Abstract
The present invention relates to a kind of degradable stalk polyethylene film and preparation method thereof, mainly solve existing general-purpose plastics and be also easy to produce plastic garbage, pollution environment and the expensive shortcoming of existing biodegradable plastic.It is characterized in that using plant fiber powder, polyethylene and auxiliary agent etc..Production method is after mixing above-mentioned plant fiber powder, polyethylene and the agitated machine of other auxiliary agents, to be added in double screw extruder, through carrying out mixing plasticizing granulation in double screw extruder, then by being blow-moulded into film.Product of the present invention is nontoxic, available for Phthalates in agricultural film, packaging for foodstuff, daily life etc..This product can be degraded in natural environment by microbial portion, overcome problem of environmental pollution caused by existing general-purpose plastics rubbish.
Description
Technical field
The present invention relates to thin film fabrication techniques field, and in particular to a kind of biodegradable plant fiber powder-polyethylene
Film and preparation method thereof.
Background technology
Existing plastic products, due to economical and practical, easy to process, using quite varied but traditional commodity polymer material
Material is difficult for Institute of Micro-biology's degraded due to itself property, i.e., imputrescibility goes mouldy, and then causes to reside in existing life for a long time
Among living.Therefore, plastic garbage bag pollution becoming serious, causes the concern of whole world popularity.
It is existing can not be Institute of Micro-biology degraded commodity polymer material in add it is a certain proportion of, can be microorganism
The natural fiber material degraded, such as powdered rice hulls, powder of straw, maize cob meal and wheat flour, obtained product just can portion
Divide and degraded by Institute of Micro-biology.Alleviate the problem of environmental pollution that all-plastic film article is brought.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of technique is simple, production cost is low and environment amenable
Degradable polyethylene film.
A kind of degradable polyethylene film, is made up of the following raw material：Plant fiber powder, polyethylene, auxiliary agent.
Described plant fiber powder is one kind in powdered rice hulls, powder of straw, maize cob meal and wheat flour；It is using number
20-30 parts.
Described polyethylene is 60-70 parts using number.
Described additive and use number is 1 part -3 parts of wood moulding coupling agent, 1 part -2 parts of calcium stearate, maleic anhydride 4
Part -5 parts, 2-3 parts of white oil.
A kind of preparation method of degradable polyethylene film comprises the following steps:
1 string powder is well mixed with remaining raw material in the ratio, and carrying out melting extrusion with double screw extruder makes
Grain, obtains plant fiber powder-PE modified master batch；
Dual-screw-stem machine extrusion temperature is 100-220 DEG C, and screw speed is 60-600rpm.
2 by plant fiber powder made from 1-PE modified master batch be added in inflation film manufacturing machine through heating, extrusion, blowing, on lead
Draw, it is lower traction and winding film forming.
