Description
Technical field:
The present invention relates to thin film fabrication techniques field, be specifically related to a kind of Starch-Polyvinyl Alcohol double degradation plastic film.
Background technology:
Pollution environment being brought in order to solve the plastic membrane products such as packing bag, refuse bag, investigator is being devoted to develop the plastics film of environmentally safe always both at home and abroad.Biodegradable plastic film material comprises synthetic materials and natural macromolecular material, due to natural macromolecular material aboundresources and renewable, therefore especially noticeable.Yet on starch molecular chain, contain great amount of hydroxy group, easily in molecular chain and molecular chain form hydrogen bond outward, so indissoluble, infusibility, and poor water resistance, one meets water or long-term storage easily absorbs moisture in damp atmosphere, affects its stability.
The at present research with Starch-Polyvinyl Alcohol class fully biodegradable plastics film has had a lot of reports, but wherein prepared Starch-Polyvinyl Alcohol class degradative plastics still exist degradation speed slowly, the problem such as the compatible blend of starch and polyvinyl alcohol based polymer is bad.
Summary of the invention:
Technical problem to be solved by this invention is to provide that a kind of production cost is low, technique is simple, environment amenable Starch-Polyvinyl Alcohol double degradation plastic film.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A Starch-Polyvinyl Alcohol double degradation plastic film, by the raw material of following mass fraction, made:

Described starch is a kind of in W-Gum, wheat starch, oat starch, barley starch, tapioca (flour), yam starch, buckwheat starch and bean powder.
The particle diameter of described nano silicon is 20-100nm.
A preparation method for Starch-Polyvinyl Alcohol double degradation plastic film, comprises the steps:
Step a: first the polyvinyl alcohol of the oxidized polyethlene wax of starch, carboxy-propyl cellulose, glutaraldehyde, 1/3-1/2 and 1/4-1/3 is put into baking oven and dry, then extrude, make biodegradable master batch after water-cooled, cutting through twin screw extruder;
Step b: first the polyvinyl alcohol of artemisia glue, pulullan polysaccharide, nano silicon, Zinic stearas, stearyl alcohol and 1/4-1/3 is mixed evenly, then extrude, make photodegradation masterbatch after water-cooled, cutting through twin screw extruder;
Step c: add ethyl silicon oil, calcium carbonate, remaining oxidized polyethlene wax and polyvinyl alcohol in the biodegradable master batch making and photodegradation masterbatch, then use through twin screw extruder and extrude, make mother raw material degradable after water-cooled, cutting, finally by inflation film manufacturing machine blown film, obtain aimed thin film goods.
The invention has the beneficial effects as follows: the plastics film that the present invention makes has biological and the dual Degradation of light, can effectively solve the white pollution problems that common plastic film difficult degradation brings, and production technique is simple, cost is low, is conducive to suitability for industrialized production.
