Abstract
The present invention relates to a nontoxic and innoxious biological completely degradable additive agent and a biological completely degradable plastic product thereof, which belongs to the field of biochemistry. The components of the biological completely degradable additive agent are formed by mixing polyhydroxy butyrate ester, organic nitrogenous material, alcohol and cellulose material according to certain proportion, and the additive agent and organic high molecular compounds are used as base materials to be mixed, stirred, pulped, heated, extruded and formed to be manufactured into the completely degradable plastic product. The product has the advantages of high quality of, low cost and complete degradation; furthermore, the present invention provides high and new technology for thoroughly treating the white pollution, waste of the present invention is innocuous and can be recovered to be used as feed and fertilizer, and the positive cycle of physical resources can be formed. The implementation of the present invention can positively promote the rural economic development and brings the important breakthrough for producing raw materials at the packing industry.
Description
The invention belongs to biochemical field, relate to high-fall additive and the complete degradable plastic goods thereof separated of a kind of nontoxic pure plant.
In recent years, especially domestic both at home and abroad to researching and solving trade waste---" white pollution " that plastic packing product caused caused the great attention of the parties concerned, and how hundred-percent degraded these " white garbages " thoroughly solves " white pollution " becomes the hot subject of attracting attention in the world.The present state of the art is to adopt method and PE or the PS blend production that adds starch and photosensitizers mostly, in the petroleum chemistry plastics, mix natural degradable macromole such as starch etc., though can shorten the plastic degradation cycle, but the product after cracked still can not or still need degraded for a long time, increase the difficulty that reclaims again, caused secondary pollution; Secondly this kind product exceeds more than 30% than conventional plastic products production cost, is difficult to promote; At present a kind of paper product container of the natural cellulose material produce with Wholly-degradable comes out, but because of its waterproof, grease proofing, gas barrier properties is poor, intensity is low, cost is high, be that its market value of example is three times of conventional plastic lunch box only with fast food lunch-box made of paper, and the needs of some performance incompatibility modern packaging, so range of application is very little.From environmental angle, modern science thinks that production of paper products is several times or tens times of plastics to water and atmospheric pollution.Up to the present, domestic still do not have mature technology that can absolutely degrade, the low price plastic packing product to come out.
The present invention is directed to above problem, provide a kind of and can high-fallly separate additive, itself and base-material are mixed and made into the biological whole degradation plastic goods that can absolutely degrade.
Technical scheme of the present invention is: with organic high molecular compound (starch) is base-material, fills can high-fallly to separate additive in right amount, make can absolutely degrade, nontoxic, harmless plastics:
Can high-fallly separate the composition proportion following (weight %) of additive:
Poly butyric ester 10～50 urea 10～60
Alcohols 5～30 cellulose families 5～20
But with can high-fallly separating the complete degradable plastic goods that additive is made, its proportioning components following (weight %):
Can high-fallly separate additive 15～25
Starch 75～85
The weight percent of additive be can high-fallly separate more than adjusting, but foaming kind, hard class, soft class complete degradable plastic goods made.
Its technical process is as follows: with a certain proportion ofly can high-fallly separate additive and add in a certain proportion of organic high molecular compound (starch) → thorough mixing → stirring pulping → heating → extrusion molding (blow molding) → die sinking extracts goods.
The present invention has the potentiality and the application value of tangible Sustainable development, and social benefit and economic benefit are very considerable.
Be embodied in:
(1) its goods abandon the absolutely degraded of eight weeks of back, preserve the ecological environment for thoroughly administering " white pollution ", and new and high technology is provided;
(2) its goods matter height, valency are low, and being example with the cutlery box reduces by 50% than the cost of existing paper table ware, and paper table ware is subjected to limiting output of imported raw material to be difficult to increase substantially, and cost is difficult to reduce;
(3) the waste toxicological harmless of its goods, still capable of using as feed, fertilizer after the recovery, and then the benign cycle of formation physical resources;
(4) if a large amount of organic high molecular compounds of adopting of enforcement of the present invention will obviously enlarge the market flow of industrial starch based on starch based, promote development of rural economy;
(5) the present invention is the important breakthrough of packaging industry raw materials for production, and lecture promotes and drive the development of wrapping mechanism industry in a sense.
Embodiment:
1, can high-fallly separate the composition proportion following (weight kg) of additive:
Poly butyric ester 50 urea 60
Ethylene glycol 20 Mierocrystalline celluloses 15
Above composition uniform mixing.
But the proportioning components of 2 complete degradable plastic cutlery boxs following (weight kg):
Starch 80 poly butyric esters 3 urea 10
Ethylene glycol 2 Mierocrystalline celluloses 5
3, technical process is as follows: with above composition thorough mixing → stirring pulping → foamable
→ inject mould → extrusion molding → die sinking to extract goods.
If the production membrane product, the front operation is identical, just the extrusion blow moulding of heating back.
Claims (3)
1, a kind ofly can high-fallly separate additive, (weight %) is as follows for its composition proportion:
Poly butyric ester 10～50 urea 10～60
Alcohols 5～30 cellulose families 5～20
But 2, a kind ofly can high-fallly separate the complete degradable plastic goods that additive is made with claim 1 is described, (weight %) is as follows for its proportioning components:
Can high-fallly separate additive 15～25
Starch 75～85
But 3, a kind of complete degradable plastic goods according to claim 2, the weight percent of additive can be high-fallly separated in adjustment, makes foaming kind, hard class, soft class plastics.
