Description
Technical field
The present invention relates to a kind of macromolecular material, particularly, relate to a kind of high temperature resistant degradable high polymer material and its preparation method.
Background technology
Photodegradation, light, bio-degradable are arranged at present, contain the manufacturing technology of several degradative plastic films such as oxygen degraded, thermal destruction, biological degradation.But since mulch film need be in different areas, different weather condition, different edatopes, different works
The function of thing type, different insulation, soil moisture conservation, weed eradication is wanted and can be degraded on time, can not step back degraded, can not degrade in advance.So to degradative plastic film to accomplish " suit measures to local conditions, a district one side, precisely use, degraded fully, controlling cycle " technical requirements because difficulty is big, production cost is higher, rarely has the degradative plastic film product of success so far on the market.
Biodegradable mulch mainly contains natural polymer subtype, microorganism synthesis type, synthetic type three major types.
The natural polymer subtype according to structure and composition, can be divided into natural protein, polysaccharide and derivative thereof by a class macromole that directly obtains in extraction or the physical environment in the organism, comprises some biosynthesizing polyester in addition.Typical protein, polysaccharose substance and derivative thereof have natural polymers such as collagen, glue, cyclodextrin, starch, dextran, shell chitose, hyaluronic acid, Mierocrystalline cellulose, Lalgine derivative, chondroitin sulfate and heparin at the occurring in nature aboundresources, but self-sow also, have excellent biological compatibility and degradability, the product of natural decomposition can be described as totally nontoxic, but because major part contains great amount of hydroxy group and other polar group in these molecules, easily form intramolecularly and intermolecular hydrogen bonding, thereby be difficult to dissolving and melt-processed; Also lack good water tolerance and snappiness, film thickness is higher, and mechanical property is relatively poor.The microorganism synthesis type is the macromolecular material that obtains by microbial fermentation, mainly comprises poly-β-butyric ester (PHB), poly-hydroxyl valerate etc., and they belong to PHA (PHA).Wherein, polyhydroxybutyrate is the low toxicity material, has been used to medicine controlled releasing, suture line and artificial skin etc. at present.But its microorganism growth cycle is long, productive rate is not high; Bacterial classification is low to the absorption transformation efficiency of carbon source; Polymer molecule mass distribution a wider range, and wayward; Performance is compared with the chemical industry synthetic plastics, and big gap is still arranged, and is unsuitable for the service requirements of agricultural mulching.The synthetic type is to introduce aliphatic polyester and a spot of aromatic polyester of ester group in molecular structure mostly, and its preparation method mainly comprises condensation polymerization and ring-opening polymerization.The aromatic polyester of having developed at present such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), Poly(Trimethylene Terephthalate) (PTT) wait the characteristics such as erosion that this kind polyester water tolerance is strong, can resist bacterium, can't biodegrade under the Nature condition.Aliphatic polyester series is as poly-3-hydroxyalkanoate (PHA), poly butylene succinate (PBS) etc., this class aliphatic polyester series receives publicity day by day with characteristics such as its excellent biological compatibility, biological degradabilities, use in fields such as biomedical material, injection-molded items, but in practicalization, also have some shortcomings: as price comparison costliness, biodegradation rate too fast, thermally-stabilised bad, mechanical property is relatively poor relatively, facile hydrolysis, easy aging, the more high shortcoming of foreign matter content, thereby limited the application of this kind polyester material in some field.Price comparison costliness, molecular weight as this class copolyesters such as poly terephthalic acid succinic acid-butanediol esters is lower, the degree of branching is lower, degree of crystallinity is lower, be not easy to shortcomings such as process for processing, restriction too the application of this class copolyesters in some field.For this reason, by to introducing rigidity, fusing point that aromatic components can improve copolyesters, improving its mechanical property; Can improve molecular weight and the degree of branching of copolyesters to the modification of copolyesters by chainextender, the one class copolyesters of can obtain a class moderate cost, excellent performance, be convenient to process for processing, biodegradation rate is controlled, being one of emphasis of polyester macromolecular material development, also is simultaneously to solve residual film to cause one of important method of white pollution.
