Description
Technical field
The present invention relates to a kind of Rhizoma amorphophalli glucomannan/polyester composite and preparation method thereof, belong to the polymer material science field, also belong to the natural polymer field.
Background technology
Because consuming day by day and environmental pollution that finished product cause of petroleum resources, come into one's own day by day based on the research of the type material of renewable biomass resource, wherein natural polymer is the important biomass resource of a class.Type material mainly is meant the sort of meeting both in use to have good mechanical property, satisfies various different demands, can be degraded to small-molecule substance water after using again, the material that carbonic acid gas requires.Degradation material is by various ways such as photodegradation, chemical degradation, biological degradation degradeds, contain usually hydrolyzable functional group (as, ester bond, urea key, amido linkage, ehter bond etc.), comprise synthetic material and natural materials.The synthesis and degradation material comprises poly(lactic acid), polycaprolactone, poly-hydroxyalkyl acrylate etc., and natural polysaccharide is a kind of natural important carbohydrate that is present in, and comprises Mierocrystalline cellulose, starch etc.At present, by their the preparation the natural polysaccharide nano whisker and platelet successfully enhancing modified rubber (Biomacromolecules 2006,6,612; Biomacromolecules 2003,4, and 1835; Macromolecules 2005,38,3783), (Biomacromolecules 2006 for starch plastic, 7,531), (Biomacromolecules 2005 for the poly(lactic acid) plastics, 6,3160), (Macromolecules 2002 for polycaprolactone, 35,2190), (Polymer 2005 for polyvinyl alcohol, 46,5637), polypropylene, polyvinyl chloride, plastic of soybean protein etc., what be worth especially proposing is that the starch nano platelet that extracts from starch is also demonstrating tangible reinforced effects with the starch plastic compound tense.The concern of and physical environment constantly healthy to self along with people feasiblely more and more is subjected to people's attention based on biological material and derivative thereof and composite study, exploitation, utilization.
Konjaku is the characteristic resources of China, and Hubei is the big province of konjaku plantation, has numerous konjaku planting bases and konjaku powder processing enterprise.Along with United Nations's food sanitation tissue is freely sold the passing through of bill as protection food in the whole world to konjaku, US and European market is open to it in succession, the world market of konjaku product is constantly expanded, and nearest 10 years of relevant rudimentary and applied research are noticeable gradually abroad.China's konjaku outlet only limits to raw material now, and profit is meagre, and added value of product is low.The main component of konjaku powder is Rhizoma amorphophalli glucomannan (KGM), is the natural polysaccharide that a kind of main chain is made up of the glucose and the seminose of the connection of β-1,4 pyranose glycosidic bond.Up to now, about the research of KGM focus mostly on extraction, structural analysis and the sign of KGM, bromatology character (as rheological, gelling, thickening property etc.), physico-chemical property, as the working method of food, medicinal and nourishing function, physics or chemical modification etc., institute's development product kind is few and of low grade, and the application of achievement in research conversion is very limited.The deep level development of KGM and the expansion of Application Areas still need a large amount of work.
Summary of the invention
But the object of the present invention is to provide a kind of hydrophobic thermoplastic, biodegradable Rhizoma amorphophalli glucomannan/polyester composite and preparation method thereof.
To achieve these goals, the technical solution adopted in the present invention is as follows: a kind of Rhizoma amorphophalli glucomannan/polyester composite, it is characterized in that it is prepared from by Rhizoma amorphophalli glucomannan and polyester raw material, the shared weight percent of each raw material is: Rhizoma amorphophalli glucomannan 1-65%, polyester 35-99%.
Described polyester comprises: poly(lactic acid), polycaprolactone or poly-hydroxyalkyl acrylate.
Described poly(lactic acid) is poly-D-lactic acid (PDLA), poly (l-lactic acid) (PLLA) or poly-DL-lactic acid (PDLLA).
Described poly-hydroxyalkyl acrylate is poly butyric ester or poly-hydroxyl valerate etc.
The preparation method of above-mentioned a kind of Rhizoma amorphophalli glucomannan/polyester composite is characterized in that it comprises the steps:
1). by the shared weight percent of each raw material be: Rhizoma amorphophalli glucomannan 1-65%, polyester 35-99%, choose Rhizoma amorphophalli glucomannan and polyester is standby; 2). with Banbury mixer or screw extrusion press with Rhizoma amorphophalli glucomannan and polyester melt blending, moulding, Rhizoma amorphophalli glucomannan/polyester composite.
The temperature range of described melt blending is 60-200 ℃ (blending temperature is higher than the melt temperature of polyester, because of polyester type different), and the rotating speed of melt blending is 50-200rpm, and the time of melt blending is 5-30min.
Describedly be shaped to injection moulding, extrude or hot-forming.The temperature range of described hot pressing or injection moulding be 60-200 ℃ (because of polyester type different), the pressure of hot pressing or injection moulding is 20-80MPa, the time of hot pressing or injection moulding is 5-20min.
The present invention utilizes biodegradable polyesters and Rhizoma amorphophalli glucomannan melt blending, but prepares hydrophobic thermoplastic, the matrix material of biological decomposition (biodegradable) fully.The present invention has that cost is low, environmental protection, technology characteristic of simple, but prepared Rhizoma amorphophalli glucomannan/polyester composite has hydrophobic thermoplastic, biodegradable characteristics.
