Biodegradable plastic film material bagDraw together synthetic material and natural macromolecular material, due to natural macromolecular material aboundresources and renewable, because ofThis is especially noticeable. But on organosilicon strand, contain great amount of hydroxy group, easily in strand and pointSubchain forms hydrogen bond outward, therefore indissoluble, infusibility, and poor water resistance, and a chance water or long-term storage are at tideIn humid air, easily absorb moisture, affect its stability.
Have much with the research of organosilicon-polyvinyl alcohol fully biodegradable plastic sheeting at presentReport, but wherein prepared organosilicon-polyvinyl alcohol degradative plastics still exist degradation speed slowly,The problem such as the compatible blend of organosilicon 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, to ringOrganosilicon-polyvinyl alcohol double degradation plastic film formula of border close friend and preparation method thereof.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of organosilicon-polyvinyl alcohol double degradation plastic film, is characterized in that, by following mass fractionRaw material is made: epoxy resin 60-70 part, amine curing agent 20-25 part, expoxy propane diluent 50-70 part,Active in tassement polaire 60-70 part, phenol aldehyde modified ethylenediamine 20-30 part, polyvinyl alcohol 60-70 part, Artemisia Glue15-20 part, hydroxypropyl cellulose 12-18 part, pulullan polysaccharide 7-15 part, nano silicon 13-16Part, zinc stearate 15-20 part, OPE 14-18 part, ethyl silicon oil 12-17 part, calcium carbonate13-15 part, glutaraldehyde 4-10 part, 18 alcohol 13-15 parts.
The particle diameter of described nano silicon is 20-100nm.
A preparation method for organosilicon-polyvinyl alcohol double degradation plastic film, is characterized in that, comprise asLower step:
Step a: by epoxy resin, amine curing agent, expoxy propane diluent, active mixed without tassement polaire heatRefining, mixing temperature is 120 DEG C, 24 hours time, then further stirs with phenol aldehyde modified ethylenediamineMaking beating, obtains hot glue;
Step b: first by the OPE of hot glue and carboxy-propyl cellulose, glutaraldehyde, 1/3-1/2 andThe polyvinyl alcohol of 1/4-1/3 is put into baking oven dries, then through double screw extruder extrude, after water-cooled, cuttingMake biodegradable master batch;
Step c: first by Artemisia Glue, pulullan polysaccharide, nano silicon, zinc stearate, 18 alcohol andThe polyvinyl alcohol of 1/4-1/3 mixes evenly, then extrudes, makes light after water-cooled, cutting through double screw extruderDegradable master batch;
Steps d: to add in the biodegradable master batch making and light degradation masterbatch ethyl silicon oil, calcium carbonate,Remaining OPE and polyvinyl alcohol, then use through double screw extruder extrude, water-cooled, cuttingAfter make mother raw material degradable, obtain aimed thin film goods finally by inflation film manufacturing machine blown film.
The invention has the beneficial effects as follows: the plastic sheeting that the present invention makes has the biological and dual degraded work of lightWith, can effectively solve the white pollution problems that common plastic film difficult degradation brings, and production technologySimply, cost is low, is conducive to suitability for industrialized production.
