Abstract
The invention discloses a biodegradable plastic. The biodegradable plastic is characterized in that lignocelluloses and zeolite powder are scattered in polyethylene resin, and cellulose degradation enzymes are arranged in pores of the polyethylene resin. The biodegradable plastic is prepared by steps: adding biodegradable enzymes into ethanol and stirring; mixing the zeolite powder with ethanol solution at the step one, and removing the ethanol; mixing the lignocelluloses, the polyethylene resin and the zeolite powder; and using a granulator for granulating. Compared with starch type biodegradable plastics, the biodegradable plastic has the advantages of high strength and easiness in degradation.
Description
Technical field
The present invention relates to field of new, relate in particular to a kind of biodegradable plastic.
Background technology
Along with the development of petrochemical industry technology, plastics and goods thereof occupy more and more important position in people's life.Yet plastics are when promoting the well-being of mankind, and a large amount of manufacturings and use along with plastics have also brought new trouble to the people, and distinct issues are " white pollutions ", and reason is that plastics are difficult to decompose in physical environment.
The treatment process of conventional plastic waste products has:
1, recycling: this is optimal treatment process, but can't accomplish very recovery and utilization, otherwise does not just have " white pollution ".
2, bury: the high molecule plastic waste products be difficult for to decompose, and occupies a large amount of spaces of burying, the more many suburbs of the rubbish in city bury the space with regard to difficult obtaining more.So the mode that incineration is used in increasing city instead is handled.
3, incinerate: traditional plastics waste products, over-emitting black exhaust during burning, polluted air produces toxic gases such as hydrogenchloride, formaldehyde, polychlorobiphenyl, incomplete combustion, residual black sticking shape colloid is attached at the incinerator furnace wall, intercepts thermal conduction, influences incinerator work-ing life.In fact incinerating is a kind for the treatment of process that changes the pollution mode.
Along with becoming increasingly conspicuous and the limitation of conventional treatment method of white pollution problems, people's degradative plastics that begins one's study, wherein a kind of preparation method of biodegradable plastic is filled in the plastics with the material that can degrade such as starch, poly(lactic acid), fats alcohol etc., because this class material can be degraded by microorganisms in soil, and the plastics of having filled this class material are improved in degraded in soil speed.But still there is deficiency in this class biodegradable plastic at present, shows that mainly the use of these packing materials has reduced the intensity of plastics, and to be subjected in the edatope influence of microbe species and quantity bigger for degradation speed in addition, and degradation speed is still slower.Therefore, the application of this degradative plastics has been subjected to very big restriction.Comparing with the simplest plastics bag, through the effort over 50 years, still still is the world of conventional plastic bag on the market now.
Summary of the invention
At the deficiencies in the prior art, the object of the present invention is to provide a kind of new bio degradative plastics, this biodegradable plastic is than the strong Gao Yaogao of traditional filled-type biodegradable plastic, and easier degraded.
Technical scheme of the present invention is achieved in that
A kind of biodegradable plastic is characterized in that: be to be dispersed with lignocellulose and zeolite powder in polyvinyl resin, in the hole in the described zeolite powder cellulose degrading enzyme arranged.
The weight content of polyvinyl resin described in the plastics, lignocellulose, cellulose degrading enzyme and zeolite powder is respectively
The present invention also provides the production method of above-mentioned biodegradable plastic, it is characterized in that comprising successively following process:
(1) cellulose degrading enzyme is added in the ethanol stirs evenly;
(2) zeolite powder is mixed with ethanolic soln in the step (1), slough ethanol again;
(3) lignocellulose, polyvinyl resin, zeolite powder are mixed, pass through the tablets press granulation then.
Beneficial effect of the present invention is:
(1) packing materials such as the starch of using with lignocellulose replacement traditional biological degradative plastics, poly(lactic acid), fats alcohol, because lignocellulose not only is easy to degraded, and as being usually used in being used for preventing coating cracking in concrete mortar, the plastering, improving water-retentivity, gaining in strength, strengthen the material to the sticking power on surface, snappiness and intensity are good, can improve the intensity of plastics.
(2) zeolite is as porous mass, can adsorb biodegradable enzyme, can also improve the wear resistance of plastics as filler, its very strong water absorbing properties of while, zeolite can adsorb the moisture content thing degrading enzyme of making a living in soil provide moist environment, is conducive to the activation of cellulose degrading enzyme, and is conducive to cellulose degrading enzyme to lignocellulose and poly degraded, zeolite itself is again soil improvement agent simultaneously, can improve the soil.Cellulose degrading enzyme is adsorbed in the zeolite, can also plays a protective role to cellulose degrading enzyme, avoid in plastic working and use, being inactivated.
(3) because this biodegradable plastic itself contains cellulose degrading enzyme, therefore in the edatope that is fit to, can activate, with lignocellulose degradation, no longer depend on kind and the quantity of related microorganisms in the soil, guaranteed effective, the degraded in time of this biodegradable plastic.
(4) preparation method is simple, and cellulose degrading enzyme adds to stir evenly in the ethanol again zeolite powder is mixed with ethanolic soln, sloughs ethanol again, makes cellulose degrading enzyme be filled into the micropore inside of zeolite dexterously, has avoided following process process deactivation cellulose degrading enzyme.
