Abstract
The invention discloses a multi-degradable plastic film which comprises the following components in percentage by weight: 85-98.7% of a polymer substrate, 0.1-1% of nano-titanium dioxide, 0.1-1% of kaolin, 0.1-1% of ferric stearate and 1-2% of hydrophilic resin. A preparation method of the multi-degradable plastic film comprises the following steps: uniformly mixing polyolefin, nano-titanium dioxide, kaolin, ferric stearate and hydrophilic resin in percentage by mass, melting and pelleting, and performing blow molding by using a blow molding machine, thereby preparing the multi-degradable plastic film. The multi-degradable plastic film has the beneficial effects that firstly, the use property of a product is not affected, and the basic requirements of daily life, agriculture use and the like can be met; secondly, multi-degradation can be achieved by using light, heat and biological substances, and due to the added hydrophilic resin, the plastic film can easily absorb the moisture in the air and the soil, multi-degradation is accelerated, and complete degradation is achieved.
Description
Technical field
The present invention relates to a kind of degredation plastic film, particularly relate to a kind of can the plastics film and preparation method thereof of multiple degrading.
Background technology
The life of the people easy to use of plastics, but bring environmental pollution more.In recent years in order to reduce the white pollution that plastics bring, the research and development of degradable plastics and use become more and more important.Common degradable plastics poly(lactic acid) (PLA), poly butylene succinate (PBS), polycaprolactone (PCL), polyvinyl alcohol (PVA), poly-beta-hydroxy-butyrate (PHB), PHA (PHA), carbon dioxide copolymer, aliphatic aromatic multipolymer etc.Although volume reduces to economize the land resource, need not burn after the degraded of degradable plastics tool, reduce the advantages such as noxious gas emission, still there is the shortcoming such as high expensive, physical and mechanical property difference in degradable plastics, have impact on its range of application.Chinese patent " full starch-type biodegradable plastic " (200310111110.7), " full degradable additive and full degradable plastic products " (98114170.6) etc. report by the biodegradable plastic of the materials processing of the readily biodegradable such as starch, Mierocrystalline cellulose, although this kind of plastics can by complete biodegradable, mostly have that production technology content is high, expensive, bad mechanical strength and heat-resisting a, shortcoming such as water tolerance is weak.Chinese patent " controllable light/biodegradation plastic material " (200910023271.8), " preparation method of photodegradation nano TiO 2-polyethylene composite plastic " (200410060618.3) etc. report the photodegradable plastics that can issue third contact of a total solar or lunar eclipse oxidative degradation at sunlight or UV-irradiation, this kind of plastics only have the initial stage after discarding to expose in the sun under normal circumstances, along with the continuous accumulation of rubbish, gradually by other article landfill, thus lose photodegradation chance, but, along with the accumulation of rubbish is by landfill compost gradually, produce heat, the heat utilizing garbage compost to produce can carry out thermal-oxidative degradation.The plastics film with multiple degrading ability can better be degradable by the light in environment, heat, microorganism, reaches real environmental friendliness.
Summary of the invention
The object of this invention is to provide a kind of can the plastics film and preparation method thereof of multiple degrading.
The present invention is by the following technical solutions: a kind of can the plastics film of multiple degrading, the weight percent of its each component is: polymeric substrate 85 ~ 98.7%, nano titanium oxide 0.1 ~ 1%, kaolin 0.1 ~ 1%, iron stearate 0.1 ~ 1%, hydrophilic resin 1 ~ 2%.
One or more in the polyolefine such as described polymeric substrate Low Density Polyethylene (LDPE), linear low density polyethylene (LLDPE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), molecular weight is 10K ~ 60K.
Described hydrophilic modifying agent is one or more in the hydrophilic polymers such as polyoxyethylene glycol (PEG), polyoxyethylene (PEO), polyvinyl alcohol (PVA), and molecular weight is 4K ~ 500K.
Of the present invention a kind of can the preparation method of plastics film of multiple degrading, carry out according to technique below:
By above-mentioned quality of material per-cent, polyolefine, nano titanium oxide, kaolin, iron stearate, hydrophilic resin are mixed in proportion, melt pelletization; Through blow moulding machine blow molding, the degradable plastic film of system.
Beneficial effect of the present invention is: 1) one of the present invention can be formed primarily of polyolefine by multiple degrading plastics film, and the use properties of product is not affected, and can meet the basic demand such as daily life and agricultural use; 2) add nano titanium oxide to degrade under solar radiation, simultaneously, kaolin is as natural microbiological culture media, more microorganisms can be assembled, make plastics film generation biological degradation, the interpolation of iron stearate can promote the DeR of plastics film under heat effect, and the interpolation of hydrophilic resin makes this plastics film more easily can absorb moisture in air soil, the generation of accelerating multiple degraded, thus reach degradable.
