Abstract
The invention discloses an environment-friendly type green plastic bag product, comprising the following components by weight: 25-60% of film-grade polyethylene, 10-55% of film-grade polylactic acid, 4-15% of filler, a proper amount of additive, and 4-25% of reclaimed same-property waste regeneration plastic particle. The environment-friendly type plastic bag of the invention can automatically be decomposed above 55 DEG C or under the action of oxygen-rich microbe, and the waste plastic bag can automatically be degraded in the environment to finally generate carbon dioxide and water. The plastic bag of the invention has the advantages of simple formula, easy preparation, less technology steps, short flow and small equipment investment.
Description
Technical field
The present invention relates to a kind of plastics film, particularly a kind of environment-friendly plastics bag goods.
Background technology
As everyone knows, the plastics bag of making of plastics film is light, thin, waterproof, intensity is large, cost is low, a kind of good wrapping material, the use of plastics bag brings great convenience to people's life, make the consumption of plastics bag increasing, be difficult for reclaiming, being difficult for degraded with waste plastic bag later, a large amount of waste plastic bags has become a serious problem of current contaminate environment.In order to alleviate plastics film to the pollution of environment, people have developed some environment-friendly degradable plastic films, as: the patent No.: 200710144500.2, paper-simulating degradable plastic film and manufacture craft thereof; And the patent No.: 201110051187.4, the method for fully biodegradable Plastic Resin and film based article thereof.This class degradable plastic film, its moiety has the film-grade plastics and can cause the component that plastics produce degraded, such as starch, calcium carbonate etc., this degradable plastic film is the addition type degradable plastic film, and the addition type degradable plastic film is to improve environment to have brought into play certain active effect.But processing performance plastics film the physical property of product and the outward appearance bad, that make of this degradable plastic film processing are relatively poor.
In addition, the degraded of this degradable plastic film needs certain rigid condition, and the environment of plastics film after discarded, done in the refuse disposal system of sealing, be exactly to be exposed in the unfixed physical environment of condition, very difficult guarantor levies the needed rigid condition of this degradation of plastic film, and no matter these degradative plasticss are can not degrade well because being subjected to condition restriction in refuse disposal system or at physical environment in most of the cases.In the prior art, do not have can the environment after discarded in, guarantee the degradable plastic film of degraded.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, propose to guarantee the Degradable environment protection green plastic bag product of degraded in a kind of environment after discarded.
The objective of the invention is to be achieved through the following technical solutions:
The environment-friendly plastics bag, its moiety has film-grade polyethylene and weighting material, it is characterized in that: its moiety also has film-grade poly(lactic acid) and waste and old recycled plastic granules, and its raw material and weight proportion are:
Film-grade polyethylene 25% 60%, film-grade poly(lactic acid) 10% 45%, weighting agent 4%-15%, waste and old recycled plastic granules 4%-25%
Poly(lactic acid) (PLA) is a kind of novel biodegradable material, and the starch material that uses reproducible plant resources (such as corn) to propose is made.Starch material is made lactic acid via fermenting process, converts poly(lactic acid) to by chemosynthesis again.It has good biodegradability, can be degradable by the occurring in nature microorganism after the use, finally generate carbonic acid gas and water, and free from environmental pollution, this is highly beneficial to protection of the environment, is the environment-friendly material of generally acknowledging.Poly(lactic acid) (PLA) has the best tensile strength and extensibility, poly(lactic acid) also can various common process modes be produced, for example: the fusing extrusion moulding, ejection formation, blowfilm shaping, foaming and vacuum forming have similar molding condition with present extensive employed polymkeric substance, and it also has the printing performance identical with conventional films in addition.Polylactic acid film also has good ventilation property, oxygen-permeable and saturating dioxy two carbon, and it also has the characteristic of isolation smell.When incinerating poly(lactic acid) (PLA), its combustion heat value is identical with the incineration stationery, be half of incineration conventional plastic (such as polyethylene), and the incineration poly(lactic acid) can never discharge the toxic gases such as nitride, sulfide.Human body also contains the lactic acid that exists with morphon, and this has just represented the security that this decomposability product has.Polylactic acid film is stable performance at normal temperatures, is higher than 55 ℃ or can automatic classifying under the effect of oxygen enrichment and microorganism in envrionment temperature.Poly(lactic acid) is desirable complete-degradable plastic, can be made into the green plastic of the Degradable environment protection with different degradation speeds with film-grade poly(lactic acid) and the blend of film-grade vinyon.
The present invention can be with common plastic film blowing machine production, after can mixing film-grade polyethylene, film-grade poly(lactic acid), weighting agent, waste and old recycled plastic granules by a certain percentage during production, the adding plastic film blowing machine is warmed up to specified temperature can produce the special-purpose cylindrical membrane of environment-friendly plastics bag.
Environment-friendly plastics bag goods disclosed in this invention prescription is characterized in: 1, added the effect that the film-grade medium-density polyethylene has played reinforced plastics bag intensity; 2, added the film-grade poly(lactic acid), because poly(lactic acid) is higher than 55 ℃ or can automatic classifying under the effect of oxygen enrichment and microorganism in envrionment temperature, in the environment of polylactic acid film after discarded after discarded, can guarantee to degrade; 3, add the same waste plastic bag product grain of this character of recovery and can be salvaged, play in process of production the reduction viscosity simultaneously, stablize the effect of inflation film manufacturing machine operation.
