There is very major and immediate significance.
A kind of photodegradable plastics that degradation rate is high are disclosed in the Chinese invention patent of Publication No. CN106750711A
Material, the high photodegradable plastics material of shown degradation rate includes inner layer material and cladding material, and the cladding material is covered on institute
State inner layer material surface；The inner layer material includes following material component by weight: 7,042 72~77 parts of linear polyethylenes,
22~37 parts of 7042H linear polyethylene, 13~17 parts of 2426H low density polyethylene (LDPE), 22~27 parts of 401G metallocene, high transparency is anti-
5~8 parts of mist agent, 1~2 part of PE slipping agent, 5,301 23~28 parts of high density polyethylene (HDPE)s, 23~28 parts of 700F high density polyethylene (HDPE),
2~5 parts of P001 photodegradable aid；The cladding material includes following material component by weight: 7042 linear polyethylenes 48~
52 parts, 48~52 parts of 7042H linear polyethylene, 10~15 parts of 2426H low density polyethylene (LDPE).
Above-mentioned patent has problems in that: in the weaker area of illumination, the degree of degradation of photodegradable plastics is significant lower, and
It cannot achieve the effect that no pollution to the environment, on the other hand, when plastic material is discarded in field, as the time usually can be by other
Landfill makes it cannot get enough illumination, so as to cause the reduction of light degradation rate, if photodegradable plastics be made it is very thin again
The problems such as in the presence of the technological deficiency and weaker mechanical strength for being easily deformed tearing.
Summary of the invention
In view of the deficienciess of the prior art, the purpose of the present invention one is to provide a kind of degradable bubble bags material,
Has the advantages that not to be illuminated by the light influence, degradable.
The purpose of the present invention two is to provide a kind of preparation method of degradable bubble bags material, the bubble of this method preparation
Bag material has the advantages that not to be illuminated by the light influence, degradable.
To achieve the above object one, the present invention provides the following technical scheme that
A kind of degradable bubble bags material, the component including following parts by weight:
30-40 parts of low density polyethylene (LDPE)；
6-10 parts of glutelin；
4-6 parts of cellulose ether；
8-10 parts of lubricant；
1-3 parts of stearate.
It further preferably, further include 3-5 parts of starch-graft-acrylic acid resin.
Further preferably, any one of the stearate in zinc stearate, ferric stearate, calcium stearate.
Further preferably, the lubricant is oxidized polyethylene wax, paraffin, any one in polyethylene wax.
Further preferably, the cellulose ether is selected from hydroxypropyl methyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose
Any one in element.
It further preferably, further include 1-5 parts of hollow glass micropearl.
To achieve the above object two, the present invention provides the following technical scheme that
A kind of preparation method of degradable bubble bags material, comprising the following steps:
Low density polyethylene (LDPE), glutelin, cellulose ether, stearate are uniformly mixed by step 1, are warming up to 80-90 DEG C, are added
Lubricant is again stirring for being uniformly mixed, obtains mixture；
Step 2 melts the hopper of mixture investment double screw extruder, squeezes out, cooling, and pelletizing obtains degradable bubble
Bag material.
Further preferably, the extrusion temperature of the double screw extruder is 140-150 DEG C.
Compared with prior art, the invention has the following advantages:
(1) present invention has acid degradation, alkaline degradation, oxidative degradation, machinery by addition cellulose ether, the degradation mode of cellulose ether
Degradation, thermal degradation and photochemical degradating, can accelerate hydrolysis rate when illumination is weaker, be conducive to micro- after cellulose ether water absorption and swelling
Biological growth breeding, glutelin provides energy for microbial growth, stearate other than as lubricant, it includes
Metal ion can be used as cellulose ether degradation catalyst, metal ion can be with accelerating fibers element ether molecule chain break, pole
The degradability of polyethylene is improved greatly, so that the vinyon obtained can be good at degrading, the feature of environmental protection is good；
(2) since material of the invention is hygroscopic, mechanical performance and the service life of material be will affect, therefore, add wax class lubricant,
While wax class lubricant plays lubricating action when processing, hydrophobic layer is formed on the surface of the material, when material is discarded into field,
After hydrophobic layer is destroyed by extraneous factor, the starch-graft-acrylic acid resin with high-hydroscopicity absorbs rapidly extraneous water
Point, accelerate microbial growth, promotes the degradation of cellulose ether；
(3) for metal ion when catalytic cellulose ether is degraded, heating can significantly improve its degradation speed, and bubble bags material is out of office
When being absorbed heat outside by illumination or other factors, hollow glass micropearl can play the effect of heat preservation, accelerate the heat drop of cellulose ether
Solution, hollow glass micropearl can also improve the mechanical performance of bubble bags material.

Score) ethyl alcohol, distilled water flushing sample surfaces, then dried in 40 DEG C of vacuum drying ovens to constant weight, sample after record degradation
Quality m, sample degradation mass loss rate=[(m0-m)/m0] * 100%, the degrading quality loss late of each sample such as 2 institute of table
Show.
Test result and analysis: the degradation property test result of test specimen 1-18 and control sample 1-6 is as shown in table 2.
As shown in Table 2, the degradation rate after soil burial 45 days illustrates greatly test specimen 1-18 79.2% or more in the natural environment
Part natural degradation, bubble bags material degradation ability that the present invention is prepared under the microbial action of soil are strong；Test
Sample 1 and control sample 1-6 are individually compared it is found that being separately added into starch-graft-acrylic acid resin, glutelin, cellulose ether
After stearate, the degrading quality loss late of test specimen 1 is greatly improved；Compared with control sample 4, it is added at the same time stearic
When hydrochlorate and glutelin, the value added of the degrading quality loss late of test specimen 1 is greater than the sum of control sample 1 and 3, illustrates paddy egg
It is synergistic after white and stearate is added, significantly improve the degradation property of material.
The degradation property test result of table 2 test specimen 1-18 and control sample 1-6
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
For those of ordinary skill, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
