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, and the space of burying in the many more suburbs of the rubbish in city is obtained with regard to difficulty more.So increasing city is used the mode of incineration instead and is handled.
3, incinerate: the conventional plastic 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 of treatment process that changes the pollution mode.
The limitation with conventional treatment method of becoming increasingly conspicuous along with 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, POLYACTIC ACID, fats alcohol etc.; Because this type material can be degraded by microorganisms in soil, and the plastics of having filled this type material are improved in degraded in soil speed.But still there is deficiency in this type biodegradable plastic at present, shows that mainly the use of these packing materials has reduced the intensity of plastics, and to receive 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 received very big restriction.Doing comparison 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
To the deficiency that exists 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 biodegradable plastic, and degraded more easily.
Technical scheme of the present invention is achieved in that
A kind of biodegradable plastic is characterized in that: be in polyvinyl resin, to be dispersed with lignocellulose and zeolite powder, in the hole in the said 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 working 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;
(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:
Packing materials such as the starch of (1) using, POLYACTIC ACID, fats alcohol with lignocellulose replacement traditional biological degradative plastics; Because lignocellulose not only is easy to degraded; And as being usually used in being used to prevent coating cracking in concrete mortar, the plastering, improving water-retentivity, gaining in strength, strengthen material to the sticking power on surface; Snappiness and intensity are good, can improve the intensity of plastics.
(2) zeolite can adsorb biodegradable enzyme as porous mass, 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, helps the activation of cellulose degrading enzyme, and help cellulose degrading enzyme to lignocellulose and poly degraded; Zeolite itself is again a soil improvement agent simultaneously, can improve the soil.Cellulose degrading enzyme is adsorbed in the zeolite, can also plays a protective role, avoid in plastic working and use, being inactivated cellulose degrading enzyme.
(3) because this biodegradable plastic itself contains cellulose degrading enzyme; Therefore can activation in the edatope that is fit to; With lignocellulose degradation, no longer depend on the 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 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.
