Description
Technical field
The invention belongs to chemical field and relate to a kind of Masterbatch and preparation method thereof, relate in particular to a kind of non-petroleum base degradable Masterbatch and preparation method thereof
Background technology
In in the past nearly 100 years, macromolecular material industry has obtained the development of advancing by leaps and bounds.The application of synthesized polymer material and development are very easy to people's life, and still, a large amount of uses of disposable non-degradable goods have but brought the serious environmental pollution problem." white pollution " problem has caused global concern; Various countries drop into manpower one after another, financial resources are carried out the research and development of full-biodegradable material; Through the development of recent two decades, the research and development of Wholly-degradable material have nowadays been made significant headway, and the degradable material goods are accepted by people because of its degradation property, the feature of environmental protection gradually fully; Get their way into people's lives, certain function has been played in the solution of " white pollution " problem.The complete biodegradable performance is the characteristic of this based article; With the prior resin in petroleum base source is that the Masterbatch of carrier can not satisfy this based article in the requirement of processing coloring process to degradation property, and therefore exploitation is that the colour batch of carrier has good using value with degradable material fully.And the patent of this respect is very few, and this patent is to realize that really Wholly-degradable material still possesses the important invention of degradation characteristic fully behind the painted formation goods of processing.
Patent CN1368516, used carrier is non-degradable materials such as Vilaterm or ethylene-vinyl acetate in Masterbatch that CN101392078, CN101319068 etc. provide and preparation method thereof; Patent CN101475695 provides a kind of Wholly-degradable primary color master batch and preparation method thereof, and in the non-degradable analog assistants such as polyethylene wax, OPE, paraffin, white oil one or more are arranged in this Masterbatch formula system.This Masterbatch formula system is too complicated, and small molecules auxiliary agent kind is many and accounting is many, can influence the Wholly-degradable material processing products, and there is certain risk in problem such as cause that small molecules is separated out easily.CN102040814A provides a kind of black agglomerate that is exclusively used in polylactic acid based degradable plastics; Formula system contains petroleum base non-degradable auxiliary agents such as polyethylene wax, ethene-vinyl acetate wax and EBS equally, can't realize Masterbatch degraded fully truly.
Degradable material has experienced the development from " degradable " to " high-fall separating "; Part degradation material such as starch filled Vestolen PP 7052 or polythene material; Just the starch part can be degraded; The Masterbatch of therefore traditional with the Vilaterm is carrier can use in this type degradation material goods; But nowadays degradable material has developed into the degradable material stage fully, and the color master-batch of these degradable material goods of will demanding perfection also should possess fully the performance of degraded, however now on the market and above-mentioned disclosed several patents all do not realize Masterbatch can degrade fully on moity.
Summary of the invention
Embodiment of the invention technical problem to be solved is; A kind of non-petroleum base Masterbatch and preparation method thereof of can degrading fully is provided; Employing degradable material fully is a carrier, does not add any petroleum base and non-degradable auxiliary agent, relies on advanced production technique and equipment to make the Masterbatch of can degrading fully; Really make the Wholly-degradable material goods after painted, still keep its characteristic of degrading fully, comprise the recipe ingredient of following weight percent:
Carrier 30 as one kind % ~ 50%
Pigment 20% ~ 70%
Stopping composition 0 ~ 60%,
Wherein, said carrier is a bio-based degradation polymer fully, and said bio-based degradation polymer fully comprises among polyhydroxyalkanoate PHA series, polylactic acid PLA and the poly butylene succinate PBS one or both.
The P3/4HB of said polyhydroxyalkanoate PHA series for having better mechanical property, wherein, said 4HB component concentration is 10% ~ 20%.
Preferably, said polyhydroxyalkanoate PHA series is synthetic through biological fermentation process, and said poly butylene succinate PBS obtains bio-based Succinic Acid and butyleneglycol monomer through fermentation, and is synthetic through biological process again.
Preferable, the pigment dyestuff that said pigment comprises white titanium pigment, carbon black and comprises P.B., P.Y. and P.R. different colours series.
Said stopping composition comprises one or both in starch, lime carbonate, talcum powder and the permanent white, and fineness is 800 ~ 2500 orders.
