Description
Technical field
The present invention relates to thin film fabrication techniques field, and in particular to a kind of biodegradable string powder-poly- second
Alkene film and preparation method thereof.
Background technology
The film that plastic sheeting is made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, is used for
Pack and as coating layer.Commercially shared share is increasing for plastics package and plastic packet product, particularly multiple
Plastic flexible package is closed, the fields such as food, medicine, chemical industry are had been widely used for, wherein again with packaging for foodstuff proportion most
Greatly, such as beverage packaging, quick-frozen food packaging, cooking food packaging, fast food packaging etc., these products all give people life
Bring great convenience.
Biodegradable plastic film refers under certain condition, can be completely biological in the case where that can secrete the microbial action of ferment
The high polymer material of degraded, can be divided into biological damage plastics and complete biodegradable plastics, wherein most promising be
Full-starch plastic film, this kind of plastic sheeting can be biodegradable completely after use, produced carbon dioxide and water, do not polluted ring
Border, is the Main way of recent domestic biodegradable starch-plasticses thin film study.And starch is due to being difficult to casting, product machine
The shortcomings of tool poor performance so that the purposes of starch is restricted.Therefore, starch is had to pass through after surface physics or chemical modification
Materials'use can be used as.
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 straw plastic film.
A kind of degradable straw plastic film, is made up of the following raw material：String powder, polyethylene, additive.
Described string powder is one kind in rice husk powder, stalk powder, corncob powder；It is using number
20-80 parts.
Described polyethylene is 20-80 parts using number.
Described additive and number on probation are 2 parts -5 parts of calcium sulfate, 1 part -3 parts of OPE, zinc stearate 1
- 2 parts of part, 0.5 part -2 parts of ethylene glycol, 0.5 part -3 parts of maleic anhydride.
A kind of preparation method of degradable straw plastic film comprises the following steps：
Step a：String powder is well mixed with remaining raw material in the ratio, and melting extrusion is carried out with double screw extruder
Granulation, obtains string powder-PE modified master batch；
Dual-screw-stem machine extrusion temperature is 100-180 DEG C, and screw speed is 100-400rpm.
Step b：String powder made from step a-PE modified master batch is added in inflation film manufacturing machine through heating, squeezed
Go out, be blow molded, it is upper traction, it is lower traction and winding film forming.
Inflation film manufacturing machine extrusion temperature is 100-200 DEG C, and screw speed is 100-450rpm.
The beneficial effects of the invention are as follows：A kind of degradable straw plastic film prepared by the present invention not only has good power
Performance is learned, also with excellent biodegradability, the use scope of product is wide, and a variety of plastic products of in the market can be made,
It is a kind of biodegradable plastic film with broad mass market prospect.Embodiment embodiment 1：35 parts of powder of straw, poly- second
