Description
Technical field
The invention belongs to macromolecular material and prepare the technical field of film, particularly a kind of preparation method of the polymer blended film based on biological material.
Background technology
Every year is butchered a large amount of livestocks and bird by China, discharges a large amount of cutting offals.Poultry hair, feather, coffin, angle fleece, epidermis, toenail etc. are arranged, these cutting offals if processing be not good at not only polluting the environment but also can cause the waste of resource.Government department continues to increase the attention that cutting offals is handled problems in recent years, has put into effect some positive policies.Cutting offals is comprehensive development and utilization how, is problem anxious to be solved at present.
Contain a large amount of Keratin sulfate in the feather of bird, existing people is with chemical Treatment through taking suitable disposal methods cutting offals substantially both at home and abroad at present, can be divided into acid-alkali treatment method, reduction method, oxidation style etc. by biology.When carrying out the chemical Treatment cutting offals, often add reagent such as a certain amount of denaturing agent, tensio-active agent, wait with reactive force, hydrogen bond between the saboteur and handle cutting offals, but agents useful for same pollutes environment.
Along with the raising of scientific and technological level, spent high molecular material realizes that the greenization utilization of the closed cycle of energy and resource has a extensive future, and using value is also increasing.Have only the recycle of abundant exploitation macromolecular material, just can make macromolecular material really become the material friendly to physical environment, this is for can biological sustainable development having extremely important and profound significance.
Synthetic macromolecule has low price; Processing is simple; Synthon are except having the general high-performance of man-made fiber, like intensity height, light weight, quick-drying washable, good springiness, be not afraid of characteristics such as mould moth, bring great convenience to the human lives; Application aborning is also very extensive, but the overwhelming majority can not be degraded at occurring in nature as natural fiber.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of the polymer blended film based on biological material.The ionic liquid that the present invention selected for use can be as the solvent of Keratin sulfate such as poultry feather and hair, chitin, synthetic high polymer; Utilize the present invention; Need not auxiliary agents such as other modifying agents, tensio-active agent during the preparation blend film; Preparation blend film solvent composition is very simple, is ionic liquid in principle.So the simple process cutting offals does not produce auxiliary agent and pollutes, and solves the pollution problem of waste water.Therefore, various materials not only can keep self original advantages in the film through blend machine-shaping, can also combine through the interaction between the differing mol, and various mutual supplement with each other's advantages, thereby obtain superior polymer blended film.The inventive method technology is simple, and is easy to operate, and green non-pollution is to staff and environmental friendliness.
The preparation method of a kind of polymer blended film based on biological material of the present invention is following:
(1) poultry feather, hair or chitin and synthetic high polymer is clean with water rinse, clean with organic alcohol again, bake and be dried to constant weight;
(2) with poultry feather 40-96%, synthetic high polymer 4-60% and ionic liquid; Hair 10-95%, synthetic high polymer 5-90% and ionic liquid or chitin 25-95%, synthetic high polymer 5-75% and ionic liquid mix; At room temperature to 130 ℃ following dissolving 10min-10h; Being mixed with solute total mass mark is the solution of 2-50%, and above-mentioned per-cent is mass percent;
(3) above-mentioned gained solution is transferred in the container; Temperature in room temperature to 80 ℃; Film forming after the deaeration under the pressure 0.01MPa-0.1MPa condition; Prepared film is put into the precipitation bath film-forming that temperature is a room temperature to 90 ℃, solidifies the back and takes out washing, dries the polymer blended film that promptly obtains based on biological material.
Poultry feather in the said step (1) is selected from chicken feather, drake feather or goose feather.
Chitin in the said step (1) is selected from shrimp shell or crab shell.
Hair in the said step (1) is an animal hair, is selected from that the people sends out, wool, pig hair, ox hair, the rabbit hair, horsetail hair or yak hair.
Synthetic high polymer in the said step (1) is the aliphatic polyester family macromolecule, is selected from POLYACTIC ACID (PLA), Z 150PH (PVA), lactic acid-caprolactone copolymer, glycolide-lactide copolymer or caprolactone-copolyether.
Organic alcohol in the said step (1) is methyl alcohol, ethanol or Virahol.
Ionic liquid in the said step (2) is imidazoles, pyridine or benzoglyoxaline ionic liquid.
Precipitation bath in the said step (3) is one or more in deionized water, tap water, the alcohol.
When described precipitation bath was a deionized water with the mixing solutions of the mixing solutions of alcohol or tap water and alcohol, pure volumn concentration was 1-99%.
To existing problem in the background technology, the present invention proposes a kind of method of the polymer blended film based on biological material.Utilize the present invention, need not auxiliary agents such as other modifying agents, tensio-active agent during the preparation blend film, preparation blend film solvent composition is very simple, is ionic liquid in principle.With synthetic high polymer, poultry hair, feather, coffin, angle fleece, epidermis, toenail etc. and ionic liquid; Or synthetic high polymer, hair and ionic liquid; Or but synthetic high polymer, chitin and ionic liquid mix, and under temperature action, forms mixed solution, and mixed solution is poured on the film-forming plates; And then after vacuum defoamation film forming; Made mixing solutions is placed in the suitable containers, puts into suitable precipitation bath film-forming again, solidify back taking-up washing and dry the polymer blended film that promptly gets based on biological material.So the simple process cutting offals does not produce auxiliary agent and pollutes, and solves the pollution problem of waste water.
Specifically; The present invention design provides a kind of preparation method of the polymer blended film based on biological material; Promptly using above-mentioned ionic liquid is that solvent dissolves synthetic high polymer, poultry hair, feather, coffin, angle fleece, epidermis, toenail, human hair, chitin etc., and the mixing solutions that dissolves back formation is carried out film forming.
When the preparation blend film, only contain required synthetic high polymer, poultry hair, feather, coffin, angle fleece, epidermis, toenail, human hair, chitin and ionic liquid in the mixing solutions.Can under the experiment condition of routine, implement, with this understanding, the solubleness of cutting offals in time, temperature and changing, can be biological in order to controlling solubleness with time and temperature.
Beneficial effect
